Warmup the leading ISO 9001 UK manufacturer and supplier of the world’s best selling floor heating have developed a complete set of floor heating solutions and knowledge to ensure a perfect system for your floor.

We understand that installing underfloor heating in conjunction with wood flooring requires consideration. We know you will be delighted with the result.

Key floor heating benefits Design freedom – underfloor heating is a designer’s dream, no bulky radiators to take up valuable wall and floor space

Energy efficiency - underfloor heating gives the user control - it requires significantly less energy as you are not heating the ceiling area and it enables the temperature of each room to be accurately controlled as needed, allowing end users to heat the rooms they want – when they want, with no energy wasted

Cost savings – because underfloor heating produces less convected heat than standard radiators, heating costs are reduced and savings of as much as 10% can be achieved on heating bills

Health benefits – underfloor heating reduces humidity preventing dust mites from surviving and the radiant heat it gives out reduces dust circulation – these are important features for those who suffer from allergies and asthma

Water systems can be linked to any heat source, giving total flexibility - allowing for best energy savings, now and in the future

Little or no maintenance - there is no maintenance required for electrical systems. For hydronic systems, all electrical components are designed for multiple use and longevity; serviceable parts are easily replaced should the need arise

Laars Krüger, Lead Research Engineer. Warmup Research Centre - Bremen, Germany


Warmup Monitored Family Homes Programme The Warmup Monitored Family Homes Programme grew out of the need to better predict the future energy running costs of houses using Warmup underfloor heating systems. Warmup monitors 9 occupied houses and offices with 644 sensors, taking 927,360 reading daily equating to 338 million readings per year. This information can also be checked and compared with the information provided by the Warmup Research Centre in Germany to create a highly predictive model that allows all manner of key questions to be answered from:

“How much will it cost to run the heating system of my new, yet to be built house?” to “How much will I save using Warmup radiant underfloor heating rather than radiators in this house?”

Information is gathered every few minutes from many tiny sensors. These are strategically placed in each zone to compare floor, air, wire/water and outside temperatures and often other readings like humidity and radiant temperature. This allows a detailed view

of the amount of energy actually needed to create ideal living conditions.

This can be compared with test facility results and in particular, what may have been predicted by the SAP (Standard Assessment Procedure used by the Department of Energy and Climate Change), calculations which are central to the perceived energy performance and efficiency of a dwelling.

SAP, whilst being integral to the construction process of domestic dwellings, by necessity has to be a calculation that can be applied across a range of circumstances with different input variables and assumptions.

The information and analysis from the Warmup Research Centre and post occupancy monitored housing programme is at your disposal to assist in the design phase for your project.

Warmup underfloor heating is showcased in the BRE Renewable House to deliver low CO2 emissions, including both embodied carbon and low energy usage. It is proving the perfect system for sustainable CSH Level 4 homes. These need very little space heating applied through precise, zoned and accurate controls.

It is also demonstrating how healthier living is achieved by avoiding the creation of cold air currents at floor level and temperature build-up at ceiling level, associated with convection heating air currents.

One of Warmup’s post occupancy monitored houses is situated in Berkshire. It is a 470 sqm CSH Level 4 house with a 4 person family.

When it comes to running costs, our test studies found that during the Winter of 2010 - 2011 the average running costs (Oct-Feb) were 2.16 pence per sqm per day.

Whereas during the Winter of 2011-2012 the average running costs were 1.47 pence per sqm per day.

This saving of 32% was created by post system commissioning adjustments by Warmup and on going technical assistance for optimising performance and energy costs.

The Cost of Running a Warmup Heating System

Morning

Warmup allows you to control fuel costs - zoning your homeAdding a zone to your house is as simple as adding a thermostat. Unlike traditional heating systems, i.e., gas central heating that run all the rooms of your house at once, whether you are using them or not, underfloor heating systems can be set to heat individual rooms where and when you need it (for example, a bathroom for an hour and a half in the morning). By tailoring your system usage according to your lifestyle, you can enjoy more substantial savings with increased comfort.

When planning a heating solution one of the considerations is how much it will cost to purchase, install and run. Another important consideration is how much maintenance is involved and the associated cost.

Many people assume that running a whole-house underfloor heating system will be more expensive than an traditional radiator system, but this is not the case.

Running cost informationRunning costs will always depend on the room size and the running time, as well as how well the room is insulated. To get an accurate idea of typical running costs, see the table and notes below:

Accuracy of running costsWe test our heating systems, running under normal operating conditions within a test environment, built to EN442-2 standard specifications. The data collected from this extensive testing allows us to state with certainty, exactly what the operating costs are under these conditions.

Please note that these tests are performed using Warmup Systems and that this data is accurate for Warmup Systems only.

Assumptions and variablesTo calculate accurate running costs, we have made the following assumptions:

1. Installation is in a house built to current Part L regulations

2. Heaters used: 150W/m2 mats, under 8-10mm ceramic tile on 10mm Warmup Insulation Board

3. The temperature difference between “on” and “standby” is 5°C (e.g. 16°C when on “standby”, 21°C when “on”)

4. The floor coverage is consistent to property size (e.g. 5m2 of heating for a 5m2 room)

5. The heat-up time is included within the hours ON

6. The heating is controlled by a Warmup thermostat

7. Price per kWh is 12.66p (UK electricity price available - June, 2015)

Save money by insulating properly and reducing heat-up times:

During the heat-up period, as the floor reaches its set temperature, the heating system is running at full power. After this period, the heating system needs to run at approximately half-power to maintain the set temperature. Simply put, the faster the floor heats-up, the cheaper the system is to run.

By properly insulating your floor with Warmup Insulation Board, you can reduce the heat-up period significantly, thereby reducing running costs by as much as 50%.

Suitability of floor for underfloor

heatingBefore ordering the wood flooring, check that the selected flooring is compatible with underfloor heating.

UnderlayFor floating floors we recommend to use a specialist wood floor underlay over underfloor heating. Such underlays typically have a thermal resistance of 0.3 tog. The maximum tog rating of all materials above the floor heating system, including the floor, should not exceed 2.5.

InsulationAlways use suitable insulation under the underfloor heating system. Proper insulation will reduce heat-up times and keep running costs to a minimum. Warmup supplies a number of suitable insulation types. (Please ask in-store, contact Warmup on 0845 345 2288 or visit www.warmup.co.uk)

Thickness & density of wood

flooring

Wood conducts less heat than stone or tiles, so the thinner it is, the higher the output of the system and the faster the heat-up time. The maximum thickness for efficient heat output is about 18mm but thicker boards can be used at a lower ouput. The density of the wood flooring will also influence the heat transfer of the underfloor heating system. Higher density floors transmit heat better.

Level tolerances

All sub-floors must be flattened to the following tolerances:

• Thin plank flooring: +/- 3mm per 2 linear metres in all directions.

• Wide plank flooring: +/- 3mm per 2 linear metres in all directions.

• Patterned floor (e.g. Parquet): +/- 2mm per 3 linear metres in all directions.

Cement screed subfloors

Cement screed subfloors must have a moisture content of less than 3% and a relative humidity (ErH) of less than 75%. Anhydrite screed must have a moisture content less than 0.3%. Measurements can be taken 48 hours after any heating systems and dehumidifiers have been switched off, using a BS 8203 hygrometer.

Hygrometer testing involves the drilling of a 16mm (width) x 50mm (depth) hole into the screed by the subfloor contractor. The contractor should then insert a protimeter humidity sleeve into it; one test must be conducted for every 5 square metres. The subfloor contractor must take special care to avoid damage to the underfloor heating, plumbing or electrical components beneath the surface of the screed.

Fast dry and rapid set screed and self-levelling compounds can accelerate the time taken to achieve the correct moisture levels.

Joist & plywood subfloors

If fixing plywood to joists, the plywood must have a minimum thickness of 18mm and be screwed to the joists at 300 - 400mm centers. Sheets must have a moisture content of less than 10%.

All sheet joints must be laid in a staggered, “brickwork” pattern. Sheets must not be joined at door thresholds; a single sheet must traverse the threshold.

Expansion gapsAn expansion gap should always be left around the perimeter of the floor, in doorways between rooms and at all vertical surfaces. This is typically between 10 - 30mm. Ask your flooring supplier for more details particular to your floor. If the floor is greater than 5m wide, it is advisable to leave a gap of about 2mm every 6 - 7 rows to allow for extra expansion.

Letting your flooring

acclimatise

The wood flooring should be stored in the building to acclimatise during the heating systems pre-floor installation heating cycle also follow the flooring manufacturer’s guidelines.

During installation it is recommended that the floor surface temperature should be maintained at 15°C. The air temperature should be maintained between 15 - 22°C and the atmospheric relative humidity between 40 - 60%. After installation, allow the floor to acclimatise for at least 48 hours before turning the system back on. Typically limit the initial floor temperature to 15°C and increase by 1°C a day until the desired floor temperature is achieved. Check this procedure with your flooring supplier as the ambient temperatures will vary depending on the time of year the installation takes place.

Moisture content of the wood flooring

Engineered wood is more stable than solid wood but it is important for both types that the moisture content is typically between 10 - 11% when laid, which will reduce to 8 - 9% when heated. Check with your supplier or manufacturer when ordering and ensure that the flooring is transported and stored in a dry environment.

Pre-installation heating cycle

The heating system should be activated and the temperature increased in daily increments of 5°C, i.e. day one 5°C, day two 10°C, day three 15°C until the maximum floor temperature of 27°C is reached.

The maximum temperature should be maintained for at least 48 hours or in the case of cement screed, until the correct screed moisture levels are achieved (See cement screed).

The heating system should then be cooled observing the same 5°C adjustments per day.

When the heating system has returned to the lowest level, switch the heating system off for 48 hours.

Re-activate the heating system and once again increase the temperature by 5°C per day until the installation surface temperature of the sub-floor of 15°C is reached. 15°C should be maintained throughout the installation period. Ambient temperatures depending on the time of year of installation may not permit the 15°C to be maintained. Consult with the flooring manufacturer on how best to proceed.

NOTE: The heating system should not be operated until any floor protection has been removed.

Relative humidity of the room

The moisture content of the air indoors will be affected by the outdoor climate and humidity gradients will affect how much moisture wood will absorb. Wood is a hygroscopic material and these variations can lead to shrinkage and expansion accordingly. Air humidity is expressed as a percentage of maximum humidity of air at saturation point and should be maintained typically between 40% and 60%.

During installation, the atmospheric relative humidity (RH) should not fall below 40% or exceed 60%. Room temperatures must not fall below 10°C. The floor post installation should maintain the same relative humidity levels. When radiant underfloor heating systems are used, the system must be properly regulated to ensure that the floor surface temperature does not exceed 27°C.

Heating controls

Heated wood floors need systems that can be controlled accurately. Warmup offers a comprehensive range of bespoke controls. This includes the patented 3iE Energy- Monitor Thermostat and Tempo™ Programmable Thermostat.

The 3iE Energy Monitor Thermostat is designed to be easy to use, with no manuals needed. It is the first thermostat with a 2.4” full colour screen and a clear graphic interface. The Proportional Adaptive Function precisely activates the system only when needed.

Its clear graphic interface shows energy usage and prompts users to save up to 10% on utility bills. The unrivalled accurate floor temperature control means no wasted energy - reducing the costs associated with over-heating.

The Tempo™ Programmable Thermostat is an easy-to-use interface and intuitive design. The four-step programme is fast and simple. It provides temperature accuracy for comfort with no wasted energy.

Wattage density The type of heating system best suited for a wood floor application often involves the complex analysis of space limitations, variety of wood and flooring type and thickness, as well as insulation levels of the building for heat loss considerations - Warmup will advise you on the best solution.

Maximum floor temperature

Wood floors should not be heated above 27°C. The room thermostat should have a floor probe(s) which automatically controls the underfloor heating, so that the temperature does not exceed 27°C. The Warmup 3iE Energy-Monitor Thermostat and Tempo Programmable Thermostat offers this capability.

New-build Refurbishments

Hydronic systems are often used in new-build projects, or major refurbishments such as extensions where the subfloor build height is not an issue. Hydronic systems (i.e. water-based) are also fully compatible with renewable heat sources such as air source heat pumps and solar water heating. The pipes are covered with screed and once dry (which can take several weeks), the floor acts as a thermal mass. The system must be dry and operational before laying the wood flooring.

The Warmup Inscreed Cable System, a 6mm heating cable protected by multiple layers of metal shielding and insulation, is also ideal for installation within screeded floors of any size.

Electric systems are typically used in refurbishment projects due to their low build height and simple installation. The lightweight build required for electric system subfloors means they do not raise floor levels significantly. They are ideal for “hybrid” installations where a hydronic system is installed on the ground floor and electric on upper floors.

It is possible to use a specialist wood floor underlay over underfloor heating, but you must ensure it is thin and not the foil-reflective type. The maximum TOG rating of all materials above the floor heating system, including the floor, should not exceed 2.5.

Wood Floor Type(i.e. the finished decorative floor)

Many of today’s wood floor varieties are compatible with underfloor heating, but remember to ask when selecting your chosen flooring.

Always ensure your wood flooring has acclimitised in the room before installing.

Is available in both soft and hardwood, made from a single piece of timber. It is very susceptible to humidity and temperature change and can be prone to gapping, cupping and crowning. Some types of solid wood are available which are compatible with underfloor heating.

Always check with the flooring supplier before ordering.

Is constructed from several layers (typically three) of wood, bonded together in the form of a plank.

The layers are bonded together with the grain of each layer at 90o to the adjacent layer to give dimensional stability. The top wear layer is hardwood, typically 4-5mm thick. The core and bottom layers are often soft woods such as pine. Engineered wood is less susceptible to the affects of moisture and temperature change and most types are very suitable for use with underfloor heating.


Are similar to engineered wood in construction but the top layer is a thin veneer bonded to a composite core with a plywood bottom layer, such as birch.

Ply-backed multi layer floors are very stable and many high quality types are suitable for use with underfloor heating.

Where engineered wood typically uses ply in its construction, high-quality multi-layer flooring typically uses same-type solid wood throughout.


Refers to the design of the floor and is a series of small wood blocks normally laid in a herringbone pattern. Parquet flooring is available in various types of either solid wood or engineered wood and many are suitable for underfloor heating.


Are a multi-layer synthetic floor in plank form made to simulate wood. It normally has an HDF (High Density Fibre) core. The top floor design layer is a high resolution photo of real wood, finished with melamine resin to produce a very real and natural look. This is covered with a wear resistant layer pressed onto the HDF board, making it resistant to stains, wear, impact and scratches. Laminate flooring is easy to lay, cost effective and most types are suitable for use with underfloor heating.

Warmup Heating SystemsWarmup underfloor heating offers the most complete, flexible and safe heating solution for wood floors.

All Warmup products are designed and manufactured in our world-class facilities with a reputation for innovation, quality and excellence.

Electric underfloor heatingWarmup electric underfloor heating, the world’s best-selling electric floor heating brand™, provides warmth throughout the whole room, giving a whole new meaning to heating and comfort. Warmup’s electric underfloor systems use BEAB-approved ultra-thin heating elements, with tough fluoropolymer coatings, is the thinnest wire you can buy (less than 1.8mm thick) and will not raise floor levels. This also makes it much easier to install particularly in upper floor rooms (e.g., bathrooms).

The Warmup Foil Heating System is a super thin fully earthed flat aluminium foil designed for use under wood and laminate floors. It can be used under vinyl and carpet floors when combined with Warmup Insulated Underlay and Dual Overlay.

The Warmup Inscreed Cable System is designed for installation in 50 to 100mm of concrete screed. Once installed the heated screed can be covered with any flooring.

When it comes to installation, Warmup electric underfloor heating is easy to install. A qualified electrician is required to fit the thermostat, RCD and final connection to the power supply.

To provide additional security and peace of mind, Warmup was the first manufacturer to guarantee its products for life and goes one step further through its SafetyNet™ Installation Guarantee, this means if the wire is accidentally damaged during installation, Warmup will replace it free of charge – this is unique to Warmup.

Warmup’s 3iE Energy-Monitor Thermostat has settings for different floor coverings, including wood. The wood setting prevents the floor temperature from exceeding 27°C, so there is no danger of warping or damage to the floor through overheating.

Hydronic underfloor heatingWarmup hydronic heating systems are particularly suitable for new build projects. The heating system operates by circulating warm water through pipes including PEX-A (cross linked polyethylene) and multi-layer composite AL-PERT pipes. These are installed in a conductive floor structure (screed), or in conductive elements (diffusion plates), which are embedded into the subfloor to transfer the heat to the floor surface. The floor becomes a large low-temperature heat emitter, warming the floor surface and transferring heat to the room or space.

The major method of heat transfer from the heated floor surface is by radiation, it amounts to 50%-60% of the output; the remainder is made up by convection and conduction. Further, having slightly warmer feet than the head leads to better comfort conditions.

Unlike radiators, hydronic underfloor heating systems do not need to run at a high temperature. Typically, the temperature of the water in an underfloor heating system pipe is 35-55°C, warming the floor to a temperature of 27°C as opposed to the c.80°C flow and surface temperature of a radiator system.

Room temperature is controlled by Warmup’s bespoke 3iE Energy-Monitor Thermostat. In the case of multi-zone installations, i.e. multiple rooms in the building or home using hydronic underfloor heating; a central wiring system is used where the thermostats are controlled depending on the specific heating output required per zone.

Fixing Method: Stapled/Nailed Floors

Concrete subfloor

The Loose Wire solution is recommended for secret nailed floors where floor height is an issue.

Battens, with a minimum height of 30mm and a width of 50mm, should be fitted to the existing concrete subfloor, above a damp proof membrane. The battens should be fitted at either 300mm or 400mm centres when the cable is installed at 100mm centres. If the cable is installed at a different spacing, change the batten spacing accordingly. Next, fix Warmup Insulation Board between the battens, finishing 10mm below their tops, before laying the Loose Wire heater on the insulation board.

The heater must be routed through notches in the battens, before being covered with a 10mm layer of self-levelling compound which must finish flush with the top of the battens. This creates a level surface on which to install the wood flooring. Check the heater before laying the self-levelling compound.

An optional thin wood floor underlay, suitable for electric underfloor heating, can now be laid over the self-levelling compound. Lay the wood floor on the self-levelled surface and nail or staple into the battens below, keeping the boards perpendicular to the battens.

Allow an expansion gap around the edge of the floor. This is typically between 10 - 30mm; ask your flooring supplier for more details particular to your floor.

Some manufacturers recommend a maximum board width of 150mm for nailed floors. Check with your flooring supplier before installation.

This Inscreed Cable solution may be used for installations in new-build projects where subfloor height is not an issue and where the flooring is to be secured with nails. The screed will store the generated heat allowing for more cost effective energy use.

Battens, with a minimum height of 60mm and a width of 50mm, should be fitted to the existing concrete subfloor, above a damp proof membrane. The battens should be kiln dried and fitted at either 300mm or 400mm centres when the cable is installed at 100mm centres. If the cable is installed at a different spacing, change

the batten spacing accordingly. Install at least 10mm of rigid insulation board between the battens. Lay the Warmup Inscreed Heating Cable on top of the insulation and cover with a 50mm cementitious screed. The heater must be routed through notches in the battens, before being covered with a layer of cementitious screed, finishing flush with the top of the battens. This creates a level surface on which to install the wood flooring. Check the heater before laying the screed.

This system comprises of pre-formed insulation panels measuring just 16mm thick and is recommended where achieving a low profile installation is required. The aluminium diffuser plate bonded to the panel is designed to provide efficient distribution of heat.

Warmup glue is applied to a stable and prepared load bearing sub floor before the Total-16 panels are bonded in place. The 12mm PEX-A pipe is then inserted into grooves within the panels and connected to the manifold, leaving a flat surface.

Once the pipes have been pressure tested, the panels can be primed and a levelling compound can be applied leaving it ready to receive the glued timber floor finish once dry.

Some wood floor manufacturers recommend gluing a plywood substrate to the floor first and then gluing the floor to the substrate. This helps to prevent rotational movement and also facilitates replacing a board if damage occurs in the future.

Ensure an adequate expansion gap is left around the wooden floor so that it has room to grow in the more humid summer months. This is typically 10-30mm but each products requirements should be checked with its supplier.

This fixing system for Loose Wire heaters is used where it is desired to nail the wood floor down. The new wood floor can be laid over an existing floor where floor height is not a problem. Ensure the existing floor is stable, covering with a vapour barrier (DPM) if required before fixing the battens, which should have a minimum height of 30mm and a width of 50mm. The battens should be fitted at either 300mm or 400mm centres when the cable is installed at 100mm centres. If the cable is installed at a different spacing, change the batten spacing accordingly.

Next, install 20mm Warmup Insulation Board between the battens and install the Loose Wire Heater on top of

the insulation. Cover the wire with a self-levelling latex compound to finish flush with the top of the battens (minimum 8 - 10mm).

If floor height is a problem, the new floor can be laid between the existing joists. Supporting battens and a plwood sheet are fitted between the joists to support the Warmup Coated Insulation board, cable and leveling compound instead of it being built up from the existing floor deck between battens. The wire must be routed through notches in the battens, before being covered with a 10mm layer of self-levelling compound which must finish flush with the top of the battens.

This creates a level surface on which to install the wood flooring. Check the heater is working before laying the latex compound. Lay the wood floor on the self-levelled surface and nail or staple into the battens below, keeping the boards perpendicular to the battens. An optional thin wood floor underlay, suitable for electric underfloor heating, can be laid over the screeded surface. Allow for an expansion gap around the edge of the floor. This is typically between 10 - 30mm; ask your flooring supplier for more details particular to your floor.

With this system aluminium diffuser plates are used to disperse heat from the pipes.

After selecting the depth of rigid insulation panels required, fix support battens to the inside edges of the floor joists, with their top faces the depth of the insulation plus 16mm down from the top of the joists.

The rigid insulation is then placed between the joists, supported by the battens. The aluminium diffuser plates are then installed over the joists with the pipe channels supported by the insulation.

The joists need to be notched to allow for pipe runs between joists and to and from the manifold. The heating pipe is then inserted into the plate grooves according to the pre-determined circuit design.

Connect the system to the manifold and pressure test.

Install the wood floor over the heating and nail into the joists below, taking care to avoid the notched areas. Allow an expansion gap around the edge of the floor. This is typically between 10 - 30mm; ask your flooring supplier for more details particular to your floor. An optional thin wood floor underlay can be laid under the floor.

The Silva Joisted Floor system is installed in many refurbishment projects. Joists traditionally tend to be installed at 400mm centres. However, Warmup can supply a more bespoke system to suit individual properties with varying joist centres as required.

Fix support battens to the inside edges of the floor joists. They should be positioned to allow for a plywood supporting layer, a layer of Warmup Clypso Insulation and a 25-50mm screed to be installed on them, finishing flush with the top of the joists. Warmup Insulation Board is then installed between the joists supported by a layer of ply spanning between the support battens.

The joists need to be notched to allow for pipe runs between joists and to and from the manifold.

The heating pipe is then installed as per the approved design and secured by clips. Connect the system to the manifold and pressure test. Cover the pipe with a thin screed finished level with the top of the joists.

When the screed has completely dried, the system and screed needs commissioning before the wood floor can be laid and secured to the battens by secret nailing or stapling. An optional thin wood floor underlay can be laid under the floor.

Allow an expansion gap around the perimeter of the floor. This is typically between 10 - 30mm; ask your flooring supplier for more details particular to your floor.

Secure existing floorboards. If laying onto joists, install an 18mm plywood subfloor. Fix Warmup Insulation Board to the floorboards or plywood using a flexible adhesive and secure with 5 screws and washers per board.

Lay the Loose Wire, Mat or StickyMat heater onto the insulation board. Check the heater is working and then encase in 8 - 10 mm thick self-levelling latex.

The wood floor can now be glued directly to the latex surface. Allow an expansion gap around the edge of the floor. This is typically between 10 - 30mm; ask your flooring supplier for more details particular to your floor.

It is important to check the condition of the subfloor to ensure it is stable prior to gluing.

Some wood floor manufacturers recommend gluing a thin plywood substrate to the latex floor first and then gluing the wood floor to the substrate. This helps prevent rotational movement and facilitates replacing a board if damage occurs later on. Check with the flooring supplier.

Glued floors are preferred by some solid wood floor manufacturers and most manufacturers recommend an MS polymer adhesive.

This system comprises of pre-formed insulation panels measuring just 16mm thick and is recommended where achieving a low profile installation is required. The aluminium diffuser plate bonded to the panel is designed to provide efficient distribution of heat.

Warmup glue is applied to a stable and prepared load bearing sub floor before the Total-16 panels are bonded in place. The 12mm PEX-A pipe is then inserted into grooves within the panels and connected to the manifold, leaving a flat surface.

Once the pipes have been pressure tested, the panels can be primed and a levelling compound can be applied leaving it ready to receive the glued timber floor finish once dry.

Some wood floor manufacturers recommend gluing a plywood substrate to the floor first and then gluing the floor to the substrate. This helps to prevent rotational movement and also facilitates replacing a board if damage occurs in the future.

Ensure an adequate expansion gap is left around the wooden floor so that it has room to grow in the more humid summer months. This is typically 10 - 30mm but each products requirements should be checked with its supplier.
