PRODUCT INFORMATION SHEET
Icopal Tubular Washers
The Icopal Tubular Washer System offers many benefits over other traditional fastening methods.
Thermal transmittanceTraditional fastener and metal plate combinations create a path for heat loss from the inside of the building to the outside atmosphere. This seemingly small thermal bridge creates significant heat loss. This loss has to be factored in when calculating U-values to BS EN ISO 6946. This can result in an increase in the insulation thickness to compensate.
The Icopal Tubular Washer eliminates this thermal transmittance thereby allowing a reduced thickness of insulation.
Insulation thicknessRegulations are constantly being upgraded to help reduce a building’s carbon usage, leading to thicker insulation beingrequired.
Thicknesses of up to 595 mm can easily be accommodated with the Icopal Tubular Washer and Screw Fastener combination.
Eliminate unwinding forces The cyclic nature of wind uplift on flat roofing systems can cause standard fastening methods to unwind.Icopal Tubular Washers and Screw Fasteners can allow this cyclic action to occur without causing the fastener to unwind.
CompositionIcopal Tubular Washers are blue in colour and precision moulded from high grade polypropylene and extensively tested to ensure resistance to the extreme temperatures and mechanical stresses encountered within the roofing system.
Membrane protectionFoot traffic or other loads applied to the roof surface can often force the fastener head to pop through the membrane as the insulation beneath compresses. This causes damage to the waterproofing membrane and therefore potential roof leaks into the structure.
The telescopic action of a tube and fastener combination that is not locked together removes the risk of the fastener being pushed through a thin deck by foot traffic or materials being placed on the roof surface.
ProfileThe Icopal Tubular washer’s round design which together with a narrow diameter tube ensures a quick installation. They are available with two washer diameters: A 45 mm diameter for use when fixing membranes, and a 75 mm diameter for use when fixing rigid insulation boards.

PRODUCT INFORMATION SHEET
Icopal Stress Plates
There are often situations when the Icopal Tubular Washers cannot be utilised, for example when the membrane is not being fastened directly to insulation, such as in a cold roof situation, or when fastening membrane which is applied directly to a plywood overlay. For these situations the Icopal Stress Plates are used.
These plates are purpose-designed for use with fasteners from the Icopal range and are manufactured from from a high quality carbon steel.
If further advice is required please contact Icopal Limited’s Technical Services for guidance.
• Selecting the correct tube washerTo optimize the benefits of the Icopal Tubular Washer system, ideally use the maximum length of tube washer and the minimum fastener length available. In certain applications, such as over-roofing of existing membrane and insulation layers, different tube lengths may be required.
Icopal LimitedRef ICO2543
Guidance Notes examples only
The tube washer should be chosen first; then the fastener can be selected.
To select the maximum tube length (C) :
i) deduct minimum 15 mm from the total build-up of the roof insulation (A) to allow for compression of the insulation (B).
ii) choose the tube washer of that length or shorter.
eg, For an insulation buildup of 140 mm, the maximum tube length would be 125 mm, and so a 105 mm long Tube Washer would be chosen. Total Roof System build-up (A) 140 mmDeduct compression tolerance (B) -15 mmMaximum tube length 125 mm
Chosen tube length (C) 105 mm
• Selecting the correct fastener length
When selecting the correct Icopal Screw Fastener length, allow for the recommended minimum deck penetration or embedment and take into consideration the total build-up of the roof system, including any pressure plate, membrane, separation layers insulation, vapour barriers, existing systems and structural deck.
To select the optimum fastener length (F) for tube washer applications:
i) take the total roof system build-up measurement (A) and deduct the selected tube length (C).
ii) allow for deck penetration (D) and then add minimum 20 mm allowance for the fastener within the tube (E).
iii) select the fastener at this length or longer.
eg, For a 140 mm build-up over 0.7mm steel deck using a 105 mm tube the minimum fastener length would be 70 mm.
Total roof system build-up (A) 140 mmDeduct selected tube length (C) -105 mmAdd min. deck penetration/embedment (D) +15 mmAdd allowance for fastener within tube (E) +20 mm Minimum fastener length (F) 70 mm
Key: A: Total roof buildup depth B: Insulation compression tolerance ( min 15 mm) C: Tube Washer length D: minimum deck penetration or embedment E: min 20mm allowance for fastener in tube F: Fastener length
Washer/Fastener CombinationsThe following tables are provided as a quick reference guide for calculating the required tube washer and fastener combination for a new warm roof direct to deck. The thickness of structural deck used for the combination is indicated for each table. The fastener length should be altered accordingly where the structural deck thickness or system build-up is different. See previous page for further information.

Icopal Fasteners & AccessoriesA Range of Tubular Washers, Plates and Screw Fasteners
Quality AssuranceIcopal Tubular Washers, Pressure Plates and Screw Fasteners are supplied under a Quality Management System approved to ISO 9001: 2004 by Swiss Association for Quality and Management Systems.
Insulation AttachmentIcopal Thermazone PIR insulation boards should be attached at the minimum rate of 11 tubes & fasteners per 1.2 m x 2.4 m board (unless otherwise specified and approved). An increased density may be recommended depending on project location, height and exposure etc.
Membrane AttachmentFor every mechanically fastened roof, a wind uplift calculation and fastener specification will be required prior to installation of the Icopal roof waterproofing membrane. All calculations are conducted in accordance with BS 6399 or BS EN 1991 parts 1-4, as appropriate.
Fastener ApplicationNo pre-drilling is necessary for timber and steel decks. Simply insert the fastener through the tubular washer and install with a standard clutch drive electric screw gun (0 – 2500 rpm). Optimum fastener performance is achieved when fastener is installed perpendicular to the deck and into the top flutes of a steel deck.
The TX-25 recess provides excellent drivability and the drill-point design cuts a hole in the steel deck maintaining contact between the deck and the minor diameter of the fastener, increasing back-out resistance.
Delivery and StorageItems are delivered in boxes. Keep the materials in unopened packaging prior to use, reseal any damaged packing.
