Research for SME Associations (SME-AGs)

Funding SchemeIn these kinds of Projects, the full ownership of all project results (called “foreground”) and Intellectual Property Rights (IPRs) is given to SME associations

SME associations have the possibility to find tailor-made solutions to organise the ownership of project results and its dissemination and use in a way that takes into account the needs, interests and capabilities of the SME-AGs and their members, of the Other enterprises and end-users involved in the project as well as the RTD performers

The Need for European SMEs

• One of the most important and costly operation in the construction and maintenance of a building is the waterproofing of the flat-roof

• Roof insulation is the most critical component and first responder in terms of energy efficiency

• The landfill waste from roofing currently represents almost 4% of the total volume of solid wastes1

• Current bitumen based materials used for waterproofing are applied with heat, locally melting the edges to create a continuous impermeable layer1 Oak Ridge National Lab, Buildings Envelope Research Center

13

• The current installation procedure can lead to error and leaks are extremely difficult (if not impossible) to detect prior them causing damage to the roof structure

• Standardization, the cross pollination of best-practices, and the ability of innovative producers to bring products to the market are extremely problematic in the roofing industry

• The value chain of roof waterproofing is almost totally based on the experience and skills of operators. However, producers can only apply for a new standard or ETA once the product has captured enough market share through pilot projects and demonstrate market acceptance

The Need for European SMEs

14

• A popular material to flat roof covering is the bitumen-based membrane. Drawbacks are:

• Traditional membranes heat up the roof temperature in summer and reduce life time, due to the dark colour of bitumen. Reflective membranes do not last more than 5 years since are mainly coated on site

• Need constant maintenance to prevent dust, corrosion and abrasion

• Have impact on workers’ health and are dependent on operators 'skills with often laying failures, due to torch-on utilization

• Poorly recyclable, needing special procedures for land-filling, because they are oil based

NU-ROOF Project – the problem

These materials will be tested in different environmental and weather conditions and combined to improve waterproofness

DESCRIPTION (Leader: TNO)

19

An innovative approach is proposed:

• Polyester-reinforced-based top layer, impregnated with acrylate or modified rubber bitumen dispersion laminated directly in the production process

• Light coloured, highly NIR and visible light reflective top coating• Smooth, non-porous and non-sticky top coat surface at high

temperature• A radically new non woven textile able to absorb the coating and

the other waterproofing elements in the top layer• The experimental use of Phase Change Materials in the base layer of

the membrane to test how much heat is stored and improve the overall roof thermal capacity

• The experimental use of a cold process using a Bitumen Based Emulsion to reduce the embodied energy of the compound

• Up to 33% of recycled components• Single Ply system and Self Adhesive Application

• A new range of products based on bitumen based non-woven textile technologies with energy saving properties, low embodied energy and partially based on recycled and sustainable components (45 -60 %)

• Reflectance up to 0,8 with ageing decrease below 5% in three years, that translates to an energy saving on cooling depending on climate. The temperature reduction at the back side of the metal panels was about 15 °C and at the back side of concrete about 3,5 °C.

• Follows all European Standards on waterproofness, mechanical resistance, VOC free, fire resistance

• Outstanding robustness

• Easy to apply (no need for on site after treatment)

Main Deliverables/Outcome

The project will characterize, test and integrate state of the art advanced roofing technologies (non woven membranes, coatings, encapsulated active agents such as, natural waxes and oils for waterproofness).The results will be integrated into a knowledge base platform where characteristics of the materials tested in different conditions will be collected. The platform will include a Customization Support Tool, able to support the SMEs of the roofing /construction sector in the selection of the best combination of products and application technique, according to the climate, location, type of building or structure, type of intervention (retrofitting or new construction), etc.An important outcome of the project will consist of guidelines to application methods in which there will be the definition of good practices for the future
