2. 2 Research for SME Associations (SME-AGs) Funding Scheme The funding scheme Research for SME Associations (formerly Collective Research) aims at strengthening the innovation capacities of SMEs to develop new products and markets through the acquisition of new knowledge from those institutions best suited to carry out research SMEs Help in developing new products and markets RTD Performers

3. 3 Research for SME Associations (SME-AGs) Funding Scheme SME Associations and their members are the direct beneficiaries of the project. SME Associations invest in the RTD project and subcontract most of the research and demonstration activities to RTD Performers and receive in return the technological know-how they need SME-AGs RTD Performers Technological know how Subcontract research & development activities

4. 4 Research for SME Associations (SME-AGs) Funding Scheme A project typically requires a mix of different activities: 1. Research and Technological Development Activities (RTD) 2. Demonstration Activities (DEMO) 3. Other Activities (OTHER) 4. Management Activities (MANAG)

12. 12 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 wastes 1 Current bitumen based materials used for waterproofing are applied with heat, locally melting the edges to create a continuous impermeable layer 1 Oak Ridge National Lab, Buildings Envelope Research Center

13. 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. 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

15. 15 These materials will be tested in different environmental and weather conditions and combined to improve waterproofness Two offsetting bitumous-based membranes joined by flame Single-layer, self-adhesive, high-performance membrane EXISTING State of the Art NUROOF Primer/Sealer Example of existing SoA and NU-ROOF technology NU-ROOF Enabling Technologies

19. 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 NU-ROOF Project – the concept

23. 23 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) NU-ROOF Project – results

24. 24 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
