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

Research for SME Associations (SME-AGs)Funding
Scheme
In 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

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 layer

13
The Need for European SMEs

• 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

14
NU-ROOF Project the problem

• 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 concept

• 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 results

• 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
