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 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 layer

12
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
13
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

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)
23
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
