1NU-ROOF
- Supporting the roofing SMEs in the development
and use of a new generation of roofing materials
applicable with fault tolerant procedures,
reducing the use of petroleum-based products - (Grant Agreement No. 243616)
- Task 1.3 conceptual design presentation to wp2
meeting athens
TNO, Dapp
2Towards a conceptual design?
- Step 1.Specify the criteria (results from T1.1,
T1.2, T1.3)(technical, material, economical,
practical). - Step 2.Specify the materials by each
partnerSelect the most promising technologies
all partnersDefine of the roles of the partners. - Step 3.Agreement on the conceptual design and
material selection - Step 4.Research and development and integration.

16Conceptual design
Reflective Primer and Top Coating (NANOPHOS, NTUA)
3D Self Adhesive Textile matrix membrane (STFI
BORNER)
Encapsulation, and selection of functional agents
(TNO, NOTT)
DAPP/NTUA Do we need insulation material between
primer and substrate?
17Conceptual design Borner
topcoat (0.2 mm)
thin reinforcing fleece (0.5 mm, 50-150 g/m²)
impregnated with base coat. Base coat and/or
topcoat should include all functional additives
polymer bitumen based waterproofing layer ( 1,2
mm). Amounts of Bitumen and polymers should be
replaced, as far as possible, using materials
from renewable resources and/or from recycling
high performance reinforcement ( 1,6 mm, 200
300 g/m²) impregnated with polymer bitumen.
Amounts of (see above)
self adhesive bottom layer ( 1 mm), polymer
bitumen based. Amounts of (see above)
INSULATION
CONCRETE
18Conceptual design
- General remarks
- Non-woven materials is combined with a polymer.
Current on the market non-wovens is a non-woven
is combined with bitumen. - Glue is applied on the bottom to bind the
different rolls (is also existing).
19General questions with respect to conceptual
design
- Three steps approach (STFI, Borner)
- Standard product with reflective coating
- Reflective coating on a standard non-woven, with
encapsulated material - Napco spacer non-woven material, with topcoating
etc., with all possible encapsulated material
inbetween.
20General questions with respect to conceptual
design
- Questions with respect to conceptual design
- What is the function of the primer layer? (Think
about different substrates, wood and concrete) - What kind of seams are we making?
- What kind of glue are we going to use?
- Replacement of bitumen/non-woven by other polymer
system? Which system? Why? - Who is responsible for which element?
- What is our integration step?
21Scientific challenges to be solved
- To obtain a good conceptual design we need
- To answer many questions? Market, criteria,
application area, materials, norms,
responsibility, etc.. - Exchange information and ideas
- Input of all partners with respect to material
selections. - Combination of technical aspects. All partners
(particularly NTUA, NANOPHOS, BORNER, STFI, DAPP
and TNO)
22Scientific challenges to be solved and to think
about
- How can we introduce the top coat on the textile
membrane (after experimentation with textile
samples)? - How all these layers will match together?
- How can we introduce the capsules in the
non-woven? - What is the function of the primer? Adhesive
bonding? - How do we apply the top-coat on the non-woven?
- How do we join the roofing material together
(Seams and overlappings)? - What is the best replacement of bitumen?
23Material selection
- Encapsulant PCMs
- Non-wovens NAPCO
- Polymer Bitumen?
- Coatings ??
- Glue ??
- Substrate ??
24 25Roles during the Research Phase
- Input on material from all partners to section
2 material selection of D1.3 (doc) before 7th
of april. - TNO will combine this to a conceptual design for
13th of April as a basis for discussion - Partners foreseen
- NTUA, NANOPHOS, STFI, TNO, Borner, NOTT
26How we have proceeded
STEP1 Validate Criteria with partners by sending
over section 2 for comments
STEP2 Material selection (compromise between
Criteria and Budget / Time allowed). A first
discussion can be made in Athens
27Step1 a preliminary list of Measurable Criteria
needs has been reviewed by the partners
Translation into Measurable Criteria (t1.4).
Partners contribution needed
