| Download here the outline spec DOC (24,5 kb) |
The thermal insulation will be realised by a board of rigid polyurethane foam (EUROFLOOR) with a core volume weight of ± 30 kg/m³.
Reaction to fire: class A1 according to RD 19/12/1997, class 1 according to BS 476 part 7 and Euroclass F according to EN 13501-1.
The boards will be faced on either side with a mat grey gastight multi-layered complex of kraft paper and metal foils.
The boards have a technical approval and CEN Keymark. The boards will be subject to a permanent quality control done by an acknowledged institute.
The pressure resistance with 10 % deformation: > 120 kPa (1,2 kg/cm²).
The production of the insulation boards is certified according to the ISO 9001:2008 standards.
The declared thermal conductivity coefficient λD = 0,023 W/mK.
The dimensions of the boards are 1200 x 2500 mm.
The boards have to be installed on an even and smooth surface in order to avoid thermal bridges and deformations.
They will be installed on a polyethylene foil with well-butted joints. The overlaps between the several polyethylene foils need to be 10 cm at least.
The surfaces that will be exposed to pressure have to be covered with a pressure spreading material in order to avoid damages.
The following dimensions have to be used:
