SILVER parking EPS 100    EPS-EN 13163-T(1)-L(2)-W(2)-S(2)-P(5)-BS150-CS(10)100-DS(N)2-DS(70,-)2-DLT(1)5-TR150

Those are white or “spotted” boards produced by foaming polystyrene and intended for thermal insulation of floor, roofs, flat roofs and car parks. The boards may be produced with flat or milled edges enabling proper fitting. The boards are manufactured in standard dimensions: 1000 mm long, 500 mm wide, 10 mm thick, and then every 10 mm. A compressive creep deformation of 2% or less, when subjected to a permanent compressive stress of 30 kPa (3000 kG/m2).


Polystyrene subjected to voluntary certification and recommendation procedure at Building Research Institute (Polish: ITB), not resulting from the system of assessment and verification of performance constancy.

    The EPS boards should be applied in accordance with the manufacturer’s instructions, RTQ ITB 1260/2013 Technical and Quality Recommendations and  guidelines contained in a construction design. The basic guidelines for laying thermal insulation of floors and ceilings are as follows: make sure that the screed is flat and dry, otherwise level it out. The floors on the ground require a damp proofing barrier (in form of tar paper, PE film, bituminous and water-based sealants). Apply a separating layer of PE film in intermediate floors. Where the floor meets the wall, use an expansion jointing tape. Start laying the boards in the corner and place the first row of boards from the wall by pushing them against the expansion jointing tape. Subsequent rows should be laid with staggered  joints, avoiding crossing board joints. When all insulation is in place (can be in two or more layers), spread at least 0.2 mm thick PE film, to protect the boards against moisture and penetration of the screed in the spaces between the EPS boards. Where water-based underfloor heating is used, install the heating cables with suitable clips on the boards on which the PE film has already been spread. Please note that the thickness of the screed needs to be increased by the outer diameter of the underfloor heating cables.


    Do not use the EPS boards in direct contact with the substances having destructive effect on polystyrene, such as organic solvents (acetone, benzene, nitro), etc.
