Sandwich panel SP2D E-PIR

Sandwich panel SP2D E-PIR is available in thicknesses 60 - 120 mm.

It is a perfect solution for most buildings and structures, combining high quality with very good technical properties

The core of this sandwich panel is made of rigid, HCFC-free, self-extinguishing and sustainable polyisocyanurate foam (PIR). Its excellent thermal insulation properties enable the decrease of panel thickness which transfers directly to lower transportation and assembly costs, as well as significant savings of building's life cycle costs.

    Coatings and colours


    Facing Coating Corrosivity category UV resistance  Colours
    External GreenCoat HIARC MAX C4 Ruv4  RAL7035, RAL9006, RAL9007
    External  Polyester C3 Ruv2-3  RAL1015, RAL3013, RAL5005, RAL6011, RAL7015, RAL7016, RAL7035, RAL9002, RAL9006, RAL9007, RAL9010
    Internal Polyester C3 RAL9002, RAL9010

    UV resistance describes how well the coating is able to keep its original colour and gloss levels in accordance with EN10169. The higher the class, the better the resistance.

    Corrosivity categories describe the outdoor climate conditions in accordance with EN12944. The higher the category, the more corrosive environment.
