Foamboard

Foamboard 2000 D - 2500 D - 3000 D - 3500 D is an extruded polystyrene boards with skin surface. They are used on water proofing membrane for the thermal insulation of flat roofs.
 

Application Area

• The membrane (bituminous, pvc, tpo, ect.) forming water and vapour proofing is rolled out on existing levelling concrete.
• Foamboard boards of 2000 D - 2500 D - 3000 D - 3500 D are laid together without applying adhesive so that the joints are adjusted.
• Filter element and cover that serves as seperator felt are laid on the boards.
• For the inaccessible flat roofs, a layer of washed round light-coloured gravel is placed on top of the separator cover in order to put weight and to reflect sun rays.
• For the accessible flat roofs, precast tiles (concrete, wood, etc.) are placed resting on plastic wedges.
• If desired, floor coverings applied with sand or grout can be used as well.
• For the garden flat roofs, the layers including gravel are applied like the inaccessible flat roof.
• Filter element and plant soil are laid out on the gravel to finish off the process.
