INVERTED / GREEN ROOFS
Commonly know as an upside down roof for systems where the waterproofing membrane is protected by the insulation against foot traffic damage and thermal shocking. This system is also used beneath sedum mats for low maintenance green roofs.
The original “green” insulation. Styrodur 4000CS is an extruded polystyrene board with excellent insulation properties, high compressive strength, low water absorption and resistant to ageing and decay. Styrodur 4000CS is the compression-proof thermal insulation board with smooth surface and rebated on all four edges for load-bearing applications such as commercial floors, cold stores, car parks.
The original “green” insulation. Styrodur 5000CS is an extruded polystyrene board with excellent insulation properties, high compressive strength, low water absorption and resistant to ageing and decay. Styrodur 5000CS is the extremely compression-proof thermal insulation board with smooth surface and rebated on all four edges for applications with highest compressive strength requirements such as commercial floors, cold stores with mobile racking units, aircraft hangers etc.
A one-piece solution for insulation of upstands or parapets in roofs. Incorporating a 6mm exterior grade fibre cement board factory bonded to Styrofoam rigid insulation. Another product by FOAMtech that can be made to any thickness with no minimum requirement.
FOAMtech can fabricate Extruded Polystyrene (XPS) boards to suit your roof scheme in a range of compressive strengths depending on the project requirements. If you’re looking for someone to design your roof scheme we can also put you in touch with one of our partners that can do that for you so please drop us a line with your details.

The innovative universal thermal insulation board. Styrodur 3000CS is an extruded polystyrene board with a constant thermal conductivity of 0.033W/mK across the whole range of thicknesses available (30-240mm). As well as the excellent insulation properties Styrodur 3000CS has a high compressive strength, low water absorption and is resistant to ageing and decay. Styrodur 3000CS is the all-round thermal insulation board with smooth surface and rebated on all four edges for flooring, roofing and wall applications.
