SpectraRoof® TPE Roof Engineering combines the best from the worlds of experience of elastomers and thermoplasts

The SpectraRoof® TPE Roof Engineering concept for single-ply synthetic roofing systems has been developed within the IKO Group.  
Besides SpectraPlan® roofing sheets, this concept comprises components such as thermal insulation, fixing devices and vapour control layers plus also all accessories for detail work. Project sup port in the form of advice, inspections, technical calculations/specifications and work supervision form an integral part of the concept.

SpectraPlan® roofing sheets have exceptional product properties: 

High resistance to ageing   

SpectraPlan® roofing sheets hardly degrade under UV exposure. The action of ozone does not cause surface erosion. Standing water does not have any detrimental or leaching effects. This ensures a very long life expectancy for SpectraPlan® TPE roofing systems.

Reliable and secure seam welding 

The SpectraPlan® TPE polymer has a very broad “thermal welding range”, which minimises its operational sensitivity. This is determined by the excellent flow behaviour of the TPE polymer. SpectraPlan® roofing sheets also have high internal cohesion. The use of identical TPE polymers at the top and bottom side of the roofing sheet, combined with the excellent flow behaviour, produces a homogeneous and reliable weld, which is stronger than the roofing sheet itself. The TPE polymer does not absorb water, thus ensuring a high quality heat-welded joint, even after ageing.  

Non-capillary construction  

The excellent flow behaviour of the polymer ensures perfect coating of the polyester fibres of the carrier so that no capillaries are created. SpectraPlan® TPE roofing sheets are reinforced with fibres that do not absorb moisture. Additional security is provided by the homogeneous self-edge, produced during manufacture.  

Chemical resistance and compatibility 

The high degree of purity in the TPE polymers, their amorphous structure and the absence of volatile substances lead to exceptionally high chemical resistance. SpectraPlan® TPE roofing sheets are resistant to many organic and inorganic substances and solvents. SpectraPlan® TPE roofing sheets are also compatible with bitumen and they can be directly applied to (existing) bituminous coverings and polystyrene (EPS/XPS), without a separation layer being required.
