Adhered roofing systems are suitable for both new and refurbishment applications. Sika-Trocal Type SGK fleece backed membrane is cold bonded to the substrate virtually eliminating penetration by mechanical fasteners.
Mechanically fastened systems are suitable for both new and refurbishment projects of any size. Sika-Trocal Type S membrane is mechanically fastened using the Sika-Trocal disc, a system that fastens both the insulation and the membrane, thus reducing the fasteners required for a project by 40-60% compared with other systems.
A ballasted (gravel/paved) roof will generally require a stronger supporting structure than that for the exposed membrane one, but will allow the roof to be used as a trafficked or leisure use area.
Green roofs are becoming increasingly a prerequisite for planning approval, either through biodiversity action plans, flood risk reduction as part of sustainable drainage systems or legislation
Green roofing systems are principally divided into three main categories: Biodiverse, Extensive, Intensive.
Sika-Trocal roofing systems can support a wide variety of Solar Thermal and Solar PV solutions to provide renewable energy sources.
