Impermeable in all weathers, Crossgrip TPO (thermoplastic polyolefin) is highly specialised matting system for flat roofs, gantries and high level walkways, which provides continuous safe access to essential roof top services for maintenance. When laid flat, it will remain stable in winds up to 60 mph/96 km/h*, however if wind speeds of over 60mph are probable, Plastex recommends securing the matting system by welding connecting loops into the vinyl membrane.
Crossgrip TPO is constructed from non-porous TPO in a unique design of special cross directional top ribs with an embossed surface to give permanent slip resistance and a surer underfoot grip in a wide range of high level applications.
The effective combination of an open grid format and 12 mm (1/2") above ground height enables self-draining and makes Crossgrip TPO at its most efficient wherever water collects or puddles may occur.
Once installed, Crossgrip TPO will only require minimal periodic maintenance, such as cleaning and visual inspection for damage or movement, and will remain effective for the life of the roof covering below. Compatible with TPO, EPDM, PVC and modified bitumen roofs, the product additionally gives continuous protection to roofing membranes from damaging weather, pedestrian traffic, tools and machinery.
Another major advantage is that Crossgrip TPO is quick and easy to install. The flexibility of the product ensures that it will contour to uneven surfaces or imperfections in the roof structure, which are common where new membrane systems are laid over old ones.
Crossgrip TPO comes in white, and is supplied as standard in rolls of 10 m (33') x 75 cm (30").
*Loose laid it is effective for winds up to 60mph (96 km/h). In Laboratory conditions on a flat surface at The University Of Hertforshire, School of Aerospace, Automotive & Design Engineering:
PVC Grid: stable in wind speeds up to 94mph (150 km/h);
TPO Grid: stable in wind speeds up to 88mph (142km/h).
