Black 1/2 Round Guttering 4m Length

Rainwater system is co-extruded with a white interior and a range of exterior colours – Freefoam’s new innovative solution to the blems associated with rapid heat absorption and expansion of gutters. Widely published test results show that while a white surface exposed to sunshine can absorb heat and attain a surface temperature 10ºC or more over the air temperature, dark surfaces can rise a further 30-40ºC and exceed the softening point of the PVC. On large capacity gutters with a large surface area facing the sun, this can be a particular blem. While the interior willbe exposed to sunlight as normal, its absorption of heat from thesun and subsequent expansion along its width and length will besignifi cantly reduced, thus dramatically decreasing the bability of any associated blems.
