For Canadian synthetic roofing expert Polysand, durability is the watchword. Its new innovative SyntheticSlate roofing tile — a composite material made from virgin polymers and recycled filler — can withstand extreme temperatures (from -60°C to 80°C) and offers high UV protection to prevent cracking and fading.

The slate (available in onyx and ash grey) is even resistant to weed and moss growth due to its lack of open pores. And at only one kilogram per tile, SyntheticSlate is five times lighter than a slab of natural slate with the same dimensions. With an organic edge design, standard tiles are 55.8 centimetres long and 30.4 centimetres wide — with a thickness of only 1.2 centimetres.
