Im sure we used these on our house

Ill try to find some pics out, but the front of the house which was 19 ft across by around maybe 10 ft high, cost me £1500. That was about 2.5 years ago.
If you crack it, or chip it, they come out and repair it for free, I think the guarantee was 10 years or something, and the stuff they used i belive was called ecotech or ecotex. Really cant remember now
