Quality Assurance

Dreadnought Clay roof tiles conform to BS EN 1304:1998.

Dreadnought Tiles are Quality Assured to ISO 9001:2000

Relevant Test Information

Current freeze thaw test standards (test Method D) require plain clay tiles to withstand at least 100 freeze/thaw cycles.  This standard is soon to rise to 150 cycles (test Method E).  However, Dreadnought Tiles will withstand in excess of 400 freeze thaw cycles during testing.

We know from experience that Dreadnought Tiles last for in excess of 100 years.  In fact there are many cases where second hand Dreadnought Tiles sell for more than new tiles.

Poor performance in freeze/thaw test are an indication of the potential for the delamination of clay roof tiles over time, as moisture held within the pores of the tiles expands when frozen.
