They pass the test!

Along with style, thermal efficiency and security, Thermotech’s replaceement doors undergo vigorous testing. This includes mimicking the life cycle of an average door, including opening and closing it over 50,000 times and putting them in a pressurised chamber to simulate winds of over 100mph.

The British Standards Institution rewarded all of our doors with a BS6375, otherwise known as one of their highest accolades and a definite seal of their approval. Tests such as theirs prove that Thermotech’s products will last for years to come and survive even the most extreme weather conditions (fingers crossed we won’t be hit by 100mph winds any time soon – although we do offer tiled roof replacements too!).
