Meet CoolGlass

We pride ourselves on being an honest, friendly and professional family company. 

We live and work from the heart of the Lincolnshire countryside in the Ancholme Valley, on the edge of the beautiful Lincolnshire Wolds. Our location means we can visit customers throughout northern and central England. However, we have done installations all over the country and can travel nationally when required.



Meet our Founder

Mark Bletcher trained in automotive and architectural window films and has been supplying and installing them since 2004.  He cut his teeth providing tinted windows for local car dealers, but very quickly developed his expertise for architectural solutions. 

He then gained experience in Australia, where window films are almost as commonplace as windows themselves, applying them to large glass areas and facades that often caused homes and businesses to overheat.

Mark Bletcher
