The joint founders of First Glass Windows still maintain active roles within the company. Together they have over 60 years of experience in every aspect of the double-glazing industry.  Their objectives and plans for First Glass have always been for the company to be a cut above the rest, professional, unique in its approach to you the customer - something special…

When we set up First Glass Windows in 1990 our ideals were simple, customer care. 
We wanted to offer our customers a fresh, uncomplicated and non-pressured sales and installation service for PVCu windows, doors and conservatories which did away with all the negative things that the double glazing industry was known for.

Our blueprint for success is total commitment to good design, meticulous manufacturing superb installations and attention to detail at all times.

We really do care about our customers and their properties – a sentiment that is apparent in everything we undertake.  The quality of work speaks for itself, we don’t need to resort to high pressure sales techniques... we find that recommendations from our customers do the selling for us".
