Patterned Glass!!

We're excited to announce the addition of new types of patterned glass to our product range. Our etched Victorian Gothic inspired patterns are available in a range of ten designs.

Ranging from bold Amber Gothic to the pointedly minimalist Star, we're sure to have something that catches your eye.

Please visit the "Patterned Glass" section of our website for more information, and to see the whole range of patterns we offer.


We're thrilled to share a lovely piece of feedback from one of our satisfied customers:

"I purchased my glass splashback from Treforest glass; they also fitted it for me. I am over the moon with the end result and can highly recommend them. They are a brilliant firm to deal with. My glass splashback is the finishing touch to my kitchen and is so easy to clean. I have had so many compliments off people who absolutely love it. So thank you Treforest Glass." - Mrs Preece



Another successful secondary glazing project completed by our expert glazing services team:

A customer asked us to install Secondary Glazing to their home in the Brecon Beacons. They wanted us to help retain the original timber windows which were in excellent condition.

Our slim secondary glazing provided them with a reduction in heating costs, a warmer home and reduced internal condensation; maintaining the traditional 'look' to the facade of their home.

At Treforest Glass we are always happy to match your exact needs and specifications. We think you'll agree from these before and after pics... Another job well done!
