So authentic, you'll think it's timber.

Unbelievably, it's PVCu. We are the Approved Installer in the South Wales area for this breakthrough product, where the attention to detail and fit and finish are so exacting — you'll be convinced it's real timber.

Traditional design. Modern advantages. Hand-crafted from the finest materials, our selection of windows and doors offer outstanding energy savings, exceptional weather proofing and unequalled low maintenance not to be found anywhere in the industry. The incredibly realistic wooden finish on these products is deceiving - and rightly so. Internally you'll find the most advanced locking systems, silver-finished steel shoot bolts, both top and bottom.

Real craftsmanship. Every single bar is cut and fitted by hand. We know - like you do - that real quality, real craftsmanship, can only come from hand finished construction. It's what makes our windows and doors so exceptional.

Pioneering technology. Always interested in industrial-strength processes, we've introduced a bonding system first employed in the automotive industry. We now use this very same technique to fabricate each window and door by hand, delivering an unrivalled security advantage. In order to achieve the longevity and performance you demand, we also cure each unit for 24 hours in a state-of-the-art temperature controlled environment.

  • From standard casement windows through to large bespoke units, the team at Glasshouse were able to advise on and procure all our window requirements making it a smooth and straightforward process. Many thanks to you all!

  • We are very pleased with our replacement windows. Our original stained glass windows were incorporated into uPVC frames giving us the look of our old windows but the efficiency of new, energy-saving windows.

  • From salesman to the fitting team it has been a very pleasant experience. We have had a couple of minor adjustments made a month or so after installation. The speed and quality of the follow up was first class.

  • We are extremely pleased with our Norvys front door, it is extremely good quality and looks very good. We have had many compliments and would certainly recommend Glasshouse.
