A solid roof conservatory is perfect for any kind of conservatory build imaginable. Whether you’re looking for Georgian, Victorian or something more contemporary, no shape or size is impossible. While the roof itself may be solid, there is no need to sacrifice any light that a conventional conservatory would bring to the table, as these glass panels can be any shape and take the place of any of the standard aluminium or tiled roofing panels.

Stay Warm in Winter & Cool in Summer


We are delighted with our new conservatory and Guardian Warm Roof.  We now have a room we can use all year round. The installation was painless, the workmen cleared the site, removing old and installing new in 5 days.
I would highly recommend Thermseal Windows.

Great service from start to finish. From placing our order to having the windows and doors installed was only a few weeks. The installation was stress free and we were asked if we were happy with each stage as completed. The product looks great, very happy customers and would definitely use Thermseal again in the future.

Sandra Williams

Brilliant service. Had a small job ( replace guttering to front of house) to do that i needed sorting asap. Contacted Tony in the week and he quoted very quickly and reasonably. Agreed to what work I wanted done and he was there on the weekend sorting it. I enquired about another job that I thought needed doing. He was honest and open about it not needing doing yet. Any tradesman who only recommends on what works needing doing rather than chasing pounds is rare.
