We would absolutely recommend the WARMroof Hybrid. We now sit in this room almost all of the time, relaxing and enjoying the view of our garden. The whole process ran like clockwork and overall, we are very happy with our newly refurbished conservatory.
The best part of our new conservatory is that we can sit and relax in a warm room yet can still see the blue sky with the clouds rolling past. The Hybrid has allowed us to retain the amount of light that floods into the conservatory, yet it’s now much more thermally efficient, which we noticed instantly, providing us with a room we can use all year round.
