We supply two main types of glazing for our conservatory roofs. Both are excellent at their job and it is largly the choice of our customers as to which are supplied with each conservatory.
Polycarbonate is ideal for the DIY'er as it is lightweight, very strong and has superb insulating properties. Easy to handle and install. With a wide range of colours and solar control features, there is plenty of choice. ( Solar control is ideal on a South facing conservatory as it reflects the suns rays back into the air away from the interior of the conservatory ).
Glass is also available in a range of types - all toughened and with various finishes from clear to blue active or grey antisun. These have the same kind of properties as solar control polycarbonate. The downside of a glass roof can be the extra cost, and the weight which makes it more awkward to fit and requires more labour.
However, if you are in your conservatory during a hail storm, you will appreciate the extra quietness of a glass roof over polycarbonate!
