Guardian Sun is a conservatory wall glazing solution, it is a high performance Low E glass which offers a 1.0 U value, combined with a low solar factor of just 43%. Guardian Sun is quite unique in its performance as it offers an exceptionally low reflection of 17% inside and 19% outside, which is rarely seen in thermally insulating Low E glass providing this level of performance.

Designed specifically for the residential window market and now for Conservatory wall glazing, Guardian Sun offers the ideal solution to help keep Conservatories cooler in summer and warmer in winter.
