Weather Resistance

Experience has shown that patent glazing used in pitches above 15° will produce excellent weather resistance. Pitches below 15° or where large volumes of water are likely, can be achieved successfully by means of a larger bottom overhang and additional sealing to the outer glazing bar cappings.

Our Skyline, Skyline Box and Rafterline glazing systems all include external pressure caps and are the most suitable for low pitches. Discharges from downpipes or other concentrations of water should not be allowed to flow over sloping patent glazing. Separate drainage gutters should always be provided.
