Stock a wide variety of patent aluminium roof glazing bars held by our sister company pennycook patent glazing co. Figure 10 sloped glazing built in 1980 s investigated after collapse. Established in 1880 ppg continues to be recognised as a leading designer and supplier of patent glazing systems offering innovative design solutions to a wide variety of overhead glazing requirements. Here are a few more things to think about in relation to roof pitch and specifying skylights.

Framing supporting sloped glazing and skylights shall be designed to resist the tributary roof loads in chapter 16. At eaves the bottom purlin is often stiffer than the upper one causing water ponding. Aluminium roof glazing bars. Skylights set at an angle of less than 45 degrees 0 79 rad from the horizontal plane shall be mounted at least 4 inches 102 mm above the plane of the roof on a curb constructed as required for the frame.

Sloped glazing is a system of exterior cladding which is attached to the main force resisting system structure of a building roof or sloped façade and usually supported by an elevated curb. The sloped glazing system is designed to withstand uniform gravity loads such as dead load wind load and snow load as well as concentrated live and impact loads and transfer them to the structure. Other considerations for roof pitch and specification. Deflection there is a level of flex that will occur in all glazing and it can be particularly apparent in overhead installations.
