How much do you overlap polycarbonate sheets? It is best to use a ladder or other suitable access equipment when necessary. For this reason, it’s important to make sure the area below the polycarbonate roofing is open and clear and that any individuals are aware of the potential danger before attempting to walk on any panels. While walking on polycarbonate panels can cause damage to the structure, it can also be hazardous to the person attempting to walk on it due to the risk of slipping and falling. This makes it ideal for many uses, such as conservatories and skylights, but its construction is not suitable for walking on.

Polycarbonate roofing is a type of plastic material that is durable but also very lightweight. No, you cannot walk on polycarbonate roofing. Ultimately, the angle of the roof should be based on the climate and the purpose of the roof. Generally, for mixed climates or climates with lower amounts of snowfall, a roof that is pitched between 7 to 22 degrees is recommended, while in regions with frequent snowfall, a roof should be pitched between 15 to 30 degrees. When determining the angle for a polycarbonate roof, there are a few general guidelines that can be followed. Additionally, if the roof is intended to help provide direct lighting for an interior area, a shallower angle is recommended for maximum light exposure. In hot and sunny climates, a shallower angle is typically recommended in order to maximize shade and minimize heat transfer. For example, in areas that experience a lot of snowfall, the roof should be at a steeper angle to help with snow shedding. The angle at which the polycarbonate roof should be installed largely depends on the local climate. What angle should a polycarbonate roof be? As such, installing purlins when roofing with polycarbonate is highly recommended. When installing a polycarbonate roof, it may be necessary to use purlins to ensure that the roof is properly supported and has the necessary strength to carry the load of both the roof and the snow load.Īdditionally, purlins may help to reduce thermal bridging in the roofing system. They are used to provide additional support for the structure and to distribute the weight of the roof. Purlins are horizontal members (also known as framing) that span between the rafters of your roof structure.

Yes, purlins are typically needed when installing a polycarbonate roof. Do you need purlins for polycarbonate roof? Ultimately, the ideal purlin spacing for any given application should be based on an assessment of the design and load requirements according to the manufacturer’s installation instructions. Additionally, for roofing applications involving heavier loads or extra weight due to snow and heavy rain, it is beneficial to opt for a slightly narrower gap of 1 foot or less. However, the exact distancing required can vary depending on the size of the sheets and the application for which it is being used.įor instance, for larger sheet sizes it is often wise to leave a gap of 3 feet or more. When installing a polycarbonate roof with purlins, the general rule is to use 1/2″ thick purlins no more than 2 feet apart.
