What is the pocket of the playground?
pipes and other roof penetrations may endanger the integrity and weather resistance of the entire roof structure. These penetrations allow moisture to penetrate the roof insulation and framed under the roof tiles, which can lead to rot, mold or other problems. In order to prevent the roof structure from preventing the roof structure, the builders install metal flashing and counterweight along the penetration of the roof and the transition areas. While traditional metal shoes or pipe sleeves can be used to protect standard objects, irregular objects may require a special flashing known as the pitch pocket. Made of sheet metal, such as aluminum or steel, pockets fit around many different types of roof penetrations to keep water out and help protect the roof structure. The flanges on the base of the pocket pitch are attached to the upper part of the roof structure, while the vertical parts are suitable around pipes or other objets on the roof. Usually these devices are captured or open along one corner for fast and easy installation. InstallerThe workers then align the open seam using built -in connectors or grooves. Some pocket pocket models may require welding or special adhesive, while others can be damaged using a interconnected seam.
Originally coal or tar spacing was used to seal these accessories on the roof deck, a place where the name of the pitch gets. Today, the installer can pour hot asphalt or grouting into the top of the pitch pocket to create a tight seal. By filling all the gaps between the base of the pockets and the roof of the asphalt, it prevents water leakage to the roof. Some pocket pockets come with special seals rather than injection or asphalt for easy installation. Builders should be careful not to find a compatible material that does not hurt the existing roof when looking for ways to sea the playground.
pitch pockets should not be used to support or attachthe invitation of pipes or other objects to the roof. Also, they are not designed to avoid moving or moving these objects. All pipes and other items should be properly secured before installing the playground to reduce the risk of roof damage.
Pitch pockets are often paired with a storm collar or other form of a counterattack to further reduce the risk of leaks. Storm the collar fits firmly around the pipe diameter and then stretches on the base to cover the upper part of the pocket of the pitch. Storm collar should be long enough to completely cover the edge of the pocket pitch and wide enough to allow all rain or moisture to fall well on the roof out of flashing.
