Radbar Flexible Top Hat 110mm and 160mm - Hydrocarbon
Flexible Top Hats designed for use with Flexible Hydrocarbon Membranes to provide protection. Part of a Radbar Hydrocarbon Gas System.
Hydrocarbon Top Hats
Radbar Flexible Top Hats are designed to provide a highly effective seal around service pipes in a hydrocarbon gas membrane system. Where pipework needs to penetrate a flexible hydrocarbon membrane, you need to use these flexible Top Hats. We stock both 110mm and 160mm diameters to match your pipework requirements.
The Top Hats have been manufactured from specific polymers so that they are not impacted by the presence of Hydrocarbon. As part of a hydrocarbon gas system, they protect properties and occupants from harmful ground gases and hydrocarbons.
How to install a Flexible Top Hat
Installing a flexible hydrocarbon top hat is a simple process. Start by cutting out a hole in the membrane as close as you can to the pipe. The tapes are then placed in position ready to accept the top hat (please refer to the installtion guide available in the 'Downloads' tab above). Once the pipe is in position, you should push the Radon Top Hat over the pipe.
Important note: avoid pipe entry points at membrane joints.
It’s essential that gas-tight seals should be formed around all service entry points. The base of the pre-formed Top Hat unit should be sealed to the Hydrocarbon Barrier Membrane with RADBAR Hydrocarbon Double Sided Tape and RADBAR Hydrocarbon Single Sided Tape. You can also use the Radbar Gas Sealant Cartridge for all service penetrations.
