The Chimsoc High Temperature Pipe Flashing is designed for professional roofers and homeowners installing high-heat ventilation systems, such as wood-burning stoves or industrial exhaust flues. Its primary benefit is its high-grade silicone construction, which offers superior thermal resilience over standard rubber alternatives, though users should ensure their pipe diameter falls within the 152mm to 279mm range before purchase. This flashing combines extreme temperature tolerance with a flexible base, ensuring a durable, weather-tight seal on roof pitches up to 40 degrees.

Yes, it is suitable for gas flues, provided the operating temperature remains within the specified range of -50C to +225C.
Yes, it is effective on roof pitches ranging from 0 degrees (flat) to 40 degrees.
The silicone is UV-stabilized to maintain its black appearance and structural properties even after prolonged sun exposure.
You typically need a utility knife for trimming, a sealant gun for the adhesive, and a drill or screwdriver for securing the base fasteners.
It is not recommended to paint the silicone flashing, as the expansion and contraction of the rubber can cause paint to crack and flake off.
No, the flashing is provided as the rubber component. You will need to purchase compatible fasteners and high-temperature roof sealant separately.
Ensure that high-temperature sealant was applied correctly under the flashing base and that all fasteners are tightened securely.
Verify that your pipe diameter is within the 152-279mm range and use a stainless steel clamping band to secure the neck of the flashing.
To install, first ensure the roof surface is clean and dry. Slip the flashing over the pipe and press the base down to conform to the roof's profile. Use an appropriate high-temperature rated roof sealant under the base before fastening it down with screws or rivets to ensure a watertight bond. Periodically inspect the rubber for any signs of cracking or UV damage during annual roof maintenance checks. If the flashing is covered in debris, gently clean it with a soft brush and water; avoid using abrasive chemicals that could compromise the silicone material.
