The Chimsoc High Temperature Rubber Pipe Flashing (CS-CF11HTR) is designed for professionals and DIY enthusiasts installing chimneys, exhaust vents, or flues on pitched roofs. Its primary benefit is its high-grade silicone construction, which offers superior thermal resistance compared to standard EPDM flashings, making it perfect for wood-burning and multi-fuel stove setups. However, users should note that the 445mm x 445mm base requires careful planning for roof geometry to ensure a watertight seal during installation.

Yes, this flashing is suitable for various flue types including gas, wood-burning, and multi-fuel stoves.
It is generally not recommended to paint the silicone flashing as the expansion and contraction cycles of the material will likely cause the paint to crack.
The flashing is compatible with pipe diameters ranging from 160mm to 300mm.
No, you will need to purchase high-temperature, exterior-grade sealant and appropriate roofing screws separately.
While designed for pitched roofs, it can be installed on flat roofs provided the area is properly flashed and waterproofed to prevent pooling.
Ensure that the neutral-cure silicone sealant was applied continuously beneath the base and check if the fasteners are tightened sufficiently.
Gently warm the silicone base with a heat gun to increase flexibility, allowing it to better mold to the contours of the roof.
To install, first determine the correct diameter on the stepped cone and trim accordingly. Apply a bead of high-temperature-rated sealant to the underside of the base. Position the flashing over the pipe, pressing the base firmly against the roof material to eliminate gaps. Secure the base using roofing screws spaced at 25-30mm intervals around the perimeter. For maintenance, periodically inspect the seal for any signs of cracking or UV degradation, though the material is designed for a long service life. Keep the surface free of debris and leaf buildup to ensure optimal heat dissipation.
