Aztec ProFlash Roof Collar 50-170mm

The Aztec ProFlash roof collar is the large size in the range, sealing pipes from 50 to 170mm where they come through the roof. It is built for flues, large vents and bigger exhausts, and the wide flexible base with a sticky back dresses down over the roof profile to form a watertight seal. The larger base area spreads the seal over a bigger footprint, which keeps the joint stable on profiled roofs.

Installation

Slide the collar over the flue or pipe and press the base onto the roof. The sticky back holds it in place, and the flexible body dresses down over the tiles or sheets with hand pressure or a soft hammer. Trim the base with scissors where it needs to clear an obstacle, then seal the top edge against the pipe. The collar installs without heat, mastic or fasteners.

Applications

• Flues and chimney pipes through metal and tile roofs
• Large exhaust and ventilation penetrations
• Solar and plumbing conduits up to 170mm
• Roofs where a wide lead-free pipe seal is needed

Frequently Asked Questions

What sizes does this collar cover?

It covers pipes from 50 to 170mm, which makes it the largest ProFlash collar. It suits flues, big vents and exhausts where the standard collar is too small.

How does the wide base help on a profiled roof?

The larger base spreads the seal over a bigger area of the roof profile, so the collar sits stable over the corrugations and dresses down to follow them. That keeps the seal tight on sheet and tile roofs.

Is it suitable for a flue?

Yes, for a standard flue within the 50 to 170mm range. If the flue carries extreme heat, check the temperature exposure against the material, and use a high-temperature metal flashing for a flue that runs hot.

Does it need sealant as well?

No. The sticky back forms the seal on its own. You can add a bead of sealant around the top edge against the pipe as extra insurance, but it is not required for a watertight fit.
