Pro-Flash Building Products Inc.

Booth C2241

We manufacture high quality and cost effective solutions that are designed to seal all penetrations within the building envelope such as pipe, electrical, vent pipe, windows/door sills etc.)

New for IBS 2023, will be the introduction of Flex-Sill window and door sill pan. Flex-Sill is an industry game-changer - a building technology that speeds up the build-cycle, increase quality, and helps ease labor shortages. As the only "drop-in-place" window/door flashing that comes on a 75' roll, it eliminates bulky sill pans and time-consuming adhesive application, making it the most cost-effective and simple solution on the market. Flex-Sill offers the full package including our pre-formed corners. No more ordering size-specific custom pans - Flex-Sill can be cut right to size and installed within seconds.

Our penetration seals simply slide over the pipe and provide a  'friction fit' to form a water tight seal protecting the building from moisture penetration caused by direct rain, snow, sleet etc.

Greenskins come in all sizes from 1/2" to 6".

Pro-Flash seals are equipped with score lines so that each unit can accommodate multiple pipe sizes. Pro-Flash seals are currently available in 1/8"-6" sizes. 


Mainline also manufactures award winning  innovative backwater valves designed to prevent sewer backup in homes/buildings. 3", 4" and 6" sizes.
