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.
