Marco's Flex-O-Vent™ Universal
Venting Material vents, protects
and lasts like no other. While
polyurethane products constantly
expand (as they soak up water)
and contract (as they dry out)
causing them to disintegrate and
fail, Flex-O-Vent offers 40 years
of Weather-Tite performance.
Its specially formulated polyester,
manufactured from recycled material,
prevents moisture absorption and
holds together to help keep out pests.
Flex-O-Vent is also extremely durable,
flame-resistant, clog-resistant, and
tear-resistant.
