Python™ Single-Layer Vent
Brand: Marco IndustriesOur recycled polyester, single-layer ridge vent can be used under ridge caps, ridge shingles and as a fascia vent to keep attics cooler in summer and dryer in winter.
Ideal for all roof applications, Python helps reduce utility costs, and its non-wicking performance helps keep out insects, dust and moisture. Miami-Dade County Approved*, Python is backed by a limited lifetime warranty.
Python is not fabric covered and comes in a coil. It’s a strong, durable, modified polyester and can be used under ridge caps, under ridge shingles and as a fascia vent with all roof applications.
Python’s non-woven, non-wicking, fiber-based matting has no external baffle, which greatly reduces dirt and snow trapping.
When used as a fascia vent, Python helps eliminate mold build-up. As a ridge vent, it helps keep out insects, dust and moisture.
This versatile product allows fresh air to be drawn into the attic and hot or stale air from inside to be drawn out through the ridge vent, reducing utility costs year-round.
