a water-absorbing material that can trap
moisture inside a roofing system. This can
cause the roofing system to blister — which
can cause leakage and property damage.

layers of hot asphalt, and labor
to install
• Versatile… Can be used for
new roofs or reroofing
•H
elps Prevent Moisture Buildup… Keeps roof system drier
to help slow aging and protect
your investment
• F ewer Hassles… No space
needed to store cover board;
no dust or mess from cover
board either

Stratavent ® Perforated Venting Base
Sheet helps prevent moisture build-up!
This fiberglass-reinforced, granule-backed
venting base sheet replaces the traditional
bonding system for greater value and
excellent performance.
Here’s How It Works
Engineered Perforation Pattern...
Allows a single layer of mopping asphalt
to do two things at once: uniformly attach
through the perforations to the polyiso below
it—as well as attach to the ply sheet above it
Embedded Granules...
Top
Layer
Allow controlled venting of water vapor
to help prevent blisters and leaks
Simple Installation Means Fewer Hassles!
Just roll Stratavent ® Perforated Venting Base Sheet out dry...
