STRATAVENT® Perforated Venting Base Sheet

Why GAFGLAS® STRATAVENT® Perforated Venting Base Sheets?

GAFGLAS® STRATAVENT® Perforated Venting Base Sheets are unique in the industry: the patented perforated design allows mopping asphalt to flow through to the substrate as the next ply of the roof system is installed. The flow-through asphalt uniformly bonds the GAFGLAS® STRATAVENT® Perforated Venting Base Sheet and the subsequent roof system to the substrate. It also offers excellent wind uplift-resistance (FMRC Approved up to Class 1-345 — See FM Approval Guide for details). 

GAFGLAS® STRATAVENT® Perforated Venting Base Sheets are fire resistant— for use in UL, ULC Class A rated assemblies — and system guarantees are available for up to 20 years.

Uses

GAFGLAS® STRATAVENT® Perforated Venting Base Sheets are designed to be used in various GAFGLAS® built-up and RUBEROID® modified bitumen roofing systems, including certain existing old roof surfaces and isocyanurate foams. They can be mechanically attached to wood, structural wood fiber, poured gypsum, and lightweight insulating concrete decks.
