Besides allowing the venting of moisture which is critical for the roof system's integrity and longevity, the application of STRATAVENT^® Base Sheets provides several other important advantages.

For decks insulated with GAFTEMP^® Isotherm, the roof membrane can not be solidly mopped to the insulation. When STRATAVENT^® Perforated is installed properly, it can be used as the base sheet.

Because STRATAVENT^® Perforated Base Sheet can be applied directly on top of isocyanurate roof insulation, you eliminate the need for an overlay board as well as the time and labor to apply it.

Since it's a heavy product, the STRATAVENT^® Sheet lays down flat.

STRATAVENT^® Perforated provides such a consistent, uniform spot attachment that it is wind uplift-resistant and has an FM rating up to 1-180.

STRATAVENT^® Perforated Membrane is fire resistant. So it's approved for UL Class A rated roof assemblies.

And STRATAVENT^® Perforated meets requirements for application in all climates.
