- Alumaguard All Weather (LT) Data Sheet

Alumaguard® is a premier vapor barrier, weather barrier, and UV barrier in an easy to install 'peel n stick' roll membrane. Alumaguard® is rubberized bitumen, foil faced membrane designed specifically to stick to insulation facings such as FSK and ASJ.

Alumaguard® has an excellent perm rating, very good puncture resistance, excellent sound attenuation properties (STC 18), superior bond strength, and like all our membranes, Alumaguard® heals itself if punctured. Alumaguard® carries a TEN YEAR WARRANTY! We have tested down to -35° F with no failures in either peel adhesion strength (after installation) or low temperature flexibility.

Recommended substrates are faced polyiso board (excellent R values), faced Styrofoam board, and faced fiberglass board, sheathing products with foil on both sides are also excellent substrates and insulators. (Tuff-R, R-Max, Celotex, Foamular).

To relieve pressure related stress we now sell a miniature one-way pressure release air valve, click here for more info.

If you are considering painting Alumaguard®, please read TECH UPDATE PAINTING ALUMAGUARD before making your decision.

For application below 50° F, Polyguard manufactures Low Temperature Activators to permit installation down to 25°F, extending the northern climates application season!

If you pre-apply Alumaguard®, to pipe insulation, the installation must be banded; Alumaguard® is not a mechanical fastener and the weight of the insulation and hot temperatures can cause failure if not banded. For more detailed information, please view the technical data sheet and installation instruction sheet for Alumaguard® and Alumaguard® Lite.
