HeavyGUARD® – Protected Membrane Roof Panels

HeavyGUARD® applications include: Low-slope Protected Membrane Roofs.

By simply reversing conventional design and placing the insulation above the membrane rather than below, the cause of many life shortening roofing problems can be eliminated.  This unconventional arrangement of roofing material – roof deck, roof membrane, LightGUARD or HeavyGUARD ballasted roof insulation panels – is commonly referred to as the “upside-down” roof system or Protected Membrane Roofing (PMR) system.

In all areas of the building envelope, the moisture barrier is placed on the warm side of the insulation. With one exception – a conventional roof system.  In a T. Clear PMR system the insulation is placed above the waterproof membrane to protect it from the harsh rooftop environment.

HeavyGUARD panels provide both insulation and heavyweight ballast in one easy step for Protected Membrane Roof Systems. Panels are composed of 2 or 3 inches of Dow Styrofoam with a 15/16-inch latex-modified concrete topping on a 2’x4′ tongue-and-groove panel, weighing 11 lb. per square foot per panel.  HeavyGUARD panels are perfect for rooftop gardens and light-traffic decks.

As with any cement based product, color variation, efflorescence, and/or hairline cracking of the cementitious facing may occur.  The phenomenon will not affect the performance of the HeavyGUARD panels and will not affect the warranty.  If uniform or matching coloring is required, a quality latex masonry coating must be applied.
