FlashGard Thru-Wall Flashing

Firestone’s FlashGard Thru-Wall Flashing is a high performance, flexible membrane alternative for protecting masonry walls from water damage. It is based on EPDM (ethylene propylene diene terpolymer) synthetic rubber — an elastomeric rubber membrane with a tradition of superior performance in harsh environments including commercial roofing and environmental containment.

Firestone’s flexible 40 mil (1.02 mm) FlashGard Membrane forms a barrier to moisture ingress in cavity wall construction by directing water to a building’s exterior.

Excellent Physical Properties

FlashGard is a tough, resilient membrane that remains flexible even after aging. It exhibits excellent uniaxial and multiaxial tensile and hydrostatic features, enabling it to withstand typical stresses caused by point loading conditions in a masonry application while maintaining membrane integrity. Outstanding expansion and contraction characteristics contribute to FlashGard’s success in the dynamic building environment.

Extreme Durability

FlashGard is highly resistant to corrosion, abrasion and wear even when exposed to caustic materials present in, and used with, concrete and masonry. Additionally, FlashGard’s high modulus, excellent thermal and dimensional stability along with its superior resistance to weathering and ultraviolet radiation make it ideal for use in any masonry or concrete project.

Economical and Easy to Install

“FlashGard can be installed by hand with standard construction tools, unlike rigid flashing materials that require special tools to install. When used with Firestone’s FlashGard Thru-Wall Adhesive tape, FlashGard requires no contact adhesives or primers to fabricate field seams, corners or end dams.

FlashGard can be adhered to parapets, caps, lintels, windows, shelf angles and base flashing applications. It is compatible with a variety of substrates and can be installed in mortar; exposed at the edge or used in conjunction with a stainless steel drip edge. And because of its excellent low temperature (to -49° F) flexibility properties, FlashGard is easy to handle and install year round.

Greater Installation Freedom

FlashGard comes in a variety of panel sizes and is supported by a complete line of quality installation accessories including: Thru-Wall Adhesive Tape, Spray Primer, Polymer Batten Strip, Metal Termination Bar and Lap Sealant. This product line diversity gives the specifier greater design freedom in the selection of the right size membrane and accessories needed for a particular application.

Performance You Can Trust

Firestone’s commitment to producing quality rubber based products began over a century ago. The company was founded on the premise that it would offer not only superior materials, but also complete systems from a single source. That commitment is realized today in the billions of square feet of Firestone flexible membranes installed in a variety of demanding applications worldwide.
