New Ideas

Membrane is self-adhering

Benjamin Obdyke has introduced VaporDry SA, a self-adhering, vapor-permeable roof membrane.

The membrane features a continuous acrylic adhesive able to be repositioned during installation and self-seal around fasteners, allowing the membrane to serve as an air-control layer in addition to a moisture-control layer.

Said to withstand temperatures up to 250 F, the acrylic adhesive can be used under metal roof systems. The membrane’s tri-laminate structure also is durable under foot traffic, and a reinforcement scrim in the adhesive provides for more tensile strength. The surface is slip-resistant and features printed overlay guides for easier installation.

Flashing is flexible

Johns Manville Roofing Systems has launched the White EPDM Peel & Stick Flashing, an uncured flashing material said to eliminate the need for welding.

Compatible with TPO membrane roof systems, the White EPDM Peel & Stick Flashing features a release liner and factory laminated, self-adhering white EPDM tape. With the flexibility to work in traditionally difficult-to-flash areas, it allows for forming flashings around corners, pipe wraps and scuppers.

The flashing is available in a 60-mil thickness and in roll sizes of 6 inches by 100 feet, 9 inches by 50 feet and 12 inches by 50 feet. Inside and outside corners are available in 7 inches by 9 inches.

Spray foam roof system is protective

Huntsman Building Solutions has introduced Ultralok,™ a spray polyurethane foam roof system designed to deliver a fully adhered system that insulates, protects and waterproofs a variety of roof deck substrates.

Ultralok creates a monolithic membrane, eliminating the need for mechanical fasteners, and is said to be ideal for low-slope roofing applications in new and retrofit construction. The system reportedly conforms to any roof architecture and provides wind resistance.

Shingles are durable

IKO has made available the Armourshake Designer roof shingles. With a Class 3 Impact Resistance rating, the shingles are made with two laminated fiberglass mats for durability and dimensional thickness and feature algae resistance, ultraviolet-protective granules and a bonding sealant.

Armourshake Designer shingles are available in four colors: Chalet Wood, Grey Stone, Shadow Black (also available in Class 4 Impact Resistance rating) and Weathered Stone.

Metal panels are versatile

Innovative Metals Co. Inc. has launched Batten-Tite™ architectural metal roof panels. Designed for slopes of 3 inches or more and vertical wall applications, the system’s batten-style ribs are 1 7/8 inches high and are available in custom widths up to 44½ inches.

Batten-Tite panels are available in smooth or embossed surfaces and in a range of metals, including aluminum, copper, galvanized, stainless steel and zinc. Meeting ASTM E330 and ASTM E331 requirements, the panels can be applied over plywood or gypsum board with rigid insulation over decking.
