The polyurethane foam is applied in a single step. Both parts of the adhesive are ready to use from the container – no mixing required – and are applied simultaneously in a 1:1 ratio through a static mix tip. It is applied in continuous ribbons or beads spaced 4, 6 or 12 inches apart, depending on the project and code requirements. There is no overspray, and it cures in minutes.
Helix Low-Rise Adhesive contains no volatile organic compounds (VOCs), chlorofluorocarbons (CFCs) or hydro chlorofluorocarbons (HCFCs).
It does not require mechanical fasteners, maintaining a puncture-free vapor retarder, preventing thermal bridging and protecting the structural integrity of the roof deck.
The bond created by Helix Low-Rise Adhesive provides wind uplift resistance, allowing it to be used on buildings in higher wind zones. In addition, it provides hail resistance when used as an adhesive for fleece-backed membranes.
Helix Low-Rise Adhesive comes in cartridge twin-pack tubes or two-tank sets. Both include one container of each of the adhesive’s two components – Part A and Part B. Cartridge twin-packs cover approximately 200-600 square feet of roof and tank sets cover approximately 1,000-3,000 square feet of roof, depending on bead spacing.
The cartridges fit most dispensing guns currently available on the market. Tank sets come with a Helix Gun Assembly (25-foot dual-hose with attached spray gun), petroleum packet, wrench, and 10 Tank Static Mix Tips. Contractors need not purchase specialty pumps or spray rigs. No external power source is required to run application equipment.
- No special width membrane needed.
- No membrane to install between purlins.
- No penetrations of the new membrane.
- No excess membrane buried in the laps.
- No membrane orientation issues.
- No fastener jacking.
GAF has completed an extensive roof replacement project at its new corporate headquarters at 1 Campus Drive in Parsippany, N.J. GAF has been relocating to the new property, which has been completely renovated with quality products in all areas—including, of course, the roof.
GAF worked closely with its Master Select Contractors to ensure the installation of an energy-efficient roofing system at 1 Campus Drive. The system included GAF’s RUBEROID HW 25 Smooth Membrane, EnergyGuard Polyiso Insulation (for high insulation value), and EnergyGuard HD Cover Board (which offers a high R-value and impact resistance). It also included GAF’s single-ply membrane, EverGuard Extreme Fleece-back TPO Membrane. GAF is proud of how EverGuard Extreme Fleece-back TPO Membrane outperforms competitive TPO membranes (based on heat-aging tests), and backs it with a commercial roofing guarantee.
As GAF prepared to move into its corporate headquarters, it was imperative to make sure they had a durable, energy-efficient and easy-to-install roofing system. The combination of GAF EverGuard Extreme Fleece-back TPO Membrane in 2-Part Roofing Adhesive over EnergyGuard HD Cover Board and EnergyGuard Polyiso Insulation set in Olybond, along with RUBEROID HW 25 Smooth Membrane was the perfect system to keep its building dry and comfortable for years to come.
When using EverGuard Extreme Fleece-Back TPO Membrane with Low-Rise Foam Adhesive (compared to EverGuard Extreme Smooth TPO Membrane), the fleece on the back of the membrane provides an added cushioning layer, especially for hail-prone areas. Also, when combining EverGuard Extreme TPO Accessories with EverGuard Extreme Fleece-Back TPO Membrane, it helps save labor (versus field fabrication)—and provides an overall cleaner-looking roof.
