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.
Gaco Western announces their roof assembly passes Severe Hail classification by FM Approvals. The GacoRoofFoam F2733 spray applied polyurethane foam coated with GacoFlex S2100 Cleanable Solvent-free Silicone Coating assembly was tested to meet: hail, wind uplift, corrosion, foot traffic, leakage resistance and accelerated weathering performance. Gaco’s is the only reflective silicone assembly to receive the Severe Hail classification. In addition, this assembly has the highest recycled content in the industry.
Building owners and design professionals are looking for a durable roofing solution. Gaco Western’s R & D team rose to the challenge to develop a system that stands alone and achieves a durability and toughness rating that eclipses other offerings in the reflective silicone coating market. The cleanability factor of GacoFlex S2100 adds to the longevity of this system as it maintains higher whiteness and solar reflectivity than other silicones.
FM Approvals certification is valuable to consumers because it means they can be confident they are getting a tested roof assembly, not a collection of products and parts that may or may not perform to expected levels. Severe Hail classification takes it a step further to give you confidence that Gaco Western offers a solution with strength and endurance.
Chuck Skalski, VP of Sales, GacoFlex commented, “Gaco is pleased to be providing our industry an FM Approved assembly that has been proven to withstand the most hail episodes. This is another testament to our commitment to innovation and providing solutions that last for many years.”
The Roofing Industry Committee on Weather Issues Inc. (RICOWI Inc.) has announced deployment of research teams to the Dallas/Fort Worth Metroplex hail-damaged areas. The teams will be conducting the investigation from May 2-6, 2016.
RICOWI is a non-profit international organization that has implemented a strategic plan for a Hail Investigation Program (HIP). The purpose of the research program is:
- To investigate the field performance of roofing assemblies after major hail storms.
- To factually describe roof assembly performance and modes of damage.
- To formally report the results for substantiated hail events.
Hail Task Force Chair John Gimple says: “The data collected will provide unbiased detailed information on the hail resistance of low slope and steep slope roofing systems from credible investigative teams. We can expect a greater industry understanding of what causes roofs to perform or fail in hail storms, leading to overall improvements in roof system durability, the reduction of waste generation from re-roofing activities, and a reduction in insurance losses that will lead to lower overall costs for the public.”
RICOWI investigated the Dallas-Fort Worth Metroplex in 2011. During this investigation more than 100 hail-damaged roofs were included in the research. RICOWI Inc. is again reaching out to the local governments, businesses and the residents to help with this important research project by volunteering their hail damaged roofs for the research project. All information is kept confidential and is used strictly for research purposes. Reports of past research are available for no charge on the website.
The published findings will document roofing systems that fail or survive major hail events and provide educational materials for roofing professionals to design hail-resistant roofing systems.
