New Fluid-Applied Membrane Is Designed to Be Tough, Virtually Odorless, Easy to Apply

Garland’s first ever fluid-applied seamless membrane, LiquiTec, forms a virtually impenetrable surface over aged modified bitumen, metal and single-ply roof systems, adding years of waterproofing protection. LiquiTec is an aliphatic polyurea coating system with a tightly bonded molecular structure that provides strength and durability similar to truck bed liners. LiquiTec is built to protect roof surfaces from damage caused by hail, foot traffic, wind scour and other impact.

According to the manufacturer, LiquiTec fully and partially reinforced systems exhibit extremely high tensile strength and remain flexible at temperatures down to -60°F (-51°C), which helps keep the coating from cracking or becoming brittle to ensure a complete watertight seal and long-term waterproofing protection. In addition to its strength, LiquiTec contains zero VOCs and is extremely low odor to allow roof work to be completed with minimal or no disruption at sensitive locations like schools, hospitals and other structures where people are present. 

This two-component product also undergoes a chemical cure process, rather than a moisture cure, so it cures quickly and with less disruption from weather, allowing for faster installation and waterproofing protection. 

“LiquiTec is the answer to so many of our customers’ waterproofing needs. Its unique formulation, strength and flexibility provides the right amount of toughness combined with superior waterproofing protection,” said Ed Buczek, Garland’s senior product manager of roof coatings. “And to top it off, the fact that it is extremely low odor, highly flexible, resistant to fungi and chemically cured allows it to be installed nearly anywhere and perform in the most extreme environments.”

High Wind-Resistant Roofing System

Polyglass announces the new Velociflex high wind-resistant roof assembly system. Independently tested, the Velociflex system provides for high-speed wind protection up to 270 psf (pounds/square foot).

The core of Velociflex is two or three plies of reinforced modified bitumen membranes. Suitable for new or re-roofing projects, this multi-ply system comprises of a mechanically fastened base sheet, optional interply, and a heat-welded or cold-applied cap sheet. According to the manufacturer, Velociflex is ideal for both steel and concrete decks.

The self-venting Velociflex system’s “loose-laid,” mechanically attached base sheet reduces the likelihood of blistering from substrate to membrane. Attached at the seams only, it also limits material and labor costs. Plus, the watertight system acts as a temporary roof once base sheet seams are heat-welded. Fast and efficient to install, the Velociflex system dries in fast, so projects can proceed with phased construction before cap sheet installation. 

Installed with a Polyfresko G cap sheet with initial Solar Reflective Index 96, the Velociflex system complies with 2016 Title 24 Part 6 Cool Roof Requirements and is ENERGY STAR Certified. The Velociflex system is also compatible with a variety of SBS and APP cap sheets from Polyglass, including Elastoflex, Polyflex, and Elastoshield membranes.

Stone Wool Insulation Board Is Thermally Efficient, Non-Combustible

HARDROCK (DD) TRB (Thermal Roof Board) is a rigid, dual-density stone wool insulation which is purpose-designed to give an enhanced thermal performance across roofs that are subject to maintenance-only foot traffic. Manufactured using Rockwool’s patented dual-density technology, this A1 non-combustible thermal roof insulation board is ideal for large flat roof areas typically found on storage, logistics and distribution centers, as well as for education, healthcare and residential roofing applications.

“The roof is often overlooked in terms of fire safety, particularly from a regulatory standpoint, which can result in specifiers inadvertently yet routinely introducing a weak link into the building envelope via the unconsidered ‘fifth façade,’” said Will Wigfield, Product Manager at Rockwool. “However, there now exists a non-combustible flat roof insulation capable of meeting stringent thermal requirements in just one layer – offering contractors a quick and easy install without compromising fire safety. HARDROCK (DD) TRB achieves the highest-attainable Euroclass A1 rating under EN 13501-1, meaning that it simply will not burn.”” 

According to the manufacturer, HARDROCK (DD) TRB is easy to handle on site, and in the majority of applications can be securely installed within a mechanically-fixed single-ply waterproofing system using just one fixing per board, in contrast to the multiple fixings needed with PIR / PUR foam board installation. (Note: Exceptions may occur that demand multiple fixings, including, for example, the corner regions of flat roof systems, which are subject to increased external suction and internal pressure force, and require more fasteners.) The result is a quick and simple installation, reducing any risks of cold bridging that may otherwise compromise thermal performance. The product is also compatible with all commonly used flat roof membranes, including single-ply and EPDM, bitumen membranes and liquid-applied systems.

Manufactured from basalt rock, which is melted, spun and bound to create stone wool insulation boards, HARDROCK (DD) TRB is dimensionally stable, eliminating the need for any mechanical fasteners to prevent differential thermal expansion and undue stress on the waterproofing membrane. It is also water repellent and completely unaffected by damage caused by the freeze/thaw cycle, according to the manufacturer.

HARDROCK (DD) TRB Thermal Roof Boardis available as a specification-only product, supported by Rockwool’s Technical Solutions team who can provide U-value calculations, BIM modelling, and detailed technical guidance for all projects.

New EPDM Membrane Designed to Reduce Installation Time and Effort

Firestone Building Products Company LLC(FSBP) introduces FullForce EPDM, the next evolution of Secure Bond systems. According to the manufacturer, FullForce EPDM can be installed more than four times faster than standard adhered EPDM and in temperatures as low as 20 degrees Fahrenheit, allowing contractors to complete more jobs throughout the entire roofing season.

FullForce is the industry’s only EPDM membrane fully coated from seam to seam with Firestone’s factory-applied Secure Bond pressure-sensitive adhesive. With no seam tape, FullForce can be installed more quickly than traditional EPDM, offering valuable time savings for contractors and allowing roofers to get more projects done in a year. Additionally, the solution is ideal for occupied buildings and building owners, as it contains zero volatile organic compounds (VOCs).

“FSBP is committed to providing contractors with innovative solutions that make their lives easier while delivering on the long-term reliability they expect from the Firestone brand,” said Taylor Cole, president, FSBP. “FullForce EPDM exemplifies this commitment by empowering contractors to optimize their operations, which results in the opportunity for more revenue in a season.”

Hoekstra Roofing Company, based in Kalamazoo, Michigan, was one of the first contractors to experience the time and labor savings of FullForce EPDM during a third-party time study conducted on one of its recent projects, Green Bay Packaging Inc. According to the study, Hoekstra Roofing’s four-person crew was able to install a 10-foot by 100-foot FullForce EPDM self-adhering membrane in just under 8 minutes versus nearly 36 minutes to install a traditional EPDM membrane of the same size.

“We have been in the roofing business for more than 100 years and have consistently used Firestone solutions for more than three decades,” said Steve Hoekstra, president, Hoekstra Roofing Company. “When the opportunity came along to test FullForce EPDM, we could not wait to explore the solution’s features for ourselves. Our whole team was immediately impressed by the installation speed and efficiency of this solution, as well as how easy it was to handle the product.”

Hoekstra is among the many contractors identifying ways to complete roofing projects more efficiently, in the face of increased industry labor shortages. “In addition to installing more quickly than traditional EPDM, we also anticipate a lower likelihood of re-work due to FullForce featuring factory applied adhesive, which allows consistency of application at the product’s seams,” Hoekstra said. “These benefits mean we are able to lay more squares in a day, allowing us to complete more projects in a season and take on new business we couldn’t take on before.”

White Mod-Bit Cap Sheets Offer Superior Granule Embedment

Polyglass U.S.A. Inc. announces important new updates to Polyfresko, a highly-reflective, white modified bitumen membrane cap sheet used as the final layer in a multi-ply roof system or as a flashing membrane. 

According to the manufacturer, independent laboratory testing confirms Polyfresko’s superior granule embedment and documents its aged reflectivity performance. Granule embedment was tested using ASTM D4977 Standard Test Method for Granule Adhesion to Mineral Surfaced Roofing by abrasion. The recently completed three-year aged reflectivity testing was conducted in three different climate zones, and demonstrated that Polyfresko maintains reflectivity performance over time. The product was deemed suitable for most Cool Roof specifications due to Polyfresko’s initial and aged reflectivity and emissivity performance. The laboratory testing results enabled Polyfresko to gain Energy Star Certification.

Polyfresko is manufactured with proprietary CURE Technology, a thin film technology infused with ceramic microspheres, ultraviolet (UV) stabilizers, and proprietary resins. This increases weatherability and decreases maintenance costs by “locking-in” the granules, so the high-performing Polyfresko membrane maintains reflectivity performance over time, decreases UV degradation, and increases abrasion and impact resistance. 

In addition, all Polyfresko products are now manufactured with FASTLap technology, a patented granule-free end lap that helps make the membrane watertight and increases speed of installation. Polyfresko is available in Polyglass’s APP (Atactic Polypropylene) and SBS (Styrene-Butadiene-Styrene) formulations and is adhered to the roof deck or other approved substrates by torching or self-adhered application.

“Granule loss is one of the challenges with modified bitumen membranes, and our new granule adhesion testing results show that Polyfresko is a premium solution, firmly positioned as a top performing product,” says Polyglass CEO Natalino Zanchetta. “The granule adhesion results achieved with our CURE Technology, together with our new three-year weathering milestone, demonstrate our leadership with asphaltic membrane cap sheet performance.”
