New Hybrid Snow Guard System

Alpine SnowGuards unveils the the Fusion-Guard, a hybrid snow guard system that offers the option of adding pipe-style snow guards to the new pad-style snow guard. According to the manufacturer, Fusion-Guard is a “best of both worlds” solution to managing snow on most new and existing roof types because it pairs the company’s newly designed pad-style snow guard with an optional pipe-style approach to managing snow. 

The system’s two optional 3/8-inch rods are accepted by the Fusion-Guard Rod Bracket, which fastens onto the back of the snow guard face, allowing the installer to add rods if desired during, or any time after, the initial installation. 

“This is the most versatile hybrid snow retention system that has ever been introduced to the snow retention marketplace. It gives the roofer or building owner the opportunity to manage the functionality of this snow management system more directly”, said Alpine SnowGuards’ President and Founder, Brian Stearns.  For more information, visit www.alpinesnowguards.com

Larger Base for Rooftop Support System

Green Link has engineered a new KnuckleHead 12-inch base — Big Base — designed to enhance the stability of larger rooftop-installed equipment. As with the standard universal base, the big base can be loose laid or attached. The new design features the standard universal KnuckleHead base in the center of a larger polyurethane base featuring a 12-inch diameter and 113.1 square inches of surface area. The standard universal base features a 7-inch diameter and 38.5 square inches of surface area. 

“As a loose-laid element, the Big Base brings increased stability and load capacity especially applicable to conditions involving high winds, seismic events, or installations that involve higher elevations from the roof surface that raise the center of gravity,” said Dan Olinger, Green Link President. 

Four holes at the center of the universal base extend through the larger polymeric base allowing for attachment to the roof. According to the company, attachment involving the big base results in an extremely secure installation because it combines the benefits of a larger footprint with the additional security of four screws secured in the roof deck. Green Link Adhesive/ Sealant adheres to the new big base for further strengthening and sealing the installation.

Rooftop Attachment Anchor Compatible With All Commercial Roofing Systems

OMG Roofing Products introduces PowerGrip Universal 7 (PGU-7), a rooftop attachment anchor for mounting solar racking systems and other products to virtually any commercial roof. PGU-7 units are designed to reduce or eliminate the need for ballast in solar racking systems, so there’s less weight, material handling and labor on the roof. 

Designed with wind performance in mind, PGU-7units offer up to 2,051 lbf. (9.12 kN) of tensile strength, 1,581 lbf. (7.03 kN) of shear strength, and up to 2,214 lbf. (9.84 kN) of compressive load strength, making it one of the strongest roof anchors on the market today.

Made of heavy-duty cast aluminum, PGU-7 units include a base ring that is secured through the roofing assembly and into the structural roof deck, as well as a waterproof cover plate to prevent water from infiltrating the system. 

“Commercial rooftop solar has continued to grow at a steady pace,” said Kevin Kervick, solar business manager for OMG Roofing Products. “In addition, the prevalence of damaging storms has increased dramatically over the past few years, which has reinforced the market need for stronger roof anchor systems, such as PGU-7s, which are easy-to-install. With our full family of PowerGrip products, OMG Roofing Products can provide appropriate anchors for virtually any rooftop solar installation.”

PGU-7 units transfer wind uplift loads to the structural roof deck for maximum strength and effectiveness. The system does not require any membrane welding, and PGU-7 units are typically installed in less than five minutes, saving both time and labor when compared to alternative options. 

In addition to ballast and rail-based solar racking systems, PGU-7s can be used for many other roof mounted items such as pipe supports, step crossovers, raceways, satellite dishes, small antennas and HVAC applications.

Universal Base Attachment Offers Increased Support Strength

Green Link Engineering has increased support strength by 40 percent on its Knuckehead universal base in response to customer needs in areas with high winds, seismic activity and other environmental fluctuations that can affect rooftop installations.

“Swings in weather patterns — high winds, and seismic events around the country, most recently in California, Puerto Rico and the Midwest — suggest the need for stronger, more stable installations of rooftop equipment. Responding to customer needs, we made a simple retool of our universal Knucklehead base without changing its basic design so that it now offers our customers the option to add more fasters to the base during installations,” said Dan Olinger, Green Link President. “When we heard from HVAC and roofing contractors about issues relating to equipment shifting during environmental events, we immediately looked at effective ways to retool our product to offer additional strength options. GreenLink prides itself on responding to customer needs and offering versatility in the use of our products. “

Greenlink Engineering’s retooled KnuckleHead universal base now offers an improved attachment feature for more secure installations. The universal base, which accepts a range of head designs, originally featured two holes for securing the base using screws that penetrate to the roof deck. The retooling now features four holes which allows for the doubling of mechanical fasteners. In laboratory tests, the four-fastener base installation increased support strength by 40 percent tested on a 12-inch strut Knucklehead configuration. No change has been made to the basic design of the base. The holes are still positioned in the center, and the base can also be further secured and sealed using specially formulated Green Link Adhesive/Sealant. 

A range of head designs can be fastened to the universal base for supporting struts, large pipes, small pipes, solar panels and pavers. KnuckleHeads offer a unique feature in that they can be attached or loose laid, depending on local conditions and specifications.

Multipurpose Roof Tape Protects Against Water Infiltration

IKO introduces GoldSeam, a multipurpose roof tape. This product can be used in a variety of deck-protection applications, including as a seam tape for the roof deck; a sealant for critical roof joints, such as small gaps around the eave and fascia; as well as around roof structures, such as skylights, chimneys, plumbing vents or ventilation caps. Designed to prevent ice and water infiltration as well as rodent and insect infestation, IKO GoldSeam is ideally suited to seal the joints of OSB (oriented strand board) or plywood roof deck panels when used in conjunction with an IKO underlayment, according to the manufacturer.

“Whether it’s roof deck or eave sealing, IKO GoldSeam provides the critical protection homeowners need to help prevent water infiltration inside their homes,” said Mark Okland, product development manager, North America. “Leading industry experts know that the gap between the fascia and roof deck is the most vulnerable area of the roof, and for far too long, has been the most overlooked detail in roof installation. IKO established an innovative solution with GoldSeam to effectively seal that gap and bring homeowners peace of mind.”

According to the company, IKO GoldSeam pairs perfectly with IKO’s Nordic and Dynasty performance shingles to provide superior protection for the entire roof system against blow-off and damage during extreme weather. IKO GoldSeam is also an accepted component of the Insurance Institute for Home and Business Safety’s (IBHS) FORTIFIED Home standards*. (Not all homes built using GoldSeam will qualify for a FORTIFIED Home designation. Homes require compliance with all FORTIFIED Home technical requirements and additional inspections. For more information, please visit www.fortifiedhome.org.)  

IKO GoldSeam is a specialized product that was designed to facilitate compliance with building codes requiring complete deck protection. Compliance with these regulations, which are particularly prevalent in areas where high winds are common, can usually be achieved by covering deck-panel joints with IKO GoldSeam in conjunction with a subsequent layer of synthetic underlayment, such as IKO Stormtite or RoofGard-Cool Grey. Prior to installation, applicable building codes should always be consulted, and all projects should be built in compliance with such codes.

New Acoustical Smoke Vent

The Bilco Company introduces the Type ACDSV Smoke Vent, which is specifically designed to provide fire and smoke protection for applications where exterior noise intrusion is undesirable, such as in auditoriums, concert halls, and theaters. The new ACDSV carries an OITC-46 sound rating to guard against low-frequency outdoor sounds such as traffic and airplane noises, and an STC 50 sound rating. In addition, the product has also received an ISO-140-18 sound rating when tested against rainfall sound. The figures are a significant improvement over BILCO’S previous model.

According to Michael Toohey, General Manager for The Bilco Company, “Our new Model ACDV features a number of upgrades and improvements over the Model ACDSH it replaces, yet still offers similar pricing and installation ease.”

“We’re especially pleased with the OITC rating the ACDSV earned,” continued Toohey. “While any noise can be disruptive to a concert-goer, lower-frequency sounds such as outdoor traffic, construction and airplane noises travel further and fall within the range where human hearing is most sensitive.”

“The OITC is the preferred rating when addressing sound insulation from exterior noise,’’ said Harold L. Merck, a principal and acoustician for Merck & Hill Consultants of Atlanta, Georgia. “While STC ratings may be fine for typical interior noise sources like voices, it does not adequately address the extended low-frequency noise contribution of aircraft, traffic, or even large roof-top equipment. This is similar to what we find with exterior windows in noisy environments — while a window with a relatively high STC rating might seem like it provides adequate exterior sound insulation, we frequently find that the ultimate interior noise impact is not significantly reduced due to low-frequency sound infiltration. Ratings that include the OITC are more useful to assess how well a window (or smoke vent) will isolate environmental noise.”

The manufacturer notes the ACDSV is the first automatic smoke vent to be rated with an ISO 140-18 Rainfall Sound Rating, which measures the impact sound insulation roof, skylights and roof/ceiling systems incur when exposed to artificial rainfall. Bilco’s new ACDSV’s rating of 37.5 dB features a nearly 9 percent improvement over Bilco’s previous four-cover smoke vent models.

According to the company, this new design features mineral wool insulation and high-density sound mat material within the unit’s covers and curb to better inhibit sound transmission. Structural improvements include the use of heavier gauge steel for the curb and cover liner, a new cover gasketing system, gas-spring lift assistance and a center-mounted gas traction spring to ensure reliable and controlled smoke vent operation. 

The new ACDSV is currently available in a number of standard sizes to meet the ventilation requirements of virtually any application. Custom sizes are also available when specified.
