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.

New Non-Penetrating Attachment Solution for Standing Seam Metal Roofs

S-5!’s new GripperFix technology ensures a secure and dependable attachment solution that preserves the integrity of the roof and avoids destructive corrosion. According to the company, this system is quick and simple to install, lasts the life of the roof, maintains roof warranties and is less expensive than other mounting methods. Gripper fix uses S-5 seam clamps or mini clamps to make a secure maintenance-free attachment to any standing seam metal roof using patented non-penetrating S-5 technology. 

Traditionally, mounting rooftop ancillary items using concrete blocks for ballast damages a roof and provides a temporary fix. Wooden dunnage causes early corrosion. According to the company, S-5!’s new GripperFix technology ensures a secure and dependable attachment solution that preserves the integrity of the roof and avoids destructive corrosion.  

S-5! will introduce its new GripperFix technology February 4-6 at the International Roofing Expo (IRE) in Dallas. Attendees are invited to stop by S-5! Booth #2622 to see firsthand its new universal GripperFix system, which makes mounting almost anything on standing seam and exposed-fastener roof profiles simple and easy.

Metal Roofing and Siding Panel Recreates Look of Reclaimed Metal

Reclaimed Metal Rust is a new pre-painted metal roofing and siding panel from Western States Metal Roofing that recreates the look of reclaimed metal. The panel is made of new steel that looks like an old barn. The panel features white and silver coloring with orange and reddish rust streaks throughout its design to mimic the look of old, faded galvanized that is rusting. The panel is available in Kynar 500 paint system and comes in ten different profile finishes.

Reclaimed Metal Rust is a proprietary color of Western States Metal Roofing and offers a solution for architects and designers that want the look of reclaimed metal without the problems of reclaimed metal. 

“Our customers wanted something that looks like faded galvanized and a rusted roof at the same time. Previously, the only way to get something like that would be to locate an old building that had reclaimed sheet metal on the roof,” said Paul Rubio, Vice President of Western States Metal Roofing. “That’s expensive and hard to find. We thought there has to be a better way. That led us to create the Reclaimed Metal Rust panels, which are new steel panels that look like they were taken from an old barn that’s 100 years old.” 

According to the company, this specialty paint print is available in coil, flats, metal roofing, siding, and wall panels. Reclaimed Metal Rust panels come in a PVDF/Kynar 500 paint finish. These panels are designed for interior and exterior applications. 

Western States Metal Roofing will premier metal Reclaimed Metal Rust at the International Roofing Expo on February 4, 2020. Visitors to the Western States Metal Roofing booth (#1526) at the 2020 IRE Show will be able to view and order panels in Reclaimed Metal Rust for their projects at an exclusive introductory offer. Architects, roofing contractors, and general contractors are encouraged to bring their material lists to the show for a free quote.

Energy-Efficient Translucent Windows Designed for Smaller Envelope Openings

Kingspan Light + Air North America has scaled the size of the company’s innovative two-panel UniQuad system to create the more modular and versatile UniQuad Translucent Windows for smaller envelope openings. 

According to the company, architects can expect the same durability, seamless integration and clean look they have for years from the UniQuad system — just in a smaller size. Providing 25 percent greater light transmission than other daylighting products on the market, UniQuad eliminates glare and hot spots found in glass applications, allowing for a more controlled indoor environment. 

 “We’ve taken our innovative two-panel UniQuad system and scaled it to create something more efficient for smaller applications,” said Rafael Rivero, VP of Commercial, Kingspan Light + Air. “Ideal for both new and retrofit projects, the UniQuad Translucent Windows are the solution for any size building looking to reap the full health and wellness benefits of glare-free daylighting.” 

Available in heights up to 6 feet, UniQuad Translucent Windows can be built in limitless lengths. With the ability to specify custom window sizes and colors, the two-panel system allows buildings to coordinate with corporate or campus colors, or design a new and innovative look.  

UniQuad Translucent Windows feature the same two-panel composition with Removeable Skin Technology (RST) as the UniQuad system, allowing for the removal of the exterior panel while the interior panel remains in place. Additional insulation can be added between the two panels to improve thermal performance and further increase efficiency.

According to the manufacturer, UniQuad Translucent Windows can help buildings achieve LEED certification and other sustainability goals and are NFRC certified. UniQuad Translucent Windows come with a 10-year warranty against discoloration, loss of translucence, delamination and color change.

New Steel and Aluminum Standing Seam Roof Panel Offers Bi-Directional Installation

Petersen expands its line of PAC-CLAD standing seam roof products with the addition of the T-250 panel. Combining structural performance with architectural aesthetics, architects will enjoy the bolder profile of the T-250, installing contractors will appreciate the bi-directional installation capabilities and building owners will benefit from the panel’s impressive strength.

The strongest of all PAC-CLAD roof products, the T-250 panel is available in 16- and 18-inch widths in multiple gauges of steel and aluminum. T-250 features a nominal 2.65-inch seam height above the roof deck. It is available in all 45 standard PAC-CLAD colors, each of which carries a 30-year non-prorated finish warranty. A weathertightness warranty also is available.

“Our T-250 panel satisfies the needs of architects designing structures that include expansive roof areas requiring long panel runs” said Mike Petersen, president. “Plus, architects might also prefer the wider seam of the T-250 panel, which creates bold shadow lines. The T-250 panel follows Petersen’s drive to continue adding products that expand the creative palette of building designers.”

Standard panel condition for the T-250 is with striations, but smooth is an option. The T-250 is available in 24 and 22 gauge steel, and .032 and .040 gauge aluminum. The T-250 can be specified with a traditional intermittent fastening clip, or a continuous clip fastening system for high-performance open-framing scenarios where extra strength is required. Both clips allow for thermal expansion and contraction. Job-specific design calculations should be performed to determine the type of clip required.

The panel is bi-directional, which allows installers to position the first panel in the center of a roof and install simultaneously in both directions, making it easy to achieve an attractive symmetrical look, while allowing multiple crews to work at the same time.

Named for the shape created where two panels meet, the T-250 is a symmetrical panel whose seams form the letter T. A metal cap is placed over the T and a mechanical seamer bends each side of the cap under the top of the T to form a strong bond. The T-250 panel is equipped with the following tests: ASTM 283, 331, 1680, 1646, E1592 and E2140, plus FM 4474 as well as UL 580 and 1897.

PAC T-250 panels can be factory- or field-formed to length but must be field-seamed. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1/2:12. Sealant beads are factory-applied to the seam cover. The seam cover is roll formed in the factory.

Substrates may include 5/8-inch minimum plywood, nailboard insulation or equal with WIP 300 underlayment applied horizontally from eave to ridge. Other substrates may include metal decking, purlins or rigid insulation in conjunction with bearing plates, and open framing.

Maximum factory-produced panel length for the T-250 is 54 feet, but longer lengths are available through field forming. Seam covers will be limited to 30-foot maximum lengths and must be field-lapped.
