In a new video available on YouTube®, Viance showcases UL® Design V335, a robust 2-hour rated firewall construction utilizing D-Blaze treated wood. This video explores the unique benefits of the V335 design, specifically highlighting its enhanced fire resistance and structural integrity when compared to alternative designs using fire-retardant spray or coatings. This demonstration is invaluable for contractors, architects, and builders seeking a high-performance, reliable fire-rated wall solution. Viewers will gain insights into why D-Blaze-treated wood outperforms other fire-retardant methods in maintaining both fire containment and structural stability.
The video showcases UL Design V335’s composition, which includes D-Blaze-treated lumber and plywood, two layers of gypsum drywall, insulation, and an exterior facing of brick, cement, or plaster. This configuration offers a finish rating of 52 minutes, meaning the wall remains intact and structurally sound under fire exposure for a longer duration compared to traditional spray-coated walls, which can begin to lose stability in as little as 23 minutes. By maintaining structural integrity longer, V335 helps to prevent the fire from spreading to adjoining buildings, providing added safety to multi-unit structures.
Another critical point highlighted in the video is the durability and handling advantages of D-Blaze-treated wood. Unlike spray-coated walls, where the coating can be compromised if chipped or penetrated, D-Blaze-treated wood does not require patching or precise nailing adjustments. Additionally, D-Blaze-treated plywood weighs less than its coated counterparts, making it safer and easier to handle during installation, as it adheres to OSHA’s recommended weight limits for single-person lifts. This feature alone can significantly reduce on-site labor challenges and increase overall efficiency.
The video also emphasizes D-Blaze’s proven track record, with its fire-retardant treated wood being used in iconic structures like the One World Trade Center and the Willis Tower. By viewing this informative video, industry professionals can see firsthand the superiority of UL Design V335 and understand why D-Blaze is trusted in high-profile construction projects. Don’t miss this opportunity to learn how UL Design V335 can enhance safety, reliability, and efficiency in your fire-rated wall projects.
