Boise Cascade adds engineered wood I-joists with mineral wool insulation to fire-resistant joist range; product is designed to solve energy conservation code provisions relating to floor cavity insulation as well as fire resistance requirements
May 28, 2014
– Boise Cascade Engineered Wood Products, a business unit of Boise Cascade Company headquartered in Boise, Idaho, has announced yet another fire-resistant joist product or product installation technique designed to increase residential fire protection. This newest release combines Boise Cascade engineered wood I-joists with mineral wool insulation to insulate better and suppress residential fires for longer periods of time. These products solve two important code issues – energy conservation code provisions regarding insulation in the floor cavity and fire resistance requirements. Mineral wool insulation has a long history of success in fire suppression, is available across the U.S. and is compatible with every depth of Boise Cascade AJS® series and BCI® 60 or 90-series I-joist.
Another main advantage of the Boise Cascade I-joist with mineral wool insulation system is the ease of installing its more stable insulation batts. Mineral wool insulation has more "body" than glass fiber insulation, enabling precise cutting and snug fitting for better insulating properties and easier installation -- easily dropping into place between I-joist webs, atop the bottom flanges. This pairing of Boise Cascade I-joists and mineral wool insulation solves two code issues – the evolving energy conservation code provisions regarding insulation in the floor cavity, and fire resistance requirements for light frame construction, both specific to floor framing over unfinished basements. According to the U.S. Department of Energy, mineral wool insulation typically consists of 75% or greater recycled content, while glass fiber insulation contains only about 20-30% recycled content, making mineral wool insulation more eco-friendly. Mineral wool insulation is also water repellant and resistant to mold.
The four Boise Cascade residential fire-resistant tools are 1) Horizontal direct installation of gypsum to BCI® or AJS® joists; 2) Installation of mineral wool insulation between BCI® or AJS® joists; 3) BCI® or AJS® floor joists with partial sprinkler systems (part of the residential cold water system); and 4) Web Armor™ pairing BCI® or AJS® I-joists with gypsum, a natural fire fighter. This much choice gives homebuilders many different tools for increasing the fire-resistant capabilities of their new homes, and positions Boise Cascade as a leader in fire-resistant joist development and installation.
Boise Cascade manufactures and markets engineered wood products -- building products with improved structural characteristics that use wood fiber more efficiently.
