For about a century, architects and builders have used gypsum panels in wall assemblies to meet the testing criteria for 1 hour fire-rated walls. As product engineering develops, more and more architects are now looking for product solutions that bring added value to their 1 hour fire-rated walls. Many are specifying LP® FlameBlock® Fire-Rated OSB Sheathing because it meets building codes while providing faster and easier installation than assemblies that use gypsum and structural panels. They can also provide added design flexibility by reducing wall thickness.
LP FlameBlock sheathing can be used in a few different 1 hour fire-rated wall assemblies, including:
Intertek Design LPB/WPPS-60-01:This Intertek-listed assembly is commonly used in 1 hour exterior walls along the property line, including single-family construction. This assembly is fire-rated for 1 hour from both sides.
UL Design U348: This UL-listed assembly is commonly used in Type V multifamily construction in load-bearing exterior walls. It also allows for the use of fiberglass insulation. This assembly is fire-rated for 1 hour from the interior side only, except when brick is the exterior facing.
When specified for these 1 hour fire-rated assemblies, LP FlameBlock sheathing reduces dead load and wall thickness versus common alternatives. It also providesbetter substrate for securely fastening exterior facing materials. Unlike gypsum, LP FlameBlock sheathing has an Exposure 1 classification—which means it can withstand normal exposure to moisture during construction.
Fire-rated walls shouldn’t interfere with your design capabilities and construction schedules. Check out our LP FlameBlock page to learn more about the U348 and WPPS-60-1 assemblies.
LP Building Solutions uses engineered wood to create a portfolio of products that help professionals build smarter, better and faster. The innovations of engineered wood siding are relatively new. For instance, LP® SmartSide® Trim & Siding was introduced in 1997. Thanks to its advanced manufacturing process, it is one of the most durable siding solutions available. Sometimes people are skeptical of things that are really that good. So, let’s crush a few myths with engineered wood facts.Continue Reading
Pier and beam design was among the most popular foundation techniques until the 1960s when concrete technology improved its floating slab system. Many builders use slab-on-grade construction—especially in warmer regions. We’re going to find out why professionals Jordan Smith of @jordansmithbuilds and Kyle Stumpenhorst of @rrbuildings chose pier and beam over slab-on-grade for the All-in-LP Build in Bellville, Texas. But first, let’s delve into pier and beam foundation.
From destructive hurricanes to fierce tornadoes, it seems news of catastrophic events is happening with alarming frequency. In fact, on March 3, 2020, an EF3 tornado tracked less than one mile from the LP Building Solutions headquarters in downtown Nashville, Tennessee, ripping through homes and businesses. While no traditional building can withstand the tremendous forces of disastrous weather events, it reminds us that embracing resilient construction and adopting stronger building codes could help protect our families, friends and neighbors.
