Specifying 1 Hour Fire-Rated Walls

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.

Building Smarter Starts With Smashing Silos

One of the most vexing problems in home construction is that productivity isn’t rising fast enough – even though there are fabulous productivity tools everywhere you look. Making a process lean and efficient isn’t always the answer, according to John Murphy from the consulting firm FMI. Sometimes a process can be scrapped entirely, which in turn causes productivity to soar. But it can only happen when all the key stakeholders – developers, designers, manufacturers and builders – tear down their respective silos and start collaborating more effectively.

A Solution for the Labor Shortage?

The on-going shortage of skilled labor in the construction field is forcing manufacturers to find creative ways to deal with it, particularly in product design and training. First, the products themselves need to be intuitive and designed to eliminate unnecessary mistakes. Sub-flooring products offer a good example of how to design for easy installation.
