Lantz-Boggio Architects Finds Simple Transition Between 1-hour and 2-hour Wall Assemblies Using LP^® FlameBlock^® Fire-Rated OSB Sheathing

NASHVILLE, Tenn. (May 9, 2017) – LP Building Products recently added a new case study to its online product literature portfolio. The latest installment focuses on Lantz-Boggio Architects and their newly designed project, The Legacy Village at Castle Pines, a 176-unit continuing care senior living campus in Castle Pines, Colorado. LP® FlameBlock® Fire-Rated OSB Sheathing was used as a code-compliant component of both 1-hour and 2-hour UL-listed fire-rated wall assemblies.

A portion of the building has 2-hour load-bearing walls with 1-hour walls stacked on top. Dwight Miller, Associate Principal at Lantz-Boggio Architects, was seeking wall assembly solutions that would provide a consistent plane across both 1-hour and 2-hour fire-rated wall assemblies. 

Miller specified 2-sided LP FlameBlock sheathing as a code-compliant component of the U349 2-hour fire-rated wall assembly and 1-sided LP FlameBlock sheathing as a code-compliant component of the U348 1-hour fire-rated wall assembly.

“When using plywood or structural wood panels behind the gypsum sheathing on the exterior side of the wall, there is the material and labor cost to install at least two layers of sheathing, as well as the additional schedule time for installation and inspections of multiple layers. Secondly, to have a 2-hour exterior wall that is stacked below a 1-hour exterior wall would either require some means of transitioning between the change in plane, or to continue the third layer of gypsum sheathing up the 1-hour wall,” said Miller. “By using the 1-sided and 2-sided FlameBlock, I was able to overcome all of these obstacles with two products that are easily identifiable by the contractor (based on the 1-side or 2-side coating) and that install the same as regular plywood.”
