NASHVILLE, Tenn. (Feb. 20, 2017)–LP Building Products recently added a new case study to its online product literature portfolio. The latest installment focuses on Habitat for Humanity’s nine-unit project in New Castle County, Delaware. LP® FlameBlock® Fire-Rated OSB Sheathing was used on all nine townhomes as a code-compliant component of a U350 2-hour partition wall assembly.

In March 2015, Habitat for Humanity of New Castle County broke ground on Walnut Ridge in Wilmington, Delaware. Walnut Ridge would consist of nine units in total, including a four-pack and a five-pack of single-family attached townhomes.

Director of Construction and Real Estate for Habitat for Humanity of New Castle County Sean Allen oversees all local builds. LP FlameBlock sheathing was recommended to him by John Connell, his trusted dealer at Grubb Lumber, who saw the product successfully used in townhomes in New Jersey.

Because the Habitat for Humanity townhomes are built by volunteers, Allen was intrigued to hear that the U350 assembly was a lighter, simpler solution than the traditional assembly using shaft wall liner.

“I would say the assemblies were built probably a month or two faster than a shaft wall assembly,” said Allen. “If this job had production builders on staff, I can see how this product would greatly affect the cost of a build because of time and labor savings.”

In total, approximately 270 sheets of LP FlameBlock sheathing were used throughout the nine townhomes. The site supervisors were able to easily instruct the volunteers on how to install the U350 assembly using LP FlameBlock sheathing.

The nine townhomes at Walnut Ridge are set to be complete in April 2017. Over 2,015 volunteer hours have been committed to the project.
