As the demand for fire-resistant building materials continues to heat up, LP announced the addition of a FlameBlock® Fire-Rated OSB Sheathing line at its facility in Clarke County, Alabama. As the demand for fire-rated building products in single-family, multi-family and light commercial construction markets continues, the expansion of the mill will increase LP’s ability to meet the growing demand for fire-rated products, like LP FlameBlock.
But just how exactly does LP FlameBlock work to slow the spread of flames?
LP FlameBlock is an ICC-certified structural fire-rated OSB sheathing that combines fire resistance and impressive structural performance in a single panel. The fire-resistant coating bonded to LP® OSB allows for a 15-minute thermal barrier (UBC 26-2) and slows the spread of flame and heat.
Panels manufactured with Pyrotite® contain no less than two quarts of water per 32 square feet of panel. The water is released only during the heat of a fire, so as the temperature rises during a fire, water is gradually released, reducing the spread of flames.
A unique combination of flame-spread resistance and burn-through resistance, LP FlameBlock has a code compliant component of 1-hour and 2-hour fire-rated interior and exterior wall assemblies and roof decks. LP FlameBlock is backed by a 20-Year Transferrable Limited Warranty.*

Big builder market share has doubled in the last 25 years and now represents about 50 percent of housing starts nationwide – and even 75 percent in some major metro areas. These mega-builders have huge budgets for both land development and marketing. It’s increasingly difficult for small and medium-sized builders to compete, but LP is committed to helping them prosper.Continue Reading
To better serve its customers in areas of order accuracy and delivery predictability, LP has set some of the industry’s most aspirational supply chain goals. Senior leaders meet regularly with experts at Gartner, arguably the nation’s best consulting firm in the realm of supply chain optimization. The aim is to apply best practices in procurement, logistics and working capital across more than $1 billion of addressable spend.
For weather-resistant barriers (WRBs), ASTM has developed rigorous tests for water resistance and water penetration, plus an air barrier assembly test. But an equally important test is ASTM E96, which measures water vapor permeability over a 24-hour period.
When people talk about home “affordability” it boils down to one number: the asking price. But home “attainability” is a more complex equation. Attainability refers to a prospective buyer’s ability to find an entry-level home (no easy task these days), obtain a loan and pay for 30 years of ancillary costs like utilities, maintenance and insurance.
