LP Building Products Debuts LP® FlameBlock® I-Joist

NASHVILLE, Tenn. (Jan. 18 2016)– LP Building Products has announced the launch of the LP® FlameBlock® I-Joist to help builders find a new innovative solution for the latest “Fire Protection of Floors” section of the 2012 IRC (R501.3). This product combines the strength of an LP® SolidStart® I-Joist with LP FlameBlock’s proven, patented, non-combustible Pyrotite® coating to slow the effects of heat and flames.

“From architects to builders the building industry is faced with adapting to new fire codes, and the LP FlameBlock I-Joist meets both the 2012 and 2015 IRC codes,” said Lisa Reese, EWP marketing associate for LP Building Products. “Moreover, this new product brings the demonstrated performance of LP FlameBlock to the line of LP SolidStart products to further enhance the performance and innovation that builders and homeowners have come to expect from LP.”

Reese continued, “In addition to the fire-resistant characteristics, this product was designed with ease of installation in mind. Uniform properties allow the joist to be installed with either flange up, and it fits in commonly available hangers. The 2-1/2˝ wide flange offers easier handling and more nailing/glue surface, and a thicker web makes floors feel firmer.”

LP FlameBlock I-Joists are backed by the LP SolidStart lifetime limited warranty. For full warranty details, visit or call 1-888-820-0325. Please check with an LP SolidStart distributor in your area for availability.
