LP Building Solutions announced that ASTM International has validated five Structural Solutions products as carbon negative. In the newly published environmental product declarations (EPDs), LP TechShield Radiant Barrier, LP WeatherLogic Air & Water Barrier, LP Legacy Premium Sub-Flooring, LP FlameBlock Fire-Rated Sheathing, and LP TopNotch 350 Durable Sub-Flooring have all been shown to store more carbon than is released during their entire life cycle.

LP said the company is “deeply committed” to providing solutions for builders to address the many environmental challenges facing the industry. The entire LP Structural Solutions product portfolio, excluding LP NovaCore Thermal Insulated Sheathing which is too new to qualify for testing and analysis, hsa been confirmed to be carbon negative.

“In addition to the proven benefits of LP Structural Solutions, such as their resilience and durability, confirming that our products are carbon negative helps us live up to LP’s purpose of Building a Better World,” LP executive vice president and general manager of OSB Jimmy Mason said. “LP has long been dedicated to using renewable resources and developing resilient, high-performing and sustainable products to make the lives of our builder community easier. This new designation is the latest evidence of our long history of fulfilling this commitment.”

EPDs provide transparency to consumers about the environmental footprint of products throughout their entire life cycle, from raw material sourcing to product end of life. To establish the products’ carbon-negative designation, LP developed life cycle assessments and EPDs for each product in line with internationally recognized protocols and standards. LP said it began the EPD process in 2022 to determine the cradle-to-grave energy, fuel, and materials needed to produce and distribute LP Structural Solutions products in North America. Once completed, the life cycle assessment and EPDs underwent third-party validation by ASTM International.

LP has released six EPDs since 2021, demonstrating the carbon negativity of products across the LP Structural Solutions and LP SmartSide Trim & Siding product lines.

“Earning the assurance that all eligible products in our Structural Solutions portfolio are carbon negative is an important milestone for the company,” said LP Structural Solutions brand manager Casey Smyth. “We are incredibly proud to offer a sustainable structural portfolio to the market. Not only does our portfolio meet increasing customer demand for products originating from sustainably sourced, renewable resources, it also provides peace of mind to builders who can rest assured that their product choices are positively impacting the environment.”
