Build Better With Biewer: Biewer FRTW Delivers Code-Compliant, Eco-Friendly Fire Protection for Modern Construction

In an era where building safety and being eco-friendly are critical, Biewer Fire-Retardant Treated Wood (FRTW) provides a code compliant solution for the building industry. For over 40 years, builders and homeowners have trusted Biewer Lumber Fire Retardant Specialists to provide the highest quality fire-treated wood. As contractors navigate stringent fire codes while delivering aesthetically pleasing and durable structures, Biewer FRTW offers a reliable solution that balances performance, compliance, and versatility.

Biewer’s treatment process pressure-impregnates wood with FlamePRO fire-retardant chemicals without compromising structural integrity or workability. Contractors can make traditional joining cuts, end cuts and drill holes without adversely affecting the fire retardant performance and no field treatment is required to maintain the flame spread rating. This pressure impregnated treatment is vital to meeting the International Code Council (ICC) requirement for treatment during the manufacturing stage.

Fire safety is an ever-rising concern in commercial and residential projects. According to the National Fire Protection Association, over 350,000 structure fires occur annually in the U.S., underscoring the need for materials that mitigate fire risks. The ICC code has been updated in recent years to improve fire hardening practices in building construction. This included clarification of allowable fire-retardant treatments. Surface applied fire-retardant products are not equal to pressure-impregnated treatments, do not provide adequate protection, and are not accepted in the building code. Topical fire-retardant treatments are not appropriate where fire retardant treated wood is required.

Biewer FRTW is pressure-impregnated in the manufacturing process to be fully code compliant. Biewer FRTW is engineered to resist flame spread and smoke development, meeting or exceeding standards like ASTM E84 and UL 723. Smoke inhalation containing toxic gases as a byproduct of structure fires is a major cause of injury and loss of life. This makes Biewer FRTW - with multiple environmental certifications - an ideal choice for interior applications such as walls, ceilings, and partitions, where fire resistance is a vital part of the life safety conversation.

The FlamePRO fire retardant chemical is quality monitored by independent inspection agencies for environmentally safe practices. FlamePRO fire retardant is UL Greenguard GOLD certified, meaning it has under rigorous testing and met stringent standards for low-VOC emissions. This means it’s safe for schools, hospitals, offices, and other sensitive environments where occupant well-being is critical. By choosing Biewer FRTW, you’re contributing to safer building practices without sacrificing performance.

Biewer FRTW’s versatility suits diverse applications, from multifamily housing to commercial spaces like auditoriums and retail centers. It meets Class A fire ratings and noncombustible material requirements while remaining compatible with paints and stains for finishing. Biewer’s rigorous quality control ensures consistent performance, giving contractors peace of mind in high-stakes projects.
