TimberTech® Sets New Industry Standard with Top-Rated Fire Resistance for Composite Decking; Best Choice for Fire Zones

The AZEK Company Inc. (NYSE: AZEK) ("AZEK" or the "Company"), the industry-leading manufacturer of beautiful, low-maintenance and environmentally sustainable outdoor living products, including TimberTech^® decking and railing, Versatex^® and AZEK^® Trim, and StruXure^® pergolas, is proud to announce that its TimberTech Advanced PVC Vintage Collection® and Landmark Collection® are the first in the composite decking industry to receive an Ignition Resistant designation from California's State Fire Marshal. Ignition Resistance, as defined by the California State Fire Marshal, and by the surrounding states that have adopted its standards, refers to building materials that resist catching fire or burning easily and that may slow the spread of flames. The new Ignition Resistant designation for these Advanced PVC Collections underscores TimberTech's commitment to providing homeowners with not only beautiful and durable outdoor living solutions but also products that help enhance the safety of their outdoor spaces by adding an extra layer of protection against fire hazards.

"TimberTech is not just leading but revolutionizing the decking industry through innovation," said Jonathan Skelly, President of Residential and Commercial for AZEK. "These fire designations underscore our relentless pursuit to not only meet but to exceed fire safety standards. Considering the staggering number of over 46 million homes across 70,000 U.S. communities at risk from the impacts of wildfire, our comprehensive portfolio can help consumers harden their homes to reduce risk and increase resistance to heat, flames, and embers typical of most wildfires."

In addition to the new Ignition Resistant designation, TimberTech's Vintage and Landmark Collections hold a Class A Flame Spread Rating. Class A is the best rating available and indicates a material is in the highest range of resistance to flames. This means that in a fire, flames will spread slower across the deck surface. Class A Flame Spread Rated decking will resist catching fire and will not readily contribute to the spread of flames. TimberTech's Advanced PVC Decking also meets Wildland Urban Interface (WUI) compliance standards. Local building codes in WUI zones mandate fire-resistant materials for construction projects, including decks. WUI-Compliant materials resist flame spread and catching fire due to flying embers.

"The significance of these ratings cannot be overstated, especially for homeowners like me living in California and those living in other areas prone to wildfires or those simply seeking to enhance the safety of their homes," said Sam Toole, Chief Marketing Officer for AZEK. "No other decking matches the beauty or performance of our Vintage and Landmark Collections and features top-rated fire resistance."

TimberTech's recently introduced Aluminum Framing product pairs perfectly with Advanced PVC decking. Because it is made of aluminum, it is particularly well-suited for areas prone to fires as compared to wood, enabling TimberTech to provide homeowners with a comprehensive wood alternative decking and framing solution.
