Durabuilt’ s product offering has expanded significantly over the years and now includes PVC windows, aluminum-clad PVC systems, commercial aluminum glazing, and a comprehensive library of doors ranging from exterior and hollow metal to steel and specialty applications.
“ We’ ve always been a forward-thinking company,” Sunner explains.“ Today, we’ re in a position where we can provide a window or door solution for almost any project type – whether it’ s new construction or replacement, single-family, multi-family, highrise, or industrial. In the vast majority of cases, Durabuilt has a solution that meets both performance and design requirements.” One of the company’ s most recent innovations is its Delta Fiberglass Window
System, a luxury fiberglass product line developed to meet growing demands for larger openings, increased structural performance, and superior energy efficiency.
“ Fiberglass is the next leader in the window and door space,” Sunner says.“ In certain project types, it’ s becoming a requirement due to size, compliance, and performance standards. Delta is positioned as a premium solution, and we’ re seeing strong market adoption and growth as designers and builders look for higherperforming, more durable products.”
Sustainability and energy performance remain central to Durabuilt’ s innovation strategy. In 2025, the company was named ENERGY STAR Manufacturer of the Year, a recognition Sunner describes as a significant milestone.
