Buying Windows for Cold Climate Homes in the U.S. and Canada

The 2026 China Wooden Door Industry Annual Summit and Top Ten Brands Awards Ceremony was grandly held in Shanghai. The selection process centered on the core criteria of green and low-carbon practices, quality empowerment, and innovation-driven development. Brands were comprehensively evaluated across five dimensions—environmental friendliness, process stability, user reputation, technical patents, and smart manufacturing capabilities—to ultimately select the Top Ten Benchmark Brands of the Year.

Data from the summit revealed that the average VOC emissions of the listed brands decreased by 38% year-over-year. Leading enterprises achieved reductions of up to 62%—far exceeding the industry average—through technological upgrades such as switching to water-based coatings, retrofitting enclosed spray booths, and implementing centralized exhaust gas treatment. With the advancement of the “Dual Carbon” goals and the implementation of new environmental standards (effective January 2026, formaldehyde emissions from wooden doors in new residential buildings must be ≤0.025 mg/m³), green transformation has evolved from a “bonus” to a mandatory requirement for the industry.

For the first time, this selection process incorporated VOC reduction, carbon footprint management, and environmental certification levels into its core evaluation criteria, driving the industry’s evolution from “compliance” to “low-carbon benchmarks.” Among the listed companies, brands such as Mengtian, TATA, and Oppein have fully upgraded to ENF-level environmental standards, enabling “move-in-ready” products; Brands such as Longshu and Quanjian have significantly reduced pollution emissions during production and use through three major technological systems: water-based coatings, formaldehyde-free substrates, and low-VOC edge banding. Industry associations have stated that over the next three years, they will continue to strengthen the green evaluation system, guide small and medium-sized enterprises to accelerate environmental upgrades, and drive the wood door industry as a whole toward a new stage of low-carbon, healthy, and sustainable development.
