We are proud to announce that KDSBuilding has officially obtained the NFRC Label Certification, marking a major milestone in our continuous commitment to high-performance aluminum and PVC windows and doors. This certification represents an important recognition of our product quality and energy efficiency standards in the international building industry.

The NFRC (National Fenestration Rating Council) label provides verified performance data such as U-factor, Solar Heat Gain Coefficient (SHGC), Visible Transmittance (VT), and air leakage performance. With this certification, our products are independently tested and rated, giving architects, contractors, and developers clear and reliable information for building design and compliance.

This achievement reflects our strong focus on advanced manufacturing and product development. By using thermal break aluminum systems,multi-cavity PVC profile with high strengthen reinforcement steel, high-performance Low-E insulated glass, and precision production equipment, we ensure our windows and doors meet strict energy-saving requirements, especially for demanding markets such as the United States ,Canada and other countries.

With NFRC certification, KDSBuilding`s products become more competitive and widely accepted in global projects. It not only improves our ability to support residential and commercial developments, but also strengthens trust with international partners who require certified energy performance and reliable building solutions.

Looking forward, we will continue to invest in innovation and quality improvement to deliver even more efficient, durable, and sustainable window and door systems. Our goal is to help build smarter and greener buildings worldwide with certified performance and trusted quality.
