In America,double hung vinyl windows is popular for home and commercial buildings to save space. Offering superior ventilation control compared to single hung windows, PVC double hung windows allow both upper and lower sashes to operate independently. The tilt-in design simplifies glass cleaning and maintenance. PVC frames deliver outstanding durability, resisting moisture, insects, and extreme weather conditions. With excellent insulation performance, these windows improve energy efficiency while requiring far less upkeep than traditional wooden window systems. series: 82 series PVC color : white opening style: Double Hung Glass: 3mm+12A+3mm clear tempered glass Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.21 Visible Transmittance: 0.41 Air Leakage: 0.15

We export sash window to the USA all the way. PVC double hung windows are ideal for residential and commercial applications where durability and ease of use are essential. Unlike sliding windows, they provide balanced airflow and improved safety through dual operable sashes. PVC material ensures long-term stability, resistance to corrosion, and low thermal conductivity. Easy-to-clean surfaces and no need for repainting make them a cost-effective, low-maintenance window solution. series: 82 series PVC Color : white opening style: Double Hung Glass: 3mm+12A+3mm clear tempered glass Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.21 Visible Transmittance: 0.41 Air Leakage: 0.15

Adopt upvc or pvc frame for push up window to save building cost. Compared to fixed or awning windows, PVC double hung windows offer flexible ventilation and enhanced user convenience. Both sashes can tilt inward, allowing effortless cleaning from indoors. PVC profiles provide excellent resistance to moisture, UV rays, and temperature changes, preventing warping and discoloration. With strong insulation and soundproofing performance, these windows deliver lasting comfort while minimizing maintenance requirements. series: 82 series PVC color : white opening style: Double Hung Glass: 3mm+12A+3mm clear tempered glass Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.21 Visible Transmittance: 0.41 Air Leakage: 0.15

Xiamen KDSBuilding’s PVC/UPVC sliding windows represent a perfect blend of modern aesthetics, energy efficiency, and durability, making them an ideal choice for both residential and commercial projects. Fabricated using premium-grade unplasticized polyvinyl chloride (UPVC), these windows undergo a meticulous multi-stage manufacturing process to ensure exceptional performance. It begins with the precision extrusion of UPVC profiles, which are then internally reinforced with galvanized steel to enhance structural strength and prevent warping over time. The profiles are cut with advanced CNC machines for exact dimensions, followed by corner welding or mechanical joining to achieve airtight, seamless frames. High-quality EPDM gaskets are inserted to guarantee superior sealing, while double or triple glazing units are fitted to maximize thermal insulation and noise reduction. The sliding mechanism incorporates smooth, corrosion-resistant stainless-steel rollers and a multi-point locking system, ensuring effortless operation and enhanced security. series: 72 series PVC opening style: Top sliding and bottom fixed Color: White Glass: 5mm+9A+5mm clear tempered glass Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23
