When you purchase upvc profile double hung  window 002-2, you purchase directly from the factory. PVC double hung windows combine classic appearance with modern performance. Unlike casement windows, they do not swing inward or outward, saving interior and exterior space. The dual movable sashes enhance air circulation and safety. Made from durable PVC, these windows resist rot, rust, and fading while providing excellent thermal and acoustic insulation. Their smooth surface allows easy cleaning and minimal maintenance throughout long-term use. 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

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

VC sliding window is a modern, space-efficient window system widely used in residential and commercial buildings. Manufactured from polyvinyl chloride (PVC), this type of window combines durability, energy efficiency, and aesthetic appeal. The sliding mechanism operates horizontally along a track, making it ideal for areas with limited interior or exterior space where traditional casement windows might be obstructed. PVC sliding windows are known for their low maintenance requirements, excellent insulation properties, and resistance to moisture, termites, and corrosion. The multi-chambered profile enhances thermal and sound insulation, making them suitable for all climates. The double-glazed glass option further improves energy performance by reducing heat transfer and outside noise. 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
