Custom White UPVC Double Glazed Sliding Window delivers superior energy efficiency and low-maintenance performance for residential and light commercial buildings, solving a common homeowner dilemma: traditional aluminum windows conduct heat excessively, while wood frames require constant upkeep. This innovative system combines lead-free UPVC profiles with high-performance double glazing to achieve U-values as low as 0.8 W/(m²·K), reducing heating costs by up to 35% compared to single-pane aluminum windows. The pristine white finish maintains color integrity for decades, eliminating repainting needs, while the sliding mechanism operates effortlessly even after 10,000 cycles—making it ideal for bedrooms, living rooms, and home offices where comfort and convenience are priorities.
Exceptional Thermal Performance: Multi-chambered UPVC profiles with 24mm warm-edge spacer bars and double-glazed units (4mm tempered glass + 16mm argon fill + 4mm low-e glass) achieve UW values as low as 0.8 W/(m²·K), qualifying for passive house standards.
Durable White Finish: UV-stabilized vinyl compound retains whiteness with less than 5% fading after 15 years of direct sunlight exposure, tested to ISO 4892-3 standards. The smooth surface resists dirt accumulation and requires minimal cleaning.
Smooth Sliding Operation: Precision stainless steel rollers with ball-bearing mechanisms require <8N force for operation, with anti-jump tracks and height-adjustable components ensuring stable performance over time.
Enhanced Security: Multi-point locking system with 10mm mushroom bolts and reinforced steel cores in critical sections achieves RC2 security rating, resisting forced entry attempts for 5+ minutes under EN 1627 standards.
Residential Renovations: Older homes benefit from easy retrofitting that reduces heat loss by 60% compared to original single-pane windows, with white finish matching classic and modern architectural styles.
Passive Houses: Achieves the stringent thermal requirements of passive building standards, with air leakage rates below 0.6 ACH@50Pa when properly installed.
Noise-Sensitive Areas: Urban apartments and homes near transportation routes utilize the 32 dB acoustic insulation (STC 32) to reduce traffic and neighborhood noise.
Coastal Properties: Salt-resistant hardware and UV-stabilized profiles withstand marine environments, outperforming aluminum windows in corrosion resistance.
Q: How does UPVC compare to aluminum in thermal performance?
A: UPVC profiles have 500% lower thermal conductivity than aluminum (0.16 W/(m·K) vs. 205 W/(m·K)), eliminating cold bridging without needing thermal breaks. This translates to 30% lower heating costs in temperate climates.
Q: Can the white color be customized?
A: While white is our standard, we offer over 20 RAL colors with the same UV-stabilized formula. Custom colors include wood grain foils that match the thermal performance of solid white profiles.
Q: What is the expected lifespan of the sliding components?
A: The stainless steel rollers and reinforced tracks are warranted for 10 years, with typical service life exceeding 20 years with minimal maintenance. We provide replacement kits for easy component renewal.
Q: How does the window perform in extreme temperatures?
A: The UPVC formulation remains stable from -40°C to 70°C, maintaining dimensional integrity and operation smoothness. In cold climates, condensation is reduced by 75% compared to aluminum windows.
