Product DescriptionDouble Tempered Low-E Glass UPVC Vinyl Windows1. Core StructureDouble Tempered Low-E Glass UPVC Vinyl Windows are high-performance energy-saving windows integrating double-layer tempered glass, low-emissivity (Low-E) coating, and UPVC (unplasticized polyvinyl chloride) profiles.Their core structure includes:Double Tempered Glass:The two panes of glass in the Double Glazed PVC Sliding Windows are tempered, providing more than five times the impact resistance of ordinary glass. When broken, they shatter into blunt-angled fragments, ensuring high safety.Low-E Coating:Multiple layers of metal oxides (such as silver) are coated on the glass surface, forming a film that is highly transparent to visible light and highly reflective of mid- and far-infrared rays, effectively blocking heat transfer.UPVC Profile:Made primarily of PVC resin with added stabilizers, impact-resistant agents, and other additives, it is manufactured through extrusion molding. The internal design features a multi-chamber structure (typically 3-7 chambers) to enhance thermal insulation performance.
2. Structural Features: Function-Oriented Precision DesignDouble Tempered Glass and Insulating LayerThe gap between the two panes of glass is typically 12-16mm, filled with inert gases such as argon to reduce heat transfer efficiency. A desiccant is placed inside the insulating layer to prevent condensation.Data Comparison: The heat transfer coefficient (U-value) of ordinary single-pane glass is 5.8 W/(m²·K), while the U-value of double-tempered insulating glass can be reduced to 1.8-2.5 W/(m²·K), and the U-value of Low-E insulating glass is further reduced to 1.3-1.8 W/(m²·K).Multi-Cavity Design of UPVC ProfilesPVC Windows typically have a profile width of 60-80mm. The interior is divided into multiple independent chambers by thermal break strips, forming an air insulation layer. Combined with a 1.2-2.0mm galvanized steel lining, the wind pressure resistance reaches over 700Pa (equivalent to a category 12 typhoon).Case Study: A certain 65-series UPVC window features a 5-chamber design, achieving a U-value as low as 1.3 W/(m²·K), resulting in 40% energy savings compared to ordinary Aluminum Alloy Windows.Concealed Drainage and Sealing System: Concealed drainage holes are integrated at the bottom of the window frame, combined with a sloping design to ensure rapid rainwater drainage and prevent leakage.EPDM rubber sealing strips are used to achieve multi-layered sealing, achieving an airtightness level of 8 (the highest level) and a watertightness level of 6.
3. Material Advantages: Dual Guarantee of Performance and Environmental ProtectionUPVC ProfilesDurability: The UV-resistant coating has passed a 6000-hour salt spray test, suitable for coastal or high-humidity areas, with a service life exceeding 20 years.Environmental Protection: 100% recyclable, with 60% lower carbon emissions over its lifecycle than aluminum alloy windows, meeting green building standards (such as LEED and Green Star).Maintenance Costs: No painting or anti-corrosion treatment required; sealing strips need to be replaced every 5 years (cost approximately 50 RMB per window).Double-Tempered Low-E GlassEnergy Saving: Reduces indoor heat loss by over 30% in winter and blocks over 70% of solar radiation heat in summer, reducing air conditioning energy consumption.Safety: Tempered glass has 5 times the impact resistance of ordinary glass, and the Low-E coating blocks over 99% of UV rays, protecting indoor furniture from fading.Sound Insulation: The double-glazed structure combined with the Low-E coating reduces noise by 30-40 decibels, suitable for buildings near airports or busy commercial areas.4. Applicable Buildings: Flexibility Covering All ScenariosResidential SectorVillas/Townhouses: Large window sizes (maximum 3m x 2.5m) paired with stone or wood exterior walls create a classic European style.High-Rise Apartments: Small to medium-sized window sizes (1.2m x 1.5m) combined with double-layered tempered glass meet wind pressure resistance and fire protection requirements (such as the Australian BCA standard).Commercial BuildingsHotels/Clubs: Narrow frame design increases the glass ratio, enhancing indoor lighting and visual transparency. Schools/Hospitals: Antibacterial UPVC surface treatment inhibits bacterial growth; child safety locks are optional (opening limit ≤100mm).Special Environments:Coastal Areas: Fire-resistant option tested to AS1530.8.1, capable of withstanding BAL-40 bushfires (compliant with AS3959-2009 standard).Cold Regions: Triple-glazed, double-cavity structure (Ug value ≤0.6 W/(m²·K)) with UPVC profiles, reducing winter energy consumption by 35%.
5. Selection Guide: Five Steps to Match NeedsSize and Opening Method:Custom PVC Windows: Choose standard (width ≤1.5m) or custom (width ≤3m) windows based on opening size, allowing a 5-10mm installation gap.Opening methods include casement, awning, and sliding. Casement windows offer the highest ventilation efficiency, while sliding windows save space.Glass ConfigurationEnergy Saving Requirements: Select Low-E insulated glass with argon gas filling; U-value ≤ 1.5 W/(m²·K).Sound Insulation Requirements: Select laminated glass (6mm PVB + 12mm + 6mm), improving noise reduction by 10 decibels.Safety Requirements: Tempered glass is mandatory for large areas or high-rise buildings.Hardware SystemHinges must be AS2047 certified, with a load-bearing capacity ≥ 80kg/pane and over 50,000 opening/closing cycles.Handles can be equipped with a multi-point locking system (e.g., 12-point locking), improving airtightness by 30%.Color and Surface TreatmentStandard colors are white/beige; custom colors (e.g., dark gray, coffee) are available from the RAL color chart.Surface treatments include coating (low cost) and co-extrusion (scratch-resistant); co-extrusion extends product life by 5 years.Certifications and After-Sales ServiceProducts are AS2047 and AS1288 certified; please check the WERS (Window Energy Efficiency Rating Scheme) label.Prioritize suppliers that offer 10 years of after-sales service and 5 years of warranty to reduce long-term maintenance costs.The file is encrypted.
