Multi-chamber thermal insulation, lead-free UV stabilization, and precision custom fabrication for high-efficiency architectural projects worldwide.
High-Efficiency uPVC Fenestration for Green Buildings
Achieve Passive House standards with engineered U-values as low as 0.8 W/m²K, certified structural steel cores, and long-term weathering endurance.
As global energy efficiency directives tighten across North America, Europe, the Middle East, and Asia-Pacific, commercial project managers, real estate developers, and glazing contractors are re-evaluating their building envelope specifications. A high-performance UPVC Profile Window delivers an unmatched combination of low thermal conductivity, high sound transmission loss, and immunity to atmospheric corrosion—making it a preferred material choice for modern residential and commercial developments.
Unplasticized Polyvinyl Chloride (uPVC) is fundamentally a non-conductive polymer formulation. Unlike standard metals, a multi-chamber UPVC profile window structure traps stagnant air pockets within dedicated internal chambers. When engineered with galvanized steel reinforcement liners, the resulting profile delivers structural load capacity capable of resisting high wind pressures (up to 5,000 Pa) while keeping overall frame thermal transmittance (Uf values) between 0.9 and 1.3 W/m²K.
At Doorreme Aluminum Industry Co., Ltd., our engineering team formulates profiles using premium lead-free Calcium-Zinc (Ca-Zn) eco-stabilizers and high-concentration Titanium Dioxide (TiO₂) pigments. This prevents yellowing, surface chalking, and brittle fracture even in extreme solar irradiance environments like coastal regions, tropical humidity, or high-altitude alpine climates.
Doorreme manufactures custom-built UPVC profile window systems tailored to exact architectural shop drawings, structural opening requirements, and local thermal insulation codes.
Our flagship European-standard system featuring a 70mm or 80mm depth profile. Equipped with perimeter multi-point locking gear, EPDM triple gasket compression seals, and German Roto/Siegenia hardware integration. Designed for maximum water tightness and severe wind load resistance.
Specially engineered for large structural openings and balcony partitions where smooth glide performance is paramount. Features embedded 1.5mm–2.0mm steel liner channels, heavy-duty tandem stainless steel rollers, anti-lift safety blocks, and optional integrated SS304 mesh screens.
Designed for bespoke architectural designs requiring curved arches, triangular gables, or fixed picture frame combinations. Thermal profile bending technology ensures structural steel integrity is maintained across complex radiuses while retaining factory thermal sealant bonds.
Compare standard parameters across our UPVC profile window series. All specifications can be customized based on your structural calculations and project requirements.
| Profile System | Frame Depth | Chamber Count | Wall Thickness | Thermal Value (Uf) | Glazing Thickness Range | Acoustic Rating |
|---|---|---|---|---|---|---|
| 60 Series Casement / Awning | 60 mm | 3 Chambers | 2.5 mm (Class B) | 1.7 – 1.9 W/m²K | 5 mm – 24 mm | STC 32 – 35 dB |
| 70 Series High-Efficiency Tilt-Turn | 70 mm | 5 Chambers | 2.8 mm (Class A) | 1.2 – 1.4 W/m²K | 24 mm – 40 mm (Triple) | STC 38 – 42 dB |
| 80 Series Passive House System | 80 mm | 6 Chambers | 3.0 mm (Class A) | 0.9 – 1.1 W/m²K | 32 mm – 48 mm (Triple Low-E) | STC 42 – 46 dB |
| 88 Series Heavy-Duty Sliding | 88 mm | 3 Chambers + Steel Liner | 2.8 mm (Class A) | 1.8 – 2.1 W/m²K | 5 mm – 28 mm | STC 30 – 34 dB |
| Laminated Woodgrain UPVC System | 70 / 80 mm | 5 Chambers | 2.8 mm (Class A) | 1.2 – 1.3 W/m²K | 24 mm – 40 mm | STC 38 – 44 dB |
The global market for UPVC profile windows is rapidly shifting. Understanding these technological macro-trends helps procurement managers mitigate supply chain risks and specify future-proof products.
Tightening energy conservation building codes (such as EU EPBD directives and North American Energy Star V8.0) demand overall window U-factors below 1.0 W/m²K. 6-chamber and 7-chamber UPVC profile designs filled with polyurethane thermal foam insulation are becoming mandatory for low-energy housing projects.
Leading environmental regulatory authorities strictly prohibit lead-stabilized polymer formulations. Global buyers now insist on 100% lead-free Ca-Zn stabilized uPVC compounds. Modern profiles also integrate co-extruded recycled internal cores (PIR/PCR uPVC) surrounded by pristine virgin outer surface layers, balancing sustainability with immaculate surface aesthetics.
“High-Efficiency Fenestration Engineered for Tomorrow’s Carbon Standards.”
We align our material formulation, extrusion dies, and structural engineering to ensure your project complies with local energy regulations while maintaining competitive container-load pricing.
Historical limitations of plain white plastic windows are gone. Today's commercial developments mandate durable architectural finishes—such as German Renolit / Hornschuch high-weatherability foils, PMMA acryl-color co-extrusion, and metallic surface textures—allowing UPVC profile windows to match modern dark bronze, anthracite grey, or natural timber aesthetics.
Modern procurement favors concealed tilt-turn hinges, multi-point burglar-resistant locking hardware (PAS 24 / RC2 security class), and smart sensor integration for automated building management systems (BMS), driving higher safety and operational efficiency.
Established in 2004 in Foshan, China's premier building material manufacturing hub, Doorreme Aluminum Industry Co., Ltd. has evolved into a global leader in custom window, door, and architectural facade production.
Operating from an expansive 123,000 m² modern manufacturing facility staffed by over 800 skilled workers and engineering professionals, we have delivered tailored fenestration orders to projects across 140+ countries and regions. Our manufacturing rigor is driven by advanced German extrusion tooling, automated CNC cutting and welding centers, and an in-house quality control testing laboratory.
We eliminate technical discrepancies and import risks through a structured, drawing-verified manufacturing protocol.
Submit your architectural drawings, elevation schedules, or Bill of Quantities (BOQ). Our engineering desk reviews wind load criteria, opening sizes, and local building code constraints.
Select UPVC profile wall thickness, chamber count, foil lamination color, glass build-up (e.g. Low-E triple glazing), and hardware brand (German Roto or premium domestic hardware).
We issue full CAD shop drawings detailing profile cross-sections, steel core dimensions, drainage path mechanics, and anchor fixing points for client sign-off before production starts.
Fabrication begins under strict ISO 9001 quality protocols. Every finished window unit undergoes corner weld break testing, water penetration testing, protective film application, and export crate loading.
