Certified Quality Compliance

The CE Mark Advantage (EN 14351-1 Standard)

Our CE Certification guarantees compliance with European Union Construction Products Regulation (CPR No 305/2011). Under EN 14351-1, Novax aluminium sash windows undergo rigorous third-party testing for air permeability (EN 12207 Class 4), watertightness (EN 12208 Class E1050), wind load resistance (EN 12210 Class C5), thermal transmittance (EN ISO 10077-2 U-values down to 0.8 W/m²K), and acoustic damping (EN ISO 717-1 up to 45 dB).

Next-Gen Aluminium Sash Windows: Technical Roadmap & Engineering Horizon

The evolution of vertical sliding sash windows has transitioned from traditional timber aesthetics to advanced structural metallurgy. Modern architectural requirements demand extreme thermal isolation, massive glass daylight ratios, and seamless structural integration into zero-energy building envelopes.

Vacuum Insulated Glass (VIG) Synergy

Incorporating 0.3mm micro-vacuum gaps into double and triple sash units allows thermal U-factors as low as U=0.4 W/m²K—outperforming solid brick walls while eliminating sash weight penalties on counter-balance mechanisms.

Smart Motorized Vertical Actuation

Embedded brushless linear actuators coupled with IoT wind/rain sensors enabling automated night purge ventilation, automated building management system (BMS) integration, and touchless smartphone UI control.

Circular Economy Aluminum Metallurgy

Utilizing Hydro CIRCAL® ultra-low-carbon aluminum profiles containing ≥75% post-consumer scrap metal, reducing embodied carbon footprints to under 2.3 kg CO2 per kg of aluminum extruded.

Macro Industry Solutions: Engineered for Extreme Global Geographies

Architectural envelope demands vary drastically across continents. Novax custom-engineers aluminium sash windows to satisfy stringent regional structural engineering codes and micro-climatic stress factors.

Coastal Hurricane & Typhoon Zones (Caribbean & Florida HVHZ)

Designed to meet TAS 201/202/203 and ASTM E1886/E1996 large missile impact criteria. Features heavy-wall 6063-T6 extruded aluminum profiles (2.0mm wall thickness), multi-layer SentryGlas® (SGP) laminated glass interlayers, and high-strength anti-lift sash locks. Resists sustained wind pressure loads exceeding ±70 PSF.

Cold Climate Passive House Applications (Nordic & N. America)

Engineered with polyamide thermal break channels (PA66-GF25, 24mm to 34mm depth) inserted between inner and outer aluminum extrusions to break isothermal bridge lines. Paired with triple argon-filled double Low-E glass units, eliminating interior sash condensation down to ambient external temperatures of -35°C.

High-Density Urban Acoustic Dampening

Urban inner-city developments require defense against broad-band noise pollution (traffic, aviation, rail). Novax asymmetrical double glazing (e.g., 8.76mm laminated + 16mm Argon gap + 6mm toughened glass) achieves acoustic dampening ratings up to Rw 43dB, protecting occupant wellness in luxury high-rises.

Heritage & Luxury Commercial Restoration

Combining Victorian aesthetic profiles, traditional Georgian bar layouts, and tilt-in sash functionality for effortless exterior glass cleaning from the interior. Provides historic district aesthetics with state-of-the-art aluminum durability and security ratings (PAS 24 / EN 1627 RC2).

China Industry 4.0: Production Line Rigor & Operational Precision

Within our 40,000 square meter smart factory, Novax deploys digitalized production control systems across every phase of fabrication. From 6063-T6 raw aluminum billet inspection to automated double-glazed unit (DGU) sealing, our zero-defect policy guarantees operational efficiency and delivery speed for global enterprise clients.

Frequently Asked Technical & Procurement Questions

Architectural engineering and compliance answers curated for search intent, specifying engineers, and global procurement officers.

What European Standards (EN) are covered under your CE Certification for Aluminium Sash Windows?
Our CE certification complies directly with EN 14351-1:2006+A2:2016 for windows and external pedestrian doorsets. Specific performance test standards include EN 12207 for Air Permeability (achieving Class 4), EN 12208 for Watertightness (achieving Class E1050), EN 12210 for Wind Load Resistance (Class C5/B5), EN ISO 10077-2 for Thermal Transmittance performance, and EN ISO 717-1 for Sound Insulation. Complete Factory Production Control (FPC) documentation and Declaration of Performance (DoP) certificates are supplied with every order shipment.
How do thermal break aluminium sash windows compare to uninsulated aluminium or uPVC profiles?
Uninsulated aluminium features high thermal conductivity (K-value ~200 W/mK), causing thermal bridging, interior sweating, and energy loss. Novax thermal break aluminium windows utilize structural Polyamide PA66-GF25 (reinforced with 25% glass fiber) to separate the interior and exterior aluminum profiles, reducing conductivity to ~0.3 W/mK. Compared to uPVC, thermal break aluminium offers superior structural frame strength, thinner sightlines, higher dynamic wind load handling, longer service life (>50 years vs 20 years), and zero UV degradation or yellowing.
What counterbalance mechanism options are available for large heavy-weight sash sashes?
Novax offers three distinct counterbalance engineering systems depending on sash size and glass mass: 1) Heavy-duty constant-force spring balancers (rated up to 50 kg per sash sash); 2) High-precision adjustable spiral balancers for fine-tuned tension adjustment during multi-story installation; and 3) Concealed motorized electrical linear actuators for commercial smart-building integration. All counterbalances undergo 20,000-cycle mechanical fatigue lifecycle testing without force degradation.
Can your aluminium sash windows meet Florida HVHZ hurricane impact codes?
Yes. We engineering customized hurricane impact series incorporating heavy-wall 6063-T6 aluminum profiles (up to 3.0mm wall thickness at high-stress mullions) paired with laminated impact glass (featuring SentryGlas® SGP or Solutia Vanceva PVB interlayers). Systems are designed and tested to withstand TAS 201 (Large Missile Impact), TAS 202 (Uniform Static Air Pressure), and TAS 203 (Cyclic Wind Pressure Loading) up to ±70 PSF design pressures.
What is the typical lead time and Minimum Order Quantity (MOQ) for enterprise B2B export contracts?
Our standard production lead time is 25 to 35 calendar days following shop drawing approval and sample confirmation. For custom extrusion profiles requiring new dies, add 14 days for tooling fabrication and initial sample extrusion testing. Our standard MOQ is 50 square meters for standard powder-coated colors (RAL 9016, RAL 7016, RAL 9005) and 200 square meters for custom anodized, PVDF, or timber-grain finish profiles.
