China Best Aluminium Frameless Windows Manufacturer & Exporters

Unlike traditional slimline windows which still feature visible 20mm–50mm perimeter aluminium sashes, a true frameless structural glass window conceals its structural outer aluminum frame entirely within the ceiling soffit, side walls, and finished floor slab. Only a vertical silicone junction joint (or ultra-slim 12mm interlock line) remains visible to the naked eye, offering absolute maximum transparency without sacrificing structural load capability.

Novax utilizes an engineered continuous sub-sill drainage channel system with integrated pressure-equalization chambers. Any rainwater hitting the outer glass face is channeled down through concealed micro-gaps into an extruded aluminum drainage pan beneath the finished floor level. From there, water flows out via heavy-duty stainless steel one-way valves. Coupled with multi-layered EPDM acoustic sealing gaskets, our systems successfully pass ASTM E547 water infiltration tests up to 700 Pa.

Yes. Novax offers certified hurricane impact-rated frameless sliding and fixed window configurations engineered for Florida Building Code (FBC) HVHZ compliance. These configurations feature heavy-wall AA6063-T6 aluminum extrusions combined with laminated structural glass containing 1.52mm or 2.28mm Kuraray SentryGlas® (SGP) interlayers. They are rigorously tested under TAS 201 (Large Missile Impact), TAS 202 (Structural Uniform Static Air Pressure), and TAS 203 (Cyclic Wind Pressure).

Our custom heavy-duty bottom-roller carriages and heavy stainless steel tracks can accommodate individual glass panel areas up to 18 square meters (e.g., 6.0 meters high by 3.0 meters wide) with single sash weights up to 1,200 kg (2,640 lbs). Precision stainless-steel tandem rollers with ceramic bearings ensure manual pushing force remains under 20 Newtons even for giant sashes.

Novax executes a 5-stage export packing protocol: 1) Protective PE film applied across all aluminum anodized surfaces; 2) Corner guard shock absorption cushions; 3) Vacuum-sealed moisture barrier wrap around glass sashes; 4) Fully enclosed ISPM-15 compliant fumigated plywood crates; 5) Steel-strapped internal bracing within 40ft High Cube containers to prevent dynamic sea transit movement.

For coastal deployments within 500 meters of salt water, Novax offers 25-micron class-1 anodized aluminum finishes or Qualicoat Class 2 certified Fluorocarbon PVDF liquid paint systems (70% Kynar 500 resin base). These finishes pass 3,000+ hours of continuous ASTM B117 salt spray testing with zero blistering, pitting, or color fading.

We utilize imported German Polyamide PA66-GF25 structural thermal breaks (reinforced with 25% glass fiber) measuring up to 34mm in depth. Combined with warm-edge spacer bars (Swisspacer / Technoform) and low-E triple pane glass filled with Argon gas, we achieve system U-values down to 0.85 W/m²K, making our windows suitable for northern USA, Canada, and European winter climates.

Yes, our in-house team of 72 R&D engineers generates comprehensive AutoCAD installation shop drawings, 3D Revit BIM models, wind pressure structural calculation packages, and thermal simulation reports for architectural submission and local building authority approval before manufacturing begins.
