Aluminium Windows and Doors Wholesaler in China: Aluminum Window Frame, Double & Triple Glazed Specs and Pricing
Aluminium windows and doors package on a residential villa: thermally broken aluminum window frame series, sliding glass door and glazed entrance door supplied from one extrusion platform in Foshan, China.
Buying aluminium windows and doors at wholesale volume from China is a numbers exercise: profile wall thickness, thermal break strip width, glass build, test class, FOB price band and container loading count decide the landed cost per square meter. This page publishes the working data of a Foshan-based wholesaler program – window and door price ladders by configuration, aluminum window frame alloy and series data, measured U-values for double glazed and triple glazed aluminium windows, certification references, MOQ, lead time and a completed 48-townhouse project cost breakdown – so a distributor, builder or project buyer can run the comparison before requesting a quotation.
Wholesale Pricing for Windows and Doors from China
A wholesaler quote for windows and doors splits into two price families. Windows are priced by frame series plus glass build; doors carry a hardware surcharge because hinges, multi-point locks and rollers cost more than window handles. The tables below are FOB Foshan reference bands for anodized or powder coated thermally broken frames, standard colors, ex-works packing in plywood crates. For sliding-window-specific numbers see the sliding windows wholesale price list.

Aluminum Window Frame Systems: Alloy, Wall Thickness and Thermal Break
The aluminum window frame determines 60-70% of a finished window’s performance: structural stiffness comes from alloy temper and wall thickness; thermal performance comes from the polyamide strip width and cavity design. ROGENILAN extrudes in Foshan on 6063-series billets with in-house aging ovens, so temper is verified per batch rather than per certificate copy. Casement-specific frame data is also published on the casement windows factory page.

Double Glazed Aluminium Windows: Standard Build Data
Double glazed aluminium windows remain the volume product of any wholesale program: roughly 80% of export orders specify a two-pane IGU. The performance spread inside ‘double glazing’ is wide, so every quotation should state glass make-up, cavity gas, spacer type and coating position rather than just ‘double glazed’.

For street-facing bedrooms and hotel projects, specify the acoustic laminated builds: moving from Rw 31 to Rw 39 dB cuts perceived traffic loudness by roughly half. The surcharge is US$18-26/m2 of glass – cheaper than any after-installation retrofit.
Triple Glazed Aluminium Windows vs Double Glazed: Measured Comparison
Triple glazed aluminium windows add one pane, one cavity and roughly 10 kg/m2 of glass weight. The upgrade is justified by climate and energy price, not by catalogue language. The comparison below uses the same 70-series casement frame so the glass is the only variable.

When the Triple Glazed Upgrade Pays Back
Heating-dominated climates (Canada, northern US, Scandinavia, northern China, alpine Australia/New Zealand): at Uw 1.4 vs 1.8 and 3,500 heating degree days, a 200 m2 house glazing package saves roughly 1,100-1,500 kWh of heat per year – a 6-9 year payback at US$0.12/kWh.
Passive-house and near-zero-energy projects: triple glazing with Uw <= 1.0 (90 series, 34 mm strip) is a certification prerequisite, not an option.
Cold-side condensation control: inner pane surface temperature stays 4-6 C higher with triple build, removing condensation at -10 C outdoor / 50% indoor humidity where double glazed low-e starts to mist.
Skip the upgrade for cooling-dominated tropical projects: spend the budget on solar-control low-e (SHGC <= 0.35) double glazing instead - lower g-value beats lower U-value when the load is solar gain.

Installation Tolerances, Sealing and Site Data
Opening Tolerances and Fixing
Structural opening: frame size + 15-20 mm perimeter gap; opening must be plumb within 3 mm per meter.
Fixing: galvanized steel brackets or frame anchors at <= 600 mm centers, maximum 150 mm from corners; large sliding and folding doors fixed at <= 400 mm centers on the head track.
Sill support: continuous setting blocks at quarter points, never point-supported only at corners; sill slope minimum 5 degrees with end-dammed drainage.
Three-Layer Waterproofing Sequence
Layer 1 (interior air seal): low-expansion PU foam or pre-compressed tape, tooled flat – this layer carries the airtightness class.
Layer 2 (drainage plane): butyl flashing tape lapped sill-to-jamb-to-head with sill pan; never reverse-lap the head flashing.
Layer 3 (exterior weather seal): neutral-cure silicone (ASTM C920 Class 25) 8-10 mm joint, backer rod at 50% compression.
Commissioning: operate every sash 20 cycles, adjust hinge friction and lock keeps, water-test one random unit per elevation with a hose at 0.2 MPa for 15 minutes.
