When procurement managers, facade consultants, and master architects evaluate an Architectural Aluminum Window System, they are not merely specifying glass frames—they are engineering the outer thermal, structural, and acoustic shield of a building facade. Unlike basic residential windows, an architectural-grade window system must balance vast structural glass spans, strict building energy codes, high wind-load deflection limits (L/175 or L/240), and refined aesthetic sightlines.
At Veltor Window & Door Co., Ltd., based in Nanhai District, Foshan, we bridge the gap between complex architectural intent and physical manufacturing reality. Utilizing heavy-duty 6063-T6 aluminum alloys, precision CNC hardware mortising, multi-chambered polyamide (PA66 GF25) thermal breaks, and structural EPDM triple-seal gaskets, our systems are built to perform reliably across extreme climates—from sub-zero North American winters to humid tropical coastal zones.
Explore five specialized system series tailored for high-rise commercial facades, luxury residential estates, coastal resorts, and urban institutional developments.
Engineered with a 75mm to 85mm frame depth and 24mm to 34mm PA66 polyamide insulating strips. Features heavy-duty friction stays, continuous EPDM weather-stripping, and hidden pressure-equalized drainage. Ideal for high-wind residential towers and luxury villas demanding superior airtightness.
System DetailsCombines inward side-hung opening for easy glass cleaning with top-tilt ventilation for draft-free micro-air exchange. Utilizes perimeter multi-point locking gear to clamp the sash tightly against dual EPDM gaskets, achieving exceptional security and sound dampening up to STC 42.
System DetailsDesigned for mid-to-high rise commercial buildings requiring continuous glass facades with integrated operable windows. Offers stick-built or unitized pre-assembled modules with structural silicone glazing (SSG) or pressure-plate framing, accommodating thermal movements and structural floor deflections.
System DetailsEngineered for floor-to-ceiling panoramic glass openings up to 3.5 meters in height per panel. The mechanical lift-and-slide mechanism lifts the 400kg sash off the weather seals during operation for effortless glides, then lowers and locks it onto double gaskets for total weather sealing when closed.
System DetailsDesigned for contemporary architectural trends prioritizing maximum natural light and ultra-narrow sightlines (interlock vertical sightline down to 18mm). Utilizes high-strength structural glazing adhesives to make the glass an integral structural component of the frame profile.

Insights for real estate developers, facade consultants, and general contractors navigating decarbonization, smart building automation, and extreme weather resilience.
Global carbon accounting standards (such as LEED v4.1 and BREEAM) are driving demand for low-embodied-carbon aluminum extrusions. Procurement directors now prioritize manufacturers utilizing hydroelectric-smelted 6063-T6 aluminum alloys and recycled post-consumer scrap. Veltor provides Environmental Product Declarations (EPDs) and raw material batch traceability to support green building compliance.
Energy performance requirements across North America (ASHRAE 90.1), Europe (EPBD directives), and Australia (NCC Section J) are mandating whole-window U-factors below 1.2 W/m²K. Modern architectural systems are shifting from double-pane glass to warm-edge, argon-filled triple-glazed units featuring dual Low-E coatings to satisfy net-zero energy building (NZEB) targets.
The convergence of window hardware with Building Management Systems (BMS) is rapidly accelerating. Automated motor chain actuators for high-level awning vents, concealed sensor wiring channels within window frames, and electrochromic dynamic tinting glass are increasingly requested for high-end commercial projects and intelligent luxury residences.
To counteract rising on-site installation labor costs and field quality risks, general contractors are shifting toward factory-glazed, fully assembled unitized window modules. Veltor’s factory-installed glazing, pre-calibrated locking mechanisms, and opening-tagged crating allow installation teams to hoist and anchor modules directly into building rough openings with minimal field adjustment.
How Veltor solves the structural, thermal, and sealing challenges of modern architectural facades through engineering precision.
Polyamide strips reinforced with 25% fiberglass offer identical thermal expansion coefficients to aluminum extrusions, preventing shear stresses, frame warping, or thermal seal failures across extreme temperature cycles.
Designed using kinetic pressure-equalization chambers. Exterior wind pressure is balanced inside the drainage cavity, eliminating the pressure differential that forces driving rain past weather gaskets.
High-grade Ethylene Propylene Diene Monomer (EPDM) vulcanized corner gaskets ensure long-term elasticity, resisting UV oxidation, ozone breakdown, and permanent compression set for decades.
Corner joints are mechanical-crimped with solid cast-aluminum corner keys and injected with two-component polyurethane corner adhesive (DUO-PUR) for ultimate frame shear strength and watertight seal integrity.
European groove standard multi-point locking gear (Siegenia / Roto / SOBINCO) is fully concealed inside the sash rebate, providing anti-burglary protection (RC2 / RC3 rating) and uniform seal compression.
Integration of specialized acoustic PVB and SentryGlas (SGP) interlayers dissipates sound wave energy across low and high frequencies, delivering whisper-quiet indoor environments near airports or main arteries.
Our Foshan manufacturing hub operates under strict ISO 9001 protocols, delivering complete transparency and rigorous quality control for international architectural projects.
Located in Nanhai, Foshan, we source prime-grade 6063-T6 aluminum extrusions directly from top smelters with full chemical composition certificates.
Automated double-head saws and 5-axis CNC machining centers route hardware mortises, hinge notches, and weep slots within ±0.2mm tolerance.
Every project undergoes 2D/3D CAD shop drawing modeling and structural load simulation before profile cutting begins.
We assemble every window frame, test hardware operation, measure diagonal squareness, verify glass seal tightness, and provide photo/video inspection reports prior to crating.

Architectural Aluminum Window Systems are engineered to satisfy rigid structural, thermal, and acoustic performance thresholds required by commercial building codes and modern luxury elevations. Unlike standard residential windows, architectural systems feature thicker structural profile walls (typically 1.8mm to 3.0mm 6063-T6 aluminum alloy), advanced polyamide PA66 GF25 thermal breaks, integrated structural glass pockets, multi-stage EPDM weather sealing gaskets, and hardware load-rated for oversized glass panels up to 400 kg per sash.
When integrated with multi-chamber thermal break profiles, Technoform PA66 polyamide insulating strips, triple-pane Low-E insulated glass units (IGUs), argon gas filling, and warm-edge spacers, VELTOR architectural window systems achieve total system U-factors down to 0.8 to 1.4 W/m²K (U-0.14 to U-0.25 BTU/h·ft²·°F). This meets and exceeds stringent international energy codes including Passive House, NFRC, and European Energy Efficiency Directives.
