Thermal Break Aluminum Casement Doors
Architectural-grade inswing and outswing casement door systems engineered for extreme weather resistance, structural longevity, and thermal insulation.
Product System Overview
What are Thermal Break Aluminum Casement Doors?
Vexis Windows & Doors Co., Ltd. manufactures commercial and residential aluminum casement doors using high-strength 6063-T5/T6 virgin aluminum alloy extrusions. Built with side-hinged operational sashes, our doors open fully inward or outward to maximize ventilation and entry width.
Unlike conventional doors, our thermal break systems incorporate PA66 polyamide insulation strips that isolate the interior and exterior aluminum profiles. This creates a thermal barrier that reduces heat transfer, prevents interior condensation, and maintains energy efficiency across tropical, coastal, and cold climate zones.
Every unit is manufactured to order at our 30,000 m² Foshan production facility, featuring multi-layer EPDM sealing strips, 304 stainless steel heavy-duty hinges, double or triple tempered Low-E glass, and German multi-point locking mechanisms for maximum security.
System Variations
Casement Door Series for Global Projects
Explore specialized casement door configurations built to meet architectural specs, wind-load ratings, and thermal requirements.
Outswing Entrance & Patio Doors
Weatherproof exterior doors designed to resist driving rain and hurricane wind loads by pressing tighter against double-seal gaskets under outward pressure.
Thermal Break Inswing Doors
Inward opening configurations ideal for balconies and interior transitions, featuring low-threshold aluminum profiles for barrier-free access.
Ultra-Slim Sightline Doors
Minimalist frame design engineered for modern architectural projects, maximizing natural daylight while keeping high acoustic and thermal ratings.
Engineering Superiority
Core Performance Advantages
Tested profiles, premium components, and precision assembly deliver reliable long-term performance.
Superior Weatherproofing
Continuous multi-layer EPDM rubber gaskets combined with hidden drainage channels effectively prevent water penetration and air leakage even under severe rainstorms.
Thermal & Acoustic Barrier
PA66-GF25 thermal breaks combined with double/triple Low-E argon-filled tempered glass achieve U-values below 1.6 W/m²K and acoustic reduction up to 42 dB.
Multi-Point Security Locks
Equipped with heavy-duty 304 stainless steel gearboxes, shoot bolts, and anti-pry locking points to ensure high burglary resistance and perimeter tightness.
High Structural Integrity
Wall thickness up to 2.0mm-3.0mm made from 6063-T5 primary aluminum alloy withstands high wind pressures, making it suitable for high-rise or coastal installations.
Surface Treatment Options
Choose from AkzoNobel powder coating, anodizing, PVDF fluorocarbon spraying, or authentic Italian wood-grain heat transfer finishes resistant to UV fading and salt corrosion.
Full Opening & Low Threshold
Side-hinged design provides a 100% full clear opening area. Available with flush thermal barrier water-stop thresholds for seamless indoor-outdoor transitions.

Buyer Knowledge Base
Frequently Asked Questions
Common questions answered for overseas distributors, project buyers, and main contractors.
Are you a manufacturer or a trading company?
Vexis Windows & Doors Co., Ltd. is a direct manufacturer with a modern 30,000 m² factory base in Foshan, Guangdong, China. We integrate design, extrusion processing, thermal break assembly, and export sales under one roof.
What is your minimum order quantity (MOQ) and lead time?
We support custom project inquiries. While standard production yields optimal efficiency for full container loads (20GP/40HQ), we also accept small project orders. Our standard production lead time is 15-25 business days following final drawing confirmation.
How do you handle shipping and ocean freight transport protection?
We provide complete container loading (FCL) and LCL crating services. All aluminum sashes and glass units are wrapped in protective film, corner-shielded, and packaged in reinforced wooden crates to ensure zero-damage sea transport to your destination port.
What payment terms do you accept for export orders?
We accept T/T (Telegraphic Transfer) with a 30%-50% deposit upon shop drawing approval and balance prior to shipment loading. Irrevocable L/C at sight is also available for bulk project orders.
Can you manufacture according to local building codes and standards?
Yes. Our engineering team customizes glass thickness (tempered, laminated, hurricane impact), profile thermal breaks, and hardware specifications to meet North American (NFRC/AAMA), European (CE), and Australian (AS2047) standards.
