Outward Opening Aluminum Casement Window Reliable EPDM Sealing For Villa Exterior Wall Installation

Product Description

We are a professional manufacturer of aluminum outward opening windows, the space-saving casement solution that opens fully outward without occupying any interior space. Featuring 6060-T6 thermal break profiles, multi-chamber construction and multi-point locking hardware with four-bar friction hinges, our outward windows provide maximum ventilation, excellent sealing and reliable security. Available in side-hung and top-hung opening styles, fully customizable in size, color and glazing. NFRC certified, OEM/ODM supported. Contact us for a quotation, or send your drawings for a custom quote.

Key Features

1. Maximum Ventilation — the sash opens fully outward, bringing fresh air into the room while occupying no interior space.

2. Space-Saving Design — the window swings outward, keeping curtains, blinds and floor space completely free.

3. Reliable Outward Hardware — four-bar friction hinges hold the sash firmly at any open position; an optional restrictor limits the opening angle for safety.

4. Multi-Point Locking Security — locking points around the sash perimeter resist prying, with optional safety locks.

5. Thermal Break Energy Efficiency — PA66GF25 thermal break strips and multi-chamber profiles achieve a U-Factor as low as 1.0 W/(m²·K).

6. Excellent Sealing — multi-seal EPDM gaskets deliver Class 8 air permeability and Class 6 water tightness.

7. Weather Resistance — press-sealed gaskets with a proper drainage system keep out wind and rain.

8. Full Customization — size, color, glazing and hardware fully customizable; OEM/ODM supported.

Specifications

Materials & Finish

• Aluminum profiles: 6063-T5 aluminum alloy — high tensile strength, corrosion resistant, long service life
• Surface finishes: anodizing (AA15–AA25), powder coating (≥ 60μm), PVDF coating, wood/stone grain transfer — strong adhesion, weather and UV resistant
• Thermal break strips: PA66GF25 nylon (14.8–34.8mm) — high strength, stable insulation performance
• Gaskets: EPDM composite gaskets, -40°C to 120°C, aging resistant
• Hardware: four-bar friction hinges, multi-point locking espagnolette, zinc alloy handles, optional restrictor and safety chain
• Glass: automotive-grade float glass; tempered, laminated, Low-E, argon-filled IGUs optional
• Processing: CNC cutting (±0.5mm accuracy), corner crimping with adhesive, complete assembly and opening/closing test of every window

Assembly & Installation

Installation steps:

• Measure the opening — verify actual opening dimensions, level and plumb
• Install the frame — fix with expansion bolts / connectors; adjust level and plumb to within 2mm
• Hang the sash — install the sash on the four-bar friction hinges and adjust for smooth outward opening and tight closure
• Waterproofing — fill gaps between frame and wall with foam, apply weather-resistant sealant with a drainage slope; ensure drainage holes are unobstructed
• Final adjustment — check opening angle, restrictor and locking points, remove protective film and clean

FAQ

Q1: Can an outward opening window be used on high floors?

A: Outward opening windows are best suited to low and mid-rise buildings. For upper floors, a restrictor or safety chain can limit the opening angle, or tilt & turn windows are recommended.

Q2: What is the difference between outward and inward opening windows?

A: Outward windows open away from the room, saving interior space and allowing full opening for ventilation; inward windows open into the room, making cleaning easier from inside.

Q3: How is the window cleaned?

A: Outward windows are cleaned mainly from outside. For high-rise buildings, we recommend inward opening or tilt & turn windows instead.

Q4: What is the minimum order quantity (MOQ)?

A: custom MOQ depends on configuration — confirm with our sales team.

Q5: What is the production lead time?

A: Around 15–25 days for standard windows and 25–35 days for custom orders; partial shipments can be arranged for large orders.

Q6: What is the maximum opening sash size?

A: Outward opening sashes are generally produced up to about 1200mm wide × 1800mm high, subject to hinge load capacity and wind load calculation.

Q7: Do you support OEM/ODM?

A: Yes. We offer private label, logo printing, custom packaging, and new product development from customer drawings.

Q8: What is the warranty? How is after-sales handled?

A: 3 years on profile structure and 5 years on hardware. Report issues with photos and we will provide a solution within 48 hours.

Q9: What glazing options are available?

A: Double glazing, triple glazing, Low-E, laminated, tempered, frosted and built-in blinds. We can recommend the right configuration for your local climate.

Q10: How do you guarantee quality?

A: We use qualified suppliers for profiles, glass and hardware, run QC throughout production, and inspect every window before shipment with a certificate of conformity. Test reports are available.

Q11: Can I get a sample?

A: Yes. Samples / sample windows are available free or at cost (freight paid by customer); the sample fee is deductible from the first order.
