Aluminum Casement Windows: 2026 The Complete Guide to EAFA's Outward-Opening Range

EAFA's outward-opening aluminum casement windows combine engineering precision, structural integrity, and refined aesthetics — if you're comparing casement windows for your next project, this is your starting point. Five distinct models span everything from hurricane-grade toughness to ultra-slim sightlines and triple-glazed serenity. Here's the full lineup at a glance.

• 1.8 mm wall + 4 chambers: Double injection-molded corners eliminate leaks; reinforcing ribs spread load evenly across the frame.
• 55 mm sash depth (22% wider than industry 45 mm) with a closed-edge bead (the trim that holds the glass has no visible seams) for clean, uninterrupted sightlines.
• Vertical isotherm design (keeps the thermal break and gasket on the same line to block heat transfer) with triple EPDM foam seals (durable rubber-like gaskets that stay flexible for years) — thermal break, equal-pressure gasket, and insulation strip aligned to cut heat transfer.

• Glazing: Standard 5+20A+5, optional 15+18A+15 (48 mm total) for maximum span — rated to 12 m².
• Acoustic performance: Rw ≥ 35 dB. Frame: 110 mm × 1.8 mm, meets GB/T 8478-2020 top wind-resistance grade.

• 2.0 mm wall + 7-chamber profile: Quad-direction bracing bars turn the frame into a rigid cage; sash edges thickened to 2.3 mm.
• 24 mm deep glazing channel (vs. typical 15 mm) securely embeds thick glass; closed-angle bead forms a "golden triangle" stress path that converts wind pressure into frame-level internal force.

• 80 kg hardware rating: 15-inch 304 stainless steel hinges, 3 mm thick, single-sash load-tested to 80 kg.
• Ultra-clear tempered glass standard — self-explosion rate ≤ 0.01% vs. industry 0.3%.
• Colors: Silver grey, starry grey, palace white, metallic coffee, anthracite zinc grey, champagne gold.

• 1.8 mm wall: 35.3 mm extra-wide thermal break + insulating wool fill for thermal performance.
• 8-seal system: Main gasket fully welded around the frame — no joins, no leaks. Expanded injection corner keys and pressure-bead tech reinforce large-glass frame integrity.

• Full safety suite: R-rounded corners on all four frame angles eliminate sharp indoor edges; anti-drop safety chain + ultra-white diamond mesh + slim guardrail.
• German Weihagen dual-height base-less handle matches frame color for a flush, ergonomic look.
• Standard colors plus 20 Morandi hues — cocoa-egg-milk, muted blues, and more — for true architectural customization.

• 2.0 mm wall + 5 chambers: Triple-seal design for airtight, watertight performance; vertical isotherm alignment reduces indoor energy loss.
• Patented stepped floor drainage + patented anti-backflow seal — water drains fast, never reverses, even under driving rain.

• Dual-angle child safety: R6 metal arc corner guard on the sash + PET anti-collision corner pad.
• 30 mm multi-cavity thermal break (multiple insulating chambers inside the frame that stop heat from traveling through the metal) cuts indoor-outdoor heat convection.
• Colors: Silver grey, starry grey, palace white, metallic coffee, Thai teak, Burmese rosewood.

• Triple glazing: 5+12A+5+12A+5 — 25–33% more noise reduction vs. standard double glazing.

• 2.0 mm wall + 5 chambers: Multi-cavity thermal break and dense frame structure for low-carbon efficiency.
• Same waterproof backbone as E9: Patented stepped floor drainage + anti-backflow seal — proven in heavy rain.
• Colors: Silver grey, starry grey, palace white, metallic coffee, Thai teak, Burmese rosewood.

Built on low-maintenance aluminum frames that never need painting or sealing, the range shares a common engineering backbone.

• Global hardware supply chain: Profiles by Xinhe Aluminum; hardware from Roto, GU, Siegenia, Hoppe, Weihagen.
• GB/T 8478-2020 compliance: Wind-resistance tested to the highest grade across all models.
• Injection-molded corner assembly: Double bracket + expansion key for leak-proof, high-rigidity joints.
• Deep glazing channels & closed-edge beads: Industry-leading glass embedment and clean aesthetics shared across V8, D17, and 90S.

• Coastal typhoon zone → D17
• Street-facing noise → S9
• Villa oversized glazing → V8
• Architectural color customization → 90S
• All-round balance with imported hardware → E9
