Product Overview

High-performance inward-opening windows are engineered architectural systems designed to tilt inward for secure, top-ventilation or swing fully open for maximum airflow and easy cleaning. Engineered with advanced thermal breaks and multi-point locking mechanisms, these windows deliver acoustic insulation, and structural integrity for modern commercial and residential projects.

Product Features

Multi-Layer Sealing: Three-tier EPDM (Ethylene Propylene Diene Monomer) synthetic rubber gaskets eliminate air infiltration and water draft.

Concealed Drainage System: Engineered internal weep holes and pressure-equalized channels ensure efficient water evacuation without visible exterior caps.

High Wind-Load Resistance: Engineered to withstand structural wind pressures up to Class 5 (ASTM E330), making them highly suitable for high-rise coastal developments.

Superior Water Tightness: Prevents water penetration under driving rain up to 700 Pa pressure, protecting interior building envelopes from moisture and mold.

Certified Quality Assurance

North American Standards: Fully tested and certified in compliance with NAFS (North American Fenestration Standard), AAMA/WDMA/CSA 101/I.S.2/A440.
European Standards: CE Certified according to EN 14351-1, ensuring conformity with all European health, safety, and environmental protection legislation.
Impact Rating: Available with NFRC certification for thermal performance and structural impact ratings for hurricane-prone zones.

OEM & ODM Customization

Custom Profiles & Sizing: Tailored frame depths (60mm, 70mm, 80mm) and bespoke sizing up to structural limits.
Color Matching: Full RAL color chart with dual-color options (different interior and exterior finishes).
Private Labeling: Custom branding on protective films, hardware engraving, and packaging documentation.

Packaging & Logistics

Export Packaging: PE surface film, shock-absorbing foam corner guards, and reinforced, ISPM-15 compliant wooden crates secured with heavy-duty tension strapping.
Lead Times: 25–30 business days for standard projects; 40–50 business days for bespoke or high-volume commercial orders (from technical sign-off).
Logistics & Terms: Full compatibility with FOB, CIF, DDU, and DDP terms via ocean freight (FCL/LCL), intermodal rail, and expedited air transport.

FAQ

Q1: How do inward-opening windows handle heavy rainfall without leaking?
A: Our systems utilize a multi-chamber barrier design and high-flexibility EPDM gaskets. Rainwater entering the outer track is immediately directed away through internal, pressure-equalized drainage slots, preventing any back-flow into the building interior.
Q2: Can these windows accommodate specific North American building code requirements?
A: Yes. We manufacture profiles according to specific structural wall thicknesses and glass requirements necessary to pass local AAMA and NAFS testing, ensuring seamless building inspections.
Q3: What is the minimum order quantity for custom OEM color options?
A: For non-standard RAL colors or dual-color extrusions, our minimum order quantity typically starts at 100 square meters of window area, which satisfies standard commercial prototyping or custom residential batches.
