Aluminum Casement Wi | Aluminum Window China

Product Overview

JuSen Doors' thermal insulation aluminum casement windows utilize 6063-T5 aluminum alloy frames with polyamide thermal break strips to reduce heat transfer. Multi-chamber profiles accommodate double or triple glazing for enhanced energy efficiency, with EPDM weatherstripping ensuring airtight sealing. These windows comply with EN 14351-1 for thermal performance and air permeability.

Frequently Asked Questions

What is the U-value of the thermal insulation aluminum casement window?

With double glazing (5+12A+5 mm, Low-E coating), the U-value is approximately 1.6 W/m²K. Triple glazing reduces this to 1.2 W/m²K, meeting passive house standards.

Can I customize the thermal break width for extreme climates?

Yes, we offer thermal break strips from 24 mm to 34 mm width. Wider breaks improve insulation for sub-zero conditions, but frame depth may increase to 70 mm.

Are these windows suitable for coastal environments with salt spray?

Absolutely. We recommend anodized finish (AA15 grade) for corrosion resistance against salt air. Powder coating with marine-grade polyester is also available.

What hardware locking options are available for security?

Standard multi-point locking systems include a central lock with shoot bolts on the hinge side. Upgraded options feature anti-pick cylinders and security bolts tested to DIN 18251 class 3.

What is the lead time for a custom order of 200 units?

Lead time is 25-35 working days after design approval and deposit. Express production (18-22 days) is available for an additional 10% surcharge.
