1.8mm Stainless Steel Double Glazed Casement Window –

Product Overview

Constructed from 1.8mm wall thickness 6063-T5 aluminum alloy combined with double-glazed tempered glass panels, these swing casement windows deliver sound transmission class (STC) ratings suitable for basement environments. Each unit integrates stainless steel hinges and multi-point locking hardware to meet industrial-grade acoustic isolation requirements.

Frequently Asked Questions

What is the actual sound reduction performance for the double glazing?

The standard 5mm+12Ar+5mm configuration achieves STC 35-38. Upgrading to 6mm laminated glass on one pane with a 16mm air gap increases the rating to STC 42. All values are verified per ASTM E413 classification.

Can the stained finish be matched to existing wood window frames?

Yes, we offer custom color matching by sending a physical wood sample or RAL code. The staining process uses UV-resistant polyurethane topcoats applied in three layers to achieve consistent color depth and gloss level.

Is this window suitable for egress requirements in a basement bedroom?

When ordered with the outward-swing configuration and a minimum clear opening of 0.33m² (per IRC 2021), these windows meet egress standards. A restrictor stay can be added to limit swing angle for safety while maintaining the required clear opening.

What hardware options are available for commercial or industrial projects?

We supply multi-point locking systems with hardened steel shoot bolts and keyed cam handles. For high-traffic areas, we recommend the optional push-button handle with a 10,000-cycle lifespan tested per EN 13126.

What is the typical lead time for custom-sized windows?

Standard sizes ship within 15 working days from order confirmation. Custom sizes require 20-25 working days due to extrusion and fabrication. Sample units for approval can be produced in 10 working days.
