Window System

Natural Wood Interior Finish

Interior wood cladding brings warmth, texture and a furniture-quality appearance to the room, with multiple wood species, stains and coating colours available.

‍

Durable Aluminum Exterior

The thermally broken aluminum structure protects the exterior from changing weather conditions while reducing the maintenance associated with exposed exterior wood.

‍

Flexible Tilt-and-Turn Ventilation

The operable sash can open fully inward for maximum airflow and cleaning access, or tilt inward for secure and controlled everyday ventilation.

‍

High-Performance Thermal Construction

A 75 mm frame, wide insulating thermal break and insulated glazing options support energy efficiency, indoor comfort and performance across a range of climate conditions.

‍

Certified Air, Water and Structural Performance

Selected fixed and operable EX88S configurations achieve CW-PG80 ratings, with tested resistance to high design pressures and water penetration.

‍

The Elite Series brochure describes EX88S as thermally broken aluminum with interior wood cladding. It lists a 75 mm frame in the EX88S detail drawing, CW-PG80 ratings for fixed and operable units, and NFRC-certified U-factor configurations from 0.20 to 0.33.

‍

Comfort
Insulated glazing, thermal separation and natural interior wood finishes create a warmer and more refined indoor environment.
Ventilation
Tilt-and-turn operation supports both secure background ventilation and full inward opening for maximum airflow and cleaning access.
Integration
Natural wood interiors and durable aluminum exteriors allow the system to coordinate with both interior millwork and exterior architecture.
