Advanced Features of Our Casement Windows

Our casement windows combine energy-efficient glazing, airtight frames, and secure hardware, engineered to perform in the Canadian climate.

Crank-Operated Smooth Opening

Our windows use durable crank-operated mechanisms for smooth sash movement and precise ventilation. Designed for reliability, the hardware allows easy operation even in hard-to-reach areas and maintains consistent performance through years of daily use.

Multi-Point Locking Systems

We install multi-point locking hardware that secures the sash tightly against the frame, reducing air leakage and improving security. This system distributes pressure evenly, preventing warping and keeping your home safe while maximizing energy efficiency.

Low-E & Argon Gas Insulated Glass Units

Our casement windows feature Low-E coated glass with argon gas-filled double or triple panes. These insulated glass units minimize heat loss, block UV rays, and maintain indoor comfort. Each unit meets ENERGY STAR® and CSA performance standards.

Fusion-Welded Vinyl or Fibreglass Frames

We use fusion-welded multi-chamber vinyl and durable fibreglass frames for maximum strength and insulation. These materials resist warping, condensation, and moisture damage, ensuring long service life with minimal maintenance in GTA conditions.

Airtight Weather Seals

Our casement windows close tightly with compression weather seals that eliminate drafts and water infiltration. This technology ensures consistent thermal performance, keeping homes warmer in winter, cooler in summer, and reducing energy costs year-round.

Custom Colours, Sizes & Hardware

We offer complete customization with made-to-measure sizing, grille patterns, frame colours, and hardware finishes. Every casement window is designed to fit your home’s architecture, delivering both functional performance and visual appeal.

CSA-Tested Durability for Canadian Climate

All our casement windows are CSA-tested for structural integrity, thermal efficiency, and water resistance. Built to perform in Ontario’s extreme weather, they withstand high winds, heavy rains, and sub-zero temperatures without compromising function.

Benefits of Casement Windows for GTA Homeowners

Our casement windows improve efficiency, comfort, and home value in the GTA with advanced glazing, airtight seals, and CSA-certified frames. All the benefits of our casement windows are:

Casement windows form a tight sash-to-frame seal that minimizes air leakage. Combined with Low-E coatings and argon gas-filled insulated glass units, they cut heating and cooling costs for GTA homeowners while maintaining indoor comfort year-round.

The 90° outward-opening design works like a funnel, directing fresh air indoors for stronger ventilation. This improves indoor air quality and allows natural cross-breezes, making casement windows ideal for living rooms, kitchens, and upper floors.

Casement windows feature slim fusion-welded frames with large glass surfaces and no meeting rail in the center. This design maximizes visible light and provides wide, unobstructed views, perfect for modern GTA homes or properties with scenic surroundings.

Our casement windows use multi-point locking systems and reinforced frames to resist forced entry. With the sash pressing tightly into the frame, they offer stronger protection compared to sliding or single-hung windows, increasing home security.

Double or triple-pane insulated glass units reduce outside noise from traffic, transit, or busy streets. Combined with compression seals, these casement windows create a quieter indoor environment, ideal for homes across the GTA.

CSA-tested casement windows are built for Canadian weather, resisting warping, condensation, and water infiltration. Their airtight seals and strong frames perform reliably against heavy snow, wind, and temperature swings common in the GTA.

Upgrading to casement windows improves thermal comfort, reduces drafts, and enhances curb appeal. With custom colours, grille patterns, and ENERGY STAR® certified performance, they add long-term value to GTA homes and boost resale potential.
