Insulated systems and enhanced security

Insulated door systems help reduce drafts and heat transfer through the largest openings in your home.
Reinforced frames, layered glass and multipoint locks strengthen the complete entry system.
Custom sizes, finishes, windows and panel patterns create a door that fits the architecture.
Before and After
Compare three design visualizations based on common Ontario door replacement projects. Drag the handle to reveal the upgrade.
These are design visualizations, not photographs of completed customer projects.


Inside the Panel
A garage door is a large moving wall. Steel on both sides protects the panel, while the insulated core helps keep the garage more comfortable through Ontario winters and summer heat.
A continuous insulated core helps slow heat movement through the door.
A solid panel construction helps reduce vibration and everyday door noise.
Steel skins protect both faces of the panel and improve overall rigidity.
Perimeter seals help limit drafts, moisture and winter air infiltration.
Product construction and thermal performance vary by model. Final recommendations are confirmed after measurement and product selection.
The lock, glass, door slab and reinforced frame work together. Explore how each layer strengthens the entrance.
Three-point multipoint lock
Engaging the handle activates locking points at the top, centre and bottom of the door. The load is distributed along the frame instead of depending on one deadbolt.
The animated impact demonstration shows the outer layer cracking while the reinforced assembly remains held together. It is a product visualization, not a claim that glass is indestructible.
Internal steel, an insulated core, weather seals and reinforced lock connections help the entire opening resist movement and reduce drafts.
Security depends on the complete door system, not only the lock.
