Glass & Security
The biggest piece of glass on your home
A sliding patio door is the largest single glass opening in a typical Ontario house — and it's at grade, hidden from the street, often shielded by a deck or fence. From a security and energy perspective it deserves more attention than almost any other opening on the home. Trust Build spec's patio doors with that in mind.
Our standard patio-door glass is a triple-pane Cardinal IG package with Low-E 272 and argon, tempered safety glass (code-required), and a laminated inner pane on the operating panel for forced-entry resistance. The fixed panel gets the same package for visual continuity. The result is a patio door that's both noticeably warmer in winter and one of the hardest residential glass openings to defeat from the yard side.
Triple pane + Low-E 272 + tempered
Standard patio-door spec. Energy Star certified. Tempered glass is code-required on patio openings.
Laminated operating panel
Strongly recommended — defeats break-and-reach attacks on the patio door latch, which is the most common patio-door entry method.
Triple pane + Low-E 366
For south-facing patio doors that overheat the adjacent room in summer.
Impact-resistant laminated assembly
Highest security tier — common on rural properties and ground-floor patio doors on secondary suites.
Security Window Film: If your patio door isn't being replaced this season, Security Window Film on the existing glass is the single highest-impact security upgrade you can make to your home — patio glass is the most common ground-floor forced-entry point. Learn more about Security Film →
