Glass & Security
Sliding sashes, smarter glass choices
Slider windows ventilate by sliding one sash horizontally past the other. Because the sashes overlap rather than compressing against the frame, the glass package has to compensate for a slightly looser air seal — which is why we always recommend triple-pane Cardinal IG with a Low-E coating on our sliders, not double-pane.
For ground-floor sliders, especially those that face a side yard or a quiet back street, we strongly suggest a laminated inner pane. The horizontal lock on a slider is solid, but laminated glass closes the second-most-common forced-entry path — breaking the glass to reach the latch.
Triple pane + Low-E 272 + argon
Trust Build's slider standard. Compensates for the looser slide-against seal and meets Energy Star in every Canadian zone.
Laminated inner pane
Strongly recommended on ground-floor sliders — defeats break-and-reach forced entry without changing the look.
Tempered glass
Required by code on any slider within 18" of a finished floor or adjacent to a patio door.
Acoustic laminated
For sliders on bedroom walls facing busy streets — adds 6-8 STC of noise reduction.
Security Window Film: Security Window Film is one of the most cost-effective upgrades for existing slider windows where replacing the glass isn't in the budget yet. Learn more about Security Film →
