Glass & Security
Fibreglass slab + Cardinal IG insert
Fibreglass doors have the best thermal performance of any entry-door slab we install — the composite skin doesn't conduct cold the way steel does and doesn't move with moisture the way wood does. That makes the glass insert the single thermal compromise on the door, which is exactly why we don't compromise on it.
Trust Build's standard fibreglass-door spec is a triple-pane Cardinal IG insert with Low-E 272 and argon fill, tempered safety glass per code, and a laminated inner pane on any insert larger than the standard 8x36 lite. The result is a door that achieves U-values in the 0.18-0.22 range — among the best in the residential entry-door category.
Triple pane + Low-E 272 + argon
Standard insert package — matches the thermal performance of the fibreglass slab itself.
Tempered + laminated
Code-compliant safety glass with laminated forced-entry resistance on any larger insert.
Decorative leaded or etched
Available with full triple-pane Cardinal IG underneath — no thermal penalty for choosing decorative.
Impact-resistant assembly
For coastal or rural Ontario properties where storm debris is a real consideration.
Security Window Film: Fibreglass-door glass inserts are excellent candidates for Security Window Film retrofits — the slab is already secure; film matches the glass to it. Learn more about Security Film →
