Overview
Rigid exterior insulation installed under new siding to cut thermal bridging, lower heating bills and keep Southern Ontario winters outside where they belong. Installed with proper air sealing and moisture detailing.
- Rigid foam and insulated siding systems
- Air sealing and vapour detailing
- Noticeably lower winter heating costs
- Installed with your siding as one job
Material advantages: vinyl vs. aluminum
Both hold up in Southern Ontario — the right choice depends on the home, the detailing and the budget.
Durability
- Vinyl
- Impact-resistant and won't dent; premium panels handle wind uplift and freeze-thaw without cracking.
- Aluminum
- Rigid and fire-resistant, holds a crisp bent profile for decades, but can dent on hard impact.
Energy Efficiency
- Vinyl
- Insulated panel options add continuous R-value and cut thermal bridging across studs.
- Aluminum
- Minimal R-value on its own; best paired with rigid exterior insulation underneath.
Maintenance
- Vinyl
- Colour runs through the panel — an annual rinse is usually all it needs.
- Aluminum
- Baked enamel finish never needs painting; scratches can be touched up or re-capped.
Cost
- Vinyl
- Lower installed cost per square foot with the widest colour and profile selection.
- Aluminum
- Higher material and labour cost, justified where custom bends, capping or heritage profiles are required.
