Practical Building Envelope Upgrades for Existing Homes

Most Canadian homes lose heat through drafts, poor insulation, and aging windows. The good news? You don’t need a full renovation to make a big difference. A few targeted upgrades can dramatically improve comfort, reduce monthly energy bills, and protect your home from moisture damage.

Top 5 High-Impact Upgrades

1. Air Sealing (Best ROI)

Fixing drafts around windows, doors, attics, and basements stops warm air from escaping and keeps your home consistently comfortable.

2. Attic Insulation

Upgrading to R-50–R-60 greatly reduces heat loss and prevents ice dams in winter.

3. Basement/Rim Joist Insulation

Sealing and insulating the basement makes floors warmer, reduces humidity, and stops cold drafts.

4. High-Performance Windows

Triple glazing and low-e coatings improve comfort, reduce condensation, and cut energy loss.

5. Ventilation (HRV/ERV)

A tighter home needs controlled fresh air. Modern ventilation systems improve indoor air quality while saving energy.
