What's the best weatherstripping for an entry door in Ottawa?

EPDM rubber weatherstripping is the best choice for Ottawa entry doors, offering superior durability against our harsh freeze-thaw cycles and temperature extremes from -30°C to +35°C.

For Ottawa's climate, you want weatherstripping that maintains flexibility in extreme cold while resisting UV damage during hot summers. EPDM rubber weatherstripping excels in both conditions and typically lasts 10-15 years with proper installation. It creates an excellent seal against air infiltration, which is crucial for energy efficiency during our long heating season.

Door sweep weatherstripping should be adjustable aluminum with a rubber or vinyl insert that can handle snow buildup and ice formation. The sweep needs to seal tightly against your threshold while allowing the door to open freely even when ice accumulates. Avoid basic foam strips or cheap vinyl options - they'll crack and fail within 1-2 Ottawa winters.

For door jamb weatherstripping, look for compression-style EPDM that's specifically rated for exterior use. The weatherstripping should compress about 25% when the door closes to create a proper seal without making the door difficult to operate. Quality weatherstripping will have a durometer rating between 50-70 Shore A for the right balance of flexibility and durability.

Installation timing matters in Ottawa - avoid installing weatherstripping during extreme cold (below -10°C) as the adhesive won't cure properly and rubber materials become brittle. Spring and fall are ideal installation seasons.
