Q: What is weather-stripping, and should I apply it to my windows and doors to prepare for winter?
A: Weather-stripping is a strip of material used to seal the joint between a window or door and its surrounding frame—like the sill, casing, or threshold. It helps block drafts, rain, snow, and cold air from entering your home.
Why Use Weather-Stripping?
If you’re looking for a temporary and affordable solution to stop drafts, reduce energy waste, and lower your heating bills, weather-stripping is a great option.
💡 Did you know? Drafty windows and doors can account for up to 40% of your heating and cooling costs!
That said, weather-stripping isn’t meant to be a long-term fix. Over time, the materials degrade, lose their seal, and require replacement.
4 Types of Weather-Stripping (Pros, Cons & Installation Tips)
1. Self-Adhesive Foam
Made from open- or closed-cell foam, this option is sold in various widths and thicknesses.
✅ Pros:
Ideal for irregular-sized gaps
Closed-cell foam seals well and scores high in wind tests
❌ Cons:
Tends to peel off over time
Visually unappealing and not eco-friendly
Frequent replacement needed
🔧 Install: Cut to length, peel, and press into place.
2. Tubular Rubber or Vinyl Gasket
These gaskets come mounted on strips and are typically used for doors.
✅ Pros:
Forms a strong air seal
Can be stapled securely in place
❌ Cons:
Bulky and visible
Prone to cracking and drying out
🔧 Install: Peel and stick, or staple to door frame.
3. Spring V-Shaped (Tension Seal)
A durable spring strip that bridges gaps with a tight seal.
✅ Pros:
Highly effective and discreet
Long-lasting when properly installed
❌ Cons:
Can bend or misalign
Installation requires precision
🔧 Install: Peel and stick or use finishing nails.
4. Nail-In Copper Weather-Stripping
This sturdy option includes pre-punched holes for nails.
✅ Pros:
Offers one of the most secure, long-lasting seals
❌ Cons:
Installation is tricky and often requires a professional
🔧 Install: Fit interlocking pieces around the door or window perimeter and notch them using a router.
Weather-Stripping Application Tips
Apply to a clean, dry surface when temperatures are above 20°F
Press snugly between both surfaces; ensure tight corners and full contact
For doors, apply a continuous strip along the entire jamb
For windows, be sure the strip doesn’t block proper function
How to Check for Drafts
Here are two simple methods:
Flame Test: Hold a lighter near your window or door frame. If the flame flickers, air is coming through.
Thermal Gun: Use a temp gun (or borrow ours!) to detect cold spots and thermal leaks.
These tools help you pinpoint air loss and determine whether your windows and doors are properly sealed.
