To weather strip an old window, you will typically use a combination of materials like foam strips and V-channel weatherstripping, applying them to both the window sash and the jamb to seal gaps and prevent drafts. The process involves cleaning the surfaces, cutting the weatherstripping to size, and carefully applying or inserting it into the appropriate areas.
Weatherstripping old windows is a cost-effective way to improve energy efficiency and comfort in your home by reducing air leaks. Here's a breakdown of the steps, drawing from common practices and the provided reference:
Proper weatherstripping helps seal gaps around movable window sashes, keeping warm air in during winter and cool air in during summer. This process often involves applying different types of seals to the window frame (jamb) and the window itself (sash).
Preparing the Window
Before applying any weatherstripping, it's crucial to prepare the surfaces.
- Clean the Sash: Begin by thoroughly cleaning the surfaces of the window sash where weatherstripping will be applied. Remove any dirt, debris, or old weatherstripping residue. A clean surface ensures the adhesive (if applicable) sticks properly. (Reference Step 1 & 8)
Applying Foam Weatherstripping
Foam weatherstripping is often self-adhesive and easy to install, commonly used on meeting rails or bottom sashes.
- Cut the Weatherstripping Material: Measure the length of the sash or jamb section you plan to cover and cut the foam weatherstripping to the appropriate size using scissors or a utility knife. (Reference Step 2)
- Insert the Foam Weatherstripping: Carefully peel the backing off the adhesive side of the foam strip and press it firmly into place on the designated area of the sash or jamb. Ensure it creates a good seal when the window is closed. (Reference Step 3)
Applying V-Channel Weatherstripping
V-channel weatherstripping (also known as tension seal or spring metal) is often used on the sides of the window jamb or meeting rails to create a spring-like seal against the sash.
- Clean the Jamb: Just like the sash, clean the window jamb surfaces where the V-channel weatherstripping will be inserted or applied. Remove any dirt or debris. (Reference Step 4)
- Cut V-Channels: Measure the length of the jamb sections where the V-channel will be installed and cut the V-channel material to size. (Reference Step 5)
- Insert V-Channel Into Jamb: Carefully insert the V-channel weatherstripping into the gap along the side of the window jamb. The "V" shape should face outwards towards the sash. (Reference Step 6)
- Drive Finish Nails Into Weatherstripping: Secure the V-channel weatherstripping in place by carefully driving small finish nails through it and into the window jamb. Space the nails evenly to keep the strip flat and secure. (Reference Step 7)
By combining different types of weatherstripping and carefully following these steps, you can significantly reduce drafts and improve the efficiency of your old windows.
