Caulk
Caulking is a simple yet effective way to seal gaps around your windows, preventing drafts and improving insulation. Proper caulking can significantly reduce energy costs and enhance the comfort of your home.
How to Caulk Around a Window
- Clean the Window: Before you start, make sure the window area is clean. Use a microfiber cloth and some mild soap or rubbing alcohol to remove any dirt or debris.
- Cut the Caulk Tube: Use a sharp utility knife to cut the tip of the caulk tube. A straight, clean cut will help you achieve a smooth caulk line. Some people prefer a steep angle, while others go for a nearly straight cut. Cut near the tip for a small bead of caulk.
- Apply the Caulk: Using a caulking gun, apply the caulk to the window. Start in an inconspicuous area to get the hang of it. Rest the tip against the joint, squeeze the trigger, and move the tip along the joint as the caulk emerges.
- Smooth the Caulk: If the bead looks good, leave it alone. If not, use your finger to smooth it out. This ensures the caulk adheres well to both sides of the joint.
Caulking is a cost-effective way to improve your home's insulation. It helps seal gaps that let in cold air during winter and hot air during summer, making your home more energy-efficient.
For an added measure of weather-stripping during cold months, you can also use rope caulk. This helps seal various window materials but needs to be removed in the spring.
Glazing Putty
Glazing putty is essential for sealing windows and improving insulation. If you notice that the glazing putty on your window is cracked, missing, or curling from the glass, it's time to repair it. Here's a simple guide to help you through the process:
- Remove Old Putty: Use a putty knife or chisel to scrape away loose or damaged putty.
- Clean the Area: Ensure the surface is clean and free of debris. Applying a little linseed oil can help the new putty adhere better.
- Apply New Putty: Roll a small amount of glazing putty into a thin rope and press it into the window frame. Smooth it out with a putty knife for a clean finish.
Properly applied glazing putty can significantly improve your window's insulation, reducing drafts and energy costs.
For those using pgt window parts, make sure to choose the right type of putty for your specific window model. Products like the wrs .187" x .170" glazing wedge weather stripping and the wrs weather stripping glazing channel are excellent choices for enhancing weatherability and chemical resistance in aluminum or vinyl windows.
Self-Stick Foam Weatherstripping
Self-stick foam weatherstripping is a simple and cost-effective way to seal windows. It's easy to apply and works well for casement and sliding windows. The foam comes in various thicknesses, so make sure to test if the window will close after application.
What You'll Need
- Tape measure
- Scissors or tin snips
- Clean rags
- Dish detergent
Steps to Install
- Clean the surface where the foam will be applied using dish detergent and water. Ensure it's dry and free of dirt or grease.
- Measure the length needed and cut the foam strip to size with scissors or tin snips.
- Peel off the backing at one end and press the strip in place, peeling and pressing as you work toward the other end.
- If the backing is stubborn, stretch the foam until the seal between the backing and foam breaks.
- Attach the strips on the hinge side to the doorjamb.
Self-stick foam weatherstripping is a quick fix but usually doesn't last long. It can last from one to three years, providing a temporary but effective seal against drafts.
Spring Bronze Weatherstripping
Spring bronze weatherstripping is a durable and long-lasting solution for sealing windows.

- Attach with Nails: Use small nails to secure the strips in place. Start by driving a nail at the top and bottom of each strip, then add more nails along the length of the strip. Be careful not to drive the nails all the way in; leave them slightly raised to avoid damaging the bronze.
- Test and Adjust: Close the window to check the fit. If there are any gaps, use a putty knife to gently bend the bronze and close the gaps.
Spring bronze weatherstripping is a great choice for those looking for a long-term solution to improve their home's insulation. While it requires a bit more effort to install compared to other types of weatherstripping, the results are well worth it.
This type of weatherstripping is available in rolls and can be used for both windows and doors. It's a versatile option that can help you save on energy costs by keeping your home better insulated. Whether you're working on biltbest window parts, andersen window parts, or any other parts of a window, spring bronze weatherstripping is a reliable choice.
Tubular Vinyl
Tubular vinyl is a cost-effective solution for sealing large gaps around windows. This type of weather stripping is made from highly flexible vinyl, which allows it to conform to uneven surfaces easily. However, it is usually applied on the exterior of windows because it can be visually unappealing.
To install tubular vinyl weather stripping, follow these steps:
- Measure the length of the gaps you need to seal.
- Cut the vinyl strips to the required size using scissors.
- Close the window and press the vinyl strip firmly into place.
- Secure the vinyl with small nails or staples.
Tubular vinyl is available in white and gray, but it should not be painted as paint can cause the material to stiffen and lose its flexibility.
For added insulation, consider using foam-filled tubular vinyl. This type includes a foam core that provides extra strength and helps the vinyl maintain its shape better than hollow-tube versions. Remember, the foam-filled option also should not be painted.
Rope Caulk
Rope caulk is a versatile and easy-to-use material for sealing windows. It's perfect for temporary insulation during the colder months. This type of caulk is pliable and can be pressed into gaps around windows to block drafts effectively.
How to Apply Rope Caulk
- Clean the Area: Before applying rope caulk, make sure the window area is clean and free of debris. Use a microfiber cloth and mild soap or rubbing alcohol to clean the surface.
- Unroll and Press: Unroll the rope caulk and press it into the gaps where the sash meets the stops, between the top of the lower sash and the bottom of the upper sash, and in the pulley. This will help seal various window materials.
- Temporary Solution: Keep in mind that the window can't be opened while the rope caulk is in place. Remove it in the spring when the weather gets warmer.
For a quick but temporary window weather seal, use rope caulk or a shrink-wrap plastic window kit, which can be removed when the weather gets warm.
Plastic Shrink Wrap
Plastic shrink wrap is a great way to insulate your windows during the cold months. This method is both affordable and effective in blocking drafts and keeping your home warm.
To get started, you'll need a shrink-wrap window cover kit. These kits usually come with plastic film and double-sided tape. Here's a simple step-by-step guide:
