How To Caulk Drafty Windows
With winter just effectually the corner, now's the fourth dimension to seal upwardly drafty windows to prevent cold winds from bravado into your dwelling house. Weather condition-tight windows will not but brand your habitation feel more comfy, just also they'll save you money each month by reducing energy consumption, resulting in lower heating bills.
And while there are several ways to seal any drafty windows in your habitation, the best approach requires a two-pronged attack: caulking around the outside of the window and weather stripping the within. Here's a guide on how to nail this process.
The Best Space Heaters
Caulking
Begin by scraping off any old caulk or peeling paint from effectually the exterior perimeter of the window. You could use a regular metallic putty knife to scrape the surface make clean, but a much better option is a 6-in-1 painter'southward tool. This specialty tool has stiff, beveled scraping bract and pointed tip that's neat for raking hardened caulk out of narrow cracks and crevices. And if the beveled terminate becomes wearisome or damaged, you lot can always acuminate it with a demote grinder.
One time you've removed all the old caulk and peeling paint, make clean abroad all dirt and grit using a scrub castor dipped in warm, soapy water. Then, wipe the surface dry with an old towel. Next, utilize a fresh dewdrop of caulk around the outside perimeter of the window, creating a continuous current of air-blocking seal betwixt the window frame and siding, or between the window frame and exterior trim boards. And be certain to utilize an outside-form caulk. I recommend either 100% silicone sealant or a "siliconized" acrylic caulk. Both adhere well and will remain flexible for years. Note, still, that 100% silicone must be cleaned up with mineral spirits; siliconized caulk can be cleaned with water.
Weather Stripping
After caulking effectually the outside of the window, motility inside and use weather condition stripping to seal around the sash. (The sashes are the movable parts of a window that open up and close.) At that place are dozens of unlike styles of weather stripping available for sealing windows, but these are summit 5 types:
Adhesive-backed foam: This is a compression blazon of weather stripping, meaning that when the window closes against it, the cream compresses to seal gaps and block drafts. It features easy skin-and-stick application and cuts with scissors. Just be sure to thoroughly clean the surface area around the inside of the window, as the adhesive won't stick to dusty, dirty surfaces. On double-hung windows, use adhesive-backed foam conditions stripping to the bottom edge of the lower sash, and to the top edge of the upper sash. If you don't want to utilise the weather stripping to the sash, stick it to the sill directly beneath the lower sash, and to the caput jamb above the upper sash. Either style, once the sash is airtight and locked, the foam will seal out drafts. On sliding or casement windows, employ the agglutinative-backed foam to the vertical edge of the sash or vertically along the side jamb.
Tubular rubber-gasket conditions stripping: This is like to adhesive-backed foam, except that it's formed into a hollow rubber tube instead of dumbo foam. When compressed past the sash, the tubular atmospheric condition stripping conforms to the space, effectively sealing out drafts. Some tubular gaskets have peel-and-stick adhesive backing, while others have an fastened metal or forest flange that must be secured with nails or screws. Also look for foam-filled tubular gaskets that take a spongy-cream core, which holds its shape meliorate than the hollow-core gaskets.
Leap Five-Seal: This is a resilient polypropylene plastic or metal strip that comes folded into a V-shape. Information technology's known every bit tension-seal weather stripping because the V-shape springs open up, creating tension between the sash and window frame that blocks the passage of air. Plastic V-seal can exist cutting with pair of scissors, but you'll need aviation snips to cut metal V-seal, which comes in copper, aluminum, bronze, and stainless steel. Also, the plastic type oftentimes has a peel-and-stick backing, while metallic V-seal must be nailed in identify. V-seal can be installed vertically along the sides of double-hung windows, and at the horizontal meeting rail where the 2 sashes see when airtight. On casement or sliding windows, Five-seal is installed along the vertical side jamb where the sash closes.
Felt: Felt is one of the oldest types of weather stripping. It's normally sold in rolls with or without an agglutinative backing and is too available with an attached metal mounting flange. Felt is used as a compression conditions stripping around the inside of double-hung, casement, and sliding windows. Felt is affordable and easy to install, but it doesn't last as long as other types of weather stripping and must be replaced every four to six years.
Window insulation kits: These kits block cold air by sealing the entire window backside a big canvas of shrink-wrap plastic. The plastic adheres to the interior window casing with double-sided tape; y'all and then use a blow dryer to seal it in place. Window insulation kits are very effective at sealing out drafts, but keep in listen that you won't be able to open up the window until adjacent spring, when yous peel off the plastic wrap.
Hither's i final tip for sealing drafty double-hung windows. Most of them take a single sash lock installed at the horizontal meeting rails where the upper and lower sash meet. To ensure that the two sashes fit tightly together, add a second sash lock: Unscrew the existing sash lock and reinstall it about 1-third of the way in from the side jamb. For case, if the window is 24 inches wide, move the sash lock from the middle of the sash to about 8 inches from the cease. Side by side, purchase a second sash lock and install it 8 inches in from the reverse side jamb. Now, when you engage both locks, the sashes volition fit together tightly.
