Next, apply a fresh bed of caulk around the outside perimeter of the window, creating a continuous airtight seal between the window frame and siding or trim boards. And be sure to use an outside-grade caulk, such as 100-percent silicone sealant, or "siliconized" acrylic caulk. Both types adhere well and will remain flexible for years.
windows with high-quality sealant.
After caulking the outside of the window, motility inside and utilize weather condition-stripping to seal around the sash, which are the moveable parts of the window that open and close. There are many different kinds of atmospheric condition-stripping available; here's a detailed look at the elevation five types:
Agglutinative-backed Foam
Adhesive-backed foamis a compression-blazon of weather-stripping, meaning that when the window closes against it, the foam compresses to seal gaps and block out drafts. It features piece of cake skin-and-stick application, and cuts hands with scissors. Just be certain to thoroughly clean the expanse around the inside of the window; the adhesive won't stick to dusty, muddy surfaces.
On double-hung windows, utilise adhesive-backed foam weather condition-stripping to bottom border of the lower sash, and to the top border of the upper sash. If you don't desire to apply the weather-stripping directly to the sash, stick information technology to the sill below the lower sash, and to the head jamb higher up the upper sash.

When compressed past the sash, the tubular conditions-stripping conforms to the space, effectively sealing out the wind. Some tubular gaskets have peel-and-stick agglutinative backing, while others have an attached metal or wood flange that must exist secured with nails or screws. If nailing, don't forget to diameter pilot hole first or y'all'll risk splitting the wood flange. Also, look for foam-filled tubular gaskets that take a spongy-foam core, which holds its shape better than hollow-cadre gaskets.
Spring Five-Seal
Spring V-Seal is a resilient polypropylene plastic or metal strip that's folded into a V-shape. It'due south known as tension-seal conditions-stripping because the 5-shape springs open, creating tension—and blocking drafts—betwixt the sash and window frame. Plastic V-seal can exist cut with scissors, but yous'll need aviation snips to cutting metal Five-seal, which comes in copper, aluminum, statuary and stainless steel. Also, the plastic blazon often has a peel-and-stick backing, while metal 5-seal must be nailed in place.

Felt is used as a compression weather-stripping around the within of double-hung, casement and sliding windows. Felt is affordable and like shooting fish in a barrel to install, merely it doesn't last as long every bit other types of weather-stripping.
Window Insulation Kits
Window insulation kits block drafts past sealing the unabridged window behind a large canvass of shrink-wrap plastic. The plastic is adhered to the interior window casing with double-sided tape, then shrunk drum tight with a blow dryer. Window insulation kits are very effective at sealing out drafts, merely go along in mind that y'all won't be able to open up the window until jump when you peel off the plastic wrap.
