Sealing Tape for Doors and Windows

Winter is on the way again an along with it the cold wind that seems to penetrate every door and window in your home. You can remedy this problem by installing door and window sealing tape around any replacement exterior windows and doors to prevent air infiltration. A good quality weather sealing tape creates a permanent sealing around windows and doors to keep out air drafts, water and vapor from entering your home around doors and windows.

Installing door and window sealing tape will go a long way in helping to keep homes warmer and prevent black mold by stopping moisture from entering the home.

Ideally door and window sealing tape should be installed during the installation process. Unfortunately many home builders omit this step leaving the home owner to resolve cold air infiltration around doors and windows or pay the high cost of wasting energy cost to heat the home.

It’s an easy DIY project to installing door and window sealing tape when you are installing a replacement door or window. Simply cut a piece to length and peel the back paper off while rolling the sealing tape into place against the wall sheathing before installing the door or window. For windows the tape should overlap the nailing flange. The process is similar for doors. All four sides of each door and window should be taped.

The best door and window sealing tape on the market is the Butyl Hybrid formula. It is a new BT25XL door and window sealing tape that provides maximum adhesion even in extreme temperatures. It also has increased adhesion on difficult to adhere sheathing such as OSB. The tape forms a permanent seal around doors and windows that prevents air and moisture leaks. Moisture intrusion that causes black mold is eliminated. The tape can be installed and left exposed for 120 days without any UV degradation. It is also the only flashing tape that has passed a hurricane level windblown rain test.

The BT25XL door and window sealer should not be used in conjunction with solvent based caulk or with flexible PVC based membrane material. In addition, the door and window sealing tape should be tested with the wall sheathing for adhesion. If there is inadequate adhesion, the wall sheathing surface can be primed with a spray adhesive before applying the sealing tape.
