Types of Window Sealing Tapes
Foam-Based Sealing Tapes

Rubber-Based Sealing Tapes
Rubber sealing tapes are extremely durable and flexible. Built to withstand harsh weather, they’re ideal for exterior use in rainy or sunny conditions. They offer a long service life and stay flexible through temperature shifts.
All-Weather Sealing Tapes
These tapes are designed to handle year-round conditions—hot summers, freezing winters, or anything in between. Featuring heavy-duty adhesives, they form a lasting seal that keeps out drafts and moisture season after season.
Installation Guide
Surface Preparation
Before installing your sealing tape, start by cleaning the window frame thoroughly. Use a mild detergent and water solution to wipe away any dust, dirt, or grease, then let the surface dry completely.
Next, remove any old adhesive or tape residue using a scraper or adhesive remover. Proper surface prep ensures the tape bonds effectively and lasts longer.
Application Process
Measure the window frame and cut the tape to length with a utility knife, allowing for slight overhang. Begin applying the tape from one end, pressing it firmly into place as you slowly peel away the backing paper.
Use scissors to cut corners at 45° angles for a clean fit. Smooth the tape with your hands or a flat tool to eliminate air bubbles and ensure even adhesion.
Finishing Touches
Once the tape is fully applied, go over all seams and edges with firm pressure. Trim excess material carefully and inspect the corners. Add a second layer if necessary for reinforcement. The result should be a smooth, draft-proof seal around your window.
