Adhesive-backed sealant applied to doors and windows forms a barrier against drafts, moisture, and pests. This simple barrier can range from thin foam tape to more substantial rubber or silicone strips.
Creating a tight seal offers significant advantages, including reduced energy consumption through minimized heat loss and gain, protection against water damage, and improved indoor air quality by blocking dust and pollen. This practice has evolved from rudimentary methods like stuffing fabric into gaps to the sophisticated, readily available solutions seen today. The effectiveness of this sealing method contributes significantly to building comfort and efficiency.
