Sealing Draft Windows: A Comprehensive Guide

Understanding Draft Windows

Draft windows are openings in a building’s exterior walls that allow cold air to enter and warm air to escape. These openings can be a significant source of heat loss in the winter and heat gain in the summer, leading to increased energy bills and reduced comfort. Sealing draft windows is an essential step in reducing heat loss and energy consumption.

Why Seal Draft Windows?

Sealing draft windows is crucial for several reasons:

Energy Efficiency: Draft windows can account for up to 30% of a building’s total energy consumption. By sealing them, you can significantly reduce heat loss and energy bills.

Comfort: Draft windows can make a room feel colder than it actually is, leading to discomfort and reduced indoor air quality.

Safety: Draft windows can also pose a safety risk, as cold air can enter through gaps and cause carbon monoxide poisoning.
