Question: 1 / 400

What effect does proper sealing have on window installations?

It increases the weight of the window

It reduces energy efficiency

It creates air leaks

It improves energy efficiency

Proper sealing of window installations is crucial because it significantly enhances energy efficiency. When windows are sealed correctly, they prevent air from infiltrating or escaping, which helps maintain consistent indoor temperatures. This means heating and cooling systems do not have to work as hard to compensate for energy loss, ultimately leading to reduced energy costs for homeowners.

In addition to energy savings, a well-sealed window installation contributes to a more comfortable living environment by minimizing drafts and fluctuations in temperature. It also helps to protect the interior of a home from moisture intrusion, which can lead to damage and mold growth over time. Thus, the correct emphasis on sealing directly correlates to improved overall energy efficiency in window installations.
