Old or poorly insulated windows can make it difficult to maintain a comfortable temperature inside your home. Drafts, heat transfer, outside noise, and rising energy bills are all common signs that your windows may no longer be performing efficiently.
Windows are one of the most important components affecting your home's overall energy performance. Inefficient windows can allow heat to escape during colder months and let unwanted heat enter during warmer seasons. This causes your heating and cooling system to work harder, increasing energy usage and reducing indoor comfort.
