Windows FAQs, answered by experts

Yes, storm windows should be tempered. According to the International Association of Certified Home Inspectors, tempered glass is stronger and can withstand temperatures higher than laminated glass. Tempered glass is important for storm windows because it protects against outside elements and household accidents by not producing sharp, jagged pieces when it breaks or shatters.

If the existing frame around the window sash is completely structurally sound, it's possible to save money by swapping out the sash for a new one instead of getting a new window. Keep in mind that it will be necessary to find a new sash that perfectly matches your existing window structure. In general, consulting a window pro to help you find the right match is the best way to ensure you're doing this project correctly.

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

The purpose of an awning window is to let fresh air into your home without taking up too much wall space. They’re ideal if you live somewhere that gets a lot of rain because their design helps prevent rain from coming into your home. In bathrooms, awning windows also help with ventilation but don’t compromise your privacy.

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.
