The lifespan of exterior doors varies depending on factors such as the material, climate, and maintenance. At Clera, our steel and fiberglass doors are built to withstand the elements and last for years. We also offer a lifetime warranty on our products.
Exterior doors can open inwards or outwards—it depends on your preferences and the building code regulations in your area. However, it's important to ensure proper installation to avoid any issues with function or security. That's where The Clera Windows + Doors team can help determine which option is best for your home.
Measure the height and width of the door frame at the inside face of the exterior trim. Then, measure the depth of the door frame. It is recommended to have a professional installer like Clera measure and install the door to ensure proper fit and installation.
Exterior doors are typically installed by professional contractors or experienced carpenters. Many window and door companies like Clera Windows + Doors offer installation services as part of their product offerings. Choose an installer with the necessary expertise to properly install the door to ensure optimal functionality and durability.
Less than half of the sun’s energy is visible. Longer wavelengths beyond the red part of the visible spectrum are infrared, which is felt as heat. Shorter wavelengths, beyond purple, are ultraviolet (UV). When the sun’s energy strikes a window, visible light, heat, and UV rays are reflected, absorbed, or transmitted into the house. Low-e glass contains transparent metallic oxides that reflect up to 90 percent of the harmful UV rays.
