Is it time for new windows and doors?
When it comes to making your home more energy efficient, the case for installing new windows and doors is open and shut.
The U.S. Department of Energy estimates that heat gain and heat loss through windows and doors are responsible for 25%–30% of residential heating and cooling energy use. They recommend taking steps to reduce the energy loss as this can make your home more comfortable and save you money on energy bills.

Even the most energy-efficient window must be properly installed to ensure energy efficiency and comfort. If your windows are not installed by trained professionals according to manufacturer’s instructions your warranty may be void.
Window installation varies depending on the type of window, the construction of the house (wood, masonry, etc.), the exterior cladding (wood siding, stucco, brick, etc.), and the type (if any) of weather-restrictive barrier.
Windows, flashing, and air sealing should all be installed according to the manufacturer’s recommendations to perform correctly.

New exterior doors fit and insulate better than older types. If you have older doors in your home, replacing them is a good investment, resulting in lower heating and cooling costs.
When selecting doors for energy efficiency, it’s important to first consider their energy performance ratings in relation to the L.A. climate and your home’s design. It’s critical to evaluate both the ENERGY STAR label and The National Fenestration Rating Council (NFRC) label. The NFRC label helps you compare energy performance ratings of doors. The label shows the solar heat gain coefficient (SHGC) for the door. In Los Angeles, where we require more cooling, a low SHGC is critical.
Patio doors bring other factors into play. Because glass is a very poor insulator, models with several layers of glass, low-emissivity coatings, and/or low-conductivity gases between the glass panes are a good investment.
With all those issues to consider for both doors and windows, there’s one clear choice for help.
