Cut Energy Consumption with Proper Windows and Doors

When you're looking for a window manufacturer West Virginia, then you have to look at Doorwin

Windows and doors have a huge impact on your home's energy consumption

They account for more than half of the air leaks in the average home, and they are the single largest source of heat loss or gain

It doesn't take much to make your homes more energy efficient. Here are some simple things you can do to upgrade your windows and doors

Replace older single-pane windows with new double-pane windows or storm doors with low-E coatings that reflect heat back into your home and help keep cold air out during winter months

Replace older wood or metal exterior doors with newer vinyl ones with upgraded weather stripping and insulating materials

Install awnings over exterior doors to shade them from the sun during summer months

Improperly installed, older or damaged windows and doors can lead to significant energy loss

This is especially true if the home is poorly insulated. Energy efficiency can be improved by replacing old, poorly functioning windows and doors with modern ones that are more energy efficient

A good way to measure the potential for energy savings is by comparing the existing window's U-factor rating with the new window's U-factor rating. The U-factor measures how well a window blocks heat flow through its glass pane. The lower the U-factor number, the better it resists heat transfer and therefore reduces energy loss from your home. If a new window has a higher U-factor than an existing one, it will not save as much energy as you might expect because it will allow more heat transfer than your current window does

Save money by investing in the right windows and doors for your home

f you*re ready to make your home more energy efficient, upgrading your windows and doors is a great place to start

Choosing the right windows and doors can help you save money on energy bills, reduce air leakage and improve comfort levels in your home

A well-insulated window or door can help keep your home comfortable year-round. It will also help protect your furniture and belongings from excessive heat loss or gain in the winter and summer months

When it comes to energy efficiency, new windows and doors should come with a U-factor rating of 0.30 or lower for most climates 〞 and even lower if you live in an area with extreme temperatures, such as Alaska or Minnesota. A good window or door will also have an SHGC (solar heat gain coefficient) rating of 0.25 or lower.
