Do:

 –Have a licensed, certified contractor inspect your house before you purchase anything

A qualified contractor will be able to tell you if there’s structural damage in the home that could hamper a new window’s efficiency.  Problems like deteriorating wall systems or foundations, inadequate insulation and cracked or rotted structural materials surrounding windows can compromise the replacement window’s performance. They should be taken care of before installation so new windows can easily fit into the house’s framework and maintain the right interior heating & cooling retention.

 –Find a window product with the correct U-factor for the climate zone where you live

The U-factor is a measurement of a window’s resiliency to heat flow that helps with insulation. Try to find the lowest U-factor that’s available in your climate zone.

 –Select the right glazing choice for your needs

Glazing is similar to tint but does it does more in that it also insulates.   You should look for a glazing that offers a bit of tint for more privacy and to protect against heat. However, it should also reflect light adequately and reduce glare.  It’s not hard to find a happy medium between these two qualities as there are a variety of glazing options in the marketplace.

 Don’t:

 –Overlook the importance of the frame type

A window’s frame composition can also influence its efficiency qualities. Popular window frame types on the market include vinyl, aluminum and fiberglass. And while all are energy efficient (the vinyl and composite windows rate identical to wood) they’re not necessarily better-rated than traditional wooden frames.  Newer materials offer durability and ease of maintenance but it doesn’t guarantee they’ll have greater efficiency.  You just have to determine which factors are the most important to you in your search.

 –Buy from the first company you like

After you’ve made the decision on the type of replacement window you want, it’s important to investigate all your options. Don’t presume that the first brand that looks good is the best one for you. With competitive pricing available from companies around the country, it’s easy to shop around and do your homework for the best option that suits your needs. Check out the company and its time in the industry. Also get reviews on products, warranties and track records with customers.
