Duluth, Minnesota Window Replacement

Last updated on 11/15/2019

Duluth window replacement can be an especially important project for homeowners to undertake in this area of northeastern MN, as the temperatures can be pretty cold for many months. By installing Minnesota replacement window units and replacement glass in your home, you'll find that your house is better able to deal with the tough winter winds. The new window products can greatly cut down on any drafts that may occur, leaving your home feeling more comfortable.

By undergoing a Duluth window replacement project, you'll also end up allowing your furnace to run less, which will save you some money over the long run. If your replacement window frames do a good job of keeping the drafty winter winds out of your home, it won't be as cold in your house, and you'll use less fuel keeping your home warm. So, not only will your home feel better after a Duluth window replacement project, but it actually will be warmer, too.

Using Coated Replacement Glass

With low-e glass in your Duluth window replacement products, you'll end up maintaining a warmer home, too. Low-e, which is short for low emittance, is a type of coating that can be used with the glass in your window frames. This coating is primarily designed to prevent sunlight, and its infrared rays, from penetrating the glass inside homes in the summer time, which can cause it to heat up in an uncomfortable manner, especially in warmer climates.

However, the low-e glass in your Duluth window replacement products also can give your home a better feel in the winter time. Although the low-e glass will block some of the infrared rays from the sun from entering your home in the winter time, which can provide some warmer conditions, the primary purpose of the low-e glass in the winter in MN is to do a better job of efficiently keeping the heat inside your home. The heat from your furnace will have a more difficult time leaking and seeping through the low-e glass to the colder conditions outside.

Another type of coating on Duluth window replacement products involves blocking ultraviolet rays from the sun as they try to enter your home during the summer. These UV rays can be problematic because they can cause your furniture and wall paint to fade, which obviously isn't good for your home. However, the coatings protect your home from these problems, which adds greater value to the replacement window products that you can purchase.

Finding a Passive Solar Window

One of the interesting aspects of the coating on the replacement glass products is the way that these pieces of coated glass allow the light from outside to enter your home, while blocking differing levels of the heat from the infrared rays. For example, if you're using a double pane replacement window or even a triple paned glass window unit in your home, you should receive a good rating on the energy efficiency of your glass. Much of the heat that your furnace is generating inside your home will stay inside your home with the double pane design.

If you want to make use of passive solar heating in your home, while still using Duluth window replacement products, you have the option of varying the level at which the low-e glass will block the infrared rays from the sun. Some low-e glass that has a high solar gain rating will allow almost as many infrared rays into the home as it allows light rays into the home. This will generate the heat necessary for a passive solar system that may work well in Duluth winters. However, you also can select a low-e coating that has low or moderate solar gain ratings, blocking more infrared rays.

Warmer Homes in Duluth

The Duluth area of Minnesota is well known as being extremely cold during the winter time. Night time conditions in January see average temperatures of below zero readings here. Spring often comes late to Duluth, as below zero temperatures have occurred here into April. Still, Duluth is a city of 86,000, and it has a lot to offer its residents. This city is known for far more than cold winters.

Duluth is located along the north shore of Lake Superior. This city rests on the Minnesota and Wisconsin border, and it is considered as a twin city to Superior in Wisconsin. Summers are very enjoyable in this area of Minnesota, thanks to the cool conditions created by the winds from Lake Superior.

Residents here have quite a few options for finding installers who can perform Duluth window replacement projects. Because of the cold winters, some Duluth window replacement companies will attempt to sell triple pane products to the residents here. Although these types of frames can be much more expensive than double pane products, they will provide valuable energy efficiency benefits in this area of MN.
