Review of the Marvin and Integrity Energy Efficient Windows [Video]

The Marvin and Integrity windows - both under the Marvin brand - are very energy efficient, and both offer a number of products that meet criteria for federal and state tax credits

The Marvin brand has two lines of windows and doors: Marvin and Integrity. The Marvin line is a high end, made-to-order, custom window and door line made entirely of wood or aluminum cladding. The Integrity line is a pultruded fiberglass product. These Marvin lines are celebrated for their beauty, energy efficiency and durability. Many of these windows qualify for energy tax credits. In addition, they are manufactured using sustainably harvested wood, and excess shavings and waste wood materials are used to heat the manufacturing facility in Minnesota.  Video below.

The Marvin line is a high end made to order custom window and door line. Its an all wood or aluminum clad product that is available in a variety of custom shapes and sizes. If you can dream Marvin can build it for you. Its a high end premium grade window patio door and entry door product. The main difference between the Marvin and Integrity lines is that the Integrity line utilizes a pultruded fiberglass material called Ultrex which is a very durable energy efficient strong green material that is either available with the wood interior or an all fiberglass window.

Both the Marvin and Integrity lines are very energy efficient. Both lines offer a number of products that meet criteria for energy efficiency tax credits. All the wood used in both lines is sustainably harvested. There are various Marvin entry doors that are FSC certified. The Integrity line is made of fiberglass, which is made from silica sand, an innumerable resource. The windows and doors in this line are very durable and very strong, so they can perform for a long period of time.

In addition to creating an environmentally friendly product, Marvin also operates its factories in a sustainable manner.  For example, Marvin heats its main facility in Minnesota using all the shavings and saw dust that are left from the window manufacturing.

The R-Value of the Marvin and Integrity lines depends on the type of window manufactured, the glazing and the various options selected. The most energy efficient Marvin line has tri-pane glazing, standard low-E2, low-E 366. The Integrity line has some of the same glazing options as well. With the Integrity line, since the fiberglass is made out of a sand material similar to what the glass is made out of, it’s going to expand and contract at the same rate as the glass. So in cold winters or hot summers, when you have a lot of expansion and contraction, you will have fewer stress cracks or seal failures, so these windows are going to perform and maintain their energy efficiency for a longer period of time.

Marvin builds premium products, whether it’s the Marvin line or the Integrity line. The products perform over a long period of time, and they are also beautiful. So by buying Marvin and Integrity windows you are putting beautiful products into your home that are going to perform and last for a long time.
