How to Shop for Insulated Windows

Written by: Amy Whittle

Insulated windows are an essential part of an energy-efficient home. A well-made window will drastically reduce air leakage and condensation. Many states offer tax credits to update homes that currently have non-insulated windows. The windows dealer you work with should let you know if your state government offers any such incentives.

Choosing insulated windows

When choosing insulated windows, there are several things to look for. The most important characteristic is the U-factor of the window. The U-factor measures the energy efficiency of different doors and windows. If you’re familiar with purchasing insulation, a U-factor is comparable to an R-factor. In general, you should get the highest U-factor you can afford.

Once you have found several options with high U-factors, examine the tinting and glazing options. At minimum, your window should have two parallel pieces of glass with an air pocket between them. The air acts as an insulator between the two types of glass, decreasing any heat loss or heat gain. These types of windows, called double-glazed windows, are the most common type of energy efficient windows on the market.

Tinting, in particular, is something that you should strongly consider. Unlike tinted car windows, tinted insulated windows have only a slight tint that isn’t typically noticeable. This small color addition limits heat gain, keeping occupants seated directly under a window more comfortable.

Finally, consider the reputation of the company you’ll work with. A basic warranty should be offered with most windows, but you should be confident that the manufacturer will stay in business long enough to cover the full length of the warranty.

Installing insulated windows

Even a window with a high U-factor won’t provide ample protection against a poor installation. If you don’t have the right insulation for your windows, you’ll experience energy loss which will cost you move in energy costs in the long run. For instance, cracks around the window casing should be insulated and sealed to prevent air leakage.

For this reason, it’s recommended that you work with a licensed professional to complete the installation. If budget is a concern, consider hiring someone to complete the work in the late-Fall or early-Spring since those seasons are when contractors are often the least busy.

Insulated windows are an essential part of many modern homes. By installing a window with a high U-factor, you can prevent up to 30% of energy loss. This can potentially represent hundreds of dollars in savings on heating and cooling bills annually.
