Switching to Energy Efficient Windows in Portland, OR

All homes lose energy, especially through the windows. They are one of the weakest links in the exterior envelope of your home. In fact, you can lose a third of your heat every year. But when you invest in energy efficient windows, you can conserve energy and save money. There are a lot of factors to consider if you want to improve efficiency. Choose these window features wisely and you could save money every year.

1. Frame Material
The first step in choosing energy efficient windows is picking the right material for the job. When it comes to reducing heat transfer, any one of these options can work. Wood window frames are elegant and warm. They are also thermally resistant. But these windows do come at a higher price and will require more maintenance over time. Vinyl window frames are a more affordable option. They provide excellent energy efficiency and require little maintenance. Aluminum windows are another choice. The material is light, strong, and durable. It can hold expansive pieces of glass. Unfortunately, the material is not as efficient as the other materials. Fiberglass is a good mixture of all the other options. It is paintable, durable, strong, and efficient. This is a low maintenance options that often costs the most.

2. Window Style
The next step in choosing energy efficient windows is finding a style that will serve you well. Picture windows have no breaks and will give you the best seal against air and moisture leaks. Second comes casement and awning windows, which close and lock tightly, sealing out the elements. When the wind blows against these windows styles, the seal only tightens. Next comes sliding windows, both horizontal and single or double-hung windows. These windows styles are excellent for ventilation and while they do insulate against air leaks, they are not as impenetrable as other styles.

3. Glazing
Just as important as window material and window style is the glass you choose. And as far as efficiency goes, glazing is one of the most important aspects of your windows. You will want double or triple pane glass for maximum efficiency. And you can choose an argon or krypton gas filling between the panes of glass. These are odorless, colorless, and nontoxic, but have more density than regular air, which is how they boost insulation. You might also consider window tints or low-e coatings. This will improve the Solar Heat Gain Coefficient (SHGC) and the U-Value on your window ratings.

4. Spacers and Thermal Breaks
In the past, double pane windows were welded along the edge of the frame. But manufacturers discovered that widening the gap improved insulation. Unfortunately, the welded seam couldn’t hold. So instead, manufacturers started to use rubber and steel to act as spacers. These bond to the glass and will hold, even with expansion and contraction. Most vinyl, aluminum, and fiberglass window frames also have empty chambers the installers fill with foam to boost insulation. These thermal breaks increase strength, stability, and energy efficiency.
