How Installing Energy-Efficient Windows in Glen Rock Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Save money on energy bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
• Decrease your carbon footprint: In Glen Rock, you can reduce your indirect greenhouse gas emissions by about 206 pounds per year when you install energy-efficient windows.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.

How Much Do New Windows Cost?

It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Glen Rock homeowners $285+ a year when replacing single-pane windows.

Requesting free quotes from multiple providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

When it comes to window installations, there are typically two types that your installer will offer: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the old frame. So, instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you choose what’s best for your needs. In Glen Rock, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.
