  • Why Choose Energy-Efficient Windows?

The term ‘energy-efficient’ may sound expensive to some, but it’s something that can actually save you money. If you’ve been looking for a sign to get modern windows, here are reasons why choosing modern, energy-efficient units for your home upgrade is the right choice.

Energy-Efficient Windows

What Makes a Window Energy-Efficient?

Exterior renovation contractors say there are different components that make a window energy-efficient. This can be low-E glass, gas fills, multiple panes, quality frame materials, and warm edge spacers. A properly insulated energy envelope should be able to prevent the thermal transfer or heat leaks and sustain consistent indoor temperatures, reducing the house’s heating and cooling requirements.

The Benefits of Energy-Efficient Replacement Windows

  • Less noise pollution. As mentioned, high-quality windows have glass panes with inert gas within them to reduce sound transmission. Having energy-efficient windows with two or more panes is significantly helpful if you’re having trouble sleeping at night, or if you have kids and pets living in a busy area.
  • Improved natural lighting. Most energy-efficient windows have coatings blocking UV rays and heat from the sun, allowing you to have direct sunlight heating up your home even during cooler seasons.

  • Energy savings. Half of an average household’s annual utility costs are spent on heating and cooling systems alone. So, if you’re calling for a chimney repair or skylight installation, maybe it’s time to also consider that window replacement as well to improve indoor comfort while being at ease with your monthly utility dues.

  • Increased living space comfort. Your existing windows are highly prone to air leakage and likely have poor insulation. With modern energy-efficient replacement windows, you can guarantee a tighter seal and superior insulation. This enables properties to have a comfortable temperature.

We were so happy with the roofing, siding and pertego job PJ Sullivan did for us. We couldn’t have asked for a better company to do this for us. Pete was very attentive and visited our home at least 3 times a week and that was important for us.
