Light and Heat Part 1: Why Consider Them When Buying Windows

Light and Heat Part 1: Why Consider Them When Buying Windows

April 06, 2018

When buying replacement windows, daylighting and energy efficiency are some of the most important factors you need to consider. Some products are good at catching a lot of sunlight, while others are designed to trap indoor heat.

Renewal by Andersen® of Milwaukee discusses some of the best reasons why you should choose windows adept at doing both:

Sun Is Free and Healthy

Getting a generous amount of natural light makes an energy-saving and happy home. A profusion of sunlight brightens up your space at no cost, decreasing your dependence on artificial lighting. Studies show that daylighting helps beat the blues and increase productivity. Most importantly, regular exposure to sunshine is key to regulating your body clock, helping you get restful sleep every day.

The sun is constantly showering your home with a free and abundant source of energy. Apart from glazed entry and patio doors, the best way to harvest it is through windows with a high visible-transmission rating.

Excessive Solar Heat Gain Can Be a Drawback

The usual drawback of daylighting is excessive heat gain. If your windows lack invisible Low-E coatings, they would also let in the invisible portion of the solar spectrum. Using the sun to heat your home is useful during winter, but you can’t always say the same during the hottest months. Although you can open them to ventilate your room with external winds, doing so would make your valuables more vulnerable to damaging ultraviolet rays.

Excellent Thermal Insulation Saves Energy

Any experienced windows contractor would agree that high-performance fenestration products add value to your home’s complete thermal enclosure system. In addition to airtight seals, adequate insulation and reduced thermal bridging, windows with a low U-factor are paramount to using less energy for comfort.

But then again, you shouldn’t just buy the products with the lowest U-factor. In Milwaukee County, it’s imperative to choose windows with the right combination of U-factor and Solar Heat Gain Coefficient ratings to meet ENERGY STAR®’s requirements. Ideally, the most suitable products are those with a U-factor of 0.27 or less and any Solar Heat Gain Coefficient value. Although you’re allowed to use windows with a U-factor of 0.30 at most, the Solar Heat Gain Coefficient minimum changes whenever the U-factor increases.

Hear From Our Customers

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
