Navigating Window Energy Ratings

Navigating Window Energy Ratings

March 07, 2024

Unlocking the potential for a more comfortable and energy-efficient home begins with choosing the right windows. In this guide, we’ll demystify window energy ratings and ENERGY STAR certification, breaking down key concepts to empower you to make the best choice for your home.

How Important are Window Energy Ratings?

For homeowners eager to boost their home’s energy efficiency and comfort, understanding the importance of window energy ratings is key. These metrics, including U-factor and Solar Heat Gain Coefficient (SHGC), are indicators of a window’s effectiveness in insulation, heat blockage, and minimizing air leaks. Renewal by Andersen takes pride in offering windows that not only meet but exceed ENERGY STAR specifications, representing the pinnacle of energy-efficient window performance. 

Selecting windows with good energy ratings can dramatically decrease the reliance on heating and cooling systems, ultimately reducing expenses. These ratings equip homeowners with the knowledge needed to choose windows that align with their region’s climate, enhance indoor comfort, and safeguard interiors against UV damage, all while yielding substantial energy savings. Essentially, window energy ratings serve as a benchmark for evaluating a window’s efficiency. 

U-Factor Insight

The U-factor rating is key to understanding a window’s insulation quality. A lower U-factor signifies better heat retention capabilities, essential for maintaining a warm and comfortable home during the cooler months. At Renewal by Andersen, we know how important it is to be prepared for harsh Wisconsin winters, which is why our windows are made for superior performance in even the most frigid temperatures. 

Solar Heat Gain Coefficient (SHGC)

The SHGC rating balances the amount of solar heat a window allows into your home. Natural sunlight keeps your home bright and warm, but too much sun can make your home feel like a sauna. Our ENERGY STAR-certified windows admit the perfect level of sunlight, warming your home naturally while preventing excessive heat. 

Air Leakage

A critical aspect of window performance is air leakage, which measures the window’s ability to seal outside air. In cooler climates, air leakage brings drafts that can chill you to the bone. Our windows boast low air leakage ratings, meaning they effectively block unwanted drafts, making your home more comfortable without having to crank up the heat. A tighter window seal means your home will stay cooler in the summer and warmer in the winter. 

Beyond Energy Efficiency

UV Protection

Renewal by Andersen windows stand out for their ability to block harmful UV rays. This protection is crucial not only for preventing the fading of interior furnishings but also for guarding against the health risks associated with UV exposure. Our ENERGY STAR-certified windows feature special coatings that block the majority of UV radiation while still allowing your home to be illuminated with natural sunlight. So you get all of the benefits of the sun with none of the bad stuff. 

Noise Reduction

The hustle and bustle of the outside world can disrupt the tranquility of your home. Our windows are constructed with materials and techniques designed to significantly reduce noise intrusion, offering you a peaceful indoor environment. This feature is particularly beneficial in urban settings, where external sounds can be a constant disturbance. 

Conclusion: The Path to an Energy-Efficient Home

While understanding energy ratings can seem complicated, they are crucial for any homeowner looking to make informed decisions about their home improvements. Renewal by Andersen’s dedication to providing windows that excel in energy efficiency, comfort, and design ensures that when you choose our products, it is a step toward long-term benefits and savings.

Hear From Our Customers

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.

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!!!

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.
