At Windows USA®, we love to create amazing windows that inspire imagination and excitement in changing how your home looks and feels with a focus on making sure that each product is individually designed and crafted with a promise to exceed your expectations.
Windows USA windows are ENERGY STAR certified for South-Central and Southern climate zones. According to ENERGY STAR, “Replacing old windows with ENERGY STAR certified windows lowers household energy bills by an average of up to 13 percent nationwide when replacing single-pane windows. Lower energy consumption also reduces greenhouse gas emissions from power plants and homes.”
According to the IRS’ Energy Efficient Home Improvement Credit program, “if you make qualified energy-efficient improvements to your home after Jan. 1 2023, you may qualify for a tax credit,” which, for windows, is set at a maximum of $600 per year and for sliding glass doors is set at $250 per door per year.
The state of North Carolina released its version of the Home Energy Efficiency Rebate (HOMES) program in January 2025. Some rebates may be stackable with the federal credit; be sure to review all requirements and investigate to ensure that you qualify and apply correctly.
Raleigh’s unique climate demands windows that can handle both hot summers and cold winters. According to the National Oceanic and Atmospheric Administration, average temperatures range from 30 °F to 52 °F in winter and 73 °F to 94 °F in summer, although extremes (+10 °F higher and –30 °F lower than normal) have been recorded. To protect against those extremes, all Windows USA windows have multi-chambered frames and sashes to create space that prevents thermal transfer, creating one of the strongest vinyl windows available, and an innovative sash-interlocking system creates a strong continuous seal to resist air and water infiltration beyond industry standards.
Additionally, according to the National Centers for Environmental Information, the Raleigh area generally receives between 40 and 60 inches of precipitation annually, making it critical that your windows and patio doors are sealed from the elements—just like Windows USA’s innovative sash-interlocking system, Intercept® Ultra airtight spacer, and strategically placed “weep holes” that let exterior water drain out, keeping water where it belongs: outside.
According to the CDC, the Raleigh area, and North Carolina in general, has an Average Daily Dose of Ultraviolet (UV) light on the higher end of their scale versus other states in the continental United States.
According to the International Ultraviolet Association, ordinary window glass allows UVA light to enter your home. And the Skin Cancer Foundation says that UVA rays are a main cause of premature skin aging.
Ultraviolet (UV) wavelengths can penetrate solid surfaces, significantly damaging most materials that receive overabundant exposure. Vinyl and other materials can suffer undesirable mechanical, physical and chemical degradation from solar radiation, leading to cracking, chalking, color changes, and the loss of physical properties without protection. UV light can also damage furniture, fabrics, flooring, artwork, and photos.
Windows USA windows and patio doors have a UV inhibitor added to ensure the vinyl color will not fade, flake, or peel, even under extreme conditions. The glass is triple-layer coated and:
The dramatic comfort improvement from windows with warm glass surfaces also means the relative humidity of indoor air can be controlled properly. Proper humidity levels improve comfort and promote a healthier living environment.
Raleigh residents should also consider daily sun path relative to window orientation, and consult the U.S. DOE Consumer Guide to Energy-Efficient Windows to determine any special glazing requirements.
Unfortunately, Raleigh and Wake County experience a notable number of tornadoes. According to the National Weather Service Storm Prediction Center (SPC), different areas in North Carolina have recorded high tornado counts over the past 35 years. No window can protect against all tornadoes—certainly not a direct hit—but properly selected windows and patio doors help guard against extreme weather and temperatures.
Generally, according to the U.S. EPA Air Quality System (AQS), air quality across most of North Carolina is very good, with some areas of slightly elevated particulate matter in Raleigh specifically. Windows and patio doors with airtight seals help mitigate the risks of poorer-quality air. Windows USA products include Intercept® Ultra airtight spacers and an innovative sash-interlocking system to resist air and water infiltration beyond industry standards.
According to the U.S. Department of Transportation, North Carolina generally does not have high levels of noise exposure (aviation, highway, and rail) compared to other areas of the country—except larger cities like Raleigh, which do show higher levels. Your distance from airports, major roads, and rail lines will vary, affecting noise pollution at your home. Noise pollution “adversely affects the lives of millions” and “has direct links to health,” according to the EPA. Enjoy a quieter home with our double-pane windows that effectively block outside noise, perfect for Raleigh’s bustling neighborhoods.
