What Makes it a Wheaton Window ?
-
Incredible Thermal Performance
Our windows are the most energy efficient in the industry. The U.S. Department of Energy recommends windows with a U-factor measuring thermal conductivity of .30 or better (the lower the number, the more efficient the window).
Our Starmark composite window delivers U-ratings as low as .15, which is 45% more efficient than industry averages. Depending on the glass options you choose, you can dial-in your energy savings. Even our most affordable vinyl windows delivers a U-factor (.28) far lower than government guidelines.
-
Lifetime Fully-Transferable Warranty
That’s right! If anything goes wrong with your windows, we will fix it for free for as long as you own the home. Plus the warranty can be transferred to the new owners when you sell your property. We take out the risk of buying replacement windows, and we back it up with 65 years of continuous service to Washington areas homeowners.
-
Locally Manufactured for the Mid-Atlantic Region
All our windows are manufactured locally in the Mid-Atlantic area, specifically for local climate conditions. You get windows optimally designed to keep you warm in winter and cool during Washington’s hot Summers! Engineered to standards first developed in Europe where energy costs are much higher than in the U.S., you will not find a better combination of value and performance anywhere.
-
Custom Fit
Every window we sell is custom-sized to fit your home. We never try to fit a stock-size to fit your opening since this can lead to air infiltration and less energy efficiency. Many contractors will try to use standard sizes because it costs them less money. But you will pay in the long run because your windows will never delivered the promised energy savings.
-
Certified Master Installers
All of our installers are factory-certified and you can be sure that they produce results second to none. Field and classroom instruction is supplemented with periodic testing and evaluation as part of the Wheaton Master Certified Installation Program.
-
High Condensation Resistance
Because of their energy efficiency, some replacement windows are prone to moisture condensation, particularly when humidity levels in the home are high and there is a large discrepancy between inside and outside temperatures. Wheaton windows have condensation resistance ratings of 62 to 75. (The higher the number, the less condensation). Typical replacement windows are rated at 55 or lower.
-

Plus, optional interior laminates can be painted or stained to complement any decor. Also choose from upgraded hardware in popular brushed-nickel finishes.

How much energy will I save?
Experts indicate that inefficient windows are one of the single biggest contributors to energy loss in your home. Many of our customers report energy savings of anywhere from 15% to 30%. However, your results may vary depending on any number of factors, including the insulation in your walls and attics, the orientation of your home (Northern exposure, Southern exposure, etc.,) and average outside temperatures year to year. No reputable company can accurately “guarantee” particular energy savings because there are so many variables to consider and you should be wary of companies that guarantee savings. Read the fine print and you’ll see that what they promise is generally far less than meets the eye!
What about government tax incentives?
New government tax credits allow up to $200 in energy tax credits for windows that meet Federal guidelines. All Wheaton windows meet or exceed these standards. Consult your accountant for specific tax advice.
