We tend to offer a much wider range of features and options than most companies so we’ll have a wide range of efficiency packages available. Generally U-Factors are available down to 0.19 (lower is better when it comes to U-Factors).
We’ll also have windows with very low air infiltration rates, down to 0.01, and windows with a range of Solar Heat Gain Coefficients or SHGC to solve any problem.
If you’re concerned about sound transmission we have options with great STC ratings and we can also review options with outstanding Condensation Resistance ratings too.
Once you request a copy of our window pricing through the website our window experts will email you information on several common efficiency packages including all relevant ratings. We try not to overwhelm you with info but if you want any more detail on anything just write back to let us know. We can help with anything and we have a solution for almost everything.
