Ventura Vinyl-Clad WindowsWhen you comparison shop among our competitors—and you definitely should—you will probably be offered their "best" window as compared to our "best" window. But it's an apple-to-oranges comparison—here are the facts:

Our best vinyl-clad window is the Grandura/Simonton. It's manufactured by Simonton, distributed by Amcraft, and they have collaborated with us to guarantee it for ten years—both materials and labor. It's an interesting business story, one that we're proud to be part of, and we talk about it here.

But for the moment suffice to say: Nobody in the world makes a better vinyl-clad window than Grandura/Simonton, and there's no window with a comparable guarantee.  Their "best" is in no way as good as our "best," and we have the hard data to prove it.

So if you want to make apple-to-apple or orange-to-orange or mango-to-mango comparisons, you should compare their "Best" to our Ventura line of windows, which is also distributed and backed by Amcraft.  

Ventura are excellent vinyl-clad replacement windows. They might be best for you depending on your budget, your personal goals, how important color-choices are to you, how long you plan to keep your home, etc.

Like Grandura, they are ENERGYSTAR-rated and have earned the AAMA Gold Label Certification, which is the highest level of testing for quality and performance. Ventura features & benefits are shown in the photo nearby.
