Vinyl Replacement Windows

Is it AAMA policy to measure from drywall to dry wall instead of brick to brick to get measurements for new windows? That’s what the company manager said when I sent the rest of the window back. By measuring in this fashion, I have an INCH gap ALL around the outside of my windows. The company said they fill in the gap with fiberglass insulation and then cover the space with a vinyl trim and a bead of caulk. This much space between the window and the framed in space seems unbelievable. It seems to me that the window was measured wrong for the space. I thought there should only be an eighth or a forth inch space between the window and the opening. I only allowed them to put in 2 windows, temporarily, before I said stop! I had to get advice on this. I DESPERATELY NEED YOUR ADVICE!! The windows otherwise have all the needed R value, e- glass, energy star rated, etc. It’s just that space AROUND the window that is causing me to lose sleep.

I could find nothing in the Simonton window brochure that helped me with my question.

I'm not familiar with the AAMA requirements for replacement windows, but I agree that 1" seems like an awfully large gap.


Most window manufacturers are pretty good about technical support for their products. I suggest that you take a few good, clear pictures of the installation and send them to Simonton and ask for advice.
