Where to install L-bracket
« on: March 16, 2012, 10:39:45 PM »

I would like to install the magnaseal windows on my windows and would like advice on how to handle the window structure I have. I have posted an image of the left lower corner of the window here: http://tinypic.com/r/9tgyah/5
The rounded inside edge seems like a problem since I won't be able to attach the L-trim securely around it.
Any advice would be welcome.
Thanks.

It does not look like you have a lot of air gap potential since you have nothing to compare depth of the seal in the image.
You are going to have to install either inset of the round which means the acrylic will be next to the round of the corner or your going to have to use a mix of flat stock with L-frame for a flush mount system..

also your windows look poorly sealed from the image..you will need to fix this problem. We need dead air space in order to achieve reduction.

You will need to contact me direct for flat stock material.

The depth from inner edge of the round to the window is little over 2 inches. The upper half of the window would have a 4 inch air gap.
Based on an energy audit, looking at the window with an IR camera, it is pretty well sealed against air infiltration. Of the four windows that have this type of construction this one is actually the quietest.

If that is the case then you are in good shape, install the L-frame as shown in the lower diagram on this page.

you will end up with almost 2" dead air space.. for best results use 3/8" acrylic.
