replacing windows with glass blocks?

Posted by tim52317 (My Page) on

The basement window of my 1910 house are shot and I want to replace them this summer. I have 6 of them in all and plan on buying replacements from the local Home Center and build frames for them. One of these windows is under our wrap-a-round porch and one other is under the steps that lead from a french door into the back yard.

I am think of replacing these two with those glas blocks. I think I would most likely be able to complete this from the inside and not have to crawl under the porch. I thought of eliminnating them all together, but they do supply some light. The basement is unfinished and these are the windows are about 24X36.

Anyon ehtink this is a bad plan? Should I just replace them all the same. Any pros and cons you can think of would be of help. Maybe the glass block thing does not work to replace a window I usally see them in bathrooms.

Great idea.

However, you (or someone) still has to get under the porch to help install them and do the final caulking.

when we poured our basement walls we left spaces for glass blocks 24 x 36. We doubled these for security purposes. We like them, the blocks brought in more light than they did when open. They reflect light in the entire basement. Might be a bugger for you to get to the area to replace, but I think you will be pleased.

Does your basement have 2 entrances/exits? If not I would want windows that open just in case you're ever down there and a fire breaks out.

Goodness, I live in a basement apt. and I can't imagine not having windows just to be able to look at the sky once in a while. My mom has glass blocks in her house and everyone hates them. They let light in but you still feel claustrophobic. I wouldn't use them in a basement for anything in the world! Also for the right barometric pressure to support your home air is needed to come in and out. Open windows in the summer help keep the basement dryer too. I'm an engineer so from a structural perspective, I wouldn't do it either.

RE: replacing windows with glass blocks?

I don't know if you've made a decision on what to do yet, but I had been looking around for similar solutions for my garage. The house is built into a slope with the garage tucked underneath. The one window in the garage is an aluminum slider roughly at outside ground level along one side (near ceiling of the garage), and I think it presents a security problem. I have a curtain on it now so that no one can see in, and there is vegetation blocking the view from outside, but I still think about that when I'm here alone.

I want the light from it but not the security concern. There are other openings to the garage -- a door to the house entry and the garage door itself. Anyway, I was digging around online and found a manufacturer of replacement windows made from acrylic block. They come in fixed and openable forms; I'm attaching a link that I hope works. I'm not in a position to take this project on now, but it's on my back burner.

Assuming that the existing windows were properly framed, what is the structural concern, mariascottage? Particularly for windows under stairs/decks, I can't imagine view is an issue.
