Yes, it is very easy. You will need to put new 1x4's around the inside of your window frame, get some good (expensive) calk, and your in business. You home improvement store will have everything. Blocks, block ties, frame ties, and morter. You can not get blocks where 4 or 6 are already together.
You may have to amke your window a little smaller, since you cannot cut the blocks. You can get 1/2 blocks thought. Good Luck

Yes, it is easy! But do yourself a big favor. Look in the yellow pages under glass block and visit one of those companies. DO NOT bother with the big boxes. I know from experience. I built a glass block bar last year.

The glass block companies are happy to offer advice. They really know what they are doing! Their prices are comparable to the home improvement centers for standard size blocks.

They have sizes and styles the big boxes won't carry.

Don't forget the vents. You may want some fresh air thru those windows.

Take your dimensions to them. You then have 3 options:
<LI>buy the materials and assemble yourself
<LI>let them assemble the windows - all you do is install like a regular window
<LI>let them do it all

You may be suprised at how little it costs to let them do it all, especially considering your time.

I've seen pre-assembled glass block windows (or sections thereof). Both assemblies used silicone caulking instead of glass block mortar. Other that ease of installation, is there any difference between using mortar versus silicone caulk when installing glass block? Is it better to use the pre-fab window or construct the window ourselves?
