Types of Glass Block

There are different types of glass block that require different attention. Large panels of traditional glass block are heavy and difficult to secure, requiring additional reinforcement that should be done by professional installers. However, there is a new type that is made for the average homeowner to install, and it is made of acrylic.

It is lightweight, and it is already pre-assembled in one large panel. You need to look into the variety of options available for installation, like a mortarless, frame system, the frameless, clip system or the pre-built system. Each will require a different level of ability, but if you stick to the manufacturer instructions, it can be fun and creative. Best of all, you don't need to know how to frame a window.

You also need to be aware of the different stylistic options you have, ranging from clear glass to colored glass to customized shapes to engraved designs. When you know the style you want, you need to match it to the right format to prepare to install.

How to Install

The pre-built type is the easiest for the average homeowner, so here are some tips to handle that type.

1. Spread caulk around the entire edge of the window opening.

2. Place the panel onto the caulk and hold it centered.

3. Hammer nails around the panel to secure it.

4. Attach trim around it.

If you want the challenge and the creativity of using mortar to put in the individual glass blocks yourself, here are some guidelines.

1. Your panel will have anchors attached to it. Bend them and nail them to the frame.

2. Mix your mortar by following the manufacturer's guide.

3. Spread a layer of mortar around the first glass block. Squeeze it into place beside plastic spacer, and then repeat for the next glass block, attaching it to the first. Continue for the entire row.

4. After three rows, put a layer of mortar on top and attach a wire stabilizer to add support.

5. Above the stabilizer, you can continue attaching glass blocks to complete the window or in some cases create glass block walls. It will need to dry for 1-2 days.

Glass block installation can be done the long way, or the simple one; it all depends on the amount of personal touch you want to add or the time you have to spare. Whichever method though, you will end up with an attractive and efficient result. It may not replace all your windows but at least it's different from regular wood replacement windows.
