Are these Glass Blocks: Blue and Black? OR White and Gold?

With all this internet craze about the mysterious dress and its true colors, we have decided to add a color mystery of our own. So, as you see these pictures below, tell us what you think.

They say that there are two things in life we can be sure. There is a third. That third thing is that the winter weather will end.

The bad news is this will possibly result in flooding from the melting snow and ice. And, the flood water will find its way to the most vulnerable part of your home – the basement window. We need to be prepared – if not for this time, then for the next time.

So, how do you make the basement window as impenetrable as a brick wall and still allow light to enter the house?

A glass block basement window is a great choice to stave off the threat to your basement windows.

Let’s look at the advantages of a Mortared Glass Block Window 

  • Water Resistant because it is like a solid concrete block wall.
  • Comparable to a double pane window. Eliminates drafts.
  • No need for window treatments. Privacy is controlled by pattern selection.
  • Resists breakage and entry, thereby, reduces the risk of burglary.
  • No maintenance.
  • Very comparable to a single pane window in cost.

Installation is easier than expected. Glass Block windows are available pre-assembled. You can choose standard or custom sizes, with or without ventilation.

Installation Steps

Let’s cover the steps necessary to install a glass block window in a basement made from concrete or concrete block. (Installing in a wood-frame has some additional considerations that will not be covered here. But, call us if you have that situation.)

In general terms, installation is just setting the panel in place and packing mortar around it. But, let’s go into more detail. You will need tools that may not be a standard in your toolbox, like a masonry chisel and select trowels. But these are easily found in any hardware store and will come in handy during a future project around the house.

1) Remove the Old Window

First, you need to remove the old window. Use a crowbar to pry out the old window jamb. You may need to cut the wood sill with a handsaw or circular saw. Use a chisel or utility knife to displace whatever was holding in the old window jamb. At this point, you just need to get tough without causing structural damage. The objective is to completely get out the window sill, the side jambs, and the head jamb.

2) Set the New Window in Place

Next, you need to prepare to set the window panel. Before you set the panel in the rough opening, you need to attach a temporary block to keep the panel from falling through the opening while you mortar it in place. Screw a wood block to the underside of the sill plate, or to a joist if there is not a sill plate. The temporary block should be set far enough in that you will have the window recessed to the depth of your choice.

Now you are ready to set the panel in the rough opening. Make sure to sweep the rough opening clean before you set the panel in place.

You will need to have at least three wedges to temporarily raise up the panel when you set it in the opening. Make sure that the wedges are greater than the thickness you will need and that they are long enough that you can grab onto them when it is time for them to be removed.

3) Mortar the New Window in Place

The last step is to pack the mortar. Pack and smooth the mortar at the bottom first. Be careful to not mortar in the wedges. Wait until the mortar has hardened somewhat along the bottom before you mortar the sides. Remove the wedges. Fill in all the gaps and smooth the mortar for a finished look. Brush away all mortar crumbs. Make sure that all gaps are filled in on the inside. You may want to have the mortar flush on the inside to accommodate a window sill, whereas the outside can be sloped for strong support.

Here are some commonly asked questions that will help you get started;

Do I need special support underneath the wall?

Usually not. Unless there is a problem with the floor already standard subfloor framing is usually enough to support the block wall.

Can the walls be prefabricated?

Yes. Straight prefabricated walls make the project easier and less costly to perform. Rounded walls are generally built at the job site.

Are these walls sturdy? How are the walls attached or anchored?

Most block walls are tied into surrounding wall(s) using panel anchors or vinyl stack anchors every 3rd course (or 24″). Panel reinforcing or horizontal vinyl stack pieces provide additional stability.

How do you make radius or angled walls? How are the ends and tops finished off?

With the development of glass blocks with angles, corners, and finished ends there is usually no need to use dissimilar materials to finish the sides and tops of your project.

Are there blocks with 60 or 90 minute fire ratings, or ones that offer higher levels of security?

Yes. There are solid and 60 and 90 minute fire rated glass blocks with thicker faces providing increased resistance to bullets, noise reduction, improved protection against vandalism & graffiti, and better fire ratings.
