Glass Block Windows: Pros and Cons

Glass block windows, first used during the 1900s, are making a comeback. This design element is favored for its thickness and unique, attractive look that no other type of window has. Popularly used in bathrooms and foundation walls, they can now be seen in living rooms and bedrooms.

If you’re considering installing glass block windows on your property, it's a good idea to inform yourself first of what they have (and don’t have) in store for you. Read on to learn about the pros and cons of glass block windows.

Pros

Aside from their visual appeal, glass block windows have several other benefits. Here are some of them:

Energy-Efficient

More than simply allowing natural light into your space, glass block windows provide great thermal insulation values similar to double-pane windows. But since they are impenetrable and securely held in place by mortar, they prevent air from getting in, blocking drafts and dust and reducing noise from outdoors.

Privacy

Given their unique pattern, glass block windows ensure your privacy. For example, if you use them in your bathroom, you wouldn’t have to worry about being seen from the outside. You also get the most out of natural light without compromising privacy.

Very Low-Maintenance

Glass block windows require little to no maintenance. Pressure washing is enough to keep them in optimal condition. You also don’t need to worry about dirt buildup as these windows have no edges where dust or debris can accumulate.

Green Building Credits

Having glass block windows can qualify your home as LEED- (Leadership in Energy and Environmental Design) and Energy Star-certified. These programs affirm the energy efficiency and environmental sustainability of properties. This can attract buyers if you ever plan to put your home for sale.

Cons

Like most architectural elements, glass block windows also have their share of disadvantages. Here are some examples:

No Natural Ventilation
​
Because glass block windows are stationary and sealed in place, they don’t allow air to come in. You don’t have the option of opening them to let fumes out or fresh air in. You’ll have to rely on an air conditioner or other similar systems for indoor ventilation.

Significantly Heavy

Glass block windows are much heavier than other glass or window options. They need an especially sturdy foundation, which can limit the areas where they can be used in your property. They can also be tough to construct, and their installation may require increased professional support.
