What Are Glass Block Windows – Worth it

Glass block windows are common in basements and bathrooms. They’re secure, energy efficient, and offer privacy without window treatments.

Glass block windows, popular in the 1980s, are now experiencing a resurgence in popularity. They come in a variety of designs, patterns, thicknesses, and privacy levels.

If you’re unsure about whether these windows are right for you, here’s what you need to consider.

So, what exactly is a glass block window? It’s a large panel consisting of smaller thick glass blocks. The typical glass width ranges from 2″ to 4″.

While the level of privacy offered by these windows may vary between manufacturers, you’ll generally find three main types:

– Wavy: This pattern is commonly seen on basement windows and provides maximum privacy.

– Clear: If you want a window that allows a clear view through, this design is for you. However, it doesn’t offer privacy.

– Ice: Windows with an ice treatment create a frosty appearance.

In conclusion, glass block windows are making a comeback and offer a range of options to suit different needs.

Aside from privacy levels, modern glass block windows come in various designs. Glass block windows can be fully fixed or have a small section for ventilation. Unlike standard windows, they do not open, which makes them more energy-efficient and secure. Smaller glass block windows are available at affordable prices, starting at $100 for a 31″ x 23.25″ window.

Larger varieties can cost up to $1,000. The installation cost of glass block windows is slightly higher than that of standard vinyl windows, starting at $60 but can go up to several hundred dollars, depending on size and complexity.

Glass block windows are cheaper than most other types, offer privacy, and are secure and energy efficient. However, they can also be heavy, so you must ensure your wall can support the weight before installation.

Glass block windows provide little ventilation and may not be suitable for those who enjoy a breeze. Additionally, the seal around the glass block can deteriorate over time, leading to air or moisture leakage.

When choosing a window for your basement, it can be challenging to find something secure, energy-efficient, and affordable. However, both glass block and vinyl options are viable.

Both glass block and vinyl windows are available at similar price points. While vinyl windows offer the advantage of ventilation through opening, glass block windows provide a tighter seal, privacy, and enhanced security.

Aesthetics should also be considered. Glass block windows, currently experiencing a resurgence, may not remain popular for long. On the other hand, a simple vinyl sliding window is always a timeless choice.

When browsing a home improvement website, you will encounter windows labeled as either glass block or acrylic block.

What distinguishes them?

Acrylic blocks are constructed from acrylic resin, comprising 2-3 acrylic panes. They are 70% lighter than glass and purportedly 33% more energy efficient.

Currently, acrylic glass windows are commonly used in bathrooms, as room dividers, shower surrounds, and exterior window options.

Additionally, what are the top alternatives to glass block windows?

Not sure if glass block is right for you? Or do you want to replace your glass block windows with something new?

Here are the best alternatives to glass block windows:

Awning Window:

If you want to replace a glass block basement or bathroom window, you can find awning windows in similar sizes. They have a hinge at the top and a crank at the bottom to open them outward.

Awning windows are secure and airtight when closed.

Horizontal Sliding Window:

Another option is the horizontal sliding window. These windows are operable and can fit into tight spaces. You can choose from aluminum, vinyl, fiberglass, or wood-framed sliding windows.

Fixed Vinyl Window.

If you love having a window that doesn’t open, consider replacing it with a fixed vinyl window. Fixed vinyl windows offer the security and energy efficiency of glass block, without the ability to open.

If you prefer the look of glass block but want something lighter, acrylic block windows are a great option. They provide the same benefits as glass block windows with added energy efficiency.

Glass block windows can be purchased at major home improvement stores like Lowes, Home Depot, and Menards, as well as local specialty stores. However, it’s important to note that top window manufacturers such as Pella and Andersen do not carry glass block windows.

As for the lifespan of glass block windows, they are known to be durable and can last a long time.

Glass block windows typically last 15-30 years, depending on the manufacturer. However, the seal around the window may deteriorate and require maintenance before that time.
