Acrylic blocks offer a great alternative to traditional glass block.
Are Glass Block Windows Attractive? While beauty is in the eye of the beholder, many current design experts, home decorators and architects agree that the look of glass block is outdated, unattractive and unnecessary.
Polycarbonate is a versatile material that's temperature resistant, impact resistant, crack and scratch resistant – and virtually unbreakable.
The most obvious difference is that glass block design shapes are limited to right angles. Acrylic blocks have greater design flexibility because we can achieve architectural shapes such as arches, ovals, octagons, and triangles in the factory.”
Another significant downside of glass block windows is their lack of insulation. They are not as energy-efficient as modern double-pane windows, which means they may allow heat transfer, causing your bathroom to become chilly during the winter and excessively hot during the summer.
Disadvantages of Glass Block
No ventilation: Glass block windows can have small vents built into them, but you can't open the entire window, limiting the amount of ventilation in a room. Cost: There is no substantial cost benefit to installing glass block vs. regular windows as they can be similar in price.
Glass block windows last about 15 to 30 years, which is the same amount of time, if not slightly less, than standard windows. Standard windows last 20 to 50 years. You can extend the life of your glass block windows by resealing them every few years.
The short answer is no. However, glass block walls, while not load-bearing, are self-supporting.
The first glass block will need a flat spacer applied to its vertical edge that meets the framed wall. Apply silicone to flat spacer and press on to block. Apply two large globules of silicone roughly 1” diameter to flat spacer on exposed (framed wall) side .
When you need a glass substitute, you're probably looking at either polycarbonate or acrylic. Both polymers offer the transparency of glass but are much more resistant to impact and scratching, and they're more cost-effective and lightweight.
Greenhouse plastics: Polyethylene (PE)
In this case, polyethylene is the most widely used type in greenhouses around the world because of its competitive price and excellent mechanical properties. In addition, it is very easy to incorporate additives to improve its characteristics.
Plastic materials such as acrylic and polycarbonate are great alternatives. They are lighter and performance isn't affected as the materials are clear and transparent. Also, the strength of these products are incredible. Both are shatterproof so no need to replace the panels ever again.
The most apparent difference between a glass brick and a glass block is that a glass block has a hollow core and a glass brick does not. A glass brick is a solid piece of glass. It is made by pouring a molten mixture of soda ash, silica particles and other components into a single mould.
Architects and designers are deploying the once-dated building material in fresh, modern ways. Along with 1980s neon manicures and vintage '90s blazers, glass blocks are making a comeback thanks in part to a new fan base on social media.
Clients on every budget can afford walkable glass in the form of a modular glass block and metal system. These walkable glass floors are exceptionally versatile and suited for bridges, stair treads, hallways, balconies, sidewalks, and other indoor and outdoor walkable glass floor applications.
Acrylic blocks offer a great alternative to traditional glass block. It looks just like the real thing, but weighs and costs less. Acrylic is durable, energy efficient, and easy to install. You can use them for partitions, shower walls, or clock windows.
traditional mortar, making it easier and more cost effective to package and ship glass block. Additionally, silicone provides great insulation. Because it can be easily applied with a caulking gun, silicone is typically easier and cleaner for homeowners to install.
What is the R-value of glass block? The R-value for Premiere Series glass block is 2.08, which is more than twice the value for flat 1/8" sheet glass windows or roughly equivalent to a double pane thermal window. The Thinline Series R-values are slightly lower at 2.00.
Glass blocks are experiencing a resurgence in architectural and interior design circles. The true origin of glass blocks as building components can be traced back to the late 19th century.
On average, expect to pay $710 to install glass block windows. This can be a complicated project, so you should hire a professional installer near you to do the job right.

Unlike traditional window panes that are easy to shatter, glass blocks are thicker and more robust, making it extremely difficult for intruders to break in. This added layer of protection can give you peace of mind, especially if your basement houses valuables or serves as a family gathering area.
Insulation
Energy efficient glass blocks can improve the energy efficiency in your home. Many of these blocks are certified high thermal insulation capacity and have a double chamber inside the block. These glass blocks are assembled with a polystyrene frame that acts as a thermal break to reduce heat conductivity.
