St. Louis Glass Block Windows 

Enhance the Beauty & Security of Your Home 

Glass block windows are a beautiful addition to any home. By combining the beauty of glass with the strength of masonry, glass blocks are the most secure window option on the market. Due to their thick, semi-transparent construction, glass blocks obscure visibility, making them a good option for spaces in your home where you’d like more privacy. Glass block windows are also an excellent choice for more vulnerable spaces in your home, including the basement, garage, and bathrooms.

With more than 30 years of industry experience, the window installation and replacement experts at Building Envelope Experts can assist you in replacing your existing glass block windows or upgrading your home with new glass block window installation in St. Louis and the surrounding areas. We utilize a holistic approach that accounts for a variety of home comfort and efficiency concerns.

Where Should Glass Block Windows Be Installed? 

Glass block windows can be installed anywhere in your home for a beautiful, secure finish. Some areas of the home may benefit more from these types of windows.

These areas include: 

  • Basements: The basement is the easiest access point into the home and should, therefore, be equipped with windows strong enough to deter intruders. Due to both their density and sturdy construction, glass block windows are near impossible to break through. The thickness of the glass also offers obstructed visibility, ensuring that no potential intruder can see any valuables housed in your basement.
  • Garages: Similar to the basement, the garage is an easy-access point for intruders. The garage also typically houses valuable possessions and pieces of equipment, such as cars, lawn mowers, power tools, and more. Protect your garage and the items it encloses with glass block windows from Building Envelope Experts.
  • Bathrooms: Bathrooms require the most privacy of any room in your home. As a result, windows in bathrooms are typically small or avoided altogether, leading to a lack of natural light. Glass block windows are an excellent choice for bathrooms, as they provide both natural light and privacy. Elevate your bathroom with beautiful glass block windows from Building Envelope Experts.

Why Glass Block Windows?

Glass block windows offer several advantages over other window options. At Building Envelope Experts, we can help you determine whether glass block windows are the right solution for your specific needs. 

Some of the main benefits of glass block windows include:

  • Better Security: Unlike standard residential windows, glass blocks are nearly impossible to break through due to their density and sturdy construction. For this reason, they are ideal for use in basements and other easy-access points throughout the home.
  • Enhanced Privacy: The thick, semi-transparent fabrication of glass block windows provides increased privacy due to the inability to make out objects or scenes on either side of the glass.
  • Improved Energy-Efficiency: Glass block windows can be utilized for air intake and venting for high-efficiency furnaces and air conditioning systems. By fabricating custom vented openings in glass block windows, we can vent your HVAC system directly through your new glass blocks, adding to the overall efficiency of your home comfort system.

Our licensed technicians have extensive experience installing and replacing glass block windows in homes throughout St. Louis and beyond. We are also Building Performance certified, meaning we are specially trained on providing whole-home solutions designed to improve the overall performance of various residential comfort systems.

Glass Block Window FAQ

Are glass blocks cheaper than windows? 

While a variety of factors affect the overall cost of glass block installation, this is generally a more affordable option than standard thermal-replacement windows. Over time, glass block windows can also offer additional cost savings in the form of reduced energy bills, thanks to improved energy-efficiency throughout your home. However, note that the amount of glass blocks being installed, the frame material, and various other installation-related costs can affect how much your glass block window installation will cost. We recommend that you reach out to our team at Building Envelope Experts to request a free, onsite estimate.  

Are glass blocks better than windows? 

This depends on your definition of “better.” Glass blocks offer several advantages compared to traditional windows, including increased durability, insulation, privacy, and security. However, because they are semi-transparent, you cannot see through glass blocks like a regular window. For this reason, some people may opt for traditional thermal-replacement windows or only install glass block windows in certain areas of the home, such as the bathroom, garage, or basement. 

Are glass blocks out of style? 

Like all home design trends, glass block windows come and go in terms of style. That being said, demand for glass block windows has surged lately, thanks in large part to their unmatched durability. Modern glass block windows are made from the highest quality materials and can be customized to suit your specific design tastes. At Building Envelope Experts, we believe glass blocks to be a timelessly beautiful addition to any home, all while improving energy-efficiency, reducing your energy costs, and enhancing your family’s safety. 

Are glass block windows energy-efficient? 

Because they are so thick, glass blocks offer incredible insulation. At Building Envelope Experts, we are committed to top-quality glass block window installation to ensure optimal energy-efficiency. This includes properly placing the mortar to prevent drying, cracking, or chipping, which can lead to leaks.
