What Are the Benefits of Block Windows?

Block windows are thick, translucent, or patterned blocks of thick glass in a window frame. They’re usually about 2 to 4 inches thick and consist of multiple blocks mortared together (sort of like a brick wall). Although a more expensive option, they’re strong and secure, with additional benefits including:

  • Better energy efficiency
  • Waterproof
  • Privacy options
  • Unique design
  • Allows natural light

Types of Block Windows

Although block windows are characterized by their block-like appearance, that doesn’t mean they’re limited design-wise. Block windows come in a variety of different glass types that can fit any space.

  • Wavy Block Windows

    Wavy block windows are the most popular type, and are typically used as basement windows. They have a wavy, distorted pattern that allows light to pass through while still offering privacy.

  • Clear Block Windows

    Clear block windows are completely clear blocks of glass. Although they do not offer any privacy, they allow the maximum amount of light to pass through. They’re great in kitchens or entryways.

  • Ice Block Windows

    As their name suggests, ice block windows (also known as ice-pattern) have a crackled texture that looks like a sheet of ice. They’re popular in bathrooms or any other space that needs both privacy and light.

  • Diamond Glass Block Windows

    Unlike wavy and ice block windows, which are textured to the touch, diamond glass windows are smooth. That’s because their diamond texture is embedded inside the block, refracting and dispersing light.

Frequently Asked Block Window Questions

  • Block windows have some size limitations, as the bigger they are, the more supports and joints are needed to reinforce their weight. They typically max out around 12 by 15 feet.

  • Standard block windows typically can’t be opened; however, if you’re worried about ventilation, block windows can be installed with venting units. These are small panels fitted inside the block window that can be opened or closed to allow air to flow through.

  • Although block windows make a great addition to any room, they’re best-suited for areas where you want privacy, security, and good insulation. As a result, they’re frequently found in basements, bathrooms, and garages.

  • Since block windows can’t open or close, they’re one of the more energy-efficient window options. Sealed shut with mortar and silicon, they have fewer openings for cold or warm air to come in or escape. This helps keep heating and cooling costs to a minimum.
