Are you considering a glass block window installation project but are concerned about the weight of the blocks? Worry no more, there is a solution for you. With the introduction of the 2″ thick series of block fabricated vinyl frames, installation of this window has been simplified to install a lighter and safer window assembly. In this article, you will learn 5 tips on where and how to use a vinyl framed block window.

Tip 1 – Identify where you want to use the window – Glass block windows have many uses beyond what most people realize. Here are some common (and more unique) uses to consider:

• bath and shower– With this type of window, you can ditch expensive blinds and window treatments in the bathroom while still getting maximum light transmission. Use this window in the shower to provide a low-maintenance light source in this wet area.
• The essential – This cost-effective use is popular for providing maximum security at a cost-effective price.
• Den– place these windows under cabinets to let in natural light and maintain privacy.
• Wardrobes– Do you have trouble seeing well in your closet with only a small lamp above it? One solution is to install a fixed block transom window near the top of the closet walls. This will even help color blind people distinguish between blue and black socks.
• Garage – If you like to use your garage for projects, the natural lighting is a great benefit and the block window also provides high security for any valuable items you may be storing.
• Kitchen – A block window between kitchen counters and cabinets can let in light and provide a natural backsplash that’s easy to clean.

Step 2 – Determine if a framed or frameless window is better: Lighter 2″ thick glass block windows are only available in a vinyl framed system. Although the lighter window is easier to work with, the vinyl framed system is not the best solution for all projects Here’s where to use framed and frameless systems:

• vinyl framed windows– use on wood framing (rough openings) where the opening size will work with the dimensions of 2″ thick blocks (note: 2″ thick blocks come in a size of 8″ x 8″ x 2″, so rough openings need to work in 8″ increments). These windows (which are available with easy-to-install nailed fins) are often used in new construction, room additions, or in framed and stucco openings on upper floors where window openings can be adjusted to fit the window.
• frameless block windows– this window is (available in heavier 3″ and 4″ thick blocks) generally more cost effective than the framed system and is best used in masonry openings where block windows can be mortared in place. The other advantage of frameless windows is that they are available in more block sizes (4″ x 8″, 6″ x 6″, 6″ x 8″ and 8″ x 8″ are the most common) which allow these window construction panels to be designed in 2″ size increments. Most basement windows are completed with the frameless system.

Step 3 – Make Sure This Window Is Sturdy: Not all vinyl framed glass block windows are created equal. Be sure to choose a window that is built to withstand extreme weather conditions. The best manufactured windows use a vinyl stack spacing system between the blocks that provides greater impact resistance, minimizes the possibility of water infiltration, and offers greater wind load capacities.

Step 4 – Add flair with color blocks, frosted and etching. You no longer need to make your window decision based on a one-size-fits-all approach. You can select from a wide variety of etched, frosted, and colored glass blocks. On the lighter 2″ series blocks (which are manufactured by Mulia Inc.) you can choose between two privacy patterns called Wave and Iceberg. White and almond frames are also available.

Step 5: If the window does not fit, you must acquit- A block window is not the right solution for all projects. If you’re looking for full operability (but like the look and privacy of blocks), you may want to consider using an acrylic block window. This type of window is available in several opening styles, including single, slider, casement, awning, and hopper styles.

Now that you’re equipped with these 5 tips, you’re ready to start ordering your lightest weight vinyl framed glass block window.
