Frequently Asked Questions (FAQ's) About Glass Block Basement & Bathroom Windows 

1) How do I measure my windows?

For glass block basement windows in a concrete block or poured cement foundation measure from each side of the foundation (assuming the frame will be removed) and from the top of the sill to the header above the existing window. For a glass block  bathroom window you'll estimate the size once the window frame is removed (which is usually easier to get from the outside of the home vs. the inside (where trim may be covering the full size of the opening). Since a glass block shower window is trickier to measure you may want to talk to a representative and/or send pictures to assist you with this process. Note - if you don't want to worry about measurements, ask us about how our team can provide a turnkey glass block window installation service for you in Cleveland or Columbus Ohio. Nationwide we can wholesale the prefabricated windows to you and assist you or your contractor through the process. 

2) Should I purchase premade windows with mortar, silicone or your Innovate Protect All process?

Mortar, silicone and the Protect All Glass Block Windows each have their own advantages and disadvantages, but purchasing premade windows, rather than installing windows block by block, creates a better finished product and saves money. See the advantages of each system below. 

  • Mortar Advantages - Harder to break through, traditional masonry look, more variation in joint size.
  • Silicone Advantages - All-glass look, windows come out smaller in size, easy to clean.
  • Innovate Protect All Advantages - Hardest system of all to break through, uses a consistent 1/8" silicone joint for maximum protection vs. water & air infiltration, 22% more energy efficient, protects vs. any cracking of mortar joints between the blocks

Yes - you can choose from a broad selection of designer glass blocks or the clear glass block windows shown above. You can even personalize your project with a one-of-a-kind etched and engraved blocks.

4) Are your windows made with frames or without frames?

Most glass block basement windows are made without frames and then mortared into concrete block or poured wall foundations. In remodeling a glass block bathroom window is premade without frames. In new construction projects, it's best for your shower window to use a vinyl frame glass block windows.

5) How do you finish glass block bathroom windows on the inside and outside?

The answer depends on the surrounding materials on the inside and outside. For an installed project an Innovate Estimator will look at your framing structure and/or foundation and make the best recommendation for how to finish things off. If you're outside of our installed markets of Cleveland and Columbus Ohio send us digital images and we'll guide you through the best window (framed or frameless) for your job. Below are our general recommendations.

  • Inside - If the existing tile that returns to the window being replaced is in good condition, butt the glass block up to the tile and mortar it into place. If the existing tile is not in good shape, install a vinyl trim kit (see the picture below), new tile, or a solid-surface material like cultured marble or granite to finish the window replacement.
  • Outside - For brick and block window openings, mortar in the glass block basement or bathroom window into place. For stucco or vinyl or wood siding, seal the window to aluminum- or PVC-coated vinyl coil stock wrapped around wood trim (see the picture below).
