Glass Block questions, answered by experts

If an individual block breaks, you can remove and replace it. This is a job for which you should contact a professional because the project is usually complex, involving you having to break the block further.

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.

Glass blocks are much thicker than glass panes in traditional windows and serve as better insulators. The overall glass block window is sealed against drafts that allow warm or cool air to escape, saving on energy costs. Since this type of window is sealed airtight into your home, you don’t have to worry about air leaks and drafts as often as traditional windows that open and close. When installing glass block windows, look for options that are Energy Star rated, proving their energy efficiency.
