Abrahamson Services provides a wide range of services to the 4 county Milwaukee area. Anything from windows, doors, roofs, gutters/toppers/cleaning, to roof raking, ice removal and interior work

"Ken was fantastic from start to finish. I hired him to remove an old basketball hoop, pour new cement, and install a new one. The job turned out to be much tougher than expected—the old cement was nearly impossible to break up and the clay ground was hard to dig deeper for the required dept —but Ken handled it like a pro, using a jackhammer and digging through hard clay soil without complaint. Despite the extra work and materials needed, he stuck to his original price even when I asked to pay him more, which speaks volumes about his integrity. He returned a few days later to assemble the hoop, and the final result was perfect—every measurement was spot-on. Ken went above and beyond, and I wouldn’t hesitate to hire him again. Highly recommended!"

Glass Block Windows questions, answered by experts

Most installations take 1-3 days, depending on the number of blocks and customization requirements.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Options include tempered, laminated, and tinted glass for various needs.

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.

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.
