"Mr. Hernandez was terrific. I cannot say enough good things. I had five projects for him and he did each one perfectly. He even *made* a piece for my door on the spot out of wood that was in my garage! He was so tidy that there was nothing to clean up. He installed cabinets! He fixed two doors! He installed weatherproofing strips. He was very good about keeping in touch and letting me know when he would come. And he's nice, too!"

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 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.
