While glass block needs no additional tooling to be effective, a skilled installer and some supplemental structural work may be required in some situations. New on the market are acrylic-block windows. For instance, on wood-frame windows, you can choose an oak, maple, cherry or mahogany interior finish to pick up on existing cabinetry or trim. Vinyl and wood-clad windows come in a wide array of colors, with custom shades available. Details like keystones and corner blocks can further personalize your windows.
Purists prefer authentic divided lights to grilles.
But it's tough to clean their many small panes. That's why simulated divided lights have become popular. They feature a removable, often wood, grille on the inside, a metal grille on the outside and usually two full-frame glass panels separated by spacing bars that mimic the muntins. Custom grilles are also available. Pozzi produces them in diamond-pattern, radius and other designs.
