Glass Block Windows Are Practical Alternatives to Conventional Glass

Glass block windows are practical alternatives to conventional glass. Favored for their classic elegance, glass blocks provide filtered lighting and security due to the double-layer construction. Made of acrylic, glass or other transparent materials, glass blocks add aesthetic appeal and create dramatic design lighting. When replacing traditional windows, be aware that glass block windows do have some disadvantages. Privacy Glass blocks allow diffused light into the room. They block clear views inside and outside while allowing dim images of figures and movement through the glass. Because these windows do offer opaque vision, they can lull you into a false sense of security. At night, an outside person sees more easily into a lighted room. At dusk or night, treat these windows as if they are clear glass. For reasons of privacy, avoid placing the windows in bathrooms, children's rooms or bedrooms unless you also use window coverings that protect inhabitants from bystanders or casual watchers. Although the glass blocks do not allow a clear view, they may let more images through to prying eyes than you realize. Light Diffused light is tranquil light for conversations and meals but may provide insufficient light for reading or computer work. Install supplemental lighting at work or reading areas. The glass block windows let light through their textured surfaces. This type of light can be distracting for focused vision work or when reflecting on television or computer screens. Install window coverings such as curtains or window blinds. Available at department and home improvement stores, these coverings are installed over glass block windows just like over conventional windows. In a few minutes you can install lightweight curtain rods to hold drawback curtains covering the windows. Pull back and tie the curtains when more light is desired. Moisture Glass blocks condense moisture in the air. When used in bathrooms or kitchen areas, steam or humid air collects in the windows. As the moisture condenses, it rolls down the glass blocks and collects on the molding or frame. Mold spores thrive in the warm indoor air and the pooled water. Inspect the windows frequently for signs of black stains indicating mold, and clean the mold up promptly. If possible, ensure good ventilation around the windows so that condensation is minimal. Some glass blocks lose their seal and, in rainy weather, collect water inside the blocks. This water leaks out and causes window frame damage such as peeling paint and rotting wood. When you see water collecting inside the blocks, repair them or call a window specialist to fix the leak. Considerations Glass blocks provide security by keeping intruders at bay, but they also block egress or escape in an emergency. The windows do not open and are difficult to break. Ensure every room has another window that opens and closes or a door that leads quickly to an exit. In some areas, glass block windows violate historical or heritage guidelines and are not permitted for window use. Source: eHow
