Thermal insulation is also achieved by the installation of false ceilings. The air-filled space between the two levels of ceiling cools the space. Many people are unaware that false ceilings aid in the better optimization of air conditioning. They save space in ceilings while improving air conditioning effectiveness. False ceilings are also useful if you want to change the look of an office. False ceilings are usually made out of fiberglass and can be painted any color you like. They come in shapes other than squares, such as circles, triangles, and stars. These shapes allow for more design flexibility in decorating offices. Fiberglass ceilings are durable and easy to maintain. If anything gets spilled on it, just sweep it up. There is no need for any additional cleaning products. They are also very safe. If there's a leak under the roof it will usually stop at the ceiling first because that's where the pressure is lowest. Thus, false ceilings protect people from water damage. Finally, they are affordable. A typical ceiling replacement job costs about $10,000. Fiberglass ceilings can last 20 years or more with proper maintenance. That means you won't have to replace them for several years after you initially install them.
