In the summer, you get the greatest reduction in air-conditioning costs and improvement in comfort by painting the exterior of your house with ceramic-filled paint. This allows you to set your thermostat lower and save more energy. A cold wall surface is a primary cause of a chilly feeling when you sit near an outside wall. Therefore in the winter, you lose less heat by radiation to outside walls and more of the heat is reflected back to you.

You can hold a cigarette lighter under a metal strip coated with ceramic-filled paint and not burn your finger on top of the strip.Ĭeramic-filled paint has a lower emissivity than ordinary interior wall paint. They are very reflective to heat radiation (not reflective in appearance) and they dissipate heat very rapidly. This is the same type of ceramic material that is used on the heat shield tiles on the NASA space shuttles.Ĭeramic materials possess unique heat-resistant and insulation properties. When applied, ceramic-filled paint looks like ordinary wall or house paint.Ceramic-filled paint uses a special durable liquid paint base with very fine ceramic particles (often borosilicate) mixed in it.

Although ordinary house paint has very little effect on energy savings, this ceramic-filled paint has unique energy-saving and sound-blocking properties. How does this type of paint work? G.S.Ī - You are referring to the new 'ceramic-filled' types of interior and exterior house paint. I have heard about some special 'space-age' exterior house and interior wall paint that can lower my heating and air-conditioning bills and help soundproof my house.
