Radiant Barrier Coatings help to maintain a comfortable, energy efficient climate for your home's interior.
Radiant barriers were first developed by NASA to help protect the computers and sophisticated electronics aboard space going instruments and spacecrafts. The radiant barriers would act as a shield reflecting the harmful radiation from the sun off of the delicate electronics sitting inside. When the spacecraft flew into the cold shadows of space, the radiant barrier would actually keep the heat inside protecting it from the cold. This thin layer is the spacecrafts' vital protection, without the radiant barrier nothing would survive.

Radiant barriers used in the building industry.
Back on Earth, the radiant barrier was put to use in the building industry. They have been in use for quite some time.
One problem builders faced with radiant barriers was the ability to fit it to the building's skeletal structure. The framing members make installing the radiant barrier's sheeting film near impossible in some buildings. To be truly effective, the building must have a continuous barrier in place.
Radiant barrier coatings developed by the coatings industry.
Paint manufactures saw an opportunity to produce a product that could be sprayed into tight areas, and cover building materials that would have been impossible to cover with a sheeting material.
They designed and tested radiant barrier coatings to perform the same as their solid film counterparts do. What they came up with is a coating that can be applied to the underside of a roof deck/framing members and building material. It creates an unobstructed, complete radiant barrier for your building's protection.
The advantages of having a radiant barrier installed in your home or business is two fold. The first is the benifit a radiant barrier coating offers the radiant heat to stay inside the building's envelope during winter. This will allow you to save money off your winter heating bill. It also allows you to remain comfortable inside during the coldest parts of winter. You CAN feel the climate change in your building once you have a radiant barrier installed.
Radiant barrier coating benifits during summer.
During the summer, you will actually save money due to the suns radiation being "bounced" off the radiant barrier. This, with the help of proper amounts of unobstructed ventilation, will reduce the heat in your attic during the summer. By not overheating the attic, the adjoining living areas are easier to cool, so it puts less strain on your air conditioner, and saves on cooling bills throughout the hottest times of the summer. It also helps stabilize the climate inside your home, so you are more comfortable.
