Insulative paints, or insulating paints are a specially designed type of paint in which can be used to coat a surface (e.g a wall) to reduce heat transfer as well as increase the thermal insulating property (R-value in order to aid cooling and heating efforts for example.Insulative paints use a technology where a broad spectrum thermally reflective coating is applied to a specific type of micro-spheres to block heat radiation in a larger range of thermal energy (heat) to dissipate heat rapidly. This type of coated thermally reflective material (coated micro-sphere) reduces heat transfer through the coating with 90% of solar infrared radiation and 85% of ultraviolet radiation being radiated back from the coated surface
An “insulative” or “insulating” paint works bi-directionally (reflects heat coming from either direction toward the painted surface. An example of this would be an exterior wall of a building to which an “insulative” or “insulating” paint has been applied. Solar induced heat (direct sunlight) is reflected from the surface as well as heat (winter months) that is migrating through the wall outward toward the colder outside air. A “thermal Image” or infra-red photograph will clearly show the reduction of winter time heat loss from a home through areas that have been painted with a true “insulative” or “insulating” paint.
The ability to reflect or block heat from all sources such as fireplaces, heaters, and radiators inside a building as well as sunlight is the value of a true “insulative” or “insulating” paint. These products reduce the work (heat loading) that “resistance insulation” such a fiberglass, foam, and rock wool have to do. These are typical insulation materials used in walls as well as ceilings of buildings.
So far no manufacturer has provided any independent test results to substantiate any claims of improved performance over standard paint technology. All independent tests have shown that the proprietary formulas offer no advantages at all over plain old acrylic paint. In spite of impressive “web presence” several of these companies appear to be “ghost ships” operating in the cloak of obscurity offered by internet sales and unable to provide any local representation or product stocks.
