Paint Attic Ceiling Radiant

Radiant barrier ceramic paint coating reflects heat provides a thermal barrier that reduces attic temperatures.

Paint attic ceiling radiant.

Lo mit attic heat barrier is a coating specially formulated to reduce summer radiant heat gain from the roof into the attic. And remember there is technically no such thing as radiant barrier paint. The term radiant barrier is supposed to describe products that reflect over 90 of radiant energy and these paint products simply cannot do that. Radiant barrier is a low emissivity reflective coating that is sprayed on your attic ceiling.

Lower attic temperatures mean less wear and tear on your cooling system and increased comfort for you. Don t believe anyone that says that radiant barrier paint is as good or as effective as attic insulation. Hy tech ceramics and aluminum pigment provide a barrier to radiant heat reducing attic temperatures. This low e radiant heat reflecting coating will lower your attic temperatures reducing the load on your air conditioning equipment.

Solar attic fans offer about the same savings. Radiant barrier paint performed the worse providing a heat decrease in the conditioned space of around 19. Lo mit is a silver colored non thickness dependent low emissivity radiant barrier paint interior radiation control coating system irccs which may be used in almost any application where infrared heat reflectivity or diffuse light reflectivity is required. The results were very telling.

These figures are for the average reduction in heat flow through the insulation path. Radiant barrier radiant barrier spray radiant barrier paint. 129 walters avenue ewing nj 08638. The reality is that most radiant barrier paint products end up reducing radiant heat into the attic by about 20 40.

The tests to date have shown that in attics with r 19 insulation radiant barriers can reduce summer ceiling heat gains by about 16 to 42 percent compared to an attic with the same insulation level and no radiant barrier. See insulation diagram above. Radiant heat accounts for 93 of heat gain in the summer and 50 to 60 of heat loss in the winter. The term radiant barrier has been misconstrued by the people who install the paint and it s essentially like trying to call a hamburger a prime steak.

Which type of radiant barrier is best. It s misleading and simply not truthful. Just like you learned in physics the silver coating repels radiant heat while the most efficient choice would be to re insulate the attic with spray foam insulation the combination of sealants and radiant barrier paint provide a cheaper alternative.
