Paint Attic Ceiling Radiant

The term radiant barrier is supposed to describe products that reflect over 90 of radiant energy and these paint products simply cannot do that.

Paint attic ceiling radiant.

Radiant barrier ceramic paint coating reflects heat provides a thermal barrier that reduces attic temperatures. 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. The results were very telling. The reality is that most radiant barrier paint products end up reducing radiant heat into the attic by about 20 40.

Radiant heat accounts for 93 of heat gain in the summer and 50 to 60 of heat loss in the winter. Hy tech ceramics and aluminum pigment provide a barrier to radiant heat reducing attic temperatures. 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. It s misleading and simply not truthful.

Which type of radiant barrier is best. This product is a radiant barrier paint that helps reduce the heat in the attic. These figures are for the average reduction in heat flow through the insulation path. A control study was published in 2013 showing the radiant barrier effectiveness of paint foil backed sheathing and foil that was stapled onto the rafters.

Radiant barrier radiant barrier spray radiant barrier paint. How to paint your attic using hy tech barrier coat the radiant heat reflecting coating for attics and walls. 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.

And remember there is technically no such thing as radiant barrier paint. 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. See insulation diagram above. 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.
