Radiant barrier paints are newest offering for insulating your attic. Even so there are a lot of issues that occur with this new service giving from your regional insulation company. Listed here are five causes why you should not have the paint sprayed in your attic.

1. Paints and Sprays Usually are not Radiant Barrier

In accordance to the ASTM definitions of a “radiant barrier” and the FTC definitions of “property insulation”, the paint goods on the industry qualify as neither. The most successful of these paints / sprays are named “inside radiant handle coatings” or IRCCs, but some so-named radiant barrier paint items do not even satisfy the effectiveness prerequisite to be referred to as an IRCC. So how does this have an effect on the consumer? Basically said, the paint additive or spray coating goods do not meet the very same creating requirements as radiant barrier and do not qualify for the same vitality performance credits.

“Currently, EPA does not label paints and coatings for the inside of of roof decks (or attic) in the insulation software due to the fact paints and coatings do not meet up with the Federal Trade Commission (FTC) definition of ‘home insulation.'” -Energy STAR

Due to the fact Strength Star uses the very same needs as the FTC for insulation and vitality performance, these radiant barrier paints / spray coatings are not integrated in the radiant barrier prerequisite for Power Star homes. In some circumstances, there are tax credits or energy credits accessible for radiant boundaries, like latest IRS tax credits and strength credits by means of numerous towns, municipalities, and even utility businesses, for which paints will not qualify. If you are seeking to qualify for rebates like these, or have building specifications to meet up with, you want to be utilizing a real radiant barrier foil.

two. Radiant Barrier Paint / Spray Is Much less Effective

According to a RIMA Global review, an affiliation produced of makers of radiant barrier, reflective insulation and radiant barrier paint additives / spray coatings, paint goods on the market place have a extensive selection in effectiveness and power financial savings. Some of these paints only block out only 10%-14% of the radiant warmth, and some block up to 64%-eighty five% of the radiant warmth. All true radiant boundaries start off off at a least of 90%. Even the most high-priced paints with larger efficiency, might protect a smaller sized area, more lowering the efficiency. The paint is generally sprayed directly to the underside of the roof decking, leaving the roof rafters uncovered. There is absolutely nothing to stop these wood rafters from emitting the radiant warmth right into the attic. Assuming the rafters are 1.5″ broad and are spaced 24″ on center, then even the best, most costly insulation paints / sprays only block fifty nine%-seventy eight%.

In addition, paints are not often sprayed regularly or evenly throughout the roof decking. It is straightforward to see regions that have a thinner coating since the wood can often be noticed through. There have even been circumstances where installers understand at the final minute that they didn’t deliver sufficient paint for the whole roof, and do a thinner coat or dilute the radiant barrier paint with h2o to stretch it further. Given that foil insulation is mounted throughout the base of the roof rafters, and is created with a sheet of pure aluminum it will often block ninety% of the warmth or more.

three. Your Radiant Barrier Paint Could Not Last

When soiled, older wooden surface area (like a roof deck) is painted, almost any paint manufacturer or specialist contractor know that the area must be cleaned, sanded, primed and coated with multiple coats of paint. These actions are Painting one hundred and one to guarantee that the paint adheres to the area and isn’t going to peel or fade. Nevertheless these basics are fully overlooked by most paint / spray installers.

If the paint coating is sprayed to the roof decking without having cleaning off the filth and particles, and sanding down the surface area, portray in excess of filth and debris can consequence in poor adhesion and might guide to an uneven coating. Avspärrning is the main cause that paints crack, chip, peel and fade right after just a couple of several years time. Applying a primer over the cleanse, easy surface area is crucial simply because it not only boosts the durability of the paint, but offers a smoother surface to boost the reflection and all round functionality of the paint. Lastly, when you need a constant, even masking in excess of wooden, then several coats of paint are usually required.

4. Radiant Barrier Paint Might Incorporate Dangerous or Poisonous Chemical compounds

House owners who are not chemically sensitive but are still worried about a harmful or harmful item getting sprayed right in excess of their heads, proper in close proximity to their ventilation program, need to appear intently at the product’s MSDS sheet. A lot of of these paints have chemical compounds that can show hazardous when in get in touch with with the pores and skin, eyes, nose and throat.

Thanks to some of the dangerous chemicals contained in radiant barrier paint goods, producers advise that the installer dress in personalized security like an impervious protecting match, a pair of ANSI accredited security eyeglasses, and a NIOSH/MSHA accepted respirator. In fact, RIMA-International has issued a security assertion expressing that these goods could “contain hazardous chemical compounds or emit fumes, which can enter the physique via inhalation, skin absorption, or injection into the eyes, nose or throat.” Prior to use, seek advice from the manufacturer’s MSDS sheet.
