Does attic radiant barrier work?
Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate.
Does my attic need radiant barrier?
Radiant heat moves through the surface of your roof deck to heat up your attic, entering your home and spiking cooling costs. If your home receives direct sunlight throughout the day, especially if you don’t have any trees shading your roof deck, you should consider radiant barrier installation for cost reductions.
Does radiant barrier cause mold?
Radiant Barrier Moisture Problems In colder weather, radiant barriers can sometimes develop condensation. In addition, unchecked moisture can drop down onto other surfaces in the attic, causing water damage and mold. In order to prevent moisture issues, it’s imperative to use perforated radiant barriers.
Are attic fans a good idea?
Attic fans do really work. They will help to circulate air in your attic and ventilate the space so that it stays closer to the outside temperature. Attics can reach extremely high temperatures in hot, summer months and gather an excessive amount of moisture in the winter. Attic fans will help fight these problems.
Is a radiant barrier worth the money?
Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it’s usually more cost-effective to install more thermal insulation than to add a radiant barrier.
Will radiant barrier damage shingles?
The short answer is NO damage will occur. Tests have shown that installing a radiant barrier in attics generally only cause the roof and shingles to increase about 2° – 10° Fahrenheit. Once the heat is absorbed by the shingles, it is transferred via conductive heat flow to the roof deck.
Does radiant barrier hurt shingles?
By blocking the mass insulation from absorbing heat and emitting it back to the roof, a radiant barrier can decrease the roof temperature at night by over 5 degrees. In short, radiant barrier should not void any shingle manufacturer’s warranty and will not damage roof shingles or any other roofing material.
Where should attic radiant barrier be installed?
There are two methods for installing radiant barriers – on top of the attic floor and on the underside of the roof. If you don’t use your attic for living or storage, you could install radiant barriers on top of the floor. Just be sure to never walk on them as you could miss a floor joist and put your foot through the ceiling below.
What is an attic radiant barrier?
A radiant barrier is a reflective and insulated coating that is applied to homes, usually in attics, with the sole purpose of reducing the amount of heat that is able to enter into the home. It does this by limiting something known as radiant heat gain, or the process by which a solid object absorbs heat.
How does radiant barrier work in attics?
A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. A radiant barrier works best when it is perpendicular to the radiant energy striking it. Also, the greater the temperature difference between the sides of the radiant barrier material, the greater the benefits a radiant barrier can offer.
In short Yes, Attic Radiant Barrier Does Work!! We only say radiant barrier doesn’t work because we know of a product that works even better and can save you over twice as much as current radiant barrier technology.
