How Much To Install Radiant Barrier
One of the simplest and to the lowest degree expensive means to lower your energy costs and cool your house in summer is to install a foil radiant barrier insulation in your attic.
As discussed in the Insulation Buying Guide, radiant bulwark foil insulation is made of a thin sheet of aluminum or other reflective material laid over attic insulation or secured to the roof rafters. Designed to reflect the heat absorbed past a roof on hot, sunny days, radiant barrier foil keeps he attic air cooler and thereby reduces the amount of estrus transferred to the living spaces beneath.
Foil Insulation Installation
In an existing cranium, you can either staple rolls of foil radiant barrier insulation to the rafters or lay the foil out on top of the insulation. Attaching radiant barrier insulation to the rafters is the most effective method to employ, but both methods have their advantages and disadvantages.
Laying the radiant barrier on height of attic floor insulation is the easiest manner to install it, just information technology's more likely to get dusty that manner, and the Section of Free energy estimates that, as a radiant bulwark accumulates dust, its efficiency can exist decreased by upward to 50%. It besides makes navigating the cranium space more than dangerous, as you won't be able to easily identify where the roof joists are located. In addition, water vapor tin can condense on the underside and dampen the insulation, reducing its effectiveness and encouraging mold growth. If you decide to go with an attic flooring installation, make sure to purchase a radiant barrier that allows moisture to evaporate.
Attaching foil radiant bulwark insulation to the underside of the roof allows for better ventilation in the cranium—reducing heat buildup in the summer and removing dissentious moisture in the winter—and it does non obscure the location of joists. Still, it can reduce the life of asphalt shingles on your roof (since the heat is reflected out, shingles can become up to 10 degrees F. hotter than they normally would). You demand more than time for a roof-rafter installation than an cranium floor installation since information technology'southward harder than just laying radiant barrier over the insulation; plus, you need more materials as the area of a pitched roof is greater than that of the flooring.
Proper Installation Tips
With either installation, make sure the reflective material faces upward so it directs heat abroad from the house. For your own comfort and safety, endeavour to avoid installing information technology in the eye of the summertime, when your attic is at its hottest. Besides, having a helper will brand a relatively elementary job even easier. Have care non to cover vents or lighting, and be conscientious not to snag any electrical wiring.
Wear protective habiliment, a dust mask, and protective gear on your head as nails sometimes poke through the roof decking. If your attic is unfinished, use a piece of plywood laid on the roof joists to distribute your weight and help y'all navigate; otherwise, a wrong step could send you plunging through the ceiling beneath.
The cost of installing a radiant barrier depends on the type of insulation you have, the type of radiant barrier you choose, and whether you lot rent a contractor to do information technology or do information technology yourself. When purchasing the barrier itself, brand sure it'south rated Class A past the National Fire Protection Clan to encounter all building lawmaking regulations. Yous can buy radiant barrier online.
