It's More Than Just an Attic, We Know and so Should You...
10 YEARS OF ATTIC INSULATION EXPERIENCE
Attic Insulation… Did you know that warm air moves toward cold air? Part of what makes our Efficient Attic Insulation System so effective is correctly-installed attic insulation. It keeps the air between your attic and your air-conditioned living spaces separate.
By decreasing this heat transfer, attic insulation lowers your energy costs and puts less strain on your heating and cooling system. And the benefits are year-round. In winter, the heated air in your house stays put, instead of rising into your attic. In summer, your hot attic air stays in the attic, instead of seeping into the cooler living areas. Our customers love to discover that the added insulation often makes their homes quieter, too!
The Importance of space
When installing a foil-type barrier, it’s important to allow the material to “droop” between the attachment points to make at least a 1.0 inch (2.5 cm) air space between it and the bottom of the roof. This air space has mainly two functions: it creates an air channel for the soffit and ridge ventilation system to work more effectively, and it acts as a second reflector since there are two shiny sides (one facing up/ one facing down.)
The proper way
Some builders also try to attach the radiant barrier directly onto the roof sheathing prior to their installation on the roof rafters. However, a more effective method is to simply buy foil-faced plywood or oriented strand board sheathing instead. There are also metal roof shingles that have a reflective underside. If you need roof shingles, these are a practical option, but the cost of this type of radiant barrier is considerably higher than other types.

When the sun heats a roof, it’s primarily the sun’s radiant energy that makes the roof hot. A large amount of heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates the gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor. The barrier material works as a reflector for heat and is very effective if installed properly. When this technology is applied to existing buildings it can drastically reduce the cooling load for heating, ventilating and air conditioning equipment (HVAC) thereby increasing energy efficiency as a whole.
Don’t confuse this material with attic insulation. A radiant barrier assists the thermal boundary (insulation). This material by itself will not help to retain heat. It primarily only reflects it. As insulation works to slow the transfer of heat, the radiant barrier assists by reducing the amount of heat the attic insulation layer is exposed to.
Fiberglass Attic Insulation
Installation of blown-in fiberglass insulation is usually used in attics that are unfinished. This method is very affordable and most jobs can be completed in a day or so.
Blown-in Cellulose Insulation
Installation of blown-in cellulose is a great insulation for a couple of different reasons. First its environmentally friendly. Second its very affordable and is a quick install.
Spray Foam Installation
Spray foam insulation will stop air flow and it stays in one place forever. Its used most commonly when a home owner wants to seal off the attic for storage or a living space.
Radiant Barrier Foil Paper
Radiant Barrier is an aluminum sheet that reflects heat from the suns rays. It helps to decrease the temperature in the attic which can potentially lower energy costs.
Frequently Asked Questions
What is Radiant Barrier?
Radiant barrier is installed in homes – most commonly in attics – to reduce summer heat gain and winter heat loss, which helps lower heating and cooling costs. This barrier consists of highly reflective material that reflects radiant heat rather than absorbing it. It doesn’t, however, reduce heat conduction as thermal insulation materials do.
How Does it Work?
Heat travels from a warm area to a cool area by a combination of conduction, convection, and radiation. Heat flows by conduction from a hotter material to a colder material when the two materials touch. Heat transfer by convection occurs when a liquid or gas is heated, becomes less dense, and rises. Radiant heat travels in a straight line away from the hot surface and heats anything solid as the wave of energy hits it.
When the sun heats a roof, it is primarily the sun’s radiant energy that makes the roof hot. A large portion of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy into the cooler attic (some of the roof’s heat will radiate in other directions too). A radiant barrier reduces the radiant heat transfer from the roof to the attic space.
Where can it be installed?
Radiant barrier can be installed between the roof sheathing and attic floor insulation, in cavity walls, and around door openings, water heaters, and pipes. It’s easier to incorporate radiant barrier into a new home, but you can install them in an existing home too.
How is it installed?
An installer typically drapes a rolled-foil radiant barrier foil-face down between the roof rafters to minimize dust accumulation on the reflective faces (double-faced radiant barrier is available). This is generally done just before the roof sheathing goes on if it’s not too windy, but it can also be done afterwards from inside the attic by stapling it to the bottom of the rafters.
How much can I expect to save after the installation?
Radiant barrier is more effective in hot climates than in cool climates. Some studies show that radiant barrier can lower cooling costs between 5%–10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. But in cool climates, it’s usually more cost effective to install more than the minimum recommended level of insulation rather than a radiant barrier.
Are there other types of radiant barrier
Radiant barrier comes in a variety of forms, including reflective foil, reflective paint coatings, reflective metal roof shingles, reflective laminated roof sheathing, and even reflective chips, which can be mixed with loose-fill insulation. The reflective material, usually aluminum, is applied to one or both sides of a number of substrate materials. Substrate materials include kraft paper, plastic films, cardboard, plywood sheathing, and air infiltration barrier material. Some products are fiber reinforced to increase the durability and ease of handling.
Also, radiant barrier – which dosen’t provide a significant amount of thermal insulation – can be combined with many types of insulation materials. These combinations are called reflective insulation systems. In these combinations, radiant barrier can also act as the insulation’s facing material.
Guys were great and very detailed about the whole process. I’m sure I will start to see my investment pay off now that I took care of my insulation problem. I also had them install the radiant barrier sheet and I’m getting excited to see my next electricity bill.
I highly recommend this company. They were prompt and very helpful with my 101 questions and concerns. I can’t believe how quick they had the job done.
I was looking for an affordable solution to help me cut costs and AB was referred to me by a realtor who uses them on their properties. Glad I found this company. A++
