Should I Insulate My Home With AtlasFoil?

If you have an older home, built twenty or more years ago, then your home likely doesn't have added or effective insulation. In fact, a recent survey shows that only 20% of homes built after 1980 are properly insulated. 

If your home seems uncomfortably hot in the summer, or too cold in the winter, insulation helps to creaste a more uniform temperature, increasing you and your family's comfort. Atlas Restoration uses a special AtlasFoil installation material that ensures the very best insulation for your home, all year round.

Ask An Expert: Do I Need AtlasFoil If My Attic is Already Insulated?

Professor Charles Shabica from Northeastern Illinois University says: "Reflective foil retrofitted to fiberglass insulated buildings is demonstrably effective in reducing heat loss... Insulation of foil in uninsulated buildings would show even more pronounced reduction in heat loss."

What is the "R" value of a radiant barrier such as AtlasFoil?

From Energy Design Update newsletter, the leading resource for developments and news related to energy-efficient construction and residential design: 

"One of the most surprising results obtained in the FSEC tests was the mutually enhancing effect of RBS's and attic ventilation. When they measured the "apparent R-value" of ventilated attic systems with and without radiant barriers, they came up with values of R-68 with the RBS and R-38 without RBS! ("Apparent R" is calculated from the temperature difference across the whole attic, from roof surface to ceiling below.)" (Energy Design Update, March 1986, Vol.5, No. 3).

What is Radiant Barrier Foil Insulation?

Foil insulation is typically installed in home attics to help reduce utility bills. Radiant barrier is preferred over other types of insulations because foil insulation reflects heat back to its source, while other types of insulation only slow down the transfer of heat. In a standard residential home, installing foil insulation in your attic can stop 95-97% of the radiant heat that hits its surface. More than that, foil insulation resists heat in the summer months and reduces heat loss during winter months.

How Does AtlasFoil Work in My Attic?

What Are Radiant Barriers?

Radiant barriers reduce heat transfer across air space between the attic floor and the roof deack by thermal radiation. All materials give off, or emit, energy by thermal radiation as a result of their temperature. On a warm, sunny day, solar energy is absorbed by the roof, heating the sheathing on the roof, causing sheathing's underside and the framing on the roof to radiate heat on a downward path to the attic floor. The installation of radiant barriers deflects the roof's heat back in the direction of the roof. This prevents unecessary amounts of heat from entering the house through the roof. In the winter months, radiant barriers may also lower indoor heat loss through the ceiling. Radiant barriers reduce the amount of energy radiated from the top surface of the insulation.

Attic Foil Blocks Heat Transfer, Keeping House Cooler

Expert Jim Dulley Answers A Client's Pressing Question About Attic Foils: 

Dear Jim: I have plenty of fiberglass insulation on the attic floor, but it still seems as though the bedroom ceiling is warm on sunny days. What can I do to keep it cooler? - Steve P.

Dear Steve: If you put your hand against the ceiling, you will be surprised by how warm it actually is. What you are experiencing is radiant heat transfer from the hot roof to the ceiling below. A dark roof can reach 150 degrees in the afternoon sun. Standard fiberglass insulation is effective for blocking conductive heat transfer, but not for radiant heat. Radiant heat from the roof penetrates through the insulation to the ceiling below. Even the insulation gets warm. The best method to block most of the heat is to install reflective foil underneath the roof and install adequate attic ventilation. The foil will block the direct path of the radiant heat to the ceiling below. The attic ventilation will cool the roof and carry the excess hot air away. In my own home, this combination lowered my bedroom temperature by 10 degrees. Attic foil is commonly referred to as reflective foil because it looks reflective. It actually works not by reflecting the heat back up to the roof, but by its low-emissivity (similar to low-e windows). The foil gets hot, but its shiny, low-e surface does not easily radiate the heat downward.  (
