This article explains what a cool roof is and how they work to reduce energy consumption. Solar reflectance and thermal emittance are the material properties that differentiate a cool roof from a conventional roof. Solar reflectance and thermal emittance determine the steady state temperature a roof will reach during a warm day. A roof’s steady […]

Stapling radiant barrier foil to the bottom of attic roof rafters improves the thermal performance of attic insulation in hot climates. Radiant barriers reduce radiant heat gain, which results in lower air conditioning requirements as well as energy savings. Radiant heat transfer Everything with a temperature greater than 0oK emits radiant heat. Radiant heat primarily transfers

Placing perforated radiant barriers directly on top of attic insulation in mixed and cold climates improves the thermal performance of insulation. Radiant barriers reduce heat loss caused by convective looping and wind washing which insulation alone may be susceptible to. Radiant heat transfer Everything with a temperature greater than 0oK emits radiant heat. Radiant heat

Adding more insulation in your attic is an easy way to make your home more energy efficient as well as reduce the cost of your utility bills. How attic insulation works Attic insulation reduces heat loss in the winter and heat gain in the summer by providing a barrier between the attic space and the
