As we have stated earlier, the predominate areas of energy loss is straight through the attic space. So whatever we can do to reduce this loss will save a lot of energy. What is not commonly known is that energy is lost through several different means. One of which is convection – the principle of warm air rising and cold air descending – the other is conduction – what happens when the frying pan meets the stove top – and another radiation – the heat you feel when on a beach that also causes sun burns – and lastly leakage.

Most attic insulation is designed to reduce the flow of energy loss primarily through the process of conduction, but not radiation, convection or air leakage. This is why the use of cellulose or fiberglass insulation alone is not sufficient. Both fiberglass and cellulose (or other highbreds) will themselves conduct energy. This is why after a hot day when the sun has gone down and it’s later in the evening it is still hotter than blazing saddles in the house. The insulation in the attic space has absorbed heat (conduction) and radiates it back into the house. In the middle of summer many attics can get as hot as 150 degrees or more depending upon where one lives.

This is why thermal reflective multi-layer insulation is so effective combined with the proper accumulation of standard cellulose or fiberglass insulation. Thermal reflective insulation was developed by NASA and used primarily for space exploration to keep astronauts safe from harmful radiation. But today it has been used in many different applications for its solar reflective properties. And one of which is thermal reflective attic insulation.

Thermal reflective attic insulation is made of an aluminum sheathing. In some products it has two sheathes sandwiched between air pockets or other materials. Because aluminum reflects up to 97% of all radiant heat it is quite effective at keeping this form of heat source out of the attic. However, some products are better than others.

Single sheathed radiant barrier insulation has no real “R” value properties (resistance value of heat passing through an object), and nor does the double sheathed products – although slightly better. Furthermore, many of these products trap moisture in the attics. This of course creates mildew and mold issues which are hazardous to one’s health. In addition, some products are not flame retardant, but are in fact very combustible.

The products we use are permeable which means they won’t trap moisture. They are flame retardant. And they are double sheathed with aluminum and an interior core that is insulative with an “R” value rating of around R11. This provides maximum benefit for the attic areas. We also use it in new construction for outside walls, under the floor joists, wrapping hot water heaters and heat ducts, etc. Other products incorporated with our multilayer thermal reflective attic insulation are solar attic fans, outlet insulators, thermostats and more.
