AtticFoil Perforated Radiant Barrier:

If you are shopping for foil, vendors call the product many different things. For example, another vendor labels their 13 lb product "Premium". Here is a little secret. They all have the same 99% pure aluminium foil on either side. The main difference is the scrim which is the inner layer. The heavier the scrim the stronger the foil. Don't be fooled by the name, go by the WEIGHTof the product. I ONLY sell the heavyweight foil insulation. Here is the summary:

  Weight Thickness
Standard Foil (competition) 14-16 lbs per 1000 foot roll 1.3-1.5 mils
Heavyweight AtticFoil (ours) 28-29 lbs per 1000 foot roll 5 mils

This was a little experiment set up just to show how strong the foil is. The foil is stapled on the 2x4 board with THREE staples. Then, a 25 pound dumbbell was hung with a coat hanger through the middle. The staples held the dumbbell and the hole with the coat hanger barely stretched.

What does this mean? It can easily be cut with a knife, but once in the attic you can staple one end, pull the foil across a section, staple the other end and then fill in a few more staples. This means a faster less hassle installation. Plus, it will never sag or fall down due to age and windy conditions.

Radiant barrier insulation is a reflective insulation system that offers a permanent way to reduce energy costs. Radiant barrier insulation reflects radiant heat energy instead of trying to absorb it. A pure aluminum radiant barrier will reflect over 97% of the radiant heat entering your attic and then your living area. Radiant Barrier has NO R-Value. But since it acts like "shade" it makes existing insulation more effective.

Your house is basically a box sitting in the sun. Radiant barrier acts like shade and actually reflects the heat from the sun away. The air outside is still hot and that won't change. What we can do is REDUCE the HEAT GAIN into the house. Remember, Air Conditioning is really just the REMOVAL of heat from inside the home. It makes sense that if we can REDUCE the amount of heat coming IN, then we will SPEND LESS on energy to get the heat OUT. (Energy Savings) This is NOT kitchen foil (kitchen foil is thin and will tear very easily if applied in an attic. And some kitchen foil is not pure aluminum, this is 99.5% pure aluminum).

One product that is gaining popularity is Radiant Barrier Spray. It can be a good product if applied correctly. However, depending on the brand, installation technique and the individual installer it will Never get even close to reflecting 97% of the radiant heat like the foil barrier.
