Metal building insulation and vapor barriers. This video explains how bubble foil insulation is made from Mylar or metalized film. This is basically a potato chip bag. And, in 5-15 years in most metal buildings, the radiant heat and the UV from the lights will cause it to break down and disintegrate. This will allow the warm-moist air to to reach the cold metal and cause condensation. www.BlueTexInsulation.com is a superior product that uses pure aluminum rolls (instead of Mylar) and high density EPE or EXP foam instead of bubbles. This creates a product that will last, and won't dry out and become brittle. BlueTex Insulation also has a layer of tearproof woven fabric to make it more durable to tears and punctures. BlueTex Insulation can be used on both NEW metal buildings or EXISTING metal buildings.
