It’s simple; it is the heat energy that is constantly radiating through the air space. If a surface is warmer than the air space around this area deliver heat as caloric rays through the air space. These rays are invisible, but very powerful. Consider internal temperature in a range between 65 and 85 ˚ C when the outdoor air has a temperature of about 35 ˚ F. This is because the Sun, has saturated the roof deck with intense radiant energy, and precisely this saturation is the one that allows the passage of this energy to internal, staying this internal in the dark, but with a lot of concentrated heat energy.

Now consider what happens in a building with metal roof and structure. It is a fact that the roof deck absorbs the sun’s radiant energy continually throughout the day. We know that energy can neither be created or destroyed, only transformed or redirected, therefore the metal cover that delivers heat to the interior of the building in the form of invisible energy beams. This energy manifests itself in heat, only when it hits objects inside the building, including people or animals that inhabit it, with the results in the environment we all know.

This type of radiant energy that is moving into the building from outside, is insensitive to traditional mass insulation, whether polyethylene or polyurethane foam, fiberglass, etc.., Since these materials are designed to absorb and retain other types of energy transfer. However, this energy can be controlled with aluminum. The metal, possesses the ability to redirect, not fight them, these invisible rays. This is the reason why aluminum is commonly used to isolate planes, the space shuttle and even the space suits used by astronauts, since without these reflective materials, an astronaut would perish in space.

Why Double Bubble Insulation?

If air bubbles radiant double bubble insulation have air inside at the time of installation, this air will remain trapped in them indefinitely. Double Bubble Insulation is produced under high quality production, with linear low density polyethylene, which is an excellent air barrier. Each air bubble, in addition to being built entirely independent of the others, is manufactured with an internal air pressure identical to the outside air pressure, where the equalization of forces that naturally prevents air from escaping. In fact, in addition, each air bubble is filled to 75% by volume, allowing the time of the conductive transfer, once installed, the volume of each can be increased by 25% for retention heat one square meter of double bubble insulation, has about 13,000 independent bubbles. As an example, the amount of double bubble insulation required to isolate a 150 m2 deck, might have a total of 3.1 million individual bubbles, each and every one of them independent of the others.
