LESS is MORE when it’s BTUFOIL Metal Building Insulation

We have known the TRUTH for OVER 20 YEARS,

NOW its time for YOU to KNOW THE TRUTH

The following is an excerpt from Metal Building Review, March 1982, which discusses the unique benefits of using Reflective Foil Insulation IN PLACE of using fiberglass in the metal building market:

From an installer's point of view, foil insulation is a much better material than fiberglass for use in metal buildings - no holes to drill in trusses., wires to string, no problems insuring the crews arrive ahead of time to run insulation over tops of trusses before the roof is laid down. No itchy mess under clothing, and, best of all, no need for bulky protective wear during hot weather.

Foil, installed, costs fifteen to eighteen percent less than fiberglass of comparable R value; foil performs the primary task of insulating a building more efficiently; foil meets fire safety standards better than fiberglass; and foil can look better after installation than clumps of fiberglass batting suspended overhead.

Insulation's basic job to help maintain a set temperature level inside the building despite extreme variations of temperature outside. Since metal structures conduct heat well, insulation is a particularly important component in conserving energy and sustaining a comfort level for workers or temperature sensitive materials inside. Quality foil insulation, installed properly, meets this task far more reliably than fiberglass.

These are sweeping claims for foil insulation that only a short time ago couldn't have been seriously made. It took major developments in the design and fabrication of foil isolation to make the product really usable. Now, foil should be getting a close, second look.

There are two reasons for foils performance advantages: first, fiberglass installation procedures tend to defeat the very properties that make fiberglass an effective insulator; and second, condensation of moisture, common to metal structures in particular; substantially reduces fiberglass's ability to interrupt the conducting of heat.

Fiberglass works as an insulating material by creating air spaces within its bulk. If the batting is compressed, the fiberglass becomes a conductor instead of an insulator.

Increasing the mass of fiberglass insulation doesn't compensate, because its effectiveness diminishes as the mass increases. Fiberglass, as a material, is a relatively good conductor, yet by use of air spaces, slows the transfer of heat-but a substantial thickness of fiberglass will transmit heat through the material itself

This is a partial explanation of why ratings tests on fiberglass rarely match ratings produced after the product is installed in a field location and tested again.

The original rating supplied by the manufacturer is based upon a test of one inch thickness, then extrapolated for three, four, or five inches thickness of the material. However, as explained above, piling on the fiberglass adds very little additional insulating value, so the extrapolation method is invalid, and the R value from the manufacturer is exaggerated. Additional R values are tested at a moderate temperature. As temperature changes, the values change by geometric proportions.
