Wavy-Insulating system

The wavy-insulating system is extremely light and cheap. It is based on a foil system that is wavy like the form of a washboard. Usually two layers of this foil are placed on top of each other. Since the structure of the individual layers are counterlayed, they cannot slide into each other and a safe distance in between is quarenteed. The locked in air insulates against heat and makes a sound insulation by means of the foils possible. A covering foil, with a thickness of approx. 0,05 mm, should seal this insulating package. The insulating system is layed directly on a supporting sheet. If heat insulation is wished, in addition to sound insulation, then the supporting sheet metal has to be perforated (25-30% hole share) and an absorbing foil with 0,02 mm thickness between the supporting sheet and the insulating package has to show for.

The heat insulation works:

• through the locked in air
• through the high reflections- and the low radiation strength coming from the shiny surfaces when the heat radiates
• through the side heat conductor by means of the good heat conductor, aluminium
• also through the little surface contact of the foils in the direction of the flowing heat.

Acoustical absorption:

• becomes possible, because the foils are very thin and air pockets are in between the layers.
• The pressure in our system is made possible, because the waves are stamped in wave form. This is essential.
• The foil system cannot support itself and needs for the stabilisation a supporter that, heat technically, needs to be designed to fit acoustically and statically. 

Applications

• Heat insulation
• Acoustical absorption in heated areas
• Insulating element on heat air shields near the exhaust pipes of automobiles
