If you want to insulate directly on the appliances, we recommend our flame-retardant melamine foams Basotect® G+ Absorber, which are available with a wide variety of surface coatings, or our PUR recycled foams and our Teroform® plastic heavy layer/PUR foam combination noise insulation mats.
The first base layer of plastic heavy foil is very efficient, as these heavy foils not only deaden the metal, but also insulate sound. The above-mentioned materials are glued directly into the computer or server. If there is not enough space, you can encapsulate the devices and then attach the respective foams or heavy foils.
The thicker the panels, the better the insulation. The plastic or bitumen heavy foil as a base layer is always recommended here, as it considerably increases the insulating effect. Our acoustic foams made of Basotect® melamine foam are often used for this application due to their high level of fire protection.
