摘要
<p>The thermal insulation has two opposite half shells (2,3) of rigid foam, which lie between connections of an installation pipe (1). A contact surface of the half shell is fixed perpendicular to a wall stand at the installation pipe. The diameter of the half shells lie in nano range between 4 and 100 nanometer. The rigid foam is made of phenolic resin.</p>
