摘要：

According to this method for improving the thermal insulation of existing buildings, and new buildings glazed, closed at its surface, air-filled balls are made of expanded silica sand or expanded perlite dilute phase pneumatic conveying means of a pump cart (1) with a hose (3) and nozzle (4) in the voids and cavities (5,6,7) injected an existing Bauwerkes and these are filled out. In a variant, these balls are pumped in combination with cementitious binders by means of thick phase conveying in these cavities and interstices. The blocks with cavities and interstices are also treated for their insulation property by a mixture of cementitious binders and expanded silica sand or expanded perlite be pumped into the hollow and intermediate spaces, and these are filled with it. yet these backfilled components have a virtually unchanged weight, but are much more thermally insulating than without backfilling.
