Shaped insulating building-block above cellar walls - L-sectioned to accommodate concrete ceiling checking cold flow

摘要

The purpose is to inhibit the flow of cold, esp. through the basement, or cellar, masonry and concrete floor-ceiling, in residential buildings, by use of insulating shaped building-blocks, which may be made of gas concrete or similar materials. These are elongated units, of approx. L-shaped cross-section, to accommodate the concrete ceiling above the cellar, being installed between the external masonry wall and this ceiling. They pref. incorporate an expansion strip (8), which may be made of styropor, and sliding material, such as insulating paperboard, (a), fixed to the blocks in advance. The ends may be fitted with a tongue (10) or groove (11) for fitting together. They may also be used in connection with prefabricated floor-ceiling building.
