<p>Thermally and acoustically insulating "lost" bearing shuttering elements for building skeletal frameworks such as bearing walls, crossing or parallel joist ceilings, with absolute precision of assembly, has a flat rectangular bearing surface of strong, expanded, synthetic resin having on one face two projections forming mould partitions, which are parallel, sepd. by a distance equal to their projection length. The material forming the shuttering can be made to serve a useful purpose in the building other than just the moulding of the concrete as in prior art.</p> |
