Method of placing insulation in hollow building block involves forming strips and pushing them into hollow

摘要

The method of placing an insulation in a hollow building block or tile involves forming rectangular strips of the mineral fibre insulation (7) cut from a web. The web strips have the fibre axes running parallel to the upper faces (9) and side faces and at right angles to the front face. The mineral fibre web, prior to cutting is divided into plates (2) with their longitudinal axis perpendicular to the longitudinal axis of the web. The strips are pushed into the building blocks.
