Abstract
A non-planar formed body of particulate insulating material is made by first compacting substantially inorganic non-fusible particulate insulating material to form a plane panel. Covering material such as glass cloth coated with a settable composition or thermoplastic material effectively comprising a settable composition, is disposed adjacent one or both faces of the plane panel, in a mould. The mould is then operated to form the panel into the desired non-planar form, and the settable composition is allowed to harden.
Claims18
A method for making a non planar formed body of particulate insulating material, comprising the steps of:
- compacting substantially inorganic non-fusible particulate insulating material in a first forming means to form a planar panel constituting a body having opposite faces;
- disposing covering material coated with or comprising a settable composition adjacent at least one said face of the planar panel, in a second forming means;
- operating the second forming means to reshape the body of the panel into the desired non-planar form;
- and
- allowing the settable composition to harden.
A method for making a non-planar body of particulate insulating material, comprising the steps of:
- compacting substantially inorganic non-fusible particulate insulating material in a first forming means to form a planar panel defining a body;
- disposing covering material coated with or comprising a settable composition in a second forming means;
- disposing the planar panel on the layer of covering material;
- operating the second forming means to form the body of the panel into the desired non-planar form;
- and
- allowing the settable composition to harden.
