Abstract (en)
A method of introducing insulating material or other air-entrainable material into an open recess or channel e.g. in a panel frame 59, includes applying to said recess or channel a filling head means 54 having a cover plate means 74 associated therewith, thereby temporarily to cover said recess locally to define a local cavity. A blown mixture of air and insulating material or other air-entrainable material is introduced into the cavity from the filling head means whilst leakage of the insulating material or other air-entrainable material is prevented. This is typically achieved by providing an extended cover plate such that the accumulated friction between the air-entrainable material and the cover plate and the walls of the recess is sufficient to prevent or substantially reduce leakage. The recess or channel is caused to move relative to said filling head means 54, progressively to fill said recess or channel. <IMAGE>
