Abstract
A method of constructing an assembly comprising an insulating fiber mass by pre-compressing the fiber mass to a controlled extent so that damage to the fibers is avoided, introducing the pre-compressed fiber mass into a cavity and releasing the pre-compression so that the fiber mass is retained under compression by the cavity wall.
Claims15
A method of constructing an assembly comprising an insulating mass of polycrystalline inorganic fibre within a cavity which comprises pre-compressing the fibre mass to a bulk density of 2 to 20 times its original bulk density by applying a removable binding agent to the fibre mass and mechanically compressing the fiber mass so that the binding agent retains the fibre mass in the pre-compressed state, introducing the pre-compressed fibre mass into the cavity and subsequently heating the fibre mass to remove the binding agent so that the pre-compression is released and the fibre is retained under compression by the walls of the cavity.
