Abstract
A free flowing thermal insulation which may be installed by auger feeding, blowing or pouring is disclosed. Granular material having a requisite K value (e.g., 0.20-0.315 BTU-in/.degree.F-ft.sup.2 -hr) is a major component of the insulation and is thoroughly mixed with a minor component of fibrous thermal insulating material to form a mixture which is used to provide the thermal insulation. Also included in the thermal insulation is a dust suppressant in quantities as required.
Claims31
A dry free flowing thermal insulation suitable for installation by auger feeding, pouring, blowing or other similar means comprising a dry, free flowing mixture comprising a major amount of granular thermal insulating material mixed with a minor amount of fibrous thermal insulating material.
A dry free flowing thermal insulation suitable for installation by auger feeding, pouring, blowing or other similar means comprising a dry, free flowing mixture comprising approximately 10 to 20 weight percent glass fiber blowing wool nodules having a respresentative diameter of approximately 0.25 inches, 80 to 90 weight percent expanded perlite granules having a loose density of 2.5 to 3.0 pcf, and approximately 5 to 10 weight percent of the weight of the glass fiber and perlite of ethylene glycol.
In a method of insulating an area by distributing a dry free flowing thermal insulation by auger feeding, pouring, blowing or other similar means into a cavity adjacent the area to be insulated, the improvemennt comprising:
- (a) mixing a major amount of a granular thermal insulating material with a minor amount of a fibrous thermal insulating material, and
- (b) distributing said resulting thermal insulation into said cavity.
A sidewall cavity defined by inner and outer wall structures and two sequential vertical studs provided with thermal insulation said thermal insulation comprising a dry free flowing thermal insulation suitable for installation by auger feeding, pouring or blowing or other similar means and having a major amount of granular thermal insulating material mixed with a minor amount of fibrous thermal insulating material.
