HEAT-INSULATING MATERIAL AND MANUFACTURING PROCESS THEREFOR, AND INSULATION METHOD

WIPO Patent Application WO/2014/087834

A1

Provided are: a heat-insulating material which can achieve excellent heat insulation even in a case where there is not enough space to fill a heat-insulating material; and an insulation method using said heat-insulating material. A heat-insulating material (1) comprising a rigid polyurethane foam (20) and a vacuum heat insulation material (10) which is embedded in the rigid polyurethane foam (20), wherein: the vacuum heat insulation material (10) has an airtight outer bag (16) and a compact (14) formed by pressing a core material (12) which comprises a binder-bearing fumed silica (A') (12a) obtained by imparting a binder to the surface of fumed silica (A); the compact (14) is enclosed in the outer bag (16) in a reduced-pressure state; and the rigid polyurethane foam (20) has open cells. An insulation method which includes applying the heat-insulating material (1) to a construction surface.
