Construction method using insulated waterproofing complex sheet with excellent insulation, insulation, waterproofing and condensation prevention

摘要

The present invention is an airgel-impregnated nonwoven fabric sheet layer; and a thermosetting regenerated polyurethane sheet layer superimposed on the airgel-impregnated nonwoven fabric sheet layer; to a waterproof construction method using a thermal insulation waterproof composite sheet having excellent insulation, heat shielding, waterproofing and condensation prevention, including. According to the present invention, by including the airgel-impregnated nonwoven sheet layer, a sufficient air layer is additionally secured to provide excellent insulation, heat shielding, and waterproofing effects, as well as easy bonding with the thermosetting regenerated polyurethane sheet layer, and improved background control material It is chemically stable, has excellent compressive strength, cures quickly, can be constructed even in sub-zero temperatures and in wet conditions, exhibits excellent adhesion to the floor, and provides breathability through which moisture from the floor permeates and is discharged. It may have a Gore-Tex performance having waterproofness that does not penetrate the upper part of the water while having it.
