Method for thermally and/or acoustically insulating buildings

Abstract

A method of insulating buildings which include a plurality of support members with adjacent support members being spaced a predetermined maximum distance from each other. A plurality of stacked insulation panels (or an insulation roll) is provided with each insulation panel being formed by a panel of mineral wool insulation material having opposite longitudinal edges spaced a predetermined distance from each other at least equal to the predetermined maximum distance between the adjacent support members. A vapour barrier sheet is carried by each insulation material panel (or an insulation roll) with opposite longitudinal edges being folded upon an exterior surface of a central portion of each vapour barrier sheet and being directed in opposing relationship toward each other thereby defining exposed opposite projecting longitudinal edge portions of each insulation material panel with the folded distance being sufficient for the subsequently unfolded vapour barrier sheet longitudinal edges to project beyond the insulation material panel longitudinal edges. The stacked insulation panels are enclosed in a wrap. Thereafter the wrap and at least one of the longitudinal edge portions of all of the insulation material panels (or insulation roll) is substantially simultaneously longitudinally severed inward of each of their longitudinal edges a distance which creates a severed edge-to-edge distance corresponding generally to a distance between adjacent support members less than the predetermined maximum distance.
