A method and apparatus for producing a fibrous material product by advancing a mat of glass fibers arranged in laminations extending at least substantially parallel to opposite major surfaces of the mat along a gap extending between successive driven conveyors which engage the opposite major surfaces of the mat to control the advance of the mat along the gap, and driving the conveyors at progressively slower speeds along the gap so that the laminations are deformed in at least two separate stages into a reorientation in which at least a major portion of the laminations extend across the thickness of the mat. The resulting product has an improved compression strength.

Process and apparatus to crimp fibres

A bale of elongated flexible bags of generally rectangular section each contains one or more batts of fibrous heat insulating material, the bags being aligned in a row with larger faces in mutual contact. A sleeve of flexible relatively non-extensible material having a width which is a substantial proportion of the length of the batts extends around the row of bags and retains the fibrous heat insulating material in a compressed state in which the uncompressed volume of the heat insulating material is reduced but which results in substantially full recovery to the uncompressed volume when the heat insulating material is removed from the bags after the wrapping sleeve has been removed.

Bales of bagged batts

A glass fiber board product exhibits substantially improved compressive strength and is formed from a laminar mat of glass fiber containing a bonding substance. The mat is processed to rearrange the laminations of the mat so that at least a major portion extends across the thickness of the mat and the mat is then heat-cured and cut perpendicular to the major surfaces of the mat to form strips having opposite longitudinal cut faces. The strips are adhered together in side-by-side relationship to form boards with the cut faces forming opposite major surfaces of the boards. A backing sheet may be adhered to one or both sides of the board. Alternatively, boards cut from the cured mat are adhered together in stacks, which are then cut perpendicular to the boards.

Reoriented glass fiber board product

An exterior insulation layer secured to an above-grade portion of a building basement is protected by a protective sheathing, preferably of impact resistant PVC or the like. The sheathing reaches about 6'-12' below the ground so that the fill of the wall holds the lower end of the sheet in place. The upper portion of the sheeting is directly or indirectly connected to the wall by nails or the like fasteners disposed at a location spaced inwardly of the plane of the exterior of the protective sheet. The advance is in the extreme simplicity and the resulting low cost of the overall insulation of the wall.

Thermal insulation structure

A metal building insulation system facilitates the installation of insulation in the roof and walls of a building from the exterior of the building and employs channel members fitted over outwardly facing flanges on the structural members from the exterior of the building, the channel members having opposed side walls for receiving the structural members therebetween and intermediate walls connecting the side walls. At least one layer of insulating material is retained between successive structural members by means of projections extending outwardly from the side walls of the channel members and inwardly facing flanges on the structural members.
