Air flow is reduced through a structure insulated with one more layers of fiber wool or particulate insulating material. A layer of a foamed fluid polymeric composition is applied onto the exposed surface of the insulation to cover the edges at which the exposed surface of the insulation meets an enclosing member of the structure. The layer is then cured to form a polymeric coating on the exposed surface of the insulation. The coating seals the edge or edges at which the exposed surface of the insulation meets the enclosing members of the structure.

A loosefill insulation installation includes a loosefill insulation material made from fiberglass fibers. The loosefill insulation material unexpectedly has improved thermal performance, even through the amount of mineral oil applied to the fiberglass fibers is reduce. For example, the fiberglass fibers can be coated with a mineral oil in an amount that is between 0.1% and 0.6% of the weight of the fiberglass fibers, such as about 0.375%.

The present invention relates to a thermal insulation material comprising graphite oxide particles, and also to the use of partially oxidized graphite oxide particles as an opacifying agent in a thermal insulation material.

A formaldehyde-free sizing composition for products based on fibers, in particular mineral fibers, such as glass or rock fibers, which includes at least one humic acid and/or one fulvic acid or a salt of these acids, at least one saccharide, and at least one inorganic acid ammonium salt.

A new prefabricated wall panel is the basic unit of a new, more efficient and stronger wall system. The wall panel is manufactured from a plurality of foam sections sized to leave vertical and horizontal voids into which concrete is later poured, each foam section having an inner and outer surface and two sides; and a plurality of fastening strips. The fastening strips are longitudinal metal strips being situated between the sides of two foam sections. Each fastening strip has two longitudinal fastening strips projecting perpendicularly to the longitudinal fastening strip and the fastening strips being adjacent to the outer surface of the two foam sections. The fastening strip also has a plurality of clearance holes in the longitudinal fastening strip, a plurality of embed tabs projecting from the edge opposite the fastening strips, each embed tab having at least one hole, and between each pair of embed tabs, a foam tab to hold the two inner sides of the foam sections in place and partially separate the foam sections from the concrete to be poured into a form.

This disclosure relates to an insulative system and materials therefor comprising a polymeric composition disposed at the junctions of the framing and exterior sheathing. In particular, an insulative system and materials therefor comprising a polymeric composition in the form of a sealing structure in contact with both the framing and exterior sheathing of a building are described.

The present invention concerns a columns assembly for an insulating wall of a building structure, said column having a side surfaces adapted to receive and retain insulation panels of the insulating wall, said column assembly comprising an inner spacer element made of mineral wool fibers, a central element made of mineral wool fibers, an outer spacer element made of mineral wool fibers, wherein the spacer elements are assembled with first and second intermediate profiles between the spacer elements, and wherein the density of the mineral wool in the central element is higher than the density in the inner and outer spacer elements. The invention also concerns an insulating wall assembly of a building structure with such a column assembly and a method of constructing such insulating wall.

A method for the manufacture of mineral wool products is disclosed. In one example, the method comprises reacting an aqueous phenol-formaldehyde resole with free formaldehyde with a first amount of urea, thereby preparing a prereact. The prereact is contacted with a second amount of urea. The resulting mixture of prereact and second amount of urea, as part of a binder, optionally with additives is applied to the surface of mineral fibers. The binder is cured on the surface of the mineral fibers. A mineral wool product with reduced emissions of formaldehyde is also disclosed.

An insulation system includes insulation support wires connected to wooden structural members that support roof sheathing. Insulation batts are disposed between the wooden structural members and on the insulation support wire. Portions of the insulation batts are disposed directly under bottommost surfaces of the wooden structural members.
