Thermally insulating fabric comprising a textile fabric layer which comprises fumed silica powder of average pore size 50 to 200 nm in an amount range of 1 to 70% w.

The present invention relates to inorganic fibres having a composition comprising: 65.7 to 70.8 wt % SiO.sub.2; 27.0 to 34.2 wt % CaO; 0.10 to 2.0 wt % MgO; and optional other components providing the balance up to 100 wt %,
wherein the sum of SiO.sub.2 and CaO is greater than or equal to 97.8 wt %; and the other components, when present, comprise no more than 0.80 wt % Al.sub.2O.sub.3; and wherein the amount of MgO and other components are configured to inhibit the formation of surface crystallite grains upon heat treatment at 1100° C. for 24 hours, wherein said surface crystallite grains comprise an average crystallite size in a range of from 0.0 to 0.90 μm.

A thermal break wood and rigid insulation stud is comprised of two non-dimensional lumber sections with a thermal break section of rigid foam insulation therebetween. A non-metallic truss arrangement of mechanical fasteners holds the lumber and insulation sections secured together greatly improving the strength of the thermal break wood and rigid insulation stud. The studs in a wall are 24″ on center. The studs are used for headers and sills and also may be used for top and bottom plates. The corners have an exterior all wood stud, an interior all wood stud and an interior all wood stud adjacent to the interior wood stud completing the interior corner for nailing gypsum board thereto. This corner has a thermal break space between the exterior and interior wood studs for insulation placement. The corners may also have two 3×6 thermal studs oriented 90 degrees from each other and an interior all wood stud for completing the interior corner for nailing gypsum board thereto. This corner arrangement also has a thermal break through its construction.

Provided is a system and method for a providing exterior insulation and finishing for a building. More specifically, the system for providing exterior insulation and finishing for a building, includes: backing material to be affixed to an exterior wall structure, the backing material suitable to receive closed cell spray foam; a reservoir of closed cell spray foam to be applied by a sprayer to the backing material when adjoined to an exterior wall surface; at least one shaping device structured and arranged to shape the closed cell spray foam after application to the wall surface; and a reservoir of weather resistant barrier material to be applied by a sprayer to the shaped closed cell spray foam. An associated method of use is also provided.

Mortise lock with an operating mechanism with a pinion that is turnable around a geometric axis and a rack engaging therewith that is movable along a direction perpendicular to the aforementioned geometric axis, whereby the pinion is provided with a double toothing with two sets of teeth that are separated by a geometric dividing plane that extends perpendicularly to the axial direction of the pinion, wherein the teeth of each set of teeth of the pinion form an oblique toothing, whereby the faces of these teeth are oblique with respect to the axial direction and these faces include an angle to one another that is such that the width of the teeth of each of the two sets of teeth either decreases or increases in the direction of the dividing plane.

The invention relates to creating health benefits from an energy efficient thermal insulation device of a reinforced impermeable aluminum sheet combined with a protective cover divided into a number of air filled square and rectangular shaped modules that provide health and comfort benefits by improving indoor and outdoor air quality and indoor air circulation by reducing energy flux through the building fabric where the insulating device is fixed to a wall or free standing behind a heat emitter and thereby reducing the heating fuel consumption and therefore storage requirements of heating fuel and thereby extending fuel reach for the fuel supplier and reducing carbon dioxide emissions into the atmosphere.

A method of forming a porous sol gel, including a dried porous sol gel, is provided comprising forming a sol gel from a sol gel-forming composition comprising a silane solution and a catalyst solution; and non-supercritically drying the sol gel to provide a dried porous sol gel having no springback. The dried porous sol gel can include dried macroporous or mesoporous sol gels or dried hybrid aerogels. The materials may contain open or filled pores. Such materials are useful as thermal insulators.
