A heat insulator includes a foamed glass body, and a hollow member that stores the foamed glass body in a hollow portion. The foamed glass body is composed of a silicate glass material containing R.sub.2O compounds and RO compounds. In a case that a value A is a weight ratio (%) of the R.sub.2O compounds in terms of oxides to the whole, and a value B is a weight ratio (%) of the RO compounds in terms of oxides to the whole, an absolute value of a value C obtained by an expression of value A−2.08×value B is 5.27 or less, or an absolute value of a value D obtained by an expression of value A−2.68×value B is 3.23 or less.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

A wall system includes a framework having a first row of outer studs and a second row of inner studs spaced-apart and staggered from one another. A composite wall structure is supported by the framework and includes an exterior wall formation, an interior wall formation, and an intervening insulation system between the exterior and interior wall formations. The insulation system includes a pair of spaced-apart backing boards mounted to the framework. Foam insulation fills the cavity space between the pair of backing boards. The second row of inner studs are located in the cavity space and surrounded by the insulation.

A process for the manufacture of an insulating product based on mineral fibres bonded by an organic binder, includes applying a sizing composition to the mineral fibres, forming an assembly of the mineral fibres, heating the assembly of mineral fibres until the sizing composition has cured, wherein the sizing composition includes the following constituents within the limits defined below, expressed as fractions by weight with respect to the total weight of the composition: from 80% to 98% of water, from 2% to 20% of water-soluble poly(furfuryl alcohol) and less than 0.5% of furfuryl alcohol, and the mineral fibres are fibres of aluminosilicate glass including aluminum oxide, Al.sub.2O.sub.3, in a fraction by weight of between 14% and 28%.

An article comprising hollow ceramic microspheres and multi-component fibers is disclosed. The multi-component fibers are adhered together, and the hollow ceramic microspheres are adhered to external surfaces of the multi-component fibers. A method of making the article and use of the article for insulation are also disclosed.

The present invention is directed to a process for preparing an inorganic aerogel, the process comprising the steps of providing a composition (I) suitable to form an inorganic gel with a gelation time t.sub.G, spraying the composition (I) into supercritical carbon dioxide at a spraying time t.sub.S to obtain gel particles, and drying the gel particles obtained in step (ii) by supercritical liquid extraction, wherein the ratio t.sub.S:t.sub.G is in the range of from 0.2 to 0.99. The present invention further is directed to the inorganic aerogel as such as well as the use of the inorganic aerogel according to the invention in particular for medical and pharmaceutical applications or for thermal insulation.

A roof reflector system that is used to reflect solar radiation away from a rooftop. The system uses lines of flags that are strung across the rooftop in parallel rows. Each line of flags contains a plurality of flags that are aligned side-by-side. The flags are reflective to solar radiation. A common ribbon joins the flags into a line of flags. The base of each flag is coupled to the ribbon so that the flags hang away from the bottom edge of the ribbon. Brackets are provided that that can be selectively mounted to the roof. Each of the brackets has a connector that receives and retains the ribbon, therein supporting the ribbon at a first elevation above the roof. The length of each of the flags is greater than that first elevation. As a result, the flags touch the roof and fold along the roof, therein shielding the roof from the heat of the sun.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.
