The invention relates to a vapor barrier for use in cthe thermal insulation of buildings which can be used, in particular, for thermal insulation procedures in new buildings or in the renovation of old buildings. The vapor barrier in accordance with the invention is thereby capable of achieving water vapor exchange under different ambient conditions. This is achieved by using a material which has a water vapor diffusion resistance which is dependent on the ambient humidity and which also has adequate tensile strength and tear resistance.

A failure resistant, flame retardant vapor barrier facing for insulation is disclosed. The facing is comprised of a coating and a backing. The coating comprises a pair of coextruded composites each composite comprised of FR material, UV blocking material, pigment material and a polyolefin (e.g., LDPE). The backing is a woven substrate woven from flame retardant polyolefin (e.g., HDPE) tapes. The woven substrate is laminated to building insulation using an adhesive. The woven substrate lends strength, flexibility and form to the facing.

The invention discloses a fiber-reinforced fireproof insulation board. The fiber-reinforced fireproof insulation board is prepared from the raw materials in parts by weight: 80-100 parts of fly ash, 30-50 parts of expanded perlite, 10-20 parts of ceramsite, 10-20 parts of plant fiber, 5-10 parts of floating bead, 5-8 parts of meerschaum, 3-5 parts of sodium fluosilicate, 3-5 parts of calcium formate, 3-5 parts of flame retardant, 0.1-0.5 part of oleic triisopropanolamine and 0.1-0.3 part of glycol dimethyl ether. According to the fiber-reinforced fireproof insulation board, industrial production wastes are adopted as main raw materials, so that the production cost is reduced; through the organic combination and generated synergism of the fly ash, lightweight aggregate and additives, the defects in the existing building insulation boards can be effectively overcome.

A system and method are provided for insulating a vertically extending wall (e.g., concrete wall). First and second supports are first attached to the vertical wall at respective first and second vertically spaced locations (e.g., proximate the top and bottom of the wall). After the supports have been attached to the wall, a blanket(s) of rolled fiberglass insulation (e.g., metal building insulation) is attached to the wall between the first and second supports. Then, a flexible sheet of vapor retarder is attached to protruding portions of the first and second supports so as to cover the blanket(s) of fiberglass insulation thereby causing the blanket of fiberglass insulation to be partially or fully hidden from view and retained in the cavity defined between the vertical wall and the vapor retarder.

A preparation method for A-level fire-protection energy-saving rubber-plastic thermal-insulating compound foam comprises the following steps: adding polypropylene powder resin, methyl vinyl base silicone rubber, ceramic powder, a fire retardant, glass fiber powder, an antioxidant, white carbon black and polyethylene wax in a high-speed mixer for kneading at a normal temperature, discharging the kneaded materials to an internal mixer so as to obtain material groups through internal mixing, discharging the material groups to a single-screw extrusion pelletizer so as to obtain a basic material A through melting, plasticizing and granulation; adding low-density polyethylene resin in a high mixing machine, then adding an AC blowing agent, talc powder, a lubricating agent and zinc stearate for kneading at the normal temperature, and then discharging the kneaded materials into a single-screw extruder so as to obtain a foaming masterbatch B through granulation; adding the basic material A, the foaming masterbatch B and the polyethylene wax into the high-speed mixer for kneading at the normal temperature, and then discharging the kneaded materials into the single-screw extruder so as to obtain sheets through extruding; carrying out irradiation crosslinking and foaming; grooving on the surface of the prepared foam; and embedding fire-protection filler in the grooves of the foam, immersing in a fire retardant solution and baking so as to obtain the compound building foam.
