Abstract:
An improved board material is provided comprising a set cementitious core bearing on at least one of its surfaces as a facer a multilayer nonwoven fibrous mat of a specific structure. The outer layer of the mat comprises fibers of a fine diameter of approximately 1 to 10 microns and the inner layer of the mat comprises coarser fibers having a greater diameter (e.g., approximately 12 to 30 microns and preferably approximately 15 to 20 microns). The outer surface is relatively smooth and is aesthetically pleasing. The coarser fibers of the inner surface provide interstices between adjoining fibers so as to promote the ingress of the cementitious core prior to setting with the achievement of enhanced adhesion between the set cementitious core and the multilayer nonwoven fibrous mat.
Abstract:
Disclosed is a waterproofing membrane that comprises a carrier sheet (layer A); a waterproofing adhesive (layer B); a protective coating (layer C), wherein the protective coating is substantially free of surfactant and comprises an acrylic or methacrylic polymer or copolymer, an inorganic filler and a white pigment; and a releasable material (layer D), wherein the releasable material comprises amorphous nanoscale silica and a polymeric binder. The waterproofing membrane does not require a release liner, binds strongly to concrete cast against it (even after UV exposure), tolerates foot traffic, and withstands immersion in water over an extended period.
Abstract:
An insulator element comprising at least a first layer (1) of insulating material, which is a thermal insulation formed of synthetic polymer material. The element also comprises a second layer (2) of insulation material, which is waterproofing, and a third layer (3) of insulation material, which is provided between the first layer (1) and the second layer (2) of insulating material, to separate them. The invention also relates to a method for forming an insulator element, as well as a roof structure formed of insulator elements joined to each other.
Abstract:
A waterproofing membrane comprising a structure incorporating a fibre layer and wherein to one side of said structure a bituminous mass is applied and another side of said structure is covered on its surface with a substance comprising a mineral or organic filler and an acrylic polymer, whereby said substance comprises between 15 % and 25 % by dry weight of said acrylic polymer and mixed therewith between 4 % and 22 by dry weight of titanium dioxide.
Abstract:
A fungi resistant asphalt (14) is combined with a base sheet (12) to form a fungi resistant asphalt containing sheet material (10). Typically, the base sheet (12) is a fibrous base sheet (12) that, by itself, may or may not be fungi resistant. The fungi resistant asphalt (14) is at least partially absorbed by the base sheet (12) to form the fungi resistant asphalt (14) containing sheet material and typically forms one or both major surfaces of the fungi resistant asphalt containing sheet material (10).
Abstract:
Ein Bitumenfugenband, bei dem in Einbaulage der obere Teil aus einem wasserundurchlässigen, bitumenhaltigen Material und der untere Teil aus einem wasserdurchlässigen Material besteht, kann zum Schließen von Fugen in Deckschichten aus Asphalt verwendet werden.
Abstract:
This roof-boarding, roof lining or wind bracing board has a substantially water-tight but steam-permeable foil (1) protected on both sides by two non-woven plies (2, 2'), preferably made of polypropylene, and joined to a glass and/or plastic fabric (7) impregnated with bitumen (5). This layer is covered by a plastic fibre non-woven ply (6), preferably of polypropylene. The glass and/or plastic fabric (7) highly increases mechanical strength and the bitumen (5) improves water-tightness, in particular in the area of the fastening points (nails). Owing to the openings between weft threads (3) and warp threads (4) of the glass and/or plastic fabric (7), no steam-tight bitumen layer is obtained. Instead of the glass and/or plastic fabric, a needle felted glass and/or plastic non-woven ply may also be used.
Abstract:
A composite membrane comprising a first layer comprising an adhesive composition and a second layer comprising a mesh, wherein the mesh is directly embedded in a surface of the first layer of adhesive with areas of the adhesive composition exposed through apertures in the mesh, the mesh having between 10 and 30 warps/100 mm and between 10 and 30 wefts/100 mm.
