A mechanism for supporting and positioning a glass floor unit relative to a base utilizing a support positioned to contact the glass floor unit. An adjuster interacts with a receiver fixed to the base. The adjuster includes a contact element which moves the support and exerts a force against the glass floor unit in an upward direction.

A fire-protection pane, including at least one float glass pane with an atmosphere side and with a tin bath side, at least one protective layer, which is arranged in a surfaced manner on the atmosphere side and/or the tin bath side, and at least one fire-protection layer, which is arranged in a surfaced manner on the protective layer. The protective layer is a multi-layer layer structure and includes a first sub-protective-layer of metal-doped silicon nitride, and a second sub-protective-layer of a tin/zinc oxide or a doped tin/zinc oxide.

A sheet material with an anti-skid surface, suitable for use as a roofing underlayment or wrapper, comprises a scrim made of woven plastic tapes with monofilaments that are round in cross-section and have a diameter larger than the thickness of the plastic tapes interwoven with the tapes. The monofilaments form ridges on the sheet material that impart an enhanced coefficient of friction to it. The monofilaments may be incorporated in the weave in the warp or weft directions or both.

Disclosed is a fire protection layer composite for use as preventive fire protection material, and to a method for producing a fire protection layer composite. The invention relates to non-flammable and fire-retardant materials, in particular film composites which are intumescent in the event of a fire. The fire protection layer composite comprises at least one plastics layer, which surrounds a transparent fire protection layer, wherein the fire protection layer comprises an intumescent material. The fire protection layer composite makes it possible to achieve effective fire protection in a compact design. The fire protection layer composite does not produce soot or release toxic flue gases, even under the influence of very high temperatures. This prevents danger to the health of a user of the fire protection layer composite in the event of a fire.

Fire resistant glazings having improved properties comprising a silicate based interlayer which contains from 35% to 43% by weight of water may be produced using a cast in place process. The amount of water in the interlayer is reduced by concentrating the silicate solution or by introducing silica in the form of a silica sol. Preferably a mixture of an aqueous sol and an organosol is used. Polyhydroxy compounds and saccharides may be incorporated into the interlayer to improve the properties thereof and to reduce the water content. The silicate based formulations are pourable and can be used in a cast in place production process and subsequently cured to form an optically clear interlayer.

Provided are an active and passive integrated fireproof heat-insulating board and a preparation method thereof, including: n passive fireproof layers and n or n+1 active fireproof layers, the passive fireproof layers and the active fireproof layers are overlapped with each other into a whole. Each passive fireproof layer includes an inorganic fiber felt and an aerogel; the aerogel is obtained by curing an aerogel stock solution having adhesiveness, and the aerogel stock solution includes, in parts by mass, 1000 to 4000 parts of silica sol, 50 to 150 parts of soluble silicate, 10 to 50 parts of a phosphate adhesive, 5 to 20 parts of quicklime, 5 to 50 parts of titanium dioxide, 10 to 50 parts of calcium stearate, 5 to 50 parts of a hydrophobic modifier, 5 to 50 parts of an acid-base regulator, and 1000 to 4000 parts of a solvent.
