Abstract: The invention is directed to an anti-vibration sound insulator for a suspended ceiling which is intended to be used either in residential or commercial applications. The insulator comprises a metal furring devised to be fixed to the ceiling. It also includes a central part comprising a star-shaped element having an upper vertical plate provided with an orifice and two lower plates each having extremities. These extremities are folded so as to jointly form a slide rail sized to receive and support the folded extremities of the metal furring. The central part also comprises an insulating element devised to be inserted in the upper plate orifice, this insulating element including an orifice. This latter orifice allows introducing a fixing element so as to fix the insulator beneath a floor, or against a joist supporting the floor.

Abstract: The invention relates to a steam permissive and water non-permissive screen, particularly a sub-roof screen, a rain-proof screen, an air-proof screen or the like. The screen (1) is characterised in that it mainly includes a non-woven fabric made of a mat or a web of a majority of natural fibres (2), preferably vegetable fibres, that has been submitted to a binding operation by pressurised liquid jets, or hydrobinding, and to a hydrophobation process.

Abstract: The thermo-acoustic radiant membrane is designed for use on a floor beneath a spa, whirlpool or therapeutic bath, inertia base or similar. The membrane comprises a radiant layer made of a metallic film, on which a layer of rubber granules of varying size are hot-laminated with a bitumen elastomer to which other components can be added such as wood, mineral, synthetic, or vegetable fibres. The membrane is also provided with a water-impermeable layer to act as a vapour block. Said layer is made from polyethylene, polypropylene, polyester or metal is resistant to tearing, static crushing and tension and has a large capacity for stretching and is covered with bitumen elastomer. The bitumen elastomer layer on the water-impermeable layer is placed on the granule layer of the radiant layer in order to assemble the membrane by adhesion of the layers.

Abstract: The invention relates to a method for making a non-woven mat to be used as a reinforcement for a frame in a flexible sealing membrane. The method is characterised in that it includes providing vegetable-origin natural fibres optionally mixed with a minority of thermoplastic or thermofusible fibres, forming a non-woven mat or web by mechanical, pneumatic or hydraulic batting, submitting the web to two successive consolidation operations including a needle punching operation and a binding operation with a chemical binder or by a thermal processing preferably under pressure, and finally submitting the non-woven consolidated web to a process for the hydrophobation of the fibres.

Abstract: The invention concerns a hot air device for thermowelding membranes to surfaces. It includes an air inlet, a casing in fluid communication therewith, a combustion chamber mounted within the casing and spaced apart therefrom. The chamber has perforations allowing air to flow therein. The perforations allow some air to flow into the upstream section of the chamber producing an air-fuel mixture, and let the remaining air into the downstream section, thus shortening the flame within the chamber and producing hot air. The device includes an outlet portion for expelling hot air and not allowing a flame out therefrom, and a blower to force airflow from the air inlet through the chamber and out from the nozzle. The chamber may be pyramid or cone shaped and have a deflector to help direct air into the upstream section.
