Abstract: A greening device for façades or walls, consisting mainly of a support structure fixed on the façade to be covered and by at least two modules with flat structure and square or rectangular profile, containing a cultivating substrate and including on one of its large surface apparent vegetation elements, the modules being removably mounted on the support structure substantially concealing the latter. The support structure includes at least two spaced apart vertical rails whereon the modules are mounted in vertical rows being located away from the façade or wall and being individually detachable, each module being in the form of a box with globally flat parallelepiped structure of slight thickness compared to its lateral dimensions, the open side of the box opposite the base being closed with an open-work wall. The vertical opposite side walls have catching elements designed to co-operate with reception sites on the mounting rails.

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 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.

Abstract: A process and an installation for the production of a bituminous sealing sheet, comprises a strip impregnated and/or coated with a given bitumen and having a zone in the shape or a band or a portion of a band of a different bitumen from the first bitumen.

Abstract: A process for insulating and sealing roofing comprises coating the substrate (2) with a liquid or viscous composition (3) that is based on modified bitumen or a bitumen/polyurethane mixture by covering rough spots (4) and by filling the hollows or emergent cavities (4′) that are present on the surface of the substrate (2), then applying the insulating layer (1) or individual elements that are intended to form the insulating layer (1) on the coated surface of the substrate (2) before the previously applied coating layer (3) solidifies, whereby the coating layer (3) forms, after drying or polymerization, a water-vapor barrier and an agent for adhesion of insulating layer (1) to the attachment substrate (2), and, finally, applying to insulating layer (1) a sealing coating (6).

Abstract: Resinous monocomponent composition with improved adhesive properties, based on a bitumen/polyurethane prepolymer mixture and adapted to constitute a sealing layer or a portion of a sealing layer, characterized in that the molecules of polyurethane prepolymer comprise at least one segment or group comprising at least 30 atoms of pure hydrogenated carbon.
