Definitions

• the invention relates to a thermal and acoustic insulation panel intended in particular for the insulation of dry roofing, or for the constitution of suspended ceilings in particular for industrial buildings or intended for the public such as commercial premises, meeting rooms. shows, etc ...
• Such a panel is normally constituted by a base layer of mineral fibers, for example glass fibers, provided on the visible side with a facing layer which gives it a decorative finished appearance.
• This facing layer is for example a polyvinyl chloride film, a glass fiber veil preferably obtained by the wet method or an aluminum film optionally coated on kraft paper.
• the glass veil facings are clearly superior to those in other materials because they can be painted and match the decor. But these facings in glass veil have the serious drawback of being permeable to air and water vapor.
• the ambient pressure is generally different from that prevailing in the room. Consequently, a gas exchange flow is established through the panel consisting of two porous layers which become real dust filters and the panels are quickly blackened.
• Waterproof facings of the aluminum film type cannot be painted and are therefore more particularly suitable for factory halls where the finish aspect is of less importance. In addition, they reflect at least part of the sound waves which can therefore no longer be absorbed by the base layer of glass fibers. Acoustic insulation is therefore greatly reduced.
• German utility mode DE-U-85 32 239 describes a thermal insulation panel consisting of an insulating layer and a facing layer of glass fleece. Between these two layers is optionally inserted an aluminum foil acting as a vapor barrier.
• the essentially vertical arrangement of the fibers constituting the insulating layer and on the other hand the need to obtain the vapor barrier effect with a thickness of the aluminum sheet of more than 12 microns, adversely affects any acoustic character. Indeed, any aluminum sheet with a thickness greater than 9 microns will reflect sound waves therefore preventing their absorption by the porous insulating layer of mineral fibers.
• FR-A-2 443 925 an insulating panel comprising a skin plate impermeable to water vapor made of a metallic sheet sandwiched between two sheets of nonwoven glass to which the metallic sheet is glued with an adhesive film.
• the nonwoven sheets provide a bonding base for effective bonding to the insulating core.
• the present invention relates to a thermal and acoustic insulation panel which combines good aesthetic quality with good thermal and acoustic insulation performance and simplified maintenance.
• a thermal and acoustic insulation panel comprising an insulating layer of mineral fibers, in particular glass fibers bonded by a synthetic resin, a surfacing layer constituted by a glass fiber veil, a heat-bonding polyethylene film reactivable to the heat of a grammage less than 40g / m2, an aluminum film with a thickness less than or equal to 9 microns, bonded to a facing layer constituted by a glass fiber veil.
• the outer layer of such a panel consists of a veil of glass fibers, preferably obtained by the wet method, according to a technique analogous to the techniques of papermaking, from glass fibers drawn continuously, then cut ( so-called textile fibers).
• a veil of glass fibers can be dyed with the chosen colors.
• the insulating layer is formed of mineral fibers produced preferably by centrifugation and drawing by means of gas streams at high temperature and speed. raised in accordance with the fiberizing process described in patent EP 91 866 according to a usual technique for the manufacture of insulating blankets; an organic binder being sprayed directly on the fibers in the fiber hood.
• organic binder any type of resin known in the mineral fiber industry is used, in particular phenolformaldehyde resins modified or not with urea or melamine resins which have improved fire resistance.
• the thickness of the insulating layer is generally between 10 and 100 mm, its grammage between 700 and 2500 g / m2, for glass fibers, which gives very light panels whose dimensions (for example 600 x 1200 mm ) allow a simple and fast installation.
• a fusible film with low air permeability and especially to water vapor and an aluminum film are combined according to the invention. with a thickness less than or equal to 9 microns, glued to the facing layer.
• the aluminum film ensures less permeability to water vapor from the panel.
• the thickness of the aluminum film must be limited to a maximum of 9 microns otherwise the panel loses all sound insulation quality, the aluminum foil reflecting the sound waves.
• the sealing of an aluminum foil against water vapor can only be considered sufficient insofar as its thickness exceeds 12 microns.
• this fusible film makes it possible to obtain a bonding surface which has a greatly weakened permeability compared to that obtained with dots of adhesive.
• this fusible film is coated directly on a complex painted decorative glue - glue - aluminum.
• the activation of the fusible film is obtained by means of a heating table or any other equivalent means.
• This fusible film is for example a polyethylene film with a grammage of less than 40 g / m2 which is sufficient to obtain a solid bond.
• An iron-on film of such a small thickness is not itself perfectly impermeable, however by combining with the aluminum film, an extended barrier is obtained which is sufficiently impermeable.
• the solidity of the bond between the fusible film and the insulating layer of mineral fibers, in particular glass fibers, is all the better as the surface of the insulating layer is smooth. This smooth character can be obtained at the stage of obtaining the insulating blanket.
• a surfacing layer preferably formed by a veil of glass fibers - for example of textile glass fibers - on which the insulating glass fibers are directly collected at the time of manufacture.
• insulating mattress the final connection between this surfacing veil and the layer of insulating fibers is thus produced by means of the resin bonding the fibers together.
• the surfacing veil is preferably obtained according to a papermaking technique which gives it a fairly constant thickness over its entire surface. In addition, it improves the mechanical strength of the panel which is stiffened without the need to increase its density and therefore its weight.
• a first layer of paint is uniformly deposited, for example 50 g / m2 which serves as a background dye, then by means of printing rollers a second layer, possibly in another color, which provides a pattern of decor.
• the base dye layer serves as a mask and removes the shiny appearance and reflections from the aluminized layer placed behind the porous veil which is therefore partially transparent.
• the panel according to the invention does not become very dusty, constitutes a barrier to sufficient water vapor so that the panel can be used as a false ceiling even under the last level of a building, without the risk of condensation, and while ensuring quality acoustic and thermal insulation.
