Abstract
The invention relates to a nailing flange blanket, comprising a substantially flat carrier of flexible material and a layer of mineral wool which is adhered to the carrier, wherein the carrier extends on either side of the layer of mineral wool and wherein the carrier comprises a layer of aluminium foil, wherein the carrier comprises a layer of plastic imparting strength to the carrier.

The greater strength of the plastic plays a part here; it is possible to suffice with a thinner layer of plastic.
Description
NAILING FLANGE BLANKET
The invention relates to a nailing flange blanket, comprising a substantially flat carrier of flexible material and a layer of mineral wool which is adhered to the carrier, wherein the carrier extends on either side s of the layer of mineral wool, and wherein the carrier comprises a layer of aluminium foil.
Such a nailing flange blanket is known from NL-A-1002950.
In this prior art nailing flange blanket the outer 0 layer of the carrier, i.e. the layer of the carrier which is located on the side remote from the layer of mineral wool, is manufactured from paper, such as kraft paper.
Paper is a flammable material with a high calorific value. s The object of the present invention is to provide such a nailing flange blanket which is less flammable.
This objective is achieved with such a nailing flange blanket wherein the carrier comprises a layer of plastic, o Plastic is a material which is less flammable than paper.
The calorific value of a plastic layer is - surprisingly - smaller than the calorific value of a paper layer of the same strength. The greater strength of 2s the plastic plays a part here; it is possible to suffice with a thinner layer of plastic.
Paper otherwise ignites more readily than plastic; paper ignites quickly, while plastic must melt and evaporate before fire occurs, so The plastic layer preferably extends on the same side of the carrier as the layer of mineral wool . Optimum use is hereby made of the moisture- inhibiting action of the aluminium foil . This foil is
situated as far as possible on the outside of the blanke .
Experiments by applicant have further demonstrated that polyester is a material which is very suitable for s these applications.
The material is strong and the fire load is relatively low.
According to a further embodiment the layer of polyester has a thickness of between 25 gr/m2 and o 60 gr/m2. This is a thickness at which sufficient strength is obtained, while the fire load and the costs are minimal .
According to yet another preferred embodiment there is applied between the layer of aluminium foil and the s layer of polyester an adhesive connecting the two layers . Although it is possible in principle to melt polyester directly onto the aluminium foil, this results in a significant weakening of the tensile strength of the polyester during the adhesion process. This causes the o danger of folds occurring in the formed carrier.
This is avoided by applying a separate adhesive. Polyethylene has a good adhesive properties and has a melting point which is lower than the melting point of polyester. This makes it a suitable material as adhesive. 5 The polyester can then be adhered to the aluminium without melting or weakening.
According to yet another preferred embodiment the layer of mineral wool is adhered by the same adhesive, thus preferably polyester, to the carrier. so This results in a considerable simplification of the production process.
An even greater reduction in cost is obtained when the thickness of the layer of aluminium foil lies between 5 and 10 μm. 35 This is of course a very thin layer, but in combination with the layer of plastic a carrier is obtained with sufficient strength and vapour-tightness. According to yet another preferred embodiment the nailing
flange blanket is provided with a cover layer which extends over the layer of mineral wool and which is connected to the carrier on strips of the carrier extending on either side of the mineral wool layer. As already known from the above mentioned
NL-A-1002950, it is attractive to provide the layer of mineral wool with an envelope so as to prevent contamination of the environment as a result of particles being released from the mineral wool, for instance during transport and storage. These can after all cause skin irritation.
A particular embodiment of the invention provides the measure that the nailing flange blanket is provided with a cover layer which extends over the layer of mineral wool and which is connected to the carrier on the edges extending on either side of the layer of mineral wool .
In the prior art use is made herein of paper although, as the inventors of the present patent application have found, it has likewise been found possible to make use of plastic as covering layer for the carrier.
The attachment of this envelope to the edges is preferably achieved with the same adhesive; the same 5 adhesive can hereby be applied on two different materials in one process run.
The present invention will be elucidated hereinbelow with reference to the annexed figure, which shows a schematic perspective cross-sectional view of a nailing o flange blanket according to the present invention.
The figure shows a nailing flange blanket 1. This latter is formed by a carrier 2 and a layer of mineral wool 3 present thereon.
The carrier is formed in the present case by an 5 outer layer 4 of aluminium foil, an adhesive layer 5 of for instance polythene and a plastic layer 6 of for instance polyester. Applied once again to the top of layer 6 is an adhesive layer 7, which is preferably also
manufactured from LDPE. Adhesive layer 7 serves to adhere the layer of mineral wool 3 to the carrier.
The construction described up to this point can readily be used per se as nailing flange blanket and herein displays the advantages of the present invention. It will be apparent that carrier 2 extends on either side of the mineral wool in the form of strips 8, 9. Use can be made of reinforcing wires 10, such as are per se known from NL-A-1002950, in order to reinforce these strips .
The construction can herein be used as shown in the figure, wherein adhesive layer 7 extends below the reinforcing wires, but it is likewise possible for adhesive layer 7 to extend over reinforcing wires 10, as is otherwise also described in the stated Netherlands patent application.
This latter option in particular is attractive when an envelope 11 is arranged around the layer of mineral wool 3 as shown in the figure. This drawing shows that envelope 11 is formed by four layers: polyester 12 on the outside, thereunder an adhesive layer 13 of polythene, a layer 14 of aluminium foil and, wholly on the inside, a layer 15 of adhesive material. This latter layer in particular provides the option of adhering the envelope to the layer of mineral wool, which enhances the strength of the construction.
Instead of the assembly of four layers shown here, it is of course possible to make use of a simple assembly, for instance of only one layer of polyethylene. Use can be made in all cases of adhesive layer 7 to adhere the envelope layer to the carrier at the position of the two side strips 8, 9 .
It is noted here that it is attractive in the production of such a blanket to initially connect the reinforcing wires to those parts of the cover layer which are subsequently connected to the strips. This advantage is particularly important when the cover layer is formed by a single material. The adhesion of the reinforcing
wires to the cover layer results in a heating which does not result in a deformation in the case of the single material; when the carrier is heated there is the danger of the already present adhesive material melting and the whole blanket disintegrating. This danger is avoided by initially performing the adhesion with the cover layer. The subsequent connection to the carrier can easily be performed locally, for instance by heated wheels, so that melting of the adhesive elsewhere is avoided. An additional advantage of the use of plastic in the carrier is the improvement in the sound-insulating properties .
