Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT 4 t t Applicant(s): Invention Title: ISOVER SAINT-GOBAIN INSULATING ROOF PANEL, PROCE6S AND DE&VICE FOR THE MANUFACTURE THEREOF.
The following statement is a full description of this invention, including the best method of performing it known to me/us: R 2 INSULATING ROOF PANEL, PROCESS AND DEVICE FOR THE MANUFACTURE THEREOF The invention relates to insulating roof panels and in particular to panels intended to solve the problem of sealing support insulation for flat or slightly inclined roofs, with metal, wood or concrete frameworks.
These panels are formed of a felt or mat of mineral wool, of rock or glass, and of a ve\ covering for example a shet \of glass impregnated with bitumen, the covering being intended to receive at least one layer of a sealing material.
Panels of this type are described in published patent EP-A-0 109 879 for example, which relates in particular to a rigid panel of highdensity mineral wool, covered with a sheet of glass impregnated with bitumen on two sides, and I of a surface film. In this type of panel, the Sadhesion between the covering and the mineral wool mat is obtained by the bitumen impregnating the sheet.
These panels are secured directly to the ground or the framework of the roof, generally by means of adhesion if the surface to be covered i i J 3 flat, or by mechanical securing devices, in particular with screws and washers, if it is to be secured to a metal or wooden framework.
The panels are then covered with at least one sealing layer, generally a bituminous covering which can be adhered using bitumen or welded by heating with a flame.
These panels, and the mounting thereof, generally give complete satisfaction when they are used to insulate the roofs of buildings situated in areas with very varied climates, even those that are subject to violent storms, provided that the mounting instructions are always followed.
Moving about continuously on the mounted panels before they are provided with the sealing layer or i layers is not permitted, in particular in cases where this mounting uses metal securing means.
It appears that failure to respect these instructions may render the coverings subject to deterioration in very violent storms. The phenomena of partial tearing of the covering has thus been observed. j i The invention proposes an insulating panel which renders the rel' ability of the cover i\ 1 4 less dependent on scrupulous adhesion to the mounting instructions.
The invention proposes an insulating panel having reinforced adhesion between the mineral wool mat and the sealing support covering, obtaining, in particular, improving resistance to tearing or to stripping of the roofing in the case of violent storms.
According to the present invention there is provided insulating panel for insulating substantially horizontal or slightly inclined roofs, comprising a mineral wool felt and a sealing support covering, adhered using an adhesive to one surface of the felt, in which the surface of the felt onto which the sealing support covering is adhered has recesses distributed over the entire surface thereof and forming anchorage points for the adhesive.
The recesses according to the invention must be a a. sufficiently large in section and depth to provide satisfactory anchorage, i.e. which is resistant to the various shearing forces. In effect, the Applicants noted 20 that the tearing of the cover in the case of a violent storm is (lue, in particular, to the adhesion between the covering and the mat being weakened during the production of the insulation, owing to the shearing forces to which the panel is subjected when the person applying the 2? insulation walks on ti K 1 it, which is generally the case when insulation is being applied.
However, the recesses must not be too large, in particular in relation to the thickness of the mat, in order not to create mechanical weak points in the panel, or even in order to avoid a loss of insulation properties. Thus, according to an advantageous feature of the invention, the recesses have a depth of between 5 and 10 mm.
The shape of the recesses in section may be very varied and may be squares, rectangles, t circles or other geometrical shapes permitting thvf attachment of the adhesive and thus of the covering.
The recesses may advantageously be I produced by punching the panel. The shapes of the recesses thus obviously depend on the shape of the punching dies.
Other than the shape of each recess, the arrangement of the recesses in relation to one another Is a feature of the panel according to the invention. io 6 The recesses may thus be disposed along lines of very varied shapes. However, the use of arrangements which may weaken the mechanical properties of the panels must be avoided. To this end, it is preferable to avoid an arrangement of the recess along a straight line parallel to the short side of the panel.
i Conversely, an arrangement in a helical shape proves advantageous.
r 4 The sectional surface of the recesses is, like the depth thereof, preferably within a given I ,range, as a function of the adhesion forces desired and of the adhesive used, the latter ,preferably being bitumen, as in the case of known ,panels and for the same reasons for which it was selected: reduced costs, ease of application, S, compatibility with the sealing covering etc. The surface of the recesses is thus advantageously between 0.2 and 2 cm.
d Therefore the ratio d/s of the depth to the surface (s) of the recesse expressed in unit mm/mm 2 is generally below 0.3 unit and preferably below or equal to 0.1 unit.
According to a feature of the invention, the ratio of the surface of the recesses to the K total surface of the panel is between 0.05 and 0.15.

7 The covering of the panel may consist of a foil or of a shee* preferably a glass sheet, impregnated with bitumen or with another adhesive which can be accommodated in the recesses or securing points provided on the mineral wool mat.
The covering may cover two edges of the panel and comprises, in addition to the sheet-of glass, a thermofusible film such as that described in the above-mentioned document EP-A-0 109 879.
The invention also relates to a method and a device for the continuous production of the insulating panels described hereinabove.
According to the method, a high-density rigid mineral fibre insulating mat is produced continuously by the conventional methods for rock wool or glass wool, recesses being subsequently formed, advantageously by punching, on the surface intended to receive the adhesive covering, in order to form anchorage points regularly spaced over the surface for the adhesive used for adhering the covering, the adhesive and the covering being applied subsequently to the surface provided with the recesses.

8 One of the advantages of punching in relation to other methods of forming the recesses is the simplicity with which it can be carried out. A further advantage is that it is free of dust in comparison to machining of the mat.
In a preferred method, the adhesive is applied to the mat at the same time as the ti",i covering. This is in particular the case if the covering uses bitumen as an adhesive and if it is impregnated therewith prior to its application to the mat.
Advantageously, the covering, which is continuously applied, has a width corresponding to the width of the mat increased by slightly less than two times the thickness thereof, which permits a partial covering of the two sides of the panel.
The covering may advantageously comprise a so-called "separating" sheet of plastics material as in the case of the panel described in EP-A-0 010 879 mentioned above, the description of which is incorporated here by means of this reference.
I~ ,i 9 The invention also relates to a device for performing the method and producing the insulating panel.
The device comprises the known production means for producing the insulating panel, ie. a fibre-drawing device incorporating the binder at the fibre-drawing point, a conveyor receiving the Sfibres, means conferring the desired thickness on the mat, and an oven for polymerising the binder means for applying the covering and for its adhesion to the lower surface of the panel, and cutting means. According to the invention, the device further comprises a system located between the oven for polymerising the binder and the covering adhesion station, which comprises an embossing roller rotating about its axis at the velocity of the production line, supporting projecting bosses or punching dies distributed over its periphery, and at the base thereof, below the transporter, means enabling a constant pressure to be applied to the felt of mineral wool felt in order to maintain it in contact with the embossing roller, these means advantageously being a pressing roller rotating about its axis.
In one embodiment of the device, the embossing roller rotates freely about its axis while the pressing roller is driven at the velocity of the production line.
In a variant, the embossing roller may be driven.
Means for adjusting the height of the rollers enable the penetration of the punch dies into the mineral wool to be varied according to r 1 the desired depth for the recesses thus created, which, as indicated above, may advantageously be between 5 and 10 mm.
Further advantages and features of the invention will appear in the following description given with reference to the Figures, in which.
Figure 1: shows a panel according to the invention; Figure 2: shows a schematic view of part of the device for producing the panel.
The panel I shown in Figure 1 is formed of a rock wool felt 2 of which the binder content is 5 weight It has a density of 160 kg/m' and a thickness of 80 mm. The upper surface 3 thereof has recesses 4 obtained by punching and disposed along lines 5 which are not parallel to the short i side of the panel, each of these lines being frustoconical with a rectangular section at the base which has a surface area of approximately 100 Mnm2 and a depth of approximately 10 mO (ratio d/s 0.1).
On ,this surface 3 a composite covering 6, formed of a of glass 7 impregnated with bitumen 8, and of a thermoplastic film 9, is adhered, the covering being applied directly after the impregnation of the sheet with bitumen in order that this adhesive can penetrate the recesses 0 provided on the surface 3 of the felt and thus form anchorage points for the covering, thus improving the adhesion between the covering and Sthe felt.
c This insulating panel may be used to insulate flat or slightly inclined roofs.
When a horizontal roof having a metal framework and formed of profiled sections is to be insulated, the panels are mechanically secured onto the profiled sections using screws and washers, the covering obviously being directed towards the exterior.
In order to complete the sealing, the A secured panels are co&ted on site with a sealing Scovering.

A suitable glass sheet may be based on fibres of insulating glass or on so-called textile fibres, obtained either by the dry or by the wet method. This sheet may be reinforced by longitudinal reinforcing glass threads.
The c9vering may also be a composite formed of a shee\\of glass and of a grid reinforcing the resistance of the sheet to tearing, the assembly being impregnated with bitumen.
The insulating panel according to the invention has very good resistance when it is walked upon, the adhesion of the felt and the covering in particular remaining high compared to an insulating panel that has the same composition, but without anchorage points.
In Figure 2 a device for punching the panels is shown. This device is placed between the oven (not shown), in which the felt, in the form of a continuous strip, is hardened by polymerisation of the adhesive, and the station 0oo 9 9 Soo oo oo *O 0 00 9 wig

The two jacks are mounted in an articulated manner about the axes 36, 37 supported by the supporting member 29.
In the operating position, the pressing roller 18 is applied on 'the felt 10, forcing it to be subjected to punching by the roller 14.

Downstream of the embossing roller, the device comprises a roller 38 permitting the application of the covering 39 impregnated with bitumen 41 on the lower, surface 40 of the felt which lower surface has just been punched.
The anchorage according to the invention of the covering which will be later, on site, coated with a sealing covering, which is made on the line secure the reliability of the insulation system, contrary to an anchorage of the sealing covering directly on site as described in US-A-4 766 024.
