Definitions

  • This invention relates to a use of a batt as insulation according to claim 1.
  • a conventional mineral fibre batt comprises a bonded mineral fibre network bonded by a cured bonding agent.
  • Batts having different stiffness at different levels through the thickness of the batt can be made by laminating, with intermeshing at the lamination face, preformed cured batts having different stiffness. Usually it is better to make the batt by curing a mineral fibre web containing uncured bonding agent and which has variable fibre density through the depth or variable binder concentration through the depth.
  • the web may be made by, for instance, centrifugal fiberisation of a mineral melt of glass, rock, stone or slag, for instance using one or more cascade spinners or one or more spinning cups.
  • the production of a cured batt having varying binder concentration through the depth may be achieved as described in EP-A-374112 .
  • the production of a batt by curing a web having higher fibre density in one layer than the rest may be achieved by conventional dual density processes. In these the mineral fibres and bonding agent are collected as a web, the upper layer of the web is separated and consolidated and rejoined on to the remainder of the web, and the web is then subjected to curing.
  • the batt is made notably stiff even when the amount of bonding agent is as low as is reasonably satisfactory to achieve minimum coherence of the batt.
  • this stiffness is highly desirable. However there are some instances when the stiffness created by low binder amounts is undesirable and there are other cases where it would be desirable to provide a surface layer of lower stiffness in a product which has high binder amounts and/or high density and so is, overall, very stiff.
  • a mineral fibre batt disclosed herein has first and second major surfaces and comprises a bonded mineral fibre network which is bonded by a cured bonding agent and which has an inner portion and an outer portion wherein the second surface of the batt is provided by the outer surface of the outer portion, and wherein the outer portion has a depth of at least 5mm and has reduced stiffness due to post-cure compression of the bonded network in the outer portion.
  • the inner portion adjacent the outer portion has the same fibre content type (e.g., average dimensions and chemical type) and distribution, and the same bonding agent and amount, as the outer portion, in which event it is meaningful simply to compare the stiffness of the outer portion with the stiffness of the adjacent inner portion.
  • the adjacent inner portion exhibits also some additional difference, e.g., in fibre content or binder.
  • the invention is a use of a batt as insulation according to claim 1.
  • the bonding agent is usually a conventional bonding agent for mineral fibre batts, for instance a phenolic or other curable thermosetting resin.
  • a product is formed in which the outer portion is less stiff than the inner portion. This presumably is due to fracturing of the bonded network in the outer portion as a result of the compression after curing the bonding agent.
  • the height compression is applied predominantly from the second face by passing the bonded and cured batt through a nip between a surface which supports the first face and compression means for temporarily compressing the batt at the second face. This will result in fracturing the bonded network in the bonded outer portion of the second face, leaving the bonded network closer to the first layer substantially unchanged.
  • the preferred compression means comprise at least one compression-applying roller having a diameter less than the total thickness of the batt and which defines a nip which has a depth of 20 to 90% of the thickness of the batt after curing (giving 10 to 80% temporary height compression).
  • the nip has a depth of at least 30 or 40% of the thickness of the batt and generally not more than 70 or 80% of the height of the batt. For instance it may have a depth of around 55% of the height of the batt, thus giving 45% temporary height compression.
  • the diameter of the or each compression applying roller must be relatively small in order to concentrate the compression forces in the desired region.
  • the diameter is usually less than 75%, and often less than 50%, of the thickness of the batt. It is usually at least 30mm, and is usually below 75mm, often below 40 or 50mm.
  • the support surface is preferably substantially planar but it can be a surface with a large radius of curvature and which thus gives substantially the same support as a planar surface.
  • the support can be a planar plate or conveyor or drum of large diameter, e.g., at least 5 times the thickness of the batt.
  • the compression means comprise a plurality of parallel, compression applying, rollers each having a diameter less than the thickness of the batt (as explained above) and which define with the substantially planar support a nip which decreases in distance as the batt enters the nip, and the final, narrowest, nip preferably is within the range described above.
  • the nip increases in distance as the batt leaves the nip.
  • each roller, in plan view overlaps each adjacent roller and preferably each defines a step of 3 to 15, often 5 to 10mm, up (or down) from the next.
  • the binder content is usually relatively low, for instance 0.2 to 1.5%, often around 0.3 to 1 or 1.2%.
  • the fibre density is usually relatively low, for instance 20 to 100kg/m 3 , often around 30 to 90kg/m 3 .
  • a batt is to be fixed against a non-planar surface, for instance a surface having surface irregularities with a depth of at least 3mm, and often 5 or 10mm or even 15mm.
  • a non-planar surface for instance a surface having surface irregularities with a depth of at least 3mm, and often 5 or 10mm or even 15mm.
  • mineral wool batts against brickwork or other stone walls and these often have an irregular surface.
  • a soft glass fibre panel can be applied to such a surface but this tends to be unsatisfactory since irregularities in the surface are then manifested in the wall, to some extent, in the first surface of the glass fibre panel.
  • any irregular surface on to which a bonded mineral fibre batt is to be secured is normally given a smoothing coat of plaster so as to provide a flat surface against which the batt can be secured firmly. This is wasteful of materials and time.
  • the invention provides a solution to this problem because the batt can now be secured firmly to the irregular surface since the soft outer portion will absorb the irregularities of up to, for instance 15mm, without causing the irregularities to be manifested in the first surface.
  • the batt has a density of 20 to 150, often 50 to 80 or 100, kg/m 3 and a thickness of 20 to 150mm, often 30 to 90mm.
  • It may have a dual density structure, with the outer portion being in the lower density layer for isntance as described in WO88/00265 or a triple layer, for instance as described in WO00/7360 .
  • the batt may have conventional structure and appearance except for the softened rear outer portion, which is typically 10 to 50mm, often 20 to 40mm, deep.
  • the softening can be increased by cutting (for instance to the desired depth of the softened portion) a check or other pattern into the outer portion prior to the mechanical compression.
  • the invention can also be applied to products where the softened portion itself has a relatively high binder content and/or a high fibre density.
  • the softened portion itself has a relatively high binder content and/or a high fibre density.
  • it can have a binder content of above 1%, typically 2 to 6%, for instance 3 to 4 or 5%. It can have a density of above 100kg/m 3 , often at least 160kg/m 3 , up to 180 or even 250kg/m 3 .
  • the mineral fibre network which extends inwardly from the second face has an inner portion and an outer portion wherein the second major face of the batt is provided by the outer face of the outer portion and wherein the outer portion has a depth of at least 5mm and is softer than the inner portion and merges with the inner portion through a transition portion of at least 5mm over which the stiffness increases gradually.
  • the outer portion has a depth of at least 5mm and is softer than the inner portion and merges with the inner portion through a transition portion of at least 5mm over which the stiffness increases gradually.
  • Stiffness for the purposes of this invention can be considered to be modulus of elasticity (EN826), wherein an increasing numerical value for the modulus of elasticity indicates increasing stiffness.
  • the stiffness of the outer portion is less than 90% of what the stiffness would have been if the network had not been fractured and most preferably it is less than 80% or even less than 70% of the stiffness of what the stiffness would have been if the network had not been fractured. It is usually at least 20%, and generally at least 40%, of what the stiffness would have been if the network had not been fractured.
  • the low stiffness, outer, portion generally has a depth of at least 10mm and often at least 10%, and preferably at least 20% or even 30% of the total thickness of the batt.
  • the outer portion can constitute as much as, for instance, 70% or even 80% of the thickness of the batt.
