Definitions

  • the present invention relates to an insulation element for fitting between elongated members in a framework of a building structure, such as between rafters, beams or the like, said insulation element having a substantially rectangular shape with substantially parallel first and second sides and substantially parallel third and fourth sides, exhibiting a first side portion and a substantially parallel opposing second side portion.
  • Building structures typically comprise a framework with a number of elongated members, such as rafters, joists etc, defining a number of cavities with the elongated members of the framework as cavity walls.
  • a roof structure comprises a number of rafters with a certain distance apart. It is typically required that a roof or a floor structure must be insulated and therefore insulation panels are fitted in these cavities.
  • fibrous insulation material is often used. Such fibrous insulation materials, such as glass wool, stone wool or other fibrous material panels, may be provided in rectangular building elements or as a roll.
  • the distance between the elongated members of the framework in a building structure may vary from one structure to another or even within the same building structure. In roof structures the distance may vary from e.g. 550-950 mm.
  • the insulation material is somewhat flexible there are limitations as to how compressible the insulation elements can be subjected to before the compressed element may bend out of the cavity if the insulation element is too compressed when fitted between the rafters and beams. Therefore, insulation elements of the initially mentioned kind must be manufactured in many different sizes in order to ensure a correct fit.
  • An advantage with this kind of fibrous insulation slab product is that it can be cut into an appropriate size and is easy install and easy for the inexperienced builder, such as the DIY builder, to understand and makes it easy to fit a suitable insulation to a building structure, such as a roof a wall or a floor structure.
  • an object of the present invention is to provide an insulation element that allows for a broader range of use making it more attractive to building material retailers as well as their customers.
  • an insulation element of the initially mentioned kind wherein at least said first side portion is provided with a trim portion with a elongated trim section along the first side, said trim section having a predetermined width; and at least said second side portion is provided with a flexible zone extending along the second side comprising a flexible section with a predetermined width in the insulation element.
  • the insulation element according to the invention may be made of any insulating material. Often a fibrous insulation material is preferred. Especially mineral wool, such as stone wool or glass wool is preferred.
  • An insulation element according to the invention is suitable for fitting within a wide range in the distance between elongated members in a building framework.
  • An insulation element according to the invention is cost effective in production, whereby a low-priced fibrous insulation element for a wide range of use in building structures may be achieved.
  • the flexible zone along the section side is made less rigid during the manufacture, e.g. by pressing rollers into the zone and moving them along the edge.
  • This has the advantage that this zone is compressible and may be compressed in order to fit between the rafters and beams of the building structure, e.g. two rafters or the like. If the compression of the second side is not sufficient for obtaining a good fitting of the insulation element, i.e. if the distance between the cavity walls is smaller, the trim portion on the side opposite the flexible portion of the rectangular insulation slab may be cut off whereby the width of the insulation element is reduced.
  • the need for trimming the insulation element by cutting off the trim section becomes easily visible.
  • trim zone extends beyond the second rafter, i.e. the transition between the trim zone and the rest of the insulation element is positioned above the rafter.
  • This transition may be marked with a cutting line marking the trim portion and making it easy for the builder to cut away the trim portion and fit the insulation slab. With the pre-cut cutting line, the trim portion will have a regular shape when cut away which makes it suitable for reuse e.g. to fit into small cavities the building structure.
  • the advantage of an insulation element according to the invention the need for different formats is significantly reduced in order to cover the varying framework distances involved in building insulation.
  • the third side of the insulation element may be provided with a trim portion extending along the third side and the fourth side of the rectangular insulation element may be provided with a flexible zone comprising a flexible section extending along the fourth side.
  • the insulation element is provided with flex/trim capability in both orientations, This means that the range of use is doubled for one format.
  • trim section width is substantially equal to the flexible section width and wherein the first and second sides are provided with a length substantially equal to the sum of the width of the flexible zone, the width of the trim zone and the length of the third and fourth sides.
  • the at least one flexible zone is provided by softening the respective side by compressing the edge during manufacture and thereby reducing the fibre bonding in the flexible section.
  • the fibre bondings are broken making the fibrous insulation element for flexible without reducing the density and without significantly influencing the thermal insulation properties.
  • the at least one trim portion is provided by a cutting line parallel to the trim side, i.e. the first - respectively third - side.
  • this cutting line may be a visual line marker.
  • said cutting line is a pre-cut slit having a depth less than the thickness of the panel, preferably at least 50 mm and wherein said slit being substantially parallel to the trim side, i.e. the first - respectively third - side.
  • the insulation element is a mineral fibre batt.
  • the present invention also relates to other types of fibrous insulation materials.
  • the insulation element is provided with a density of 25-45 kg/m 2 , preferably 28-35 kg/m 2 .
  • the insulation element is provided with a thickness between 100 and 400 mm, more preferably approx. 140 mm, 160 mm, 180 mm or 200 mm.
  • the insulation element is provided with a first top layer having a first density and a second layer having a second density, said first density preferably being larger than the second density,
  • first density preferably being larger than the second density
  • Figure 1 shows a first embodiment of an insulation element 1, is having a rectangular shape with first and second sides having a length l and third and fourth sides with a width d.
  • the opposing first and second sides are provided with a trim portion 3 and a flexible portion 4, respectively.
  • the trim portion 3 is separated from the rest of the insulation element 1 by a cutting line 7.
  • the width of the trim portion is d l and the width of the flexible portion is d f .
  • FIG 1 the most basic embodiment of an insulation element according to the invention is shown.
  • a second embodiment is shown, where a second trim portion 5 is also provided along the third side and a flexible portion 6 is also provided along the fourth side.
  • the cutting lines 7, 8 may be printed lines on the top surface of the insulation panel 1 or - as shown in fig. 3 - pre-cuts 7, 8 partially separating the trim portions 3, 5 from the rest of insulation panel 1.
  • These pre-cuts have a depth, which is less than the thickness t of the insulation panel 1, varies depending on the thickness t of the insulation slab, but is preferably at least 50 mm and more preferably 50 mm less than the thickness t, Often the depth of the pre-cut will be in the range from one third to two thirds of the total thickness t .
  • the thickness t may be within the range of 100 - 400 mm.
  • the insulation elements 1 are manufactured in standard sizes and thicknesses, e.g. with a thickness of 140 mm, 160 mm, 180 mm or 200 mm.
  • the insulation slab 1 is to be fitted between two rafters or similar elongated framework members 2 in a building structure with a mutual distance D between them. This may be rafters in a roof structure, a wall structure or a floor structure where thermal and/or acoustic insulation is required.
  • the insulation slab 1 is placed with the flex zone 4 abutting one or the rafters 2 so that the flexible zone is not compressed but merely positioned abutting the first rafter 2.
  • the width d (see fig. 1 or 3) of the insulation slab 1 is larger than the distance D between the rafters 2.
  • the insulation panel width d is such that the cutting line 7 is placed above the rafter 2 as it is the case in fig. 4, the trim portion 3 is to be cut off and the worker can easily cut along the cutting line 7 with the rafter 2 serving as a backing board for the cutting action in the insulation slab 1.
  • the resulting insulation element 1 may then be fitted by compressing the flexible portion without providing too much compression causing the insulation element to buckle or bend out of the cavity between the two rafters.
  • the insulation element 1 may be fitted in the same manner without having to trim the width first.
  • the distances D between the elongated members 2 in the frameworks is determining which insulation element width is to be used.
  • In fig. 6 are shown eight typical distance ranges that must be covered in order to provide an insulation element product range that covers the insulation needs for small building projects, such as DIY projects, comprehensively.
  • the insulation element shown in fig. 7 is provided with trim portions 3, 5 along its first and third sides and flexible portions 4, 6 along its second and fourth sides.
  • this format is adapted to fit four different distances D 1 - D 4 covering the lower part of the range. If the distance D between the rafters is between 550 - 650 mm, i.e. D 1 or D 2 , the insulation element is fitted with its longitudinal orientation parallel to the rafters. If the rafter distance is within the D 1 range, the trim portion 3 along the first side is cut off and thereby reducing the width to 610 mm and then compressing in particular the flexible zone for fitting the insulation between the rafters. If the distance is within the D 2 range, the trim portion should not be cut off, as the insulation element fits between the rafters with its longitudinal orientation substantially parallel to the rafters,
  • the distance between the rafters is within the range of D 3 or D 4 , i.e. between 650-750 mm
  • the advantage with an insulation element according to the preferred embodiment of the invention as shown in fig. 2 and fig. 3 becomes apparent.
  • the insulation element 1 is oriented with its longitudinal orientation substantially perpendicular to the rafters and the second trim portion 5 may be cut off if the distance is within the D 3 range.
  • a second "large” format is shown which similarly covers the rafter distance range of 750-950 mm, i.e. D 5 to D 8 .
  • This "large” format insulation panel is provided with a length l of 960 mm and a width d of 860 mm. Again this insulation element may be oriented with its longitudinal orientation parallel to the rafters or perpendicular to the rafters depending on the distance D.
  • the trim portions and the flexible portions are provided with the widths d f and d t of approx. 50 mm,
  • This system in use is easy to illustrate and to instruct a user of how to trim and install.
  • Information about rafter distances could advantageously be printed on the top of insulation element so that the user can easily find instructions on the product during the insulation fitting operation.
  • the fibrous insulation panels are produced by cutting up a fibrous material web of e.g. stone wool. This web is often produced with a width of 2000 mm and by providing the "small" format with a width of 660 mm, three adjacent lines of insulation panels may be cut from this material web leaving a minimum amount of fibrous waste material.
  • the "large” format may be produced in two adjacent lines each with a width of 960 mm, which is the length of the longitudinal direction of the "large” format panel. This also minimises the amount of waste material.
