• SE-C2-507549 discloses a fastening element and a method of fastening such insulating units to each other.
• This fastening element is in the form of a helix shaped screw composed of a helix formed head and a helix formed wire. The helix shaped screw is screwed into the insulating materials to be joined together. The joint provided by use of this helix shaped screw is generally acceptable.
• the objective of the invention is thus to provide a method of joining two or more units of insulating material to each other which method does not have the drawbacks of the known methods as disclosed above.
• the invention comprises the use of a fastener for joining two or more units of insulating material to each other.
• the fastener for use according to the invention comprises a head and a body extending from its head.
• the body has an elongated shape comprising a first section and a second section, wherein this first section is connected to the head.
• the head may also be made of the same material as that of the first section and may be shaped in direct prolongation of the first section of the body.
• a first horizontal plane is defined as the plane perpendicular to the extending direction of the first section of the body and containing the point of connection between the head and the body.

• the head of the fastener extends beyond the first horizontal plane as defined above.
• the head should preferably be in the form of a 0.5-10 mm thick disc arranged in said first horizontal plane. If the head is not arranged in the first horizontal plane, the head may protrude out of the connected insulation material units, and such protrusion is in general undesired.
• the periphery of the disk may have any size and shape, provided that the head is sufficiently large to act as a hook and prevent the head from penetrating through the insulating unit.
• the head should be in the form of a disk with a periphery surrounding an area of at least 20 mm 2 , and if the insulating units contain mineral fibres, the area should preferably be at least 100 mm 2 .
• the shape of the head or the periphery is in general not important and may include any rounded shapes, e.g. oval or circular, as well as any angular shapes e.g. triangular, quadrangular, pentagonal, hexagonal, etc.

• the head could also preferably be covered by a capsule in order to minimize/prevent the filtering of the fasteners into each other.
• a capsule in order to minimize/prevent the filtering of the fasteners into each other.
• filtering can also be minimized by letting the spiral close into itself/join itself.
• the length of the body should be specific, selected for the particular use. The thicker the insulating units are, the longer the body should be. In general, the length of the body should be sufficiently long so that the fastener can penetrate at least 0.5, preferably at least 1 cm into the thickness of the outermost insulating unit (the unit farthest from the head of the fastener) , and penetrate the one or more other inner most insulating unit(s) . In most situations it is preferred that the length of the body should be between 10 and 200 mm, more preferably between 20 and 100 mm. The length of the body is defined as the perpendicular distance between the first horizontal plane and a second horizontal plane parallel to the first horizontal plane and containing a tangent to the point of the body farthest from the first horizontal plane.
• the second section is the first section in an angle between 45 and 135 degrees, preferably between 85 and 95 degrees, and more preferably around 90 degrees relative to the first section.
• the second section of the body is connected to a protrusion from the first section of the body to provide an angle as described above between the first and the second section.

Due to providing a fastener which is both cheap and easy to produce it is, however, preferred that the fastener is shaped as a bent nail.
• the body may preferably have an angular or round cross- section i.e. be shaped as an angular or round rod e.g. being oval or circular, as well as any angular shapes e.g. triangular, quadrangular, pentagonal, and hexagonal, which rod preferably has a maximum diameter of between 0.5 and 5 mm.
• the cross-section or the diameter of the body may preferably be substantially equal to the diameter in its first section and more preferably the second section may have a similar diameter throughout its length besides a tip portion, which tip portion comprises a cone-shaped tip.
• the body and head may be made from similar or from distinct materials.
• Preferred materials for both head and body include any metals, preferably steel and brass, and further the preferred materials include polymers, preferably polymers with a relatively high flexural rigidity, e.g. polystyrene, polycarbonate, polypropylene and polyamide.
• the second section of the body may e.g. be coated with an expandable composition i.e. a composition which expands when subjected to heat, moisture, microwave or similar.
• the expandable composition could preferably be glue or paint which expands under influence of heat.
• the method according to the invention of joining two or more units of insulating material to each other comprises the steps of

• the units of insulating material may have any desired size.
• the shape of the units of insulating material may also be as desired, but it is preferred that the surfaces of the units of insulating material which are supposed to face each other in the step of connection have shapes which correspond to each other to provide a tight connection.
• the fastener (s) are turned e.g. at least 5 degrees, preferably at least 45 degrees and most preferably around 90 degrees.
• the number of fasteners used connecting two or more units of insulating material to each other depends on the size of the units and the desired strength of the connection. The skilled person will by use of a few tests be able to find the optimal number of fasteners for a specific connection of units of insulating material.
• the units to be connected are held together in the desired formation and the one or more fasteners are inserted into the units of material to thereby join the units of insulating material together.
• the units of insulating material may be compressed during the fastening of the fasteners.
• Another or additional way to obtain a highly tight fastening is to further add glue between the surfaces to be connected. The amount of glue can be much lower than when using glue alone. Also it is possible to use glue with less tack as the fastener will hold the units of insulating material together.
• the fastener is inserted into and penetrates a first unit and optionally further units of insulating material designated as the innermost unit(s) of insulating material, and therefrom further inserted partly into an outermost unit of insulating material and finally turned at least 5 degrees.
