In addition, the invention concerns a method of producing insulation panels and an apparatus for producing insulation panels according to the method. ## Claims ### Claim 1 A method of producing an insulation panel configured to be fitted between joining profiles in a framework of an insulating building system, wherein the insulation panel is a mineral fiber wool panel, said method comprising the steps of: providing an insulation panel made of mineral fiber wool material with a density in the range of 60 to 100 kg/m3, the insulation panel having substantially parallel first and second main surfaces with substantially parallel, oppositely situated first and second profile contact sides and substantially parallel, oppositely situated third and fourth sides between said main surfaces; providing a groove along the first and second contact sides at a predetermined distance from the first main surface and substantially parallel with said first main surface, whereby said contact sides are divided into a profile abutment portion and a profile covering portion; removing material from the abutment portion of said contact sides so that each profile covering portion extends beyond the abutment portion of the contact side; and manipulating each said extending profile covering portion to provide a flex zone that is softer and more flexible than the remainder of the panel by reducing the fiber bonding in the flex zone, so as to provide a tight panel-to-panel fit and improved thermal insulation when a panel is joined to another panel in said profile covering portion of the first contact side. ### Claim 2 (depends on 1) A method according to claim 1, wherein the steps are carried out substantially at the same time or wherein the steps are carried out sequentially. ### Claim 3 An insulation panel configured to be fitted between joining profiles in a framework of an insulating building system, wherein said insulation panel is a mineral fiber wool panel, said insulation panel comprising: substantially parallel first and second main surfaces having substantially parallel, oppositely situated, first and second profile contact sides and substantially parallel, oppositely situated, third and fourth sides between said main surfaces, wherein said first and second profile contact sides are provided with a groove substantially parallel to the first main surface in a predetermined distance therefrom whereby said first and second profile contact sides are divided into a profile abutment portion and a profile covering portion; wherein the profile covering portion of the side of the insulation panel comprises a flex zone in at least the profile covering portion extending beyond the profile abutment portion whereby said profile covering portion is made softer and more flexible than the remainder of the panel by reducing fiber bonding in the flex zone, so as to provide a tight panel-to-panel fit and improved thermal insulation when it is joined to another panel; and wherein the insulation panel is made of mineral fiber wool material with a density in the range of 60 to 100 kg/m3. ### Claim 4 (depends on 3) An insulation panel according to claim 3, wherein the profile covering portion extends beyond the abutment portion of at least one of the side edges of the insulation panel. ### Claim 5 (depends on 3) An insulation panel according to claim 3, wherein the insulation panel is made of a mineral fibre wool material with a density between 30-150 kg/m3. ### Claim 6 (depends on 3) An insulation panel according to claim 3, wherein the insulation panel is provided with a dual density structure so that the density of the insulation panel between the profile covering portions of the two contact sides is higher than the density of the insulation panel between the profile abutment portions of the two contact sides. ### Claim 7 (depends on 3) An insulation panel according to claim 3, wherein the insulation panel has a compression elasticity modulus of at least 500 kPa, preferably when measured parallel to the width of said insulation panel. ### Claim 8 (depends on 3) An insulation panel according to claim 3, wherein the insulation panel has a total thickness between 75 and 500 mm. ### Claim 9 (depends on 3) An insulation panel according to claim 3, wherein at least the profile abutment portions of the contact sides are provided with an adhesive layer for adhering to the profile. ### Claim 10 (depends on 3) An insulation panel according to claim 3, wherein there is also provided at least one slit in said oppositely situated third and fourth sides for receiving a flange of top and/or bottom frame profiles in the building structure for retention of the insulation panel therein. ### Claim 11 (depends on 3) An insulation panel according to claim 3, wherein each insulation panel consists of one insulation slab. ### Claim 12 (depends on 3) An insulation panel according to claim 3, wherein each insulation panel comprises two or more insulation slabs provided in a stacked and/or layered configuration.
