Abstract:
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/m 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.
