Abstract
A compressible mineral fibre insulation element (1) having a first major surface (3) opposed to a second major surface (4), and having side surfaces (5) connecting the two major surfaces (3, 4) and defining a thickness of the insulation element (1). The thickness is at least 10 cm. The insulation element comprises a facing (20) provided with at least one extension flange (21) of which the outer end (22) is not secured to the insulation element. The facing (20) is attached to at least a part of the first major surface (3), and the extension flange (21) is prepared for extending over and covering a substantial part of the side surface (5) of the insulation element (1). A method of installing a compressible insulation element is also disclosed.

An insulating product comprising a compressible mineral fibre insulation element (1) having a first major surface (3) opposed to a second major surface (4), and having side surfaces (5) connecting the two major surfaces (3, 4) and defining a thickness of the insulation element (1), said thickness being at least 10 cm, said product comprising a second facing (30) on said second major surface (4) of said insulation element (1) which is provided with flanges (31) extending beyond said second major surface (4), and prepared for being used for attachment of the insulation product;
- characterised in that said product further comprises a first facing (20) which is attached to at least a part of said first major surface (3) and which is provided with at least one extension flange (21) having an outer end and where said outer end (22) is not secured to said insulation element and where the outer surface of said extension flange (21) has a coefficient of friction in relation to a wood surface which is smaller than the coefficient of friction of a side surface of the mineral fibre insulation in relation to the same wood surface.
Insulation product according to any one of the previous claims, wherein the thickness of said insulation element is more than 15 cm, preferably more than 20 cm, and even more preferably at least 30 cm.
Insulation product according to any one of the previous claims, wherein said extension flange (21) is not secured to the side surface (5).
Insulation product according to any one of the previous claims, wherein said facing (20) covers a major part of said first major surface (3) of said insulation element (1).
Insulation product according to any one of the previous claims, wherein said facing (20, 21) is selected from the group:
- paper, fleece, aluminium paper, aluminium foil, plastic film.
Insulation product according to any one of the previous claims, wherein the flanges (21) and (31) are not joined.
Method of installing an insulating product comprising a compressible insulation element (1) between a pair of beams or rafters (2), comprising the steps of:
- providing a compressible mineral fibre insulation element (1) having a first major surface (3) opposed to a second major surface (4), and having side surfaces (5) connecting the two major surfaces (3, 4) and defining a thickness of the insulation element (1), said insulation element comprises a facing (20) having a surface with a coefficient of friction in relation to a wood surface which is smaller than the coefficient of friction of a side surface of the mineral fibre insulation in relation to the same wood surface, and wherein the facing (20) is provided with at least one extension flange (21) of which the outer end (22) is not secured to the insulation element, said facing (20) being attached to at least a part of the first major surface (3) and said extension flange (21) of the facing (20) is prepared for extending over and covering at least a part of the area of at least one side surface (5);
- covering a part of at least one side surface (5) by said extension flange (21) with said outer end being on said side surface (5);
- and
- introducing the insulation element in between a pair of beams or rafters (2) with said first major surface (3) with the facing (20) entering first.
