| 摘要 |
A mineral fibre board having at least two resilient edges in order to prevent any small gaps in the joints between two adjacent boards when these are installed. The purpose of the invention is to improve the effect of the insulation layer and thereby either reducing the heat loss to a minimum in order to comply with new standards for low energy consumption buildings or to improve the fire properties of a fire protection insulation layer on e.g. steel constructions. The invention also concerns a method for producing the mineral fibre board by mechanical compression by rollers.
