Abstract: The invention relates to a method for the production of a rigid PIR foam composite containing man-made vitreous fibres (MMVF), the method comprising: providing MMVF, wherein at least 50% of the fibres by weight have a length of less than 250 μm; providing a polyol component; mixing the MMVF and polyol component in a ratio such that the amount of MMVF is at least 10% by weight based on total weight of polyol component; emulsifying pentane with the mixture of polyol component and MMVF; inducing foam formation by addition of a further component which comprises isocyanate.
