The laminates have a core of rigid isocyanurate-based foam sandwiched between two facing sheets which are preferably non-combustible. Embedded in the core, substantially throughout its thickness, are multiple layers of a mesh of continuous glass fibre strands which is readily permeable to the foam forming ingredients. Each layer of the mesh is substantially parallel to the facing sheets. The laminates show advantages over laminates reinforced with single filament surface veil mat, single filament expanded mat, single filament random swirl mat and continuous rovings. |
