摘要
A film laminate with at least one diffusion-barrier layer for production of a vacuum insulation panel, which can be used in the construction sector, has on at least one surface a heat-sealable polyolefin layer. Within this layer or on an external individual film or within a co-extruded composite that comprises at least externally a polyolefin layer, the polyolefin is provided with an effective amount of a flame retardant or of a mixture of flame retardants. This film laminate permits production of vacuum insulation panels which can be used in the construction sector, because when tested to DIN 4102-1 they meet the specifications for construction class B2.
