FIBOLITE is an ultra lightweight load bearing block manufactured from Plasmors own man-made expanded clay aggregate. Expanded clay nodules are produced by sophisticated pyrogenic technology whereby geochemically specific clay is expanded in a rotary kiln at high temperature. The clay nodule is an extremely lightweight granular aggregate with a hard vitrified outer shell and an air filled honeycombed inner. FIBOLITE blocks are extremely lightweight, offer one hand lift laying, have excellent thermal efficiency values, provide an ideal key for plaster/render and accept fixings readily. FIBOLITE blocks are especially suitable for house building, extensions, repair, maintenance and refurbishment projects. The majority of the blocks in the FIBOLITE range comply with the 20kg single lift requirements of the Construction (Design and Management) Regulations.
