Insulite is a range of lightweight (density 1400 kg's / m3) load bearing building blocks manufactured in the main from re claimed and re cycled raw materials conforming to BS 3797. The products themselves are manufactured to BS 6073: Part 1. The blocks are cast in steel moulds onto steel pallets and compacted by vibration, following which they are placed in specially designed chambers where the curing process of the green concrete is accelerated by means of humidity. The compaction process of the concrete is vital to the quality of the finished product. At Besblock we employ Columbia presses. These are internationally acclaimed as the very finest in their field and their unicontrolled vibration system ensures even density and compaction within the mould, giving a consistent test quality on every block.
