This lightweight coursing unit is made from aircrete, measuring 215 x 100 x 65mm, and is designed for use where infill pieces are required in blockwork. It is typically used above doors and windows, at floor and ceiling levels, or between joists where full-sized blocks are unsuitable or awkward to fit.
On site, these units help avoid thermal bridging in wall construction, providing a practical solution for closing small gaps and achieving continuity in cavity wall builds. They are not intended for use in the construction of full walls but are well suited for infill duties where a compact, easy-to-handle block is needed.
