Welcome to the AW Lumb website


The Insulite Lightweight block is the perfect, traditional all-round building block. They are cost effective, simple to use and provide an ideal background for accepting renders and plasters. The vast majority of raw material used in Insulite Medium Density lightweight blocks is fully recycled or reclaimed. In fact, over 90% by weight of these blocks consist of recycled materials, predominantly Furnace Bottom Ash (FBA) which would otherwise be landfilled.

Insulite is available in Standard texture for all background block applications and closer textured 'Premier' finish for smoother-faced, paint-grade applications.

The sizes available are 75mm, 90mm, 100mm, 140mm & 190mm and the Compressive Strengths available are 3.6N/mm², 4.2N/mm², 7.3N/mm² & 10.4N/mm².
