Interfuse Interlyte-Ultra Lightweight 100mm Solid Low Density Concrete Block 7.3N

Interfuse Interlyte-Ultra Lightweight 100mm Solid Low Density Concrete Block 7.3N

Concrete blocks, also known as breeze blocks or masonry units.

Part of the Interlyte-Ultra range, this low-density concrete block is manufactured from a blend of lightweight aggregates. With a unit weight of just 9.5kg and a density below 1000kg/m³, it is significantly lighter than traditional dense concrete blocks, making it safer and easier to handle on site — especially for repetitive manual tasks.

This 7.3N version offers high compressive strength in an ultra-lightweight format, making it suitable for loadbearing applications, use below DPC level, and general structural work. It also provides good thermal performance and features a textured face suitable for plastering, rendering, or dry lining.
