Foamed Concrete
Hollow-Core, Interlocking Panels


For serious business enquiries about these blocks please contact our business partner, THT International, who are the manufacturer of lightweight foamed concrete blocks and the manufacturer of the equipment for making the blocks.

Build Walls Quickly with 1.2m Pre-Cast Panels

Foamed concrete (CLC) panels can be used to build partition or non-load bearing walls. These pre-cast panels have hollow cores to reduce weight and gooves so that they interlock. They are made from 950 kg/m3 foamed concrete so they have plenty of strength, but due to the hollow cores the overall density of the panel is 633 kg/m3. Since the panels are bigger than blocks, it is much quicker to construct a wall with the panels. Another similar design are 60 x 50cm interlocking panels.

Pre-Cast Panel Advantages

The relatively large size compared to regular size blocks, and the interlocking design, means that these hollow core foamed concrete (clc) panels can be assembled into a wall far more quickly than regular sized blocks can.

They are easy to handle since each panel can be lifted by two workers and/or by using simple lifting equipment.

The hollow cores mean that less material is used to make the panels. The overall density of the panel being 633 kg/m3 compared to typically 800 - 1200 kg/m3 for regular sized foamed concrete blocks.

The low weight of the panels means that there is reduced loading on the building. This means that cost savings can be made on structural elements and foundations.

The hollow cores make convenient conduits for services such as pipework and cables.

Foamed concrete is fire proof and it provides good thermal and acoustic (sound) insulation.

Pre-Cast Panel Specification

  • Dimensions: 1200 x 500 x 100 mm
  • Weight: 38 kg
  • Density of foamed concrete: 950 kg/m3
  • Overall density of panel: 633 kg/m3

Panel Production with Wire Cutting Machine

To make the pre-cast panels, foamed concrete is poured in to a large mould which includes tubes to make the hollow core. After 3 - 4 hours the large block of foamed concrete can be cut with an automatic wire cutting machine to make 12 panels. Once the panels have set for a bit longer the tubes for creating the hollow cores can be removed. As with foamed concrete blocks, the panels must be cured for 28 days before they are used.
