It's a long way from raw materials through the mixture to the finished stone. Many plant components are involved in this process. Only if the system components are matched, can one be assured of a smooth process and economical operation of the block making plant.
It's a long way from raw materials over mixture to the finished (Kerb)stone. Masa Kerbstone presses were developed to fulfill among other criteria, the special requirements of the "British Standard" kerbstones. This "British Standard" is still a condition in countries of the Middle East and the UK.
The manufacturing of autoclaved aerated concrete products demands high standards for mixing and dosing of the aggregates, the control of the fermentation process and the control of each production step. Masa's aerated concrete installations are proven advanced technology processes, designed according to customers specific requirements. This approach allows complete solutions to ensure highly efficient, optimised processes resulting in consistent final product quality.

Masa LithoPore® is a mineral building material that is processed into a vapour-permeable thermal insulation panel.
Masa plants and machines are installed and commissioned by our own experienced fitters. Masa relies on qualified personnel, trained in Germany.
The Masa Lifetime service extends far beyond the actual assembly and commissioning of a plant. Masa can rely on specific know-how and an industry experience of more than 110 years.
Do you need support with your machine? Masa Support scores in both quality and significantly improved accessibility. Whether "first aid" for technical problems, updates, functional expansions of your production plant or technical questions, the know-how provided by Masa Support covers a wide range of services.
One of the keys to increasing productivity and quality is continuous training of the machine and maintenance personnel.

1. What is Masa-LithoPore®?
Masa-LithoPore® is a mineral building material that is processed into a vapour-permeable thermal insulation panel.
Masa GmbH concluded a cooperation agreement for the development and manufacture of Masa-LithoPore® with Luca Industries International GmbH, one of the leading companies in the field of development and production of bio-technological and chemical substances.
As of 14th January, 2015, the development phase could be completed with the issue of a general technical approval by DIBt (Deutsches Institut für Bautechnik, German institute for structural engineering).
Under the brand name Masa-LithoPore®, both cooperation partners together offer a complete system for the manufacture of thermal insulation panels.
2. Advantages
Masa-LithoPore® products can replace conventional insulating materials, such as expanded polystyrene (EPS) or mineral wool.
The insulation values reached are well comparable to those of other thermal insulation boards.
DIBt Approval
The main advantages are:
- mineral material
- noncombustible (building material class A1)
- vapour-permeable and capillary active, thus suitable for interior insulation (without using a vapour barrier)
- environmentally friendly and easy to recycle
- easy handling on the building site
- DIBt approved

4. Manufacture
Cutting system for Masa-LithoPore®
Masa-LithoPore® consists of water and additives. In addition, water is required for the manufacturing process. In a two-stage procedure, the basic materials are mixed homogeneously and fed into casting moulds. The filled casting moulds are then transported to the pre-hardening area. When the cakes have reached green strength (cutting strength), the casting moulds are removed and the blocks are cut to the size of the thermal insulation panels in the cutting line.
The cut cakes are placed on hardening cars and transported to the post-curing area. Before they are packaged, the surfaces of the individual thermal insulation panels can be hydrophobized.
Cut cake
A high-quality thermal insulation panel requires smooth handling. Therefore, the finished product has to be packaged in that way that it is protected from dirt and moisture before it is removed from the factory. Depending on the plant concept, this packaging process can be carried out automatically or semi-automatically.
Many plant components required for the manufacture of thermal insulation panels resemble those Masa machines that are used for the manufacture of aerated concrete.
