Building materials

"LAMBDA" has the excellent base material performance and design of cement board. It is lightweight but has the performance required for exterior wall materials such as strength, durability, weather resistance, and earthquake resistance, and is easy to process and install.
It also has a variety of designs with simple but diverse shapes and details.
In addition to these features, we have a wealth of construction methods that we have accumulated through our long experience in construction. It is an exterior wall material that can assist in the realization of optimal exterior designs for a wide range of purposes.

In terms of function, it also has high sound insulation performance against low-frequency sound, and realizes excellent sound insulation and light weight due to its hollow shape.
As a "lightweight sound insulation panel," it is used in factories where low-frequency sounds are generated, and as a sound barrier for air conditioning equipment.
