What is Alustone?

The natural stone plate Alustone is an epochal product developed by Foamtech. Alustoneis manufactured with 3mm thin layer of natural marble and aluminum foam panel.

Aluminum foam is a new concept metal that forms sponge shape. The product is made byspecial treatment of aluminum ingot with various chemical ingredients. Aluminum foamperforms light weight, acoustic and impact absorption function, inflammability, etc due to themultiple porous.

Alustone is even better than natural marble. It is lighter and stronger than natural marble.Due to the light weight, it perfectly reduces delivery cost and improves workability.

With light weight and solidity, it can be used in a wide range of fields including interior,exterior of buildings, container, transportation vehicles, furniture, elevators, etc.

Alustone is produced with only the finest natural stone from Italy, Spain and other limitedcountries, and manufactured by the skilled engineers with the cutting-edge technology. Ithas obviously differentiated quality from low quality marble composite panels made in China.

Alustone is highly efficient material in terms of weight(1/5 of natural marble). The property ofAlustone can shorten construction period, delivery cost and labor fee.

FlatnessFlatness of foundation must be within 3mm per every 2.4m of wall and 3㎜ per 3m of floor.

Treatment All impurities must be cleaned by inspection before attaching products.

Bonding method(Epoxy type glue for binding stone)(1) Dry the bonding surface sufficiently(over 1 week in summer, over 2

weeks in other seasons). (2) Flatten the surface with filling material in case of rough surface. In this

case once plaster area must be less than 2㎡ with trowel. (3) The products must be attached after checking the condition of adhesion

and hardening of surface and ventilated properly.

Pressure method (1) Spread thin mortar after plastering flatly than attach Alustone on the

surface. If necessary, spreading mortar on the back side of Alustoneand attaching is possible.

(2) Enhance adhesive power and durability with synthetic resins.
