CJ BLOK® PK AG-12 ACCOUSTIC BLOCK 6N 373x120x248

Product Description

Expanded clay and perlite acoustic hollow block is a high class ecological element of the ENERGO group with unique technical features. It is ideally suited for the construction of partition walls between rooms. It has excellent noise protection and high vapour permeability, which ensures a pleasant atmosphere in the room. In addition, it is very resistant to fire and produces no toxic substances in the event of a fire. Walls made of PK AQ-12 are recommended to be installed in horizontal and vertical joints. Durable structure of the hollow block allows for using thin layer mortars. Despite the small width, this product is very stable during masonry due to the use of a tongue and groove in the vertical joint. The hollow block's well designed wall thickness and air ducts makes it easy to run electrical and plumbing installations and protects against excessive damage to the unit. The product is also easy to machine.
