Prefabricated house internal wall elements

Internal walls consist of 75, 95, 145, 195 mm construction wood frame and mineral wool sound isolation. The thickness of the walls mainly depends if the wall is bearing or partitioning, also, if there are going to be any installations inside the wall (e.g. toilet, ventilation channels etc.). Internal wall elements are already covered from one side with any of your chosen material like OSB board, gypsum board, wooden panels or other. We recommend our clients to use OSB and gypsum boards combination because of the increased strength, especially if there will be a need to hang something heavy on the walls in the future. Also, such combination increases sound isolation and makes internal walls virtually unbreakable, however, it is important to mention that extra boards increase the price of the house.

Resistance to fire and sound isolation

It is possible to use special fire-resistant gypsum boards and to increase their layers up to 3 from each side if there is a need for additional fire-resistance characteristics. For sound reduction it is possible to use mineral wool isolation or special sound isolation boards. If the internal walls are partinioning different apartments then special construction wall is used with double sound and fire isolation.
