PANEL FOR INTERNAL WALLS, SURFACE MATERIAL OF WHICH IS NOT GLUED BUT IS WRAPPED AROUND BASE MATERIAL Russian patent published in 2010 - IPC E04C1/00 E04C2/24 E04F13/72 

FIELD: construction.

SUBSTANCE: panels comprise base material and surface material, at the same time surface material is not attached to front surface of base material, but is fixed only to edge section of back surface of base material. However, surface material covers front surface of base material and edge section of back surface of base material. At the same time base material comprises structure with noise-suppression grooves, which are open on front surface of base material and have diametre from 1 to 20 mm, interval from 10 to 50 mm and depth from 15 to 30 mm. Method for manufacturing of panel for internal walls includes the following stages. At first base material is provided with structure with noise-suppression grooves, which are open on front surface of base material and have diametre from 1 to 20 mm, interval from 10 to 50 mm and depth from 15 to 30 mm. Then base material is bent. Afterwards surface material is attached and fixed to one side of edge section of back surface of bent base material, and front surface of base material is covered with surface material, simultaneously providing for tension of surface material, and finally surface material is fixed to other side of edge section of back surface of base material.

EFFECT: higher noise suppression.
