YOSHINO Renovation System (Improves levels of sound insulation of existing walls)

YOSHINO Renovation System is designed as the sound insulation wall for flats, apartments or hotels.

The required levels of sound insulation was not so demanding about 20 or 30 years ago, however, in recent years the demand has been significantly increased. In fact, the required level of sound insulation is from 5 dB to 10 dB higher than used to be.
Yoshino introduces the renovation systems to improve levels of sound insulation of existing walls to meet the public demands.

Renovation Work for Anti-Seismic Reinforcement
Most houses built more than 20 or 30 years ago can not resist horizontal force generated by earthquake or typhoon.
12.5 mm Tiger Glass Rock is the most suitable plasterboard to provide anti-seismic structural reinforcement for those houses without demolition of existing walls.
The shear wall incorporating Tiger Glass Rock can bear vertical force generated by earthquake or typhoon and reduces distortions occurring to entire buildings owing to its excellent flexural strength

Renovation Work for Improving Air Quality
(All you need to do is just applying Tiger Glass Rock Clear to existing walls!)
Tiger Glass Rock Clear is a 4 mm decorative sheet with formaldehyde absorption and decomposition performance. The levels of formaldehyde in a room can be reduced by using Tiger Glass Rock Clear as refurbishment. Additionally, it offers extra fire protection as well.
