Is the sound insulation as good in a Timber Frame house as it is in a brick and block house?
In the past many timber frame houses did not have insulation put into the internal panels which gave people the impression that this form of construction was noisy. Taylor Lane supply semi-rigid batt insulation to all panels for the client to fit between the studs. Tests have shown that a 90mm internal panel has the same sound reduction qualities as a single block internal wall.
Sound insulation is at its most important with party walls and floors between houses and flats in which timber frame construction also performs extremely well.
