Acoustic Underlay for a Semi-Detached House — Guide

Written by our acoustic insulation specialist — 15+ years experience. About our experts.

Semi-detached house owners face a specific acoustic situation: the shared wall with the neighbouring property is the primary concern, but floor treatment can still make a meaningful difference.

The Semi-Detached Noise Profile

In a semi-detached house, noise most commonly travels through the shared party wall (TV, music, voices from next door) and through your own floors between storeys. Acoustic underlay directly addresses the latter.

Floor Treatment for Semi-Detached Houses

For upper floors in a semi-detached house: our 6mm rubber underlay (74dB) under your hard floor finish significantly reduces impact noise reaching ground floor rooms. This is particularly valuable if you have children whose bedrooms are above a living area, or if you work from home on the ground floor.

Party Wall Treatment

For the shared wall, acoustic underlay is not the right product. An independent wall lining with acoustic mineral wool is the most effective approach. Our acoustic mineral wool products are available in the range — see our wall soundproofing guide for details.
