The first robust detail to qualify for the maximum sound insulation credits under the Code for Sustainable Homes has been revealed. E-WM-19 is based around Icopal Monarfloor’s Bridgestop acoustic isolation system for masonry separating cavity walls
The system incorporates an Ancon HRT4 stainless steel wire wall tie, which comes in three lengths for cavities from 50mm to 125mm.
Robust Details assesses and approves separating wall and floor constructions for use in new-build, attached dwellings that are capable of consistently exceeding the performance standards of Approved Document E - the resistance to the passage of sound. Contractors can implement robust details to avoid test procedures and extra costs.
