High performance acoustic insulation system HD1055 for masonry wall with stud lining

The HD1055 Masonry Wall with Stud Lining System from Hush Acoustic provides a superior solution for upgrading the acoustic performance of a masonry wall. It is a fully tested system that combines several high quality soundproofing products that can be used in new build, conversion (material change of use) and refurbishment projects.

The system works by creating a clear void between the existing masonry wall and the new timber stud wall. It is fully compliant with all the Building Regulations covering the UK - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland).

The system is constructed as follows:

• A single frame of 50x100mm timber stud work is constructed independently from the existing masonry wall. Ensure there is a clear 25mm minimum gap from the existing masonry to the stud frame.
• Ensure the stud and track is isolated from the floor and ceiling structure using the Hush Heavy Duty Isolation Tape.
• The stud is insulated using the Hush-Slab 100 Sound Absorber. This is installed tightly within the stud frame, ensuring the gap from the timber frame to the masonry wall remains clear at all time.
• The masonry side and the new timber frame are then faced with two layers of 15mm Soundbloc Plasterboards. Ensure the perimeters of the plasterboards are sealed with the Hush Acoustic Sealant.
