HD1055 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.

Features and benefits:

• Can be used in new build, conversion and refurbishment developments.
• Provides a one-hour fire resistance.
• Building Regulations Approved Document E (E&W), Technical Handbook Section 5 (Scotland) and Technical Handbook G (Northern Ireland) compliant.
• A tried and tested method of upgrading an existing masonry wall to separating wall standards.
• Excellent acoustic performance due to the clear void between the existing masonry wall and the new timber stud wall.

Performance is assured as it is a fully tested system that combines several high quality soundproofing products, providing a solution for new build, conversion (material change of use) and refurbishment projects.

HD1055 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).

How the system is formed:

• A single frame of 50x100mm timber stud work is constructed independently from the existing masonry wall. A clear 25mm minimum gap is needed between the existing masonry and stud frame.
• Isolate the stud and track from the floor and ceiling structure using the Hush Heavy Duty Isolation Tape.
• Insulate the stud wall using Hush-Slab 100 Sound Absorber. This is installed tightly within the stud frame, ensuring that the gap between the timber frame to the masonry wall remains clear at all time.
• Face the masonry side and the new timber frame with two layers of 15mm Soundbloc plasterboards.
• Seal the perimeters of the plasterboards using Hush Acoustic Sealant.

In addition to providing excellent acoustic performance, HD1055 meets the requirements of fire safety with a 1 hour fire resistance rating.
