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 creating a separating lightweight stud wall.
• Excellent acoustic performance due to the clear void between the two stud frames.

How HD1054 is formed:

• Create two frames of 50x100mm timber stud work.
• Isolate the stud and track from the floor and ceiling structure using the Hush Heavy Duty Isolation Tape.
• Ensure there is a minimum 50mm clear gap between the two stud frames which remains clear.
• Insulate within the stud frames using the Hush-Slab 100 Sound Absorber. This must be installed tightly within the stud frame and continue to ensure the cavity between the frames remains clear.
• Face each stud frame with two layers of 15mm Soundbloc plasterboards.
• Seal the perimeters of the plasterboards using Hush Acoustic Sealant.
