HD1012 Hush System 2003 Acoustic Floor Solution - Acoustic Floor and Ceiling System

The Hush Acoustics HD1012 System 2003 is a fully tested and economical sound insulation system designed for separating floors in refurbishment projects where the floor construction features timber joists.

The system utilises Hush Acoustics' high quality sound insulation materials to provide an effective treatment for reducing airborne and impact sound transmission. This is achieved by the creation of a floating floor by installing Hush Panel 28 acoustic boards, in conjunction with joist strips, seals, absorbers and Hush Bar resilient bars.

HD1012 is a fully tested complete system, which means complete assurance that it will deliver the acoustic upgrade sought in refurbishment projects. It is also compliant with all the relevant UK Building Regulations - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland).

Features and benefits:

• For use in refurbishment and conversion developments, where a joisted structure is in place.
• Building Regulations compliant - Approved Document E (England & Wales), Technical Handbook Section 5 (Scotland) and Technical Handbook G (Northern Ireland).

• Hush Panel 28, with all tongue and groove joints glued using Hush Bond, is laid over Hush 10 Joist Strips, secured to joist tops as instructed, and all perimeters are sealed using Hush Seal 20.
