GENERAL

If you have pre-customised this work section using the "questions and answers" provided as part of the downloading process, it may be necessary to amend some clauses to suit the final project-specific version.
The section must still be checked and customised to suit the project being specified, by removing any other irrelevant details and adding project-specific details and selections.

 

This section relates to Woodland Lifestyle Limited GenieMat® RST acoustic underlay.

 

It includes:

Modify / expand this clause to suit requirements of the final version of the section.


GenieMat® RST acoustic underlay for carpet, carpet tiles, ceramic tiles, vinyl plank flooring, vinyl sheet flooring and engineered timber flooring on concrete, plywood, particleboard and fibre-cement board substrates.  Suitable for commercial, retail, institutional, residential and multi-unit dwelling applications.  Underlay can be used in wet areas in conjunction with a suitable waterproof membrane system applied to substrate prior to installing underlay.


GenieMat® RST is not currently tested to the standards cited in NZBC G6/AS1 & VM1 for determining Impact Insulation Class (IIC) and Sound Transmission Class (STC).  Woodland Lifestyle can provide IIC and STC test results for specific build ups for guidance.  Compliance with NZBC G6/VM1 will require site testing to measure actual performance.  Refer to Woodland Lifestyle for specification guidance.
