Simlay Commercial Underlay
Description

For double-stick installation in commercial areas where staff and client comfort is needed, Giltgrip Simlay is a SBR rubber sponge underlay designed for Double Bond installation. It is produced in a continuous sheet with square trimmed edges.

The double-stick system means rapid installation with no rucking or stretching of carpet, with an up-to 50% increase in carpet life compared with conventional and direct-stick methods.  Simlay is anti-microbial and anti-allergenic.

  • Thickness: 4.7mm
  • Weight: 1430g/m²
  • Roll Size: 1.8m x 10m
Key Features
  • Ease of installation
  • No need to re-stretch carpet over time
  • Lower wear as a result of less carpet deformation gives much improved lifetime cost of installation
  • Superior texture retention
  • Eliminates seam peaking in Axminsters (and other carpets)
  • Lends well to custom bordering and design work
  • Quieter: approximate 40dB FIIC rating improvement over the bare slab performance

 

Scope of Use
  • Suitable for commercial applications such as offices, educational institutions, hotels, healthcare, Government buildings, and entertainment facilities

Please refer to a Gilt Edge Industries Ltd technical representative for detailed guidance on applicable underlay types.

Limitations on Use
  • This system is not intended for:
    • Use on concrete substrates without an industry standard below slab damp-proof membrane
    • In situations where the below slab damp-proof membrane has been compromised
    • Substrates with RH greater than 75%
    • Situations exposed to hydro-static pressure
  • Base substrates are to be of sound form/condition free of any structural delamination
  • Not recommended for areas subject to very high point loading e.g. loaded pallet trolleys/hoists
  • For underfloor heating refer to supplier for specific suitability
Statement of Building Code Compliance

Independently tested and certified to standard AS4288-2003 Soft Underlays for Textile Flooring.

Fire Rating: 

Simlay SBR Latex in assessment of Critical Flux Radius and Smoke development Rate as tested by CSIRO in 2013 in their report #923.

Results: SBR Latex Underlay as per conditions specified I the test report will satisfy Performance Requirement CP4 of BCA 2013.

Acoustics:

  • Norman Disney and Young 2017 File #:a92768\003\J-\21\ca171127a0011

The NZBC calls for the IIC rating between inter-tenancy floor-ceiling constructions to be a minimum standard of 55 when tested in the laboratory situation. The code then makes and allowance of 5 dB or 5 IIC points for the same construction when tested in situ, i.e. FIIC 50.

To determine the impact insulation performance of the underlay product, the performance of the product was assessed against the performance of the bare slab. In result, the installation of both underlay products provided an additional approximate 40dB FIIC rating improvement over the bare slab performance.

Emissions Test Certificate:

CETEC: Carpet & Rug Institute Green Label test program incorporating ASTM D5116 'Standard Guide for Small-Scale Environmental Chamber Determinations of Organic Emissions from Indoor Material/Products'

Passes Institute Green Label Specification
