Strandfloor®

Overview

The system is a lightweight timber construction fire and acoustic inter-tenancy flooring system. The floor system uses two layers of Strandfloor®, the first layer fixed to the timber or steel floor joists and the second layer fixed into wooden battens over a rubber cradle creating a floating floor (Batten & Cradle™). The system also offers solutions for timber joist, CLT and concrete slabs as an overlay in new and existing builds. The system is ideal for inter-tenancy floors in apartments, multi-unit residential, hotels, healthcare, retail, mixed use and office complexes.

Strandfloor® is a 20mm thick sheet with strands of wood pressed together under heat and pressure, that can also be treated to H3.1. Sheets can be specified as square edge or can include a polypropylene tongue for tongue & groove (T&G) fixing (T&G only used on the Batten & Cradle™ layer).

Application

With the growth of medium to high density residential housing, there was a need for an alternative wood-based solution that would address the issue of midfloor acoustic noise in multi-level tenancy buildings.

Acoustic performance of STC 65 / IIC 56 meaning there is less noise in adjoining rooms/areas. The acoustic performance values are tested on a raw floor (no floor coverings). Improved acoustic performance is achieved with installation of floor coverings, refer to GIB® Noise Control Manual, GBDFA 60e
Fire performance of FRR 60/60/60 tested by BRANZ (Appraisal 394)
StrandfloorH3.1® provides a wet area solution
Concentrated load of 3.6kN and uniform distributed load of 4kPa (office and retail loadings as defined in AS/NZS 1170) providing concentrated or even weight distribution
Strandfloor® is lighter than comparable solutions
Strandfloor® & StrandfloorH3.1® engineered wood panels do not require specialist cutting equipment
Multiple sheet sizes available — 3600 x 1200mm and 2400 x 1200mm
Battens can be up to 190mm to allow for services in Batten & Cradle™ cavity – an advantage for CLT construction

Benefits

The system is lighter than comparable solutions such as concrete & steel construction or fibre cement solution
Sheets are lighter and easier to handle
Easy to install, less complicated than other types of systems on the market
Does not require specialist cutting equipment, can cut on site with standard carpentry tools, no silica dust management on site required if compared with fibre cement solution
Lightweight timber frame construction has advantages over heavier systems in certain ground conditions
To future proof installations during renovation work, acoustic performance can be achieved with no reliance on carpet or acoustic underlay, especially if hardwood flooring or tiles are used
