Structural Laminated Flooring

Description

Techlam laminated T&G flooring (with or without V) is a durable, structural flooring system that is manufactured in accordance with AS/NZS 1328:1998 and AS5068.

Supplied in a Grade A Visual or Utility non visual finish, the flooring is manufactured from random lengths of timber (Radiata Pine), which are finger jointed and glued together to form continuous laminations. Available in two widths (300mm and 240mm) and in thicknesses of 42-135mm, this product can be manufactured to any specified length.

Key Features

Fast and easy to install
Aesthetically pleasing
Large spans can be easily achieved
Floor depth is significantly reduced
Less requirement for structural support (greater distance between floor support beams)
Good fire resistance (up to 150 Minutes depending on product selected)

Scope of Use

Techlam laminated T&G flooring can be used in all forms of construction where the structure relies on AS1170:2002. Techlam laminated T&G flooring Span Tables are based on 'live load' categories (KPa) and vibration limitations, which are subject to the use of the space/building. The design and use must be in accordance with the Techlam GL10 laminated T&G Span Tables (see www.techlam.co.nz).

Limitations on Use

Techlam laminated T&G flooring must be kept dry and stored flat. If it is to be coated, application of the coating must be in accordance with the manufacturer’s instructions. If the moisture content is allowed to vary, the timber will be subject to shrinkage and swelling which may lead to cracks and shakes appearing.

Other Performance Attributes

Fire Performance: The fire resistance rating (FRRmax) for the floor systems are determined for the maximum allowable spans (Lmax) and cantilever length (Lc,max). It is assumed that only the underside of the floor is exposed to fire and that the char rate of the timber is 0.65mm/min.
