Description

The Metra Panel System is a building system based on Metra Panel wall, floor and ceiling panels. The design and construction of the remainder of the building, comprising foundation, flooring, roof, joinery and claddings, is conventional.

Moisture-resistant (MR Superfine) 36 mm thick medium-density particleboard is used for Metra Panel wall panels, and 25 mm thick, fine surface, MR Superfine particleboard is used for Metra Panel ceiling and floor panels.

External walls have vertical timber battens attached to the exterior face of the Metra Panel wall panels that act as stiffeners. Lintels are also constructed from Metra Panel wall panels and strengthened depending on the spans by means of additional timber beams or with steel plates to form flitch beams.

The ground floor, first floor and the roof are of conventional construction. Structural connections are made with nails, screws and various proprietary hardware.

After erection, Metra Panel wall panels have an internal finish system applied, such as paint or wallpaper, and conventional external cladding systems are fixed to the battens.
