APPLICATIONS

Stramit® Acoustic Panels are suitable for applications such as school halls, gymnasiums, terminal buildings, open-sided covered walkways or wherever noise reduction is required.

MATERIALS:

Stramit® Acoustic Panels are cold roll formed cladding sheets produced from pre-perforated Colorbond materials. Steel is G550 base material (G550 MPa minimum yield stress) with a Zincalume® (AZ 150 coating, in accordance with AS 1397), plus an off white Colorbond® finish coat. Standard steel thickness is 0.42mm BMT (base material thickness). Other materials such as unpainted Zincalume® or galvanised steel, stainless steel, aluminium and copper can be roll formed subject to enquiry.

PERFORATION:

Stramit standard perforations cover approximately 11% of the cladding surface. Holes are 2.4mm in diameter and are pitched symmetrically across the sheet. This layout gives the best balance between appearance, ease of installation cladding performance and noise reduction. Should other hole patterns be required please contact your local Stramit Technical Services Manager.

TESTING:

Stramit has in-house purpose built testing equipment used to design, develop and improve products for the Australian market. In addition, Stramit products are tested or witnessed by independent organisations. Sound absorption tests on Stramit® Acoustic Panels have been conducted by National Acoustic Laboratories using the reverberation chamber method in accordance with AS1045. Results of these tests are shown in the graphs on subsequent pages. Should further information be required, please contact your local Stramit Technical Services Manager.

DURABILITY:

Many internal applications for Stramit® Acoustic Panels will be relatively benign. In applications of high humidity (eg pools) or having a corrosive atmosphere contact Stramit to discuss the optimum material choice.

Covered external applications, particularly walls, may be subject to dust, salt and other wind-blown pollutants. As these are 'unwashed' (by rainwater) areas careful choice of materials is needed. Talk to your local Stramit Technical Services Manager for advice.

ARCHITECTECTURAL SPECIFICATION:

A suggested specification is:-

The internal wall/ceiling shall be Stramit® Acoustic Panels in the profile. Sheeting material shall be protected steel sheet to Australian Standard AS 1397 with a minimum yield stress of 550MPa (Grade 550) and an AZ 150 zinc-aluminium coating with an Off White oven baked paint film.

The sheeting shall be fixed to the structure in accordance with the manufacturers instructions.

All sheeting shall be fixed in a workman like manner, leaving the job clean and with minor blemishes touched up with paint supplied by the manufacturer. All insulation/absorbing materials shall match the Stramit specification contained in the Stramit technical brochure.
