Mechanical Louvres Summary


Thermosash has developed a high performance range of single and double bank mechanical louvre systems that integrate into the Thermosash range of curtainwall, panelwall and commercial window systems for façade integrated mechanical air inlet and extract requirements.

These louvres are commonly specified as fresh air inlets for mechanical plant and mechanical plant screening. Double bank when a greater degree of weatheringproofing is demanded.

Product Features

  • High performance air inlet and extract. 
  • Fully drained system.
  • Engineered performance. 
  • Integrated vermin guards.
  • Can be 100% integrated with Thermosash suites - one provider

Section Sizes

  • Single-bank = 40mm
  • Single-bank = 100mm 
  • Double-bank = 100mm


We recommend using the following when specifying this type of suite - however on complex projects, because of the potential unique and high performance design requirements, a bespoke specification will be created by a consultant mechanical or façade engineer:

Masterspec 4211TS Curtainwalls Masterspec
4251TS Commercial Windows

 Please call us to discuss your project early in conceptual development.

Surface Finishing 

As the system is predominantly aluminum, the following surface finishes are typical;
Polyester powdercoat - Both standard and special colours available.
Anodised - All anodised colours available - commercial grade 20 micron finish recommended.
PVF2 Flourocarbon finishes - Available on request.

Performance / Testing

  • AS/NZS1170 (Structural Design Actions) 
  • Other codes as specified by the consultant mechanical engineer 

Maximum Spanning Ability

Thermosash specifically engineers the best suite option for your project taking into consideration span, structural system, and environmental loads (e.g. wind). The spanning ability will vary depending on the above. 

Thermosash Suites are recognized as having the largest spanning systems on the market due to our specific engineering capability and the customised nature of the work we complete.


The standard warranty is 10 years from the date of practical completion for these products. This covers workmanship and weather tightness, providing the subcontract includes fabrication, installation and glazing of all components.
