Cassette - Rainscreen Systems

By Thermosash
Website

A façade suite that incorporates a rainscreen cassette system has many advantages over a proprietary panel on rail system because the cassette is generally designed to be installed over a unitised system that integrates the air seal (and insulation). This is the key flexible advantage that allows the designer to freely design flat or 3-dimensional panels over the façade, which under normal circumstances may become complex or even impossible junctions to manage with regard to weathering.

A cassette system may incorporate folded ACM, zinc, stainless steel, surface finished aluminium or terracotta.

Thermosash have engineered a unique method of fitting of brackets that eliminate potential wind uplift and, because of the unitised panel supporting the cassettes, also absorb seismic or differential structural movements without compromising any of the junction or critical weathering detailing.

Scope of use

Commercial low rise or high rise buildings.

Features

An extremely adaptable system that allows bespoke designed elements to be incorporated confidently, with no concern of creating complex junctions that will leak.

  • Minimizes junctions between trades.
  • Versatile bracketing system that allows for a vast variety of materials to be incorporated.
  • A system that allows seamless integration of ancillary components such as brackets for solar shading, signage brackets etc that do not penetrate the wet zone, thereby eliminating the chance of leakage.

Section & Panel Sizes

As the cassettes or panels are generally fixed over a panelwall (PW) system the primary structure, air barrier and insulation panel section size is either 100 / 150 / 200mm + the cassette section, which is generally only limited by the original material size availability or the receiving panel - optimized to manage waste / control cost. 

Specification 

We recommend using  Masterspec 4211TS Thermosash Curtainwalling when specifying this system.

Surface Finishing 

Whilst a cassette system could be made up of practically any folded metal such as stainless steel, zinc or steel, when specifying aluminum the following finishes are available:

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)
  • NZS4223 (Glazing in Buildings)
  • NZS/AS4284:2008 (Water / Air Pressure/ Air Leakage - Meets and exceeds minimum requirements)

Maximum Spanning Ability

Thermosash specifically engineers the best suite option for your project taking into consideration span, structural system, load imposed by the cassettes and wind loading. 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.

“Our work at Thermosash is critical to the building industry. Our prefabricated design specific engineered building envelopes shape the appearance of our skylines: offering comfort to occupants from heat and cold, protection from the elements, respite from the acoustic discomfort of busy cities and pleasure to those who appreciate the built environment”. David Hayes, Group Managing Director.

Our growth since 1973 demonstrates that the strength we offer the building industry is underpinned by supplying quality, long lasting, engineered building envelope systems. Our ability to meet tight lead times and on-site programmes, our acceptance of transfer of design responsibility, our engineering, manufacturing, logistics and on-site capabilities, together with our team’s passion and quality service commitment enables us to remain at the forefront of the facade subcontracting industry.

Our Expertise
Thermosash’s abilities have grown since its 1973 start-up when Laurie Hayes and his colleagues manufactured commercial windows out of a small production facility. It quickly became apparent that the products and skills of the workforce were creating a performing quality, flexible product that the market sought.

Over time, our teams of dedicated and committed people have grown, this has been possible through constant reassessment of internal and external processes and manufacturing methods from around the world. We’ve also provided ongoing reinvestment in the training of our people to ensure lean process, IT Systems, material handling machinery and transport logistics equipment, as well as design office and factory production process improvements. We are able to offer a world class company with manufacturing facilities in Auckland, Wellington and Christchurch.

Our Offering
We offer an extensive range of cost effective, high performance rainscreen, pressure equalised window, door and façade solutions to suit any commercial project. Our products are incorporated in high-rise office blocks, apartment buildings, shopping centres, airports, institutions, hotels, industrial complexes and quality architectural homes.

In addition to offering bespoke façade solutions for new builds, we are experts in recladding, rainscreen over-cladding and the refurbishment of existing façades.
