Cassette Rainscreens

Product Description

A façade suite that incorporates a rainscreen cassette system offers clear advantages over a proprietary panel-on-rail system because the cassette is typically designed to be installed over a unitised system that integrates the air seal (and insulation). This key flexibility allows designers to freely design flat or three-dimensional panels over the façade, which under normal circumstances may become complex or even impossible junctions to manage that could compromise weathering.

Materials for cassette systems can include 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.

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.

Maximum Spanning Ability

The spanning ability will vary depending on the structural system and environmental loads (e.g. wind). Thermosash specifically engineers the best suite options to meet project requirements.

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.

Warranty

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

Maintenance

Maintaining glass, metals and stone are all particular to the environment that they are placed in: e.g. marine, environmental pollution, exposure to natural washing, etc.

It is recommended by almost all material suppliers that building washing should occur every 3-6 months to prevent staining to glass and prevent environmental pollutants from corroding metals and to maintain the material warranties.

A full maintenance manual is provided on completion of a project for all the elements integrated within a project. Compliance to a maintenance schedule is essential to maintaining the quality of the installed product over time. Using Thermosash-approved facade maintenance contractor/personnel ensures the highest standards are met.

Key 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.
