Mechanically Engaged Overhead Canopy

Product Description

The mechanically engaged overhead glazing employs an aluminium extrusion that encapsulates a minimum of two edges that are then connected back to the primary structure.

The Thermosash Alpha Glazing Suite can be used externally for canopies and as a sophisticated and high performance solution for all high-end skylight and sloped glazing applications. It is also an economical solution for factories, warehouses, hangers and grandstands.

Engineering

The sophistication required of products used in overhead glazing can often be overlooked; the special design features required to cope with considerably higher water loadings, heat gain or loss (which introduces condensation) and in particular the risk associated with accommodating costly higher specification products (e.g. high performance laminated and insulated glass units) used to overcome these particular problems, without compromising their product warranties.

Due to potential exposure to high wind, seismic, snow, and live loads etc, it is necessary for these types of systems to be specifically designed.

Performance / Testing

AS/NZS1170 (Structural Design Actions)

NZS/AS4284:2008 (Water / Air Pressure/ Air Leakage)

Maximum Spanning Ability

Glass size and primary structure support is your only limitation. We can source your specific glass requirements to meet your project needs.

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 for these products. 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

Alpha glazing suite integrates with the Thermosash Delta Suite.

Can be installed to a minimum slope of 3^{o (based on maximum glass deflect}

Integral drainage cavities.

Commercial glazing engagements to cope with higher wind loads.

Condensation control (where specified).

Thermal break.

Ability to provide a different colour from inside to outside.

Can accommodate all recognized glass thicknesses used in commercial glazing.

Special splicing and connection features critical for weathering.

Almost any type of glass can be incorporated including ceramic fritting to provide an element of solar shading corporate motif.

The Alpha range can incorporate opening sashes or banks of louvres - BMS operated if required.

The Alpha systems are dry glazed unless aesthetically otherwise required.

Bars are designed to accommodate co-extruded backing gaskets to minimise long term shrinkage problems.

Glass is retained with gaskets fitted inside and out, primarily as a weather seal, but also to cushion against vibration and potential glass breakage.

Specification

We recommend using Masterspec 4521TS Commercial Windows when specifying this suite.
