Thermosash Alpha Glazing System

Product Description

Thermosash Alpha Glazing System - capped, skylight & atrium glazing bar systems. This design style of 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 or internally for skylights as well as an economical solution for factories, warehouses, hangers and grandstands, yet is a sophisticated and rated high performance solution for all high end skylight and sloped glazing applications.

Engineering

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 and engineered.

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 (eg high performance laminated and insulated glass units) used to overcome these particular problems without compromising their product warranties.

Innovation and providing custom specific design solutions has always been the foundation on which Thermosash has developed its suites. Our growth has been influenced by constant research and development and being aware of overseas trends.

Low-Carbon Aluminium

Thermosash partners with a local NZ-owned extruder achieving a lower carbon footprint than the global average - offering reduced upfront carbon emissions. (find out more about our Sustainable Aluminium).

Aluminium is 100% recyclable and all aluminium from refurbished sites and from our manufacturing process is environmentally managed back to our key suppliers and processed back into raw billet form.

Overhead glazing configurations include:

  • Lean-to skylights
  • Ridge skylights
  • Double pitch skylights
  • Pyramid skylights
  • Multi-facetted pyramids
  • Hip ridge skylights
  • Segmented barrel vault skylights
  • Curved barrel vault skylights
  • Vertical glazing

Section Sizes: range of 55mm - 80mm

Maximum Spanning Ability

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

Installation

Our systems are prefabricated and glazed in a factory environment, stored if necessary, and transported for just-in-time site delivery. We have highly skilled installation teams who work safely and effectively to close in buildings rapidly.

Warranty

The standard warranty is 5 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.
