Commercial Window & Door Suite (Heavy Duty)
The Delta commercial suite was originally designed and introduced to the New Zealand market by Thermosash in the early 1970s. Today, it is recognised as the market leader, having been specified and incorporated on a great majority of New Zealand’s noteworthy projects where product quality and longterm high performance levels are required.
The Delta Commercial Suite is a robust adaptable system which can be easily configured according to practical design parameters within the same perimeter frame, or seismic frame (if required). Adaptability includes various window sash configurations, sliding windows, doors, awning, casement, hopper and spinner (i.e. reversible) sliding sashes. All sashes can be glazed either internally or externally.
Glazing rebates comply with minimum required commercial glass engagements and edge clearances for sophisticated high performance architectural glass products (particularly insulated glass units). An important design requirement to obtain glass warranties.
Delta windows integrate with perimeter seismic frames and (where required) seismic transoms to meet specified vertical or horizontal building movements (internally or externally glazed). This generally enables installation of the product in high rise applications from within the building, removing the need for costly external scaffolding.
Specifically designed extruded sill trays are provided on all products to ensure rainscreen pressure equalised drainage principles are maintained. This design feature ensures fixings do not penetrate critical weathering lines and is particularly important with long-run coupled strip window units, a common feature on commercial window projects.
All the Thermosash suites are independently laboratory tested to IANZ (International Accreditation New Zealand). Test certificates are available on request.
Thermosash specifically engineers the best suite option for your project taking into consideration span, structural system, and environmental loads (e.g. wind).

- CategoryAluminium Joinery, Glazed Facade Systems
- Type of useCommercial
- InstallationProfessional installation required
- An extremely versatile product - outer frame construction - tenoned in a unique manner to provide a very strong and twist-free connection which removes the reliance on assembly screws for strength and small joint sealant for weathering of fabricated joints.
- An integrated wide ranging robust product range which can be fitted with awning, casement, hopper, spinner (i.e. reversible) sliding sashes and doors all within the same frame design - inside / outside glazed and seismic frame.
- Sashes are mitred and crimped or cleated to provide superior torsional strength, enabling large sashes to be provided and which are capable of large spans.
- Sashes are designed with pressure seals internally (rear airseal) and externally to the heads and jambs to provide high performance rainscreen pressure equalised weathering.
- Sashes have an integral drainage channel in the web of the section, eliminating the need for externally applied weather bars.
- The system is generally dry glazed with high quality Santoprene gaskets.
- Glazing rebates of 22mm comply with minimum required commercial glass engagements and edge clearances for sophisticated high performance architectural glass products (particularly insulated glass units). An important design requirement to obtain glass warranties.
- Delta windows can accommodate virtually any thickness of glass or panel from 4mm to 28mm.
- Delta windows integrate with perimeter seismic frames and (where required) seismic transoms to meet specified vertical or horizontal building movements (internally or externally glazed). This generally enables installation of the product in highrise applications from within the building, removing the need for costly external scaffolding.
- Specifically designed extruded sill trays are provided on all products to ensure rainscreen pressure equalised drainage principles are maintained. This design feature ensures fixings do not penetrate critical weathering lines and is particularly important with long-run coupled strip window units, a common feature on commercial window projects.

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.
We recommend using Masterspec 4251TS Commercial Windows when specifying this suite.
