Delta 40 - Commercial Suite

Product Description

The Delta Commercial Suite was originally designed in the early 1970s and has been progressively upgraded and developed to become the clear market leader, renowned as being extremely robust and offering exceptional performance. The best testimonial for this product to substantiate the pedigree comes from Wispeco, the largest window manufacturer in the African Continent who have sought technology agreements from Thermosash for this suite.

Frame Size

Single- and double-glazed options are available.

- Fixed window frames: 41mm (non Seismic) | 61mm Seismic.
- Awning / Sliding / Hopper / Spinner window inserts: 30mm.
- Hinged Doors: 47mm Heavy Duty.

Integration

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).

All windows and doors can be integrated - refer drawing details for correct set outs, rebates and flashing details etc.
Single bank 40mm Mechanical Air Louvres can be integrated into aluminium doors.

Low-carbon aluminium windows, doors and sliders

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).

Thermosash manufacture all of our own façade components in New Zealand, and primarily source materials were available from the New Zealand market to reduce transport distances and emissions from freight. We recycle 100% of all our metal waste.

Performance / Testing

Thermosash owns and operates the largest façade testing facility in New Zealand where we test our systems and custom designed suites to ensure compliance with the below codes or project specific requirements:

AS/NZS1170 (Structural Design Actions)
NZS4211 (Performance of Windows)
NZS4223 (Glazing in Buildings)
NZS/AS4284:2008 (Water / Air Pressure/ Air Leakage - Meets and exceeds minimum requirements)

All the Thermosash suites are independently laboratory tested to IANZ (International Accreditation New Zealand). Test certificates are available on request.

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.

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: eg. 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

Adaptable system easily configured.

- Uniquely tenoned for strength.
- Specifically engineered sashes - with various configurations - sliding windows, awning, casement, hopper and spinner. Sashes can be glazed internally or externally.
- Can accommodate varying thickness of glass, DGU, or panel combination from 4mm to 28mm.
- Integrates with seismic frames or transoms.
- Integrated windows and doors.
- Single bank 40mm Mechanical Louvres can be integrated into aluminium doors.

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.
