Residential Joinery

Introduction 

Thermosash's most commonly specified residential suite is our Montana suite that incorporates all our unique Delta commercial suite features and is capable of large spans and high performance applications such as high wind or acoustic reduction demanding sites.  

The prestigous homes that specify Thermosash often also incorporate other systems such as structural glass walls, glass floors or steps, glass balustrades and skylights etc.

Thermosash residential windows are both elegant and practical, incorporating the very latest design features which have been time tested and meet and exceed the standards set down by our New Zealand codes.

Due to demands of specific design architectural homes, our in-house engineers assess the project requirements and specify the most appropriate and economical solution.

Thermosash's long term success has been based around the attention to detail, designing elegant product solutions to meet discerning customer requirements around quality and durability, backed by market leading manufacturing facilities and very experienced capable people in the delivery team.


Product Features
 

  • 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 product range which can be fitted with awning, casement, hopper, spinner (i.e. reversible) sliding sashes and doors, all within the same frame design.

  • Sashes are mitred and crimped or cleated to provide superior torsional strength, enabling large sashes to be provided.

  • 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 application 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. 

Frame Size

  • Fixed window frames - 41mm (non seismic) 61mm (seismic).

  • Awning / sliding / hopper / spinner window inserts - 30mm.

  • Hinged doors - 47mm. 

  • Bifold doors - 47mm. 

All windows and doors are interchangeable - Refer drawing details for correct set outs, rebates and flashing details etc.

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.
