INTRODUCTION

The Delta commercial suite was designed and introduced to the New Zealand market by Thermosash nearly twenty five years ago. Today, it is recognised as the market leader, having been specified and incorporated on the great majority of New Zealand's noteworthy projects where product quality and long- term high performance levels are required.

This suite has been used extensively on major export projects around the Pacific Basin. Middle East and Asian markets. It is manufactured under licence in South Africa by Wispeco, the largest manufacturer/contractor in this continent (references available upon request).

PRODUCT FEATURES O An extremely versatile product - outer frame con-

struction, 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.

O 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.

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

O Sashes are designed with pressure seals internally (rear airseal) and externally to the heads and jambs (rainscreen) to provide high performance rainscreen pressure equalised weathering

O Sashes have an integral drainage channel in the web of the section eliminating the need for externally applied weatherbars

O The system is generally dry glazed with high quality Santoprene gaskets

O 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

O Delta windows can accommodate virtually any thickness of glass or panel from 4mm to 28mm

O 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.

O Specifically designed extruded sill trays are provided on all product 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. 1 This provides the specifier and his client with peace of mind that the installed product will perform long-term - well after ; the guarantee period has expired.

O Wide range of mullions and transoms enabling custom built window systems to comply with specified strength/ deflection requirements

O The suite incorporates locate, snap-in glazing beads to all window and sash sections which enables fast and efficient glazing/reglazing

O Delta commercial window sections integrate with our Montana Residential product range for high quality custom residential window applications
