Delta Commercial Heavy Duty Window Suite

Delta 600 - Low / High Rise - Butt glazed vertical, mechanically engaged horizontally

• 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 high rise application from within the building, removing the need for costly external scaffolding.
• 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.
