Specification System 6 The Metal Technology Thermally-Broken Vertical Slide Window has been designed in such a way that its'attractive and clean lines will enhance all types of residential and commercial property. Various other profiles have been designed and incorporated allowing architects to achieve combinations of fixed lights and sliding sashes without the need for a seperate coupling mullion. Introduction The system can accommodate both 6mm single glazed and 24mm double glazed units. As with all Metal Technology systems, the vertical sliding window system is manufactured to exacting standards enabling economy to be combined with strength to give many years of aesthetic, trouble-free operation. Scope This specification defines materials, construction, finishes and size limits for vertical sliding windows. Materials Aluminium profiles are extruded from aluminium alloy 6060T6, T5 or T4 complying with the recommendations of BS1474. Where sections have a thermal break, this is polyurethane. Finishes The range of sections can be provided in either of the following ranges of finishes: 1. Anodised to BS1615 or BS3987 2. Powder organic coated to BS6496 Construction Frame members are generally square cut (jamb bars have a 5 mitre at the bottom). Corners are assembled with stainless steel screws driven into grooves in the sections. All frame joints are sealed during construction against entry of water. Woven woolpiles and glazing gaskets are provided to resist the ingress of water. Glazing Wrap-around "U" gaskets are fitted around the glass and then the sash frames are assembled around the glass. Installation Detailed installation instructions are provided which should be strictly followed. Vertical Slide Fittings Sliding sashes are designed to be hung on spiral spring balances. These are designed to support the sash in any designated opening position. At the meeting rail the sashes are secured by means of a sash lock and keep. On windows over 1000mm wide two sash locks and keeps should be fitted. Size Limits Size limits are generally dictated by the weight of the sash, however as a general principal none of the following limits should be exceeded. (Where a window is close to any of the maximum limits Metal Technology should be consulted.) Max Window Width 1500mm Max Window Height 2500mm Max Sash Weight 43 Kg Performance All windows are designed to provide Class ll weather tightness as defined by BS6375 pt.1 and BS4873. Should increased performance be required a deeper cill and bottom rail are available. Please consult our sales desk for information. Development Our policy is to continually research the market for new and improved products. We must therefore retain the right to amend specifications without prior notice. It is recognised at Metal Technology that in some instances special sections may be required for particular projects. When this occurs it may be possible to produce special sections subject to there being sufficient quantity and adequate time.
