Intruder windows

Designed for use as fixed lights and open out windows. Internally beaded options are available for use in conjunction with Smart Systems Visoline framework. Suitable for domestic and light, medium and heavy commercial applications.

Windows are manufactured according to customer requirements from a range of standard profiles, and are designed to incorporate a range of vent openings and various options.

The windows incorporate an internal pressure equalized drainage system, with concealed down drainage through a sub sill or frontal drainage with snap on cover caps.

The outer frame is 51 mm deep, with two 18.5 mm thermal break sections within the window profiles. Joints between frame members are formed by 45º mitred corners, reinforced with extruded Aluminium cleats and Stainless Steel corner braces and secured either by gluing and crimping or gluing and corner cleats. Mullions and transoms are secured using either stainless steel Screws driven into integral screw ports within the sections, or cruciform cleats. All joints are sealed during construction.

Performance:

Product tested to BS 6375-1. Weather tightness classification:
_Air permeability – Class C.
_Water tightness – 600 Pa.
_Wind resistance – 2400 Pa.


Structural profiles are designed so that maximum deflection of any Glass edge into a member under windload will not exceed 1/175 of the span, with no permanent deformation. Horizontal framing members will restrict deadload deflection to 1/400 of span, up to a maximum of 3 mm.

Fixing:

Fixings must ensure the window is retained securely within the opening without damage or distortion to the window frame. Generally, fasteners should be positioned 150 mm from each corner and each mullion/ transom, and at centres not exceeding 600 mm.
