STRUCTURE
Aluminium side profiles to BS1474. One main bar and one secondary bar which, when linked, behave as one. Both profiles are complete with water-managed systems and are designed to work in a format without seals. Available in mill finish or powder coated white to RAL 9910 BS6496. Other colours are available on request at an additional cost.
A high quality extruded uPVC under-cladding profile clips to the main profile to enhance the thermal properties of the assembly and reduce the possibility of condensation. Fixings must be high quality stainless steel, of a type suitable for the sub-structure to which the panels are
being fixed. Stainless steel greatly reduces the possibility of an electrolytic reaction at the bar/fixing interface.
Xlok Express panel glazing systems can be specified with UV protected 16mm multiwall polycarbonate in clear, bronze and opal tints for solar control.
Xlok Ultra panels are delivered to site with a protective film covering the glazing, which must be removed after installation. Panels should be treated with care. Unloading and manoeuvering is usually easiest by hand. Panels must never be exposed to weather before installation and should be stored in clean, dry conditions, protected against direct sunlight and in an upright position.
Polycarbonate rooflights should only be cleaned with copious amounts of warm soapy water solution and a soft cloth. Never use solvents or alkaline cleaners or thinners. Do not scrub with brushes or sharp instruments, as these will mark the surface. If a rooflight is found to be damaged it must be replaced.
