Roofing & Cladding Information
The choice of cladding is generally dependent upon building specification insulation requirements, building use, Geo location of building and \ or budgetry requirements.
All systems are available in a range of colour coated sheet profiles with the most popular being Trapezoidal & Microrib – other profiles can be supplied if required.
Panels can be supplied in a variety of paint finishes and colours, samples of which are shown below:
Note * light colours are better in hot countries to restrict solar gain (Download our ventilation Guide)
The following is a brief guide to our standard roof and wall cladding systems – we’d be pleased to offer you any advice or assistance in specifying your requirements – Just call +44 1202 483 333
As the name implies, this system consists of a single Trapezoidal profile sheet fixed over roof purlins or wall side-rails – Fixings are generally through the trough and sheet thicknesses are typically 0.5 – 0.7mm depending upon application.
Typical applications would be aircraft hangars, warehouses, storage Buildings, Stadia Canopies etc. – especially for buildings in hot climates.
For single skin systems in cooler climates a special fleece lined profile is recommended to trap condensation and prevent dripping inside the building.
A liner sheet is first affixed to the purlins \ side rails before a galvanised spacer system (sized to suit insulation thickness) is installed.
Fibreglass insulation is then cut and tucked around the spacer bars.
Finally the outer cladding is laid over the insulation and attached to the spacer bar system.
Built up double skin systems are the ideal choice where higher levels of accoustic and noise reduction are required.
2 hour & 4 hour boundary fire wall systems are available in double skin installations.
With this system the inner liner panel has been factory bonded to the external profile panel with a core of high performance insulating material (of varying thicknesses) that is fire retardent and forms an airtight, condensation free system.
Composite panels are generally fixed directly to roof purlins or wall sidebars via secret-fix fastenings allowing rapid installation with an architecturally pleasing finish.
Wall panels can be fitted both horizontally and vertically and panels can be manufactured to order in various lengths and widths for precise fitting.
Roof pitch and curvature would typically dictate profile choices – Shallow pitch roofs down to 1.5 degrees or low curvature roofs would generally use standing seam profile, whilst higher pitches favour trapezoidal profiles.
Microrib profile is usually specified for both vertical and horizontal wall cladding applications and offers a pleasing, less industrialised look that compliments modern building design
These panels achieve similar results to the built up standing seam aluminium roof system in that they are also “zipped” in situ to form a watertight seal with no through panel penetrations – However they are manufactured in coated steel instead.
Built up Roofing – On site Standing Seam Production
For eaves to eaves or gable to gable long run standing seam production, profiles can be formed on site from aluminium strip (600mm wide) using specialist machinery and equipment.
Production is often carried out at eaves height and can also include the formation of continuous curves.
