Cladding
Standing seam
Standing seam roofing has become an established style over the last decade. First seen on large retail units the system is now often seen on smaller, centrally located new builds. Often specified because of its contemporary design possibilities, unlike a traditional pitched roof each sheet is fixed to the buildings structure in one length omitting the laps between sheets that are usually found upon composite or twinskin roofs.

Often specified because of its contemporary design possibilities, unlike a traditional pitched roof each sheet is fixed to the buildings structure in one length omitting the laps between sheets that are usually found upon composite or twinskin roofs.
Curved roofs constructed using the standing seam method are fixed in the same way as built up systems. An internal liner is fixed in place first, followed by bars and support brackets. The design of the laps allows the fixings to be hidden, combined with a non ferrous material for the top sheet this form of roof is often considered leak and corrosion proof. Sheeting is rolled from the coil on site in single continuous lengths from a container that is craned to roof level
Composite panels
Composite panels consist of three layers. The top sheet is the surface of the roof, the second layer is insulation and the liner sheet which is seen from inside the building once the sheeting is fixed in place.
Building regulations allow for an 80mm standard panel to offer sufficient thermal efficiency for a building which is measured as a U-value. A 60-70mm panel offers adequate U-values for the sides or cladding of a new building depending upon the specific design requirements for the cladding. Wall cladding can consist of various panel types that offer different profiles, colours, finishes and styles.
Built up twin skin
An alternative to composite panelling for new-builds is a twinskin or built-up system of cladding. The method of fixing the individual roof components allows for flexibility and diversity within the design of the roof or wall cladding. This system can be used in the same way as composite panelling with the correct thickness of insulation to achieve the required thermal efficiency.

Liner sheets can vary in design for different projects i.e perforated liners for sound absorbtion or thicker sheets to allow personel to traffic across roofs prior to completion. Aluminium or coated steel topsheets can be fixed above the insulation and liner panels to match almost any specification.
As well as being suitable for new builds the system offer flexibility for refurbishments and repair works that will offer an existing roof another 20-25 years of life with no real impact upon the clients business.
