Kalzip standing seam system comprising of aluminium outer skin, E-clips and tophats with lightweight non-combustible insulation, vapour control layer and an inner trapezoidal liner sheet over purlins.
Application
Aluminium Standing Seam system for roof and wall applications.
Description
Kalzip standing seam and metal liner roof system, with a thermal transmittance (U-value) designed to suit the project requirements.
The Kalzip liner roof system is ideal where speed of installation on a project is of utmost importance. A non-fragile walkable Kalzip liner sheet can be quickly installed to provide a weather cover to allow other trades to work below. The remainder of the roofing components can then be installed without affecting the critical path of the construction program.
The Kalzip standing seam roof sheets are supported directly off the roof purlins via the support clips/ halters (aluminium clips or E clips) so therefore act independently of the Kalzip liner sheet.
When lightweight quilt type insulation is used, the external loads (wind suction, snow, access etc.) are transferred direct to the support purlins and not the liner sheet.
Kalzip liners are available as standard in high grade steel or aluminium. Standard finishes include a galvanized, or white enamel finish to suit the internal application. A full range of alternative colours and coatings is also available on request.
All work undertaken should be fully in accordance with Kalzip standard recommendations and by Kalzip approved contractors.
Kalzip sheets to be installed as per cladding manufacturer's instructions.
Features and benefits:
- The Kalzip liner roof system has the outer Kalzip standing seam roof sheet and the internal Kalzip liner trapezoidal profiled liner sheet laid in the same direction across roof purlins, acting as the primary support. Typical purlin centres would be approximately 1.4–1.8 m.
- A non-fragile walkable Kalzip liner sheet can be quickly installed to provide a weather cover for those working below. The remainder of the roofing components can then be installed without affecting the critical path of the construction programme.
- Suitable for a wide range of applications.
