Overview
Ventilation louvres can be applied to Profarm, Procolor and Proclad to allow airflow. Both the 1000 mm and 800 mm cover widths can be vented.
Mainufacturing Details
The diagram below illustrates some of the capabilities and limitations in relation to venting.
Standard Vented Area
Unless indicated otherwise at time of order the maximum possible area of the sheet will be ventilated, i.e. venting will start 100 mm from top and extend to 200 mm from bottom with vents spaced at 40 mm.
Available Lengths
Maximum length: 6 m
Minimum length: 610 mm
Ventilated sheets are available ex stock in ProFarm only as indicated below:
| Sheeting type | Cover width (mm) | Colour | Thickness (mm) | Stocked lengths |
|---|---|---|---|---|
| Profarm | 1000 | Juniper Green Slate Grey |
0.55 | 1.219 m (4’) 1.524 m (5’) 1.676 m (5.5’) 1.829 m (6’) 2.134 m (7’) 2.438 m (8’) |
DPC Barrier
To prevent corrosion a DPC barrier must be used when steel cladding is fixed to wet, green or treated timber purlins.
Packing, delivery and storage
All deliveries, unless indicated otherwise, are by road transport with packaging to suit land delivery. As a general guide pack sizes are limited to two tonnes and the entire pack is wrapped in polythene. Offloading is the responsibility of the client. Water ingress between sheets will have a negative effect on the performance of the sheet. Wrapping is only a temporary protection for transport purposes and is not suitable for outdoor storage.
