"A revolutionary roofing system for agricultural and utility buildings with built-in moisture management"
What is it ?:
High performance polyster pre-painted steel, with a heat coated reverse of unwoven fabric.
How does it work ?:
Humidity is absorbed by the fabric and evaporates later when the temperature rises.
Further Features;?:
The use of DRI-CLAD does not exclude, under any circumstances, the natural ventilation of roof space.

SHEET LAYING GUIDE FOR DRI-CLAD
In order to ensure a watertight skin to the building, it is essential that the correct installation and fixing procedures are followed. To prevent the ingress of driving rain, side laps should be sealed and face away from the prevailing wind. In all cladding applications adequate end lap is critical. For roofing applications, the end lap is largely dependent upon the roof pitch. Please refer to the table below for guidance.
ILLUSTRATION: SEQUENCE OF LAYING
FIXING
Primary fasteners should be fixed through the centre of every other valley at each purlin, except at end laps where fasteners should be placed in every valley. All holes should be drilled and not punched and resultant swarf removed.
It is important to ensure that correct tightening torque is applied to the fastener to obtain maximum sealing and holding action. The above details are based upon experience, however sheeting contractors may adopt their own fixing methods but the Health and Safety Executive requirements must be satisfied.
