Duraclad® is a heavy weight premium grade glass fibre reinforced polyester sheet profiled for use as roofing and wall cladding. It is available with a choice of surface finishes and resin types to provide maximum durability in specific environments.
*The specific chemical nature of the environment must be discussed with Dimond to ensure the correct resin type is chosen. Duraclad is available in a range of colours. Please contact 0800 DIMOND.
Standard material thickness is 1.7mm (nominal). Duraclad® is available in thicker sheets if required.
Features and Benefits
- Non corrosive substrate and surface protection provides excellent durability in harsh environments.
- Available in continuous lengths limited only by transport, handling and installation considerations.
- Proven durability in buildings with uses like wool scouring, fertiliser storage, exposure to severe marine or geothermal activity, galvanising and battery acid plants, swimming pool covers.
- Suitable for service temperatures of –10ºC to 50ºC.
- Available in the following Dimond range of roofing and wall cladding profiles: Corrugate, VeedekTM / Styleline, V-Rib, LT7, BB900, SS900, Super Six.
Limitations of Use
Duraclad® will support combustion and require fire engineering input if intended for use where fire ratings are required.
Not intended to support foot traffic other than carefully placed foot point loads on purlin lines during installation.
Fastener corrosion may require fastener replacement before Duraclad® requires replacing.
Will require the installation of Safety Mesh under the sheeting when used as roofing on spans that exceed the scope of the load span data given in section 2.1.4 of Technical Manual for each profile. Safety mesh should be used whenever foot traffic is expected. Whenever mesh is used under Duraclad®, a separation layer such as Dimond purlin protection strip, must be placed between the mesh and the Duraclad® to protect the sheet underside.
Keep surfaces clean by regular washing.
Inspect fasteners, and replace before corrosion becomes advanced.
Aesthetic value can be restored by over painting the surface with a suitable coating system once the original surface has:
- become well weathered
- lost the top surface.
Do not use abrasive cleaners on Duraclad®.
Handling and Storage
Care must be taken not to damage the surface films. Material should be stored so it will remain dry and not suffer damage.
The correct fastener size for the sheet profile should be used (refer section 2.1.4 of Technical Manual).
The Duraclad® sheet must be pre-drilled with an oversize hole 2mm larger than the diameter of the fixing. When thermal expansion must be allowed for a larger pre-drilled hole diameter will be required. Refer Section 184.108.40.206 of Technical Manual.
The choice of fastener material must take into account the durability expected in the particular environment.
Severe internal environments may require that the screw shank is protected from contact with corrosive materials.
