  • Low maintenance solution
  • Does not rust, rot or corrode
  • Resistant to chemical attack
  • Excellent noise and thermal insulation

Marley Roofing’s Super 6 roof sheets are carefully developed for a variety of needs that can be used in both roof and cladding solutions. It is widely recognised in the market for applications in the commercial, residential, agricultural and industrial sectors.

Our product is manufactured according to strict international standards:  ISO 14001; ISO 9001 and OSHAS 18001 and complies with South African standard SANS 10904 product specifications.

Super 6 is a high strength, fibre cement corrugated roof sheet and has a very broad appeal. It is designed for roofs at a 10 degree pitch, 5 degree pitch specifications are available on request.  

It is well suited for use in a vertical cladding application - both single skin and insulated constructions.

Properties

Impact resistance
The test for fragility of roofing assemblies’ ACR (M) 001: 2005 consists of a 45kg bag being dropped from a height of 1200mm onto a fixed sample of roofing. It is intended to provide information about whether the roof can support the instantaneous loads imposed on it by persons stumbling or falling onto it. A roof is classified as fragile if the bag passes through the roof assembly.

If the bag is retained on the test assembly and no other drop tests are carried out, the assembly shall be classified as Class C non-fragile assembly. Marley Super 6 sheets meet this requirement.

Sound insulation
When tested in the critical frequency range of 100-3150Hz, Marley Super 6 profiled sheeting achieves the following mean airborne sound reduction:
Single skin 26 decibels

Breaking Load
Marley Super 6 complies with EU standard of 3.5kN/m

Installed weight
The approximate installed dry weight of single and double skin profiled sheeting with fixings and the required side and end lap: 17.0kg/m²

Fire
Marley Super 6 roof sheets are non-combustible (category A1 of Fire classification) and do not explode at high temperatures.

Water tightness
Marley Super 6 roof sheets complies with SANS 10409.

Moisture content
When new, fibre cement sheeting has a relatively high moisture content. If humid conditions prevail, damp patches (without formulation of droplets) may appear on the underside of the sheets. This phenomenon is in no way detrimental to performance, and will disappear within 12 months, in the course of natural exposure.

Condensation control
Whilst Marley Super 6 is watertight, it has the ability to absorb up to 25% of its dry weight in moisture and dissipate it in more favourable conditions. This material characteristic has a significant effect in reducing condensation occurrence.

Effects of chemicals
Over the years chemical and industrial atmospheric pollution will cause a slight softening of the surface of natural finish fibre cement sheets. The acrylic paint finish provides added protection against many acids, alkalis and solvents normally found in the atmosphere.

Where fibre cement is to be used in particularly aggressive atmospheres, with higher than normal concentrations of acids, alkali's, fats or salts, please contact us for advice.

Biological
Marley Super 6 sheets are vermin and rot-resistant. Lichen may grow on the outer surface of the boards, this will not diminish the integrity of the board and can be cleaned off with copper sulfate.

Effects of low and high temperature
Marley Super 6 roof sheets are designed to be minimally affected by frost or climatic temperature changes.

For buildings in which higher than normal temperatures occur, or in areas which are expected to be subjected to sudden changes in temperature, special considerations may be necessary. Contact us for further recommendations and guidance.

Thermal and other movements
The amount of movement is negligible, but it is necessary to provide movement joints in association with the structural framework. The co-efficient of linear expansion for profiled sheeting is 8 x 10-6m/mK.  Please adhere to the professional designer's recommendations.

Thermal conductivity
Marley Super 6 has a low thermal conductivity when compared with other sheet roofing products. This serves to reduce heat build up in summer and heat loss in winter.
Thermal conductivity (k) = 0.48W/mK.
