Note: This is a variation of Corrugated Fiber Cement Boards.

Non-combustible corrugated fiber cement boards. Profile 3, Profile 6, and Profile-8 are differentiated by the size of corrugation in the sheets; Profile 3 having the smallest corrugations, Profile-8 in the middle, and Profile-6 having the largest corrugations. All 3 sheets are manufactured from a selected blend of Portland cement and water, while being reinforced with a mixture of both natural and synthetic fibers. Corrugated fiber cement boards offer the following benefits for roofing or siding:

  • Highly cost effective weatherproofing
  • Virtually maintenance free
  • No rust, rot or corrosion
  • Resistant to chemical attack
  • Vapour permeability reduces condensation
  • Excellent noise and thermal insulation
  • Quick and easy to install and fix
  • Wide product and color range

Profile 3 and Profile 6
Marley Eternit, the Country’s largest manufacturer of fibre cement products, has been producing profiled sheeting for over 90 years. Today, we offer two ranges of profiled sheeting – Profile 3 and Profile 6 – to a wide range of customers. The products are differentiated by the size of corrugation in the sheets; Profile 3 having smaller corrugations than Profile 6.
Both types of sheet are manufactured from a selected blend of Portland cement and water. This is reinforced with a mixture of both natural and synthetic fibres. The longevity of this formulation has enabled Marley Eternit to offer a 30 year guarantee on our sheets and fittings (available on request).
Marley Eternit have always worked to improve safety when using our range of roofing and cladding products. Building upon over 90 years experience in the UK roofing industry we have developed a purpose designed, reinforced fibre cement sheet – Profile 6 – that meets the high standards of safety in roofing work set out in the Health and Safety Executive document ‘Health and Safety in Roof Work’ (HSG 33). In addition to the Profile 6 sheet, we are proud to be able to offer a complementary range of accessories that meet the same high standards of safety.
Eternit fibre cement profiled sheeting is manufactured in accordance with a quality system registered under BS EN ISO 9001. They also hold British Board of Agrément Certificate No. 00/3700.

Other products
In order to ensure full compliance with HSG 33, ridges and rooflights must also be upgraded. Marley Eternit can supply a full range of fittings to ensure that the complete roof is non-fragile

Additional Information

Profile 6 and safety in roof work
When correctly installed, Profile 6 has been tested and classified as non- fragile, and must be considered when working to the roof safety requirements of HSG 33. In addition, Profile 6 has also passed the French and Danish standards with flying colours.
Profile 6 is a high strength fibre cement sheet with polypropylene reinforcement strips inserted along precisely engineered locations which run for the full length of the sheet in each corrugation. This provides maximum reinforcement strength with no loss of durability in service.

Which Profile?

The decision to use Profile 3 or Profile 6 sheets will depend largely upon the following four criteria:

1. The scale of the building in question.
2. Compatibility with any existing materials.
3. The distance from centre to centre of the horizontal fixing railsor purlins.
4. Whether or not the roofing material is to be classified as non-fragile.

Reference should therefore be made to the sheet sizes, fixing detailsand product data provided in this leaflet before deciding which type ofprofiled sheeting to use.
