The Marley Eternit slate rangeThe Marley Eternit slate range provides the charm of

a slated roof with all the economical, functional and

environmentally friendly attributes of modern slate

technology.

Eternit fibre cement slates – light in weight, strong

and durable – closely resemble the natural material

without compromising aesthetics and economy.

The interlocking concrete slate range offers single

lap slating solutions that are quick and easy to install

and replicate the appearance of the natural material.

Both ranges offer durability, versatility and appeal.

Both ranges are complemented by a comprehensive

range of ventilation and dry fix systems, underpinned

by first class Customer and Technical services.

Marley Eternit was the first building materials

manufacturer to be awarded product certificates

under the Environmental Profiles Scheme (BRE).

The Marley Eternit interlocking slate range has an ‘A’

rating indicating the best environmental performance.

AuthorityMarley Eternit concrete roof tiles and slates are

Kitemark certified as being manufactured to the

requirements of BS EN 490. All Marley Eternit

factories operate quality management systems to

BS EN ISO 9001. They also operate environmental

management systems to BS EN ISO 14001,

registered by the BSI.

The appearance of the slated roof has been part of the

built environment since time immemorial.

As well as adorning some of the nation’s most important

historic buildings and being a staple of vernacular

architecture in many parts of the UK, slated roofs are

used increasingly in design-led projects for the commercial,

public, leisure and retail sectors.

Edgemere slates without nail holes should be laid below 25°

rafter pitch and where required, should be clipped. Nail holed

slates should be used at rafter pitches of 45° and above.

Please indicate if slates are required with or without nail holes.

EdgemereA clean and precise slate-like appearance is

enhanced by the thin leading edge and the

broken-bond laying technique.

Edgemere should be laid broken bond. The required

broken bond pattern is created by the introduction of half

slates, to form verges in alternate courses.

Duo EdgemereAn interlocking slate designed to look like and

blend in with small format slates.

Duo Edgemere should be laid broken bond. The required

broken bond pattern is created by the introduction of three

quarter width slates, cut from standard slates on site to form

verge slates in alternate courses.

Measuring environmental success

At Marley Eternit, we were

among the first in the industry

to achieve ISO 14001, the

internationally recognised

environmental management

standard. We were also the

first in the construction industry

to have our LCA (Life Cycle

Assessment) data independently

reviewed and to be awarded

Certified Environmental Profiles

by the BRE (Building Research

Establishment).

Environmental profiles and EcopointsLCA data presented in the form of an

Environmental profile allows architects, builders

and clients to make informed environmental

comparisons between construction products.

To improve the usefulness of this data

further, BRE has developed Ecopoint scoring,

a method of ranking different environmental

impacts.

Ecopoints allow a wide range of environmental

impacts (e.g. energy use and mineral extraction)

to be compared using the same measure.

The lower the Ecopoint score for a product,

the lower the environmental impact. As a

benchmark, it has been determined that 100

Ecopoints are equal to the impact of one UK

citizen on the environment for one year.

A single Ecopoint would be equivalent to, say,

water for 1000 baths or the manufacture of

250 bricks.

Putting Ecopoints in contextBy comparing Ecopoint scores, informed

environmental comparisons can be made

between construction products.

The diagram (right) illustrates the relative

significance of various components of a roof

and illustrates how, for example, interlocking

concrete roof tiles contribute less than 40%

of the total environmental impact of roof

construction.

BREEAM and the Green Guide to SpecificationThe BRE’s Environmental Assessment Method

(BREEAM) is a design and management stage

assessment tool that provides an environmental

label for buildings, based on good practice.

BREEAM is widely used to specify overall

environmental performance. One of the aims of

BREEAM is to encourage the use of materials

that have lower impact on the environment,

taking account of the full life cycle of the

materials in question.

EcoHomes and the GreenGuide to Housing SpecificationEcoHomes is the housing version of BREEAM.

As with BREEAM, one of the aims of

EcoHomes is to encourage the use of

materials with the lowest environmental

impact, taking into account their full life cycle.

Credits are awarded for a range of areas

in each building according to performance.

A set of environmental weightings then enable

the credits to be added to produce a single

overall score.

The building is then rated on a scale of ‘pass’,

‘good’, ‘very good’ or ‘excellent’.

Specifiers are encouraged to consider

these issues at the earliest opportunity to

maximise their chances of achieving a high

BREEAM rating.

The Green Guides to SpecificationThere are two Green Guides available:

• ‘The Green Guide to Specification’,

for commercial buildings

• The ‘Green Guide to Housing Specification’

for homes

Green Guides are books written by the BRE that

enable the reader to assess the environmental

performance of construction specifications

ranging from external walls, roofs and

landscaping to internal elements such as

partitioning, raised floors, insulation and doors.

Green Guides categorise each specification by

converting Ecopoint scores into ‘A’, ‘B’ or ‘C’

ratings. An ‘A’ rating means the least

environmental impact, where a ‘C’ rating

represents the highest level of impact.

The environmental ratings in the Green Guides

are based on LCA studies of environmental

impacts of construction materials. The data

behind these ratings was provided by various

trade associations or was the best available data

on the environmental impacts of construction

materials available at the time of publication.

Green Guides contain generic data on different

construction specifications (i.e. they are not

manufacturer specific).

Assessing the sustainability of buildings

Marley Eternit We are able to use our own independently

certified environmental profiles and Ecopoints to

determine the Green Guide rating of our concrete

tiles and slates, Melbourn interlocking slate and

Eternit fibre cement slates. They all achieve ‘A’

ratings (the lowest environmental impact).

The diagram, left, shows these products within

the Green Guide ratings for 1m2 of a typical

complete roof structure over a 60 year life for

a 35° pitched roof and 1m2 over a 60 year life

for a 50° pitched roof.

In the Green Guide, generic clay plain tiles also

achieve an ‘A’ rating.

Furthermore, the use of Marley Eternit SolarTile

can reduce energy requirements, help reduce

CO2 emissions and can play an important role

in sustainable construction practice.

Due to product changes, improvements andother factors, the Company reserves the right to change orwithdraw information contained herein without prior notice.For specific applications users should refer to the TechnicalAdvisory Service and relevant Standards and Codes ofPractice for guidance.

The photography shown in the document should not necessarily be taken as recommendations of good practice.

The printing process restricts the exact representation ofcolours. For true colour reference, please request productsamples.

For tiles and slates, it is recommended that, to enhance theappearance of the roof, pallet loads are mixed whilst the roofis being loaded.

Efflorescence can occur from time to time in all concreteproducts with a high cement content, but is a temporaryeffect and is not detrimental to the function of the product.Natural weathering will remove the salt deposits that causethis harmless effect.

All Marley Eternit Dry Fix products will have a life comparablewith other components of the roofing system. Componentsmanufactured from PVCu that are subjected to long termexposure to the weather will suffer UV degradation; this maycause fading and a reduction in impact strength although theperformance of the product will remain unaffected.
