CUPA – World Leader in Natural Slate

CUPA, Natural Value Company• CUPA PIZARRAS is the natural slate division of CUPA, a company with more than

100 years experience in the slate industry, international leader in slate production and in the development of more energy-efficient building solutions to promote the use of natural slate.

• Our main objective is to respond successfully to an ever-growing demand for natural slate

• CUPA PIZARRAS owns 16 quarries, and 22 factories, extracting 140,000 tons of slate each year and comprises a workforce in excess of 2000.

CUPA, NATURAL SLATE

CUPA’s corporate headquarters, Spain

At the end of this course, participants will be able to:

1. Know how roofing slate is produced… From the quarry to the roof…

2. Identify slate quality and detect potential problems. What do you need to ask when using slate in a project?

3. Know about ventilated facade systems with Natural Slate… CUPACLAD from a technical and practical point of view.

4. Know the only invisible Thermal Solar Panel with Natural Slate… Innovation, Performance & Tradition.

Learning Objectives

Vermont Slate Co – US Leader in Natural Slate

1. NATURAL SLATENATURE’S ROOFING MATERIAL

- A smooth, fine-grained metamorphic rock that can be split into layers- Formed under great pressure and heat starting 400-500 million years ago- Made up of inert materials such as silicates, quartz and mica- Natural, beautiful, colors and shades vary- Resistant to heat, cold, sunlight and acid rainfall. Non-porous- Most slate roofs should last 100 years or more- Low maintenance costs- Environmentally friendly

Natural Slate - Characteristics

90% of the slate sold in the world is Spanish

France 50%

Belgium 4%

Others 8% (Incl. USA)

Germany 18%

UK 20%

Natural Slate - Demand

Before Quarrying…

• Overburden. Sometimes hundreds of feet thick.

• Geological surveys are carried out to find out the best areas.

• Extraction begins only when the quality of the slate rock has been verified.

Natural Slate – How it is produced

• Generally slate is surface quarried but occasionally it is mined.

• Firstly, the ‘overburden’ (fragmented, unusable material) is removed

• The slate is then sawn from the quarry face in large flat slabs using a diamond beaded steel cable

Quarrying… Natural Slate – How it is produced

• The quarried blocks are then transported to factory adjacent to the quarry

• The large slabs are inspected, sorted and sawn across their natural ‘cleavage’ planes into smaller blocks

Factory Sawing… Natural Slate – How it is produced

• These blocks are then hand split by skilled craftsmen into slates of the finished thickness


• The edges of each slate are then “dressed” to give the traditional chamfered edge and exact finished size.


• The slates undergo final inspection and sorting• They are then counted, bar-coded and labelled• Finally the finished slates are packed vertically in crates for transportation and

shipment

Final Inspection & Packing… Natural Slate – How it is produced

• Natural slate can have a widely varying chemical and mineral composition

• Its composition is determined by the geology of the quarry.

• Iron pyrites: Stable and unstable

Natural Slate – Composition

Comparison of French - British - European Standards

• CUPA employs quality assurance procedures under a system approved to ISO 9001: 2000

• Each quarry has quality approval from the National Laboratories of its customer countries

• CUPA has its own laboratories on site

Natural Slate – Quality Control

Each crate of CUPA slate has its own label, which holds all the information an end user might need to know about the origin of the slate, the slate type, its dimensions and test results. The bar coding gives further information about where and when it was processed and even who worked on that particular batch.

Natural Slate – Traceability

• Unstable Iron Pyrites • Water absorption too high• Breaking strength too low• Pre-existing de-lamination• Calcium carbonate content

too high

Characteristics of poor quality roofing slate

• Ask for evidence of recent test certification, preferably to French Standard P32301, showing date, name and origin of slate

• Are sufficient stocks available for duration of project?

• Traceability- Is the slate arriving on site what you specified?

A check-list for problem-free slate specification

• Cupa Natural Slate, great focus in sustainability

• Cupa is the only Natural Slate that has achieved an A+

• Rating for the lowest environmental impact in the BRE Green Guide to Specification

Bond/side laptailExposure

The nail hole should be approx. ¾”-1 ¼”from the edge of the slate. Distance from top depends on slate length. For ex. 4 ½” on a slate 16” long The nail hole should be made from the underside of the slate.Proper head lap depends on pitch. Should be 3” at least.

Fixing Terminology

The position of the nail holes is dependent on the pitch (angle) of the roof and the site exposure.

At lower pitches or in exposed situations slates must overlap more to resist wind driven rain.

2.1. CUPACLAD – VENTILATED FAÇADE SYSTEMS WITH NATURAL SLATE

New solutions with Natural Slate…

Ventilated façade systems with natural slate

New solutions with Natural Slate…c

VENTILATED FAÇADE. Main advantages Chimney effect Reduction of condensations and humidity; and

elimination of filtration of rainwater.

Reduction of structural movements and cracks in the building

Energy saving and thermal comfort, thanks to the cooling of the building in the summer, and the control of thermal dispersion in the winter.

Increase the durability of the cladding


3 DIFFERENT VENTILATED FAÇADE SYSTEMS

Traditional installation… - CUPACLAD 301

New solutions… - CUPACLAD 101: Invisible system - CUPACLAD 201: Visible system


CUPACLAD 301

CUPACLAD 301- All avaliable slate formats in CUPA range

CUPACLAD 301

-Tradicional way of installation with triple lap. This makes the facade fully waterproof.

- The fixings can be visible or invisible

- The installation of this system must be performed by a specialist in slate roofing.
