Technical Specification Information

Durability/Strength/Permeability

We have independent tests carried out by Cranfield University Shrivenham; and results confirm that durability and strength exceed specifications laid down by British Standards covering concrete roof slates.
To BS EN 491

Weight

90-115 kgs per square metre depending on sizes used.

Estimating

Free estimates will be prepared from drawings or site visits.

Batten Gauges

Batten spacing will diminish up to pitch of the roof; so an accurate rafter length will be taken on site and a batten chart provided on request.

Recommended Underlay

We would recommend you refer to your local building regulations office.

Pitch

The Cotswold 2000 Slate is suitable for use as a weather resistant and decorative covering to conventional timber roofs of over 40 degrees.

Ventilation

Sufficient ventilation must be provided to avoid roof space condensation. Advice can be obtained from your local building control office.

Delivery

Over the years we have found pallets to be very troublesome for many reasons, we therefor deliver and stack the slates on site; in height sizes, enabling quick and easy access for the roofer.

Quantities

Given so many varying sizes of slates, it is inevitable that a selection of spare sizes will be required, we therefore supply slightly more to allow for slight variations. Once the roof is complete we will organise the collection of any left over slates.
