Rivendale fibre cement roof slate features a riven surface and dressed edge, combining the benefit of modern slate technology with the look of natural slate.

Ideal for use on projects where a natural look is sought, the Rivendale has been used on a number of projects, where sustainability is high priority, including Hawkshaw Lodge by Cambrian Homes, in a green belt conservation area near Bury and the Altrieswood Development by Churchill Homes in Scotland.

Notes

Fibre cement slates meet the strength requirements of BS EN 492, achieving an average bending moment greater than 50Nm/m (Class B). The slates also have a minimum density of 1700kg/m³ and a nominal thickness of 4mm. 

The batch code printed onto the underside of the slates or slate fittings is in one or the following formats:

Example 1: NT UG21WB 24/11/11 12.10 CE

NT = Type of product (ie. Non asbestos technology)

UG21 = Product code

W = Factory of origin code

B = Class (for bending moment)

24/11/11 = Date of manufacture dd/mm/yy

12.10 = Time of manufacture

CE = CE Mark

Example 2: T 2 14 20 C1 NT

T = Factory of origin code

2 = An internal factory coding

14 = Year of manufacture

20 = Week number of manufacture

C1 = Shift of manufacture and  product type

NT = Type of product (ie. Non asbestos technology)


Example 3: CE 7 B 13 112 X NT 11:12

CE = CE Mark

7 = Factory of origin code

B = Class B (Note This may or may not be present)

13 = Year of manufacture

112 = day N° of manufacture

X = Shift (X,Y,Z)

NT = Type of Product (ie. Non asbestos technology)

11:12 = Time


Example 4:   (fittings) 14.01.14  20  &  CE M NT  &  O

14.01.14 = Date of manufacture dd.mm.yy

20 = Roof pitch (degrees)

CE = CE mark

M = Factory of origin code

NT = Type of product (ie. Non asbestos technology)

O = Internal factory code


The effectiveness of the tile or slate to operate at the minimum recommended pitch and lap may be influenced by special circumstances. Guidance on pitch and lap should be obtained from the Technical Advisory Service for the following:


• Interlocking tiles and slates where the roof slope exceeds 6 metres in length and/or the site is rated to be in a severe exposure category.
• Double-lap fibre cement slates where the roof slope exceeds 6 metres in length (severe/very severe exposure) and 9 metres in length (sheltered/moderate exposure).

Note: Consideration should be given to sealing any cut edges to prevent potential efflorescence staining. Contact TAS for further details.
