Authority BS EN 492
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). 
 
Consideration should be given to sealing any cut edges to prevent potential efflorescence staining. Contact Technical Advisory Service for further details.The discharge of rainwater from the gutters and downpipes, from one roof to a low pitch fibre cement roof(15° max. 4m rafter length) is not recommend and should not be specified. Skylight roof windows and other penetrations should not be specified or constructed with a low pitch fibre cement roof(15° max. 4m rafter length).

Thrutone fibre cement slate

A smooth surface and square cut edges give a low profile slate at an economical price, particularly suitable to complex roof geometries down to 15°. This market leading light weight roof slate is now available in five new colours and three shapes providing even more design flexibility.  With its low wastage and ease of installation, it's easy to see why it is the product of choice for all types of new build and refurbishment projects. 

Used on a variety of applications, Thrutones provide the flexibility to create inspirational roofs and facades, examples include Canon Popham School in Sheffield and the stunning curved roof of the Cavell Centre in Peterborough.
