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.

The popular Birkdale fibre cement slate can be used for low pitch designs down to 15° (with hook fixing)* offering the designer and contractor more flexible aesthetic and installation options.

The hook fixing method is specifically for 15° - 20° pitches for moderate exposure roofs. This complements our Birkdale range using conventional nail and rivet fixing for steeper pitches or for severe exposure roofs.

Featuring a smooth surface and dressed edges Birkdale fibre cement slates offer a traditional and pleasing look at an affordable price.

The combination of colour, edge finish and design flexibility that the Birkdale offers means it is ideal as both a roofing and cladding solution, used on numerous projects including the Tally Ho training centre in Birmingham and the Holcombe Moor Army base near Bury.

* Fully tested for weathertightness in accordance with CEN TR 15601 standard and subject to exposure category and rafter length
