Formerly known as Marley Thrutone.
Our slates are usually delivered on a Six Wheeled Lorry (11m Long & 2.4m Wide) with a Tail-Lift facility to off-load on solid level ground with a Pump Truck.
Non compliance to delivery restrictions may result in additional Delivery Charges.
Should you specifically require Crane Off-Load or small vehicle please notify us at the time of ordering, as an additional charge may be incurred.
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 fibre cement slate offers superb aesthetics and with their light weight, low wastage, design flexibility and easy of installation, it's easy to see why they are the 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.
Etex's fibre cement slates are the only such slates manufactures in the UK and can achieve an A+ (the lowest environmental impact) in the BRE's Green Guide to Specification*.

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 is in the following format:
Example: NT UG21WB 24/11/11 12.10 CE.
NT = Type of Product (ie. Non asbestos technology).
UG21 = Product code.
W = Manufacturing plant ID.
B = Class (for bending moment).
24/11/11 = Date of manufacture.
12.10 = Time of manufacture.
CE = CE Mark.
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:
Consideration should be given to sealing any cut edges to prevent potential efflorescence staining.
