- Practical and Hard Wearing
- Unaffected by extremes of temperature
- Resistant to moss and mould growth
- Resistant to Insect attack and rot
Natural Slates offer a traditional, effective and attractive alternative to tiles and now, due to a wide selection of imported varieties, offer financial benefits over the long standing traditional “Welsh Slate”, enabling this product to be more widely specified throughout the building industry. Available in a variety of sizes and natural colours.
Alternatives to the traditional slate now come in two main categories;
Re constituted Slate, formed from thermo-setting plastic and recycled slate which benefits from modern materials and fixing technology; this can be especially relevant where ventilation products need incorporation within the roof covering and: -
Fibre re-enforced cement which offer, in some cases, the traditional looks of natural slating, at a reduced cost, enabling this product to be more widely specified throughout the building industry.
All forms of slate are generally secured with smooth shanked copper nails to tanalised, 50 x 25 mm timber battens over a ventilating / sarking felt.
