Canadian Glendyne Preholed Natural Roof Slates 20 inch x 15 inch 500mm x 375mm

Glendyne Canadian slate is produced in the town of Saint Marc du Lac Long, Quebec, Canada.

Produced from deposits laid down in the Ordovician era some 500 million years ago this quarry was first opened by British slate quarrymen in the early part of the 20th century. Roofs with Glendyne slate can still be seen today around the area of the quarries, some 90 years later.

These are a good match for Ffestiniog or other blue/grey British natural slate offering consistent high quality, high strength & minimal unstable mineral content.

Glendyne slate has a reputation for quality due to the exceptional slate deposit and the combination of modern extraction methods with traditional finishing skills.

Fixing
Fixing
  • Slates should be twice centrenailed to horizontal battens etc., as described in BS 5534, using copper, aluminium, phosphor or silicon bronze nails to BS 5534: 2003
  • The minimum head diameter for nails used with natural slates is 10mm (which generally means a shank diameter of between 3.00 - 3.35mm) and they should penetrate into the batten by a minimum of 15mm
  • Slates, generally, should be not less than 150mm wide
  • At all verges and abutments, alternate slate courses must start with half width or slate and half width to maintain bond.
  • Slate and a half widths must be used if the half slate is less than 150mm wide
  • At valleys and hips where slates need to be cut on the rake, wide slates must be used to maintain an adequate width at the head or tail
  • At mitred hips on low pitched roofs wide slates should be used beneath the hip capping.
