Cembrit, the leading roofing and cladding specialist is proud to announce the addition of two new sizes to its Glendyne range of natural slates, 60x30 and 50x30, offering roofers larger slates and more versatility when working on lower pitched roofs. On a roof with a lower pitch, the large size of the slates will not let water sit between the slates and prevents the water from getting through. Larger slates work well on low pitched roofs and are best suited for use in coastal areas where the environment has a greater degree of moisture content.
The larger sized Glendyne natural slates, 60x30 and 50x30, can be pitched at a minimum of 25° and 20° in moderate exposure zones and 30° and 22.5° in sever exposure zones respectively. The slates exceed the common 2:1 length width ratio, allowing for specification on greater range of roof pitches. The range offers a quality alternative to Welsh Slate and is readily available. Cembrit also has the facility to examine individual cases and offer specific advice on minimum pitch per project outside the parameters of BS 5534.
Glendyne is a high quality slate that combines first-class performance with all the inherent beauty of natural slate, making it the ideal ‘natural’ choice for specifiers and roofers. Available exclusively from Cembrit in the UK, Glendyne is a distinctive blue-grey colour. The Glendyne quarry is one of the most modern slate quarries in the world. The quarry operates a quality management system based on EN ISO 9001 which is externally audited.
This standard is adhered to rigidly, as are all quality standard procedures required by each regional market the quarry supplies. Glendyne, like all natural slate from Cembrit, is tested to BS EN European standard, BS EN 12326-1:2014 which requires many of the laboratory tests (‘type testing’) to be performed at least annually and the factory production control (FPC) performed and recorded as a matter of routine by the producer.
