Cembrit has announced the addition of two new sizes to its Glendyne range of natural slates, 60 by 30 and 50 by 30, 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, 60 by 30 and 50 by 30, can be pitched at a minimum of 25° and 20° in moderate exposure zones and 30° and 22.5° in severe exposure zones respectively. The slates exceed the common 2:1 length width ratio, allowing for specification on greater range of roof pitches. 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 distinctive blue-grey colour and, 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.
