ETERNIT THRUTONE SYNTHETIC LIGHTWEIGHT SLATES
Eternit Thrutone slate offers striking aesthetics with its smooth surface, square cut edges and Blue Black colour. This lightweight roof slate is available in six colours and three shapes providing even more design flexibility. With its low wastage and ease of installation Eternit Thrutone synthetic slates provide a cost-effective alternative to natural slates.
The slate was designed for the increasing demand for a more cost effective traditional slate aesthetic at lower pitches and were subjected to wind tunnel testing for driving rain and deluge conditions, equivalent to a once in 50 year extreme weather event. The weather tightness of roof tiles and slates decreases as the roof pitch gets lower as it takes longer for water to drain from the roof. The extreme testing of these slates was carried out, to ensure that the low pitch installation of the slates could sustain severe weather conditions.
The acrylic coating used on the slate surface provides good colour stability proven over long periods of exposure to UV and sunlight. The colour of the slates will lighten due to the exposure to sunlight and, which may affect the surface coating. This gradual lightening is similar to that experienced with natural slate.
