The Panadero Prime comes from North Western Spain from historically, one of the oldest slate producing areas.
The slate offers a textured surface with moderately dressed edges. In addition, it has a blue-black appearance with a few small inert mineral inclusions giving this slate a distinctive charm.
The Panadero Prime is available in a 5mm thickness.
Prime Grade slates are of a high quality and good selection, they will require slightly more sorting and grading prior to fixing than the Ultra-Grade, but once done Prime-Grade slates offer a cost-effective solution that will still achieve a flat, uniform appearance on the roof.
Test results: The Panadero slate boasts a W-1, T-1, S-1 rating, meaning it conforms and surpasses all the top UK tests for water absorption, thermal cycle resistance and sulphur dioxide exposure.
