Slate wall cladding (10mm, 20mm, 30mm)
Natural metamorphic stone cladding offering exceptional durability, low water absorption (<0.4%), and non-combustible fire rating. Available in 10mm, 20mm, and 30mm thicknesses for interior and exterior wall applications across all Australian climate zones.
Natural metamorphic stone cladding offering exceptional durability, low water absorption (<0.4%), and non-combustible fire rating. Available in 10mm, 20mm, and 30mm thicknesses for interior and exterior wall applications across all Australian climate zones.
Slate wall cladding is a fine-grained, foliated metamorphic rock derived from shale through low-grade regional metamorphism. Characterised by its distinctive slaty cleavage allowing splitting into thin sheets, slate provides superior weatherproofing with water absorption below 0.4% (AS 4456.11). The material offers 100+ year service life with minimal maintenance, natural fire resistance (AS 1530.1 non-combustible), and excellent resistance to UV exposure, salt spray, and freeze-thaw cycles. Available in natural grey, green, purple, and black tones.
