Colour Options
The Mini-Stonewold tile is available in three attractive tones, offering style choice without compromising durability:

With a coated surface finish, this concrete tile provides enhanced colour stability and protection against weathering. Its precise interlock and strong concrete composition ensure long-lasting performance, while excellent dimensional accuracy contributes to a clean, consistent roof finish.
Each tile measures 418mm x 334mm, with a hanging length of 398mm, ensuring flexible installation options. The system accommodates headlaps between 75mm and 125mm, allowing installers to adapt to pitch requirements from 17.5° up to vertical (90°). When laid at maximum gauge, coverage is highly efficient at 9.9 tiles per m², and the roof build-up remains durable and structurally robust.
