Why Choose Treated Redwood Shiplap?
Redwood is known for its excellent stability, attractive grain, and durability. Combined with professional pressure treatment, this shiplap ensures great long-term performance even in the UK climate. The overlapping profile forms a tight, secure joint that efficiently sheds rainwater, helping to protect the structure underneath.
With its smooth finish and reliable treatment, this cladding offers both a premium appearance and practical weather protection, making it an excellent choice for all outdoor buildings.
