The Penrhyn Heather Blue County Slate 400 x 375mm is a natural Welsh roofing slate chosen for its wider format. Typically used at verges, hips, and similar roof details, it provides extra coverage where required and is commonly installed with 400 x 250mm slates for a precise finish.
Ideal for both traditional and contemporary pitched roofs, this slate helps achieve neat, robust edges and complex junctions. Its natural composition and colour remain stable over time, making it suitable for new constructions and refurbishment projects where both performance and appearance are key considerations.
