We understand the importance of quality and sustainability regarding our oak. That's why we exclusively employ well-air-dried oak, ensuring durability, aesthetic appeal, and structural integrity that stands the test of time. Unlike freshly sawn oak - which is more for outdoor furniture - containing high moisture contents leading to large-scale warping, our carefully selected air-dried oak offers long-term stability, a smoother finish, and a better appearance.

We are dedicated to playing our part in a greener and more sustainable future, and we're proud to source our oak from forests that are FSC (Forest Stewardship Council) and PEFC (Programme for the Endorsement of Forest Certification) certified. This guarantees our oak's impeccable quality and ensures that it is ethically sourced with a focus on conserving the environment.

When you choose us, you're choosing quality and a better world. Let our oak's natural beauty, resilience, and sustainability be the foundation of your fireplace.
