After fitting, Lochinvar’s decorating team adds three more finishing coats, ensuring both aesthetics and security exceed British standards.Our timber frames are not just beautiful—they’re built to last. They uphold stringent performance metrics, including outstanding thermal efficiency, weather resistance, and acoustic performance.
