DescriptionManufacturer of sandwich panels for roofing, part of the Ángel López group, with a plant in Los Corrales de Buelna (Cantabria). Within its range of timber panels, it offers a line with a cork core as an alternative to the usual extruded polystyrene: cork provides greater thermal inertia, good acoustic performance and a renewable origin. The sandwich panel combines interior finish, insulation and roof support in a single piece. Environmental documentation pending verification.
