“The sound insulation is fabulous! There is a noticeable positive difference when you walk through to the new part of the school. The sound Insulation adds to a feeling of calm and there is no echo, even in such a lofty open space. This is particularly good for classrooms for young children as it adds to the comfort of the space and allows for calm and quiet as well as discussion and play. Thank you”Karen Crutchfield, Head Teacher, Braunton School
