Using natural sheep’s wool as insulation – a practice Emmerson Critchley Ltd upholds to this day – has been around for hundreds, if not thousands of years. Consider the incredible hanging tapestries depicting intricate hunting scenes: historically, these were fashioned with wool and hung within notable houses and palaces not only to provide opulent decoration but also as a means of retaining heat. Nowadays, sheep’s wool insulation – often made from British wool – comes in rolls or slabs and can be used in both walls and roofs.
