A warm roof (between rafter) is where it is above and between the rafters (so the rafters are kept warm). To create a warm pitched roof, insulation such as Kingspan Kooltherm K107/ Rocksilk® RS45 or Rockwool RWA45, should be fitted between and over the rafters. To go over your rafters use can also use our very Tekwarm PIR Rafter Board, this fit perfectly through your loft hatch and are extremely easy to handle. Our insulation solutions for warm roofs provide thermal efficiency, whilst also contributing to acoustic performance.
