Detailed Product Information
Often rafters are not deep enough in their own right to accept the desired depth of insulation. STEICO Special Dry has been designed to be laid on top of the rafters, offering the desired insulation values with the least disruption to the inside. The boards are rigid, stable and most of all good insulators.
