Meir Roofing

Is a well established and proven insulation material formed from pure granulated cork, compressed, steam baked and held together by the natural cork gum.  It is widely used as a heat resistant and stable facing to rigid urethane insulation to form a composite insulation, is resistant to moisture and decay and is suitable for use above high humidity conditions.

It provides a substrate of good laminar and compressive strength suitable for asphalt roofing and with its low coefficient of thermal expansion will accept a full bonded built-up roofing specification. Although cork is somewhat friable during handling it is firm under foot traffic and is a suitable insulation to use below membranes which are subject to continual foot traffic, but an underlay may be required to provide support over the troughs of metal decking.   For general handling strength, a minimum 25mm thickness is recommended.
