GCA® shim has been designed to help prevent the over-compression of joints, particularly aluminium flashings, during construction.  Encased within the butyl profile is a beaded shim.  The butyl provides an effective weatherseal and the shim prevents the butyl being squashed flat or being forced out of the joint.  In a properly constructed and fixed joint, the butyl works within the componented system to allow for thermal expansion.
