Castelia™ offers the latest in aluminum cladding technology: No more direct attachment of aluminum cladding directly
onto the wood frame. Instead we use special durable brackets to fix the aluminum onto the wooden jambs. In this way,
heat caused by solar radiation will allow aluminum to contract independently from the wood. The benefit is no more
cracked aluminum cladding caused by excessive heat build-up. Plus, integrated ventilation channels allow moisture to
escape freely rather than being trapped between the wood and the aluminum which otherwise would cause the wood
to rot.
