ALU-SEAM® is the result of a 'no compromise' 5 year Research and Development programme. A true aluminium standing seam roof system, ALU-SEAM® has been fully engineered to offer unique advantages over other systems. Special attention has been paid to the principle of allowing for the thermal movement at all of the roof’s interfaces; areas that commonly produce premature failure or leakage if designed incorrectly. ALU-SEAM® is an aluminium system comprising of components specially engineered to accommodate roof pitches as low as 1.5°.
