Mitigating the Risk of Corrosion in Steelwork 

I-beams and RSJ's can be difficult to insulate; a common problem easily solved with Icynene where the steelwork is exposed. But what about the box sections where there is a risk of corrosion from condensation occurring on the *inside*

We were approached by the architect to provide a solution, highlighting an issue where there was a risk of corrosion from the humid air condensing inside the 140mm box sections of this fast food retail development. Initially the proposal was to inject the material via holes drilled at intervals to ensure the whole of the section was filled; however the steel arrived onsite and was immediately erected over two days...with only 2 x 30mm vent holes drilled to the face of the steel at either end. Rather than drilling extra holes (through 10mm steel, horizontally and at height..!) which would risk  delaying the project, the team at Kishorn Insulations used a modified (Pat. Pending) cannon nozzle and adjusted the reactor pressures to inject the material from the top of the columns. A visual check confirmed that the material was delivered to the base of the column, expelling any rainwater and then plugged to allow the Icynene to do the work - expanding up to 100 times it's volume to fill every corner and fill the column. After the columns were injected, the installers used an IR camera on the ground to track the progress of the rapidly expanding material as it heated the steel. The injection of LDC-50 to the box section verticals and braces ensures that the risk of corrosion is minimised...some of us will be enjoying our caramel lattes for longer than others!
