The insulation properties of a steel doorset can be as important for acoustic and strength purposes as they are for thermal transfer prevention. Samson Doors offer a wide range of insulated steel doorsets for almost any application with variable U values depending on requirements. If you are having an external doorset for a fire exit then why not also have it insulated? If you are specifying high security steel doors for your building then why not also have them insulated? Insulation is gradually forming a more important part of thermal transfer prevention with fire rated doors in the UK and although not a requirement yet, like it is in Europe, the reasoning behind it is obvious. When there is a raging fire on one side of a fire door then prevention of the intense heat to the non fire dies is surely desireable and common sense? The heat from a fire can make a door glow red and this will set fire to anything the other side after a short while, items like furniture and of course clothing on a person. Insulation is forming a bigger part of almost all steel doorset specification, regardless of the main function. Of course we do supply steel doorsets whose purpose is to only insulate a building or area inside a building too.
