Abstract [en]

In this report the structural material for a hotel module is qualitatively studied with focus onenvironment. The module is designed in composite sandwich material with cellular polymericfoam, Pet or PVC, covered by two glass fiber laminates on each side. This type of materialconstruction is traditionally used in transportation industry i.e. aerospace, aircraft, military shipsand yacht, demanding high stiffness in combination with low weight. But an increase in the usewithin the construction area can be seen especially within offshore industry were theenvironment is extremely corrosive.The investigated structure of a room and a bathroom includes floor, roof and three walls for eachmodule. A life cycle perspective, from cradle to grave (cradle) is used for the study starting withraw material production, product manufacturing, use of product and finally waste treatment indifferent forms. Parallel to the sandwich module building in conventional technique is includedfor comparison. This technique includes walls of wood joints with insulating material as mineralwool in between and then covered with gypsum wallboard. Joists are produced in concrete.As result environmental arguments are formed for the new sandwich alternatives and for theconventional technique. By just adding the arguments, for and against, turns out on favor for thePET sandwich module. For the material production the constituent materials for the sandwichgenerally presents higher CO2 emissions than the conventional building materials. But when itcomes to production and mounting of the module a number of arguments for the module can bestated. Better control of internal environment (working environment), efficient use of rawmaterial, effective transports. Compared to the conventional design the risk for problems withmoisture is non-existing for the sandwich structure.The best alternative for waste treatment of the sandwich module is reuse. Other alternative ismaterial recycling of glass fiber in combination with energy recovery for polyester and corematerial.For fire safety a recent full-scale test of a ship cabin point out the potential to design a fire safesandwich structure with appropriate insulating materials.
