Abstract This study used TRIZ methodology to develop a new steel stud for load bearing or non-load bearing walls. Technical contradiction of high strength with high insulation performance can be solved by TRIZ. We suppose a new shape of high-strength insulated (HSI) Stud. This study showed TRIZ can be usefully applied to the development of new construction materials by solving technical contradictions. Insulation performance of HSI stud can be improved approximately 12% compared to the standard KS stud. Although up to 3.9% of the flexural strength degradation is expected, compressive strength of HSI studs are improved from 4.1% to 8%. In conclusion, improved thermal performance and higher strength can be expected for the HSI stud developed using TRIZ.
