Windows systems are the weakest points of buildings in terms of thermal performance. Most part of the windows systems contain glass with high thermal transmittance constant. The aluminum material is mostly deployed as a frame which has a very high thermal conductivity. In this study, the thermal transmission coefficient optimization studies of an aluminum frame system is carried out, furthermore of the Çuhadaroğlu DS90 windows system to increase the thermal performance of the system. The gaps between the thermal barriers which used to prevent the thermal conduction of the aluminum material, are filled with four different insulation materials, and their effects on the Uf value are investigated. For the aluminum window section, calculations carried out employing the FLIXO program considering the ISO 10077 standard. The results show that the best performances are achieved with Aerogel and phenolytic foam. The best Uf value of 0.87 W/ (m2.K) was obtained by optimizing the parameters of the gasket, frame-sash, and thermal barrier material (by considering the cost parameter) of the windows system.
