The article concerns with the assessment of the thermal performance of a facade system using fastening elements made of glass fiber-reinforced plastic (GFRP). The article analyses the efficiency of the technical solution based on fibreglass plastic in comparison with its metal-based counterparts. We present theoretical calculation data and graphs of thermal fields, calculate heat losses through point and linear thermotechnical inhomogeneities. As opposed to a steel spacer assembly with a coefficient of thermal homogeneity up to 0.82, such a design coefficient for a fibreglass element (0.99) is close to 1.0. Herein, the GFRP fastening elements demonstrated practical efficiency when used in real modern facade building structures: the thermal insulation thickness for GFRP was 130 mm, while that for the steel elements was 160 mm when applied in the facade fixing system.
