Nôta, Roman, 1982- The impact of the spacer on the interior surface temperature in the detail of wood window glazing / Roman Nôta. -- Obr., tab. -- Lit. - The impact of the spacer of insulated glazing on the surface temperature in the glazing detail of a wooden windowis discussed in the paper. Six warm edge profiles from three manufacturers were assessed in the study, the model glazing with parameters 4-12-4-12-4 with the U-factor of 0.7 W/m2K. The detailed model of the spacer was compared also to the Two Box model. Subsequently, the Psi values of glazing (Ψg) for these spacers were determined and compared with the values from the Data sheet Psi values for windows (BUNDESVERBAND FLACHGLAS E.V.) and calculated values of Uw according to the STN EN ISO 10077. Following the calculation, minimum surface temperatures ranging from Δθsiof approx. 0.10°C for the detailedmodel to Δθsi of approx. 0.15 °C for the Two Box model was observed. When comparing the detailed models with the Two Box models, the minimum surface temperatures were in the range from approx. 0.5 °C representing 3.40 %. This difference was also observed incase of the exterior temperature resulting in condensation on the test window. In such case the difference between the detailed and Two Box model was at the value of 16.94%, while the Uw value for all studied variants was the same 1.7 W/m2K.
