Building

Heritage manor house in the village of Nadułki (parts from the 18th and 19th centuries). Owner and contractor: Sławomir Włoszczak, president of BOTI-CEL sp. z o.o. (the same contractor that implemented IzolPlus at Łazarski University in 2022).

Scope

IzolGlass Active TT film on window glazing. Window joinery replacement ruled out by conservation requirements - the film applied to the existing panes preserves the original window detail.

Measurements

At peak sunlight, the reference tile without film heated up by about 9.5°C more than the surface protected by the film. In summer, the internal temperature dropped by 5-6°C on the sunlit side; in winter, the temperature near the glazing became stable.
