Technical reference for builders, architects and property owners
North Window Daily covers the technical aspects of passive and energy-efficient window systems as they apply to residential construction in Poland. Content focuses on verifiable standards, measurement methods and installation details rather than product promotion.
Polish construction is governed by Warunki Techniczne (WT), a set of technical conditions updated periodically by the Ministry of Development and Technology. The 2021 revision introduced significantly tighter requirements for window U-values and whole-building energy performance, bringing Polish standards closer to the Passivhaus benchmark used across central Europe.
