Najważniejsze parametry okien do domu. Czy okna pasywne są najlepsze? 🪟

Choosing windows isn't just about deciding on the color of the frame or the shape of the handle! In today's episode, we take a closer look at the most important element of every window, the one through which we lose or gain the most heat: the glass. 🪟 Wondering what parameters have a real impact on your heating bills? In this video, I explain what they are and how three key indicators relate to each other: 👉 LT – how much visible light does your window let in? 👉 G – how much free thermal energy from the sun will heat your home? 👉 Ug – how much heat will escape through the glazing unit to the outside? To be clear, I'm conducting an energy simulation for a sample house (10x10 m). We use hard data to determine which is more cost-effective: "classic" windows (super warm, but letting in less sunlight) or "passive" windows (capturing free energy). We also debunk a popular myth about installing different glass panes on north and south facades! ✅ What did you pay attention to when choosing windows for your home?
