Nová zelená úsporám: Co to je a jak to ovlivňuje vaše okna a dveře

When working with Nová zelená úsporám, státní program na podporu energetického vylepšování domů v České republice. Also known as NZÚ, it enables homeowners to receive financial support for replacing old windows and doors with energy-efficient ones. This isn’t just about saving on heating bills—it’s about making your home more comfortable, quieter, and better for the environment. If you’re thinking about replacing your windows or interior doors, this program could cut your costs by up to 40%.

Nová zelená úsporám isn’t just about windows. It also covers doors, insulation, ventilation systems, and even heat pumps. But for most households, the biggest impact comes from swapping out single-pane windows and drafty interior doors. Modern wooden windows and doors from Czech craftsmen—like the ones we specialize in—fit perfectly here. They’re not only energy-efficient but also durable, made from local wood, and designed to last decades. The program rewards quality, not just low prices, so choosing well-made products from Czech manufacturers gives you better chances of approval.

Many people assume they need to replace all windows at once to qualify, but that’s not true. You can apply for just one room, or even one window if it’s leaking heat. The key is proving the old ones are inefficient—usually through a simple energy assessment. You don’t need a full renovation. Just upgrading your windows and interior doors can be enough to get the grant. And since the program prioritizes projects that reduce energy consumption, products with low U-values (like our wooden windows with triple glazing) are favored.

It’s not just about the money. New windows and doors mean less condensation, fewer drafts, and better sound insulation. If you live near a busy street or have kids who need quiet for sleep, better doors and windows make a real difference. The program also encourages using local materials and labor, which supports Czech woodworking traditions and reduces the carbon footprint of your renovation.

What you’ll find below are real-life examples of how people used Nová zelená úsporám to upgrade their homes—whether they replaced windows in a 1970s panelák, upgraded interior doors in a family house, or combined both to maximize their grant. We’ll show you what documents you actually need, what common mistakes to avoid, and how to pick the right products that match both the program’s rules and your home’s style. No fluff. Just what works.
