Passivhaus Aluminium Windows in Granada 2025

If you live in Granada, you’ve already noticed: in 2025 the conversation in many renovation projects has shifted from “which window should I install?” to “how do I stop my home from being an oven in summer and a fridge in January?”. And that’s where Passivhaus aluminium windows come in. It’s not just for show: it’s pure survival when you’ve got 40°C in July and cold nights in winter. The key is that a Passivhaus window isn’t “just” about good glass; it’s about true airtightness (so air doesn’t whistle through the seals), and about the frame not creating a thermal bridge that undermines your heating. A typical example: an apartment in Zaidín with old roller shutters and joinery that closes “more or less.” You switch to a window with a proper thermally broken profile, triple gasket and low-emissivity glazing, and suddenly you notice two very specific things: the living room no longer has that “draft” of cold near the sash, and the air conditioning holds up longer without kicking in every 10 minutes. In Granada, you feel the change in comfort and on the meter.

If they just tell you “it’s Passivhaus” and that’s it, be suspicious. What you really want is to know what you’re buying. To start, ask for numbers: the U-value of the whole unit (not just the glazing), air permeability, and whether the installation includes tape, a subframe, and continuous sealing. Because a top-tier window installed badly is like wearing a great coat with a broken zipper. With aluminium, the key is usually a wide, well-designed thermal break (not a half-hearted “thermal break”), plus the right glazing: in Granada, double glazing with solar control often works very well if you have a south/west orientation and lots of sun, and triple glazing if you want to push winter comfort and quiet to the limit. And watch out for the shutter: if you keep an old, uninsulated shutter box, you’re letting cold/heat in all by yourself. Real case: on Camino de Ronda, full renovation, impeccable new windows… and they still felt a draft. The culprit? The shutter box with no insulation or airtightness. They fixed it and it completely changed the story.

The best thing about well-made Passivhaus windows is that you don’t notice them because of “how nice they look,” but because of very everyday things. You wake up and the bedroom isn’t freezing, you sit by the window and you don’t get that cold-wall feeling, and the street noise drops off all at once. In Granada this is especially noticeable if you live near busy roads or lively areas: a good combination of glazing (acoustic laminated glass if needed) and airtight frames reduces that constant “background” noise. Plus, by controlling air leaks, the home becomes more stable: the thermostat doesn’t swing wildly. That said, there’s one point almost nobody tells you: if you greatly improve airtightness, it’s worth thinking about ventilation (even a simple solution) so you’re not living with the window open “out of habit.” And another practical thing: before spending money, check orientation and shading. A top-floor flat in La Chana with afternoon sun is not the same as an interior apartment. The right Passivhaus window isn’t the most expensive one: it’s the one that fits your home and how you use it.
