Having just moved to Spain not long ago, I’ve been house-hunting and helping friends with renovations. I’ve noticed a really interesting detail: the windows here, especially in villas, are quite different from what I was used to in China. There seems to be a lot to them, so I thought I’d share my observations. Feel free to add your own!
The Indispensable Feature: Persiana Roller Shutters
When I first arrived, I was really curious why almost every house has a roll-down shutter on the outside of its windows. I later learned this is called a Persiana, and it’s practically standard issue for Spanish windows. Its function goes far beyond simply blocking light. In the summer, especially here in Andalusia, the sun can be brutally strong. Lowering the Persiana instantly cools the room by several degrees—often more effective than an air conditioner—and provides a complete blackout. Siesta lovers, rejoice! In winter, it also helps to block wind and retain heat. Plus, a crucial point for practical window decoration is security! Most Persianas are very sturdy and nearly impossible to open from the outside when closed, giving you a great sense of security.

Choosing Materials and Styles
After visiting numerous building material markets and neighbors’ homes, I’ve found that there’s a wide variety of materials and styles for the windows themselves. The most common are PVC and aluminum alloy. PVC generally offers better thermal and sound insulation and comes in many colors, including white and faux wood grain. Aluminum alloy is more robust and durable, especially the kind with a ‘thermal break’, which also has excellent insulation properties. As for style, besides the sliding windows we often see, a more common type here is the tilt-and-turn window. This window can open inwards like a regular door or tilt inwards from the top, leaving a small gap. This allows for ventilation without worrying about rain getting in or someone climbing through from the outside, making it extremely practical.
Comparison of Common Window Types
| Type | Pros | Cons |
| Sliding Window | Saves space, easy to operate | Relatively poor sealing and sound insulation |
| Tilt-and-Turn Window | Good sealing, secure, flexible ventilation | Slightly higher price, opens inward taking up interior space |
| Awning Window | Good rain protection, suitable for kitchens and bathrooms | Difficult to clean the exterior glass |
Choosing the Glass: More Than Just for the View
Finally, let’s talk about the glass. New or renovated houses in Spain now typically come standard with double-glazed insulating glass, also known by the brand name Climalit. It consists of two panes of glass separated by a space that can be filled with an inert gas, providing top-notch thermal and sound insulation. For anyone living by a busy road, upgrading to these windows can make the world feel peaceful. Some people go even further, choosing glass with solar control coatings or laminated safety glass, maxing out the functionality. In short, a good window can truly enhance your quality of life, and it’s money well spent
