Mini-guide to changing windows

Windows let light into the house, but they also play a fundamental role in the thermal and acoustic insulation of the interior. It may be time to change them, whether they are in poor condition or so old that they are not aesthetically pleasing. Read this mini-guide (with prices at the end) in which we explain the most important issues to consider.

Windows are composed of glass and profiles. There are several types of profiles: aluminum with thermal break and with a variety of finishes. Their advantage is that they are very resistant and durable. PVC, a very insulating material. And solid wood, although these usually have a dose of aluminum or PVC. The price depends on the type of opening, not only on the profiles.

When changing the windows you must take into account the combination of profile and glass, as this is the key to good insulation. And the glass occupies 80% of the window, so choosing the right one is essential. The most commonly used: low-emissivity double glazing (with up to three times more thermal insulation); acoustic (minimizing noise); intelligent (can control the passage of heat and light); or security.
