Thermal Break Aluminum Doors in Córdoba: 2025 Guide

If you’re looking at aluminium doors with RPT in Córdoba, the first thing is to understand what you’re actually buying. RPT stands for “thermal break”: an insulating piece between the inside and outside faces of the aluminium. Translated into everyday life: less cold sneaking in during January and less heat rising off the floor in August. Here, with long summers and the sun beating down, you notice it when you have a door that doesn’t turn into a “radiator” by mid‑afternoon. Ever touched the frame and felt it burning hot? With RPT, that drops quite a bit. And in winter, if you use heating, you reduce that odd drafty feeling near the door, even when it’s properly closed.

A typical example: a flat in Ciudad Jardín with a living room opening onto a terrace. You swap the old “bare” aluminium door for one with RPT and, suddenly, the air conditioning doesn’t have to kick in nonstop. It’s not magic: it’s that the frame stops being a bridge that lets heat in. If your home gets direct sun, RPT isn’t a whim—it’s comfort.

Alright, you’re clear that you want RPT, but this is where a lot of people get tangled up: profiles, glazing, hardware… My friendly advice: focus on three things. First, the type of glass: if the door is large, double glazing with solar control helps a lot in Córdoba. Second, airtightness and watertightness (so no air or water gets in): ask about gaskets, a multipoint lock, and whether they do an on-site adjustment check. Third, the threshold: on doors that open out to a patio, a poorly resolved threshold ends up being that spot where dust and noise get in, and then you’re sticking on “patch” draught excluders.

Real-life situation: a neighbor replaces the door and complains they can still hear the street. It wasn’t the RPT; it was a loose lock and basic glazing. Or the other way around: good glass, but the sash rubs because the installation was rushed. That’s why you should ask directly: “Who measures and who installs? Is it the same crew? What happens if it starts rubbing after 15 days?” The best door in the world, if poorly installed, is just an average door.

In 2025, with energy prices where they are, the question isn’t “RPT yes or no?”, but “is it worth it in my case?”. If your door opens to the outside (terrace, patio, balcony) or you have a south/west exposure, it’s usually worth it because you reduce the thermal penalty right at the weakest point. If you live in an interior unit, with an enclosed communal corridor and no direct sun, the comfort jump may be smaller; in that case, sometimes it’s better to invest in a good sealing system, acoustic glass if noise bothers you, or even shutters and shading.

Think in concrete situations: do you have kids and the door gets opened a hundred times a day? Prioritize hardware and a latch that can take heavy use. Do you have a dog and go out to the patio? Look for a sturdy handle and a comfortable threshold so you don’t trip. Do you work from home near the door? Better glass and decent gaskets will get rid of that constant street hum. And watch the color: dark finishes in the sun heat up more; with RPT you handle it better, but if the sun hits hard, it’s the whole package (RPT + glazing) that makes the difference.
