In winter, when humidity drops and the dry westerly wind blows, wood contracts. The door closes well but there's a visible gap between the door and frame, allowing air and noise to pass through. This is the natural cycle of wood and can only be avoided in two ways. Either replace it with an MDF or multi-layered door that doesn't have this movement, or learn to live with it and adjust the hinges periodically. A complete aerothermal installation is a serious project. It begins with calculating the property's thermal loads, sizing the equipment according to real needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and outdoor unit, and a fixed quote.

A much-requested improvement today is combining a motorised roller blind with a retractable insect screen integrated into the same box. This allows both the blind and the insect screen to be operated independently, both hidden when not in use. It's the standard solution in modern new builds. For existing home renovations, it requires replacing the entire box with a new, deeper one that houses both systems. Motorisation requires electrical power to the top box. If the box wall already has an electrical cable nearby (typically from the adjacent room's socket), installation is straightforward. If not, a cable must be run through an external conduit or a hidden channel. The complete motorisation operation takes 2-3 hours per roller blind when power is nearby. For all the roller blinds in an entire house, we can do it in 1-2 days. Changing the tape itself is a 30-45 minute operation per roller blind when the box is accessible. The real complexity lies in locating the internal break, opening the box without damaging it, removing the axle, taking out the old tape, passing the new one through the slats and the winder. Then reassembling the entire unit without misaligning the slats. For someone who has never done it, a roller blind can take three hours and end up worse than before. For technicians who do it daily, it's a 30-minute job with a clean result.

If the blind's slats are cracked, discoloured, and brittle (typical for blinds over 25-30 years old exposed to direct sun), repairing point by point stops being economically viable. Replacing the entire blind with a modern model costs two to three times more than just changing the tape. In return, it gives you another 25-30 years of trouble-free use. Modern slats are injected and filled with polyurethane, much more insulating than old hollow ones, thus improving thermal insulation. And you can request integrated motorisation from the factory. For more modern windows with a tilt-and-turn profile and thermal break, the fittings are of better quality but also require maintenance. Lubricating the hinges and adjusting the closing points every 2-3 years significantly extends their lifespan and prevents air from entering in winter or them becoming too hard to open.

The price of insulation in Navas typically ranges between 208 and 2970 euros. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. If it becomes misaligned again within 30 days due to the same cause, we return at no extra cost.
