If you live in Alicante and are planning to upgrade your aluminium windows, 2024–2025 brings major innovations. New EU energy-efficiency guidelines are driving lower Uw values, translating into greater comfort and lower heating and cooling costs. Expect next‑gen thermal-break profiles, co‑extruded gaskets and insulating foams, plus ultra‑slim frames and concealed sashes that maximise natural light. In glazing, triple panes with low‑e coatings and solar control tailored to the Mediterranean climate help keep homes cool in summer. Sustainability leads: low‑carbon aluminium with high recycled content, solvent‑free powder coatings, and matte anodised finishes in earth tones and blacks. Smart windows are taking off too—whisper‑quiet motorisation, automatic micro‑ventilation, CO2 and rain sensors, and control via app or voice assistants. Clear benefits include superior thermal and acoustic insulation, enhanced security, minimal maintenance, and added property value. Target specifications: Uw ≤ 1.2 W/m²K, Rw ≥ 40 dB, and Class 4 air permeability for top performance in Alicante.
