Homeowners advised on energy‑saving measures for summer heat and winter cold

Experts recommend simple, low‑cost steps to keep attics cooler in summer. Sealing gaps around windows, skylights, and attic doors can cut heat gain by 10‑20 %. Applying solar‑control films to glass reduces solar heat by up to 70 %, especially on west‑facing roofs. Improving ventilation when outside air is cooler also helps lower indoor temperatures.

For winter, similar sealing techniques are advised. Installing adhesive weather‑stripping, silicone tape or sealant around windows and external doors can prevent 20‑30 % of heat loss. Purging radiators to remove trapped air and positioning thermostats in the most used rooms improve heating efficiency. Professional checks cost under €50, while DIY fixes require only basic tools and inexpensive materials.
