Energy renovation of your building reduces energy costs, increases living comfort and raises property value. Yilmaz Elektrotechnik offers window and front door replacement as well as modern sun protection systems in Leun and the Lahn-Dill district – including subsidy consultation and BAFA/KfW applications.
Old windows and leaky front doors are the biggest energy wasters in many buildings. By installing modern, energy-efficient triple-glazed windows and high-quality insulated front doors, you can reduce heating costs by up to 25%.
Sun protection systems such as electric roller shutters, external blinds and awnings regulate heat gain in summer and reduce cooling requirements. Combined with smart home control, they work fully automatically and contribute to energy savings year-round.
