Aluminium is durable and has a long service life. ZEKIN aluminium windows and doors are equipped with thermal insulation, which means that heat cannot penetrate in warm weather and cannot escape in cold weather conditions, and the energy efficiency of the self-built house will be maintained. In addition, one of the main advantages of aluminium windows is their minimalist appearance, which perfectly fits with modern projects and do not stand out in the foreground or distract from other architectural or decorative elements. Another advantage is that they can visually expand the space, making the interior brighter and more spacious. In addition to this, ZEKIN windows focus on durability and strength, and can resist any forced break-in attempts, so that homeowners can have peace of mind and feel safe.
