At YKK AP we design and build every component of our IWIN S series windows. From extruded aluminium to handles and locks. An important feature for projects is that YKK AP IWIN-S windows or doors increase the proportion of glazing in the window. This means more light, a more pleasant living environment and a facade imbued with a timeless elegance.The new window systems are available not only in different surface finishes and colours but also with a varying levels of air-tightness and water-tightness. We can also create customised solutions for any project. Our in-house facility from extrusion to fittings and hardware allow for creating individual design solutions.
