Classic Polyurethane Window Sills and Trims

Classic window sills are essential architectural framing systems that emphasize a building's connection to its surroundings. Models such as P1460 and P1462 add significant depth to window perimeters, defining the 'facial features' of any facade with timeless elegance. Unlike traditional materials, Polure high-density polyurethane trims do not rot like wood, are not damaged by birds like expanded polystyrene (EPS), and do not absorb moisture like plaster. With a robust density of 180-200 kg/m³, these profiles maintain applied paint for many years without cracking or peeling. For the most balanced architectural aesthetic, we recommend selecting a trim width between 10% and 15% of the total window height. This ratio ensures you achieve the ideal golden proportion in your exterior design projects, blending durability with classical sophistication.
