If you're looking for the most energy efficient windows on the market, with a modern and sleek design a casement window might be the perfect solution for you.  Casement windows are versatile windows that are most commonly installed in kitchens, bathrooms and bedrooms for ventilation and in basements as egress windows.  They have a variety of choices like single casement, double casement, triple casement and specialty casement.  Casement windows consist of a single sash of glass which creates a more air-resistant barrier than other more complex window types. This type of air seal increases the thermal of the window to significantly help you keep the heat and cold out, which is especially important for the Chicagoland winters and hot summers.
