ENERGY STAR Rated Casement Windows

Window Mart’s casement windows feature an excellent ENERGY STAR rating. They are made from 100% lead-free uPVC compound and boast a unique multi-chamber construction that boosts thermal performance.

What is a Casement Window?

Casement Windows are an attractive addition to any home, providing unparalleled ventilation and ease of operation. Commonly used in bathrooms or kitchens because of their ability to increase airflow, casement windows are hinged along one side. The main difference between casement and awning windows is the direction which they open, as awning windows are hinged along the top of the sash. With the simple turn of a handle, the supporting arm opens and closes casement windows to either the left or right. Casement windows conveniently open to 90 degrees, allowing for easy cleaning from inside or outside your home.  These windows also feature an excellent seal, which makes them one of the most energy efficient options on the market.

Window Mart casement windows are available in a wide array of colors, sizes, and configurations. We custom build every casement window to fit your home, complete with special features like window grills or custom hardware. At Window Mart we guarantee 100% customer satisfaction with our top-rated products and window installation services.

    What Our Clients Say

    Gor was our Window Mart representative who came to do our quote today and we could not be happier with the service he provided!! He was prepared, knowledgeable, personable, polite, considerate, honest, and genuinely wanted to see us get the best deal we could! I would recommend Gor from Window Mart all day, everyday! So very impressed with the experience overall!
    After compared with other companies,we ultimately chose Window Mart. As their staff member Andrei was highly professional. He provided us with detailed explanations and recommendations based on our home conditions, which made us trust them a lot. We are looking forward to seeing our new windows in 12 weeks.
    Mikhail Mezentsev great guy.So honest worked hard to make sure we understand and see what we will be getting.We were 100% happy.
    We recently invited Mikhail Mezensev to discuss the window replacement at our home.Mikhail took his time to understand our needs and recommended the product most suitable.
    Daniil the sales consultant was very professional.
    This is the third window renovation that we have done using Window Mart as the contractor. In total 11 windows. We could not be more pleased with both the quality of the product and the appearance of the windows. Of course, cost is always a concern. New windows in an older home do not come cheap. I suppose that we could have gone with a produce of lesser quality but that just doesn't make any sense. We were still satisified with the cost of the product that we got from Window Mart. But the really wonderful thing about this company is the installers! We have had three different pairs of guys for our three reno projects. In all three cases they were friendly, really knowledgable, and highly skilled. Our last project completed in April of 2023 was 6 basement windows. This was not easy work. When they were done the windows casings blended in with the existing exterior and interior perfectly. They covered all out floors with tarps so as not to track is dirt, etc. And they do a wonderful job of cleaning up after the job is finished. Great follow up by the company as well. We'll give Window Mart an overall grade 13 out of 10!
