Durable, Canadian-Made Double Hung Windows for Homeowners in Southwestern Ontario

Sentry Windows & Doors is a family-owned and -operated company providing homeowners throughout Southwestern Ontario with top-quality vinyl replacement windows. As locals, we understand just how important it is to outfit your home with durable, high-performing windows that will stand up to anything Mother Nature can throw at them and keep your family safe and warm during frigid Canadian winters. Our proprietary double hung windows are highly sought after for their exceptional quality and the many benefits they offer.

What Are Double Hung Windows?

These days, double hung windows are the most popular style of windows on homes in North America. Featuring two operable sashes, double hung windows are incredibly versatile and convenient. Opening both sashes allows hot air to escape through the top while cool air enters through the bottom, thus creating a cross breeze effect with a single window. Furthermore, because both sashes can tilt inward, cleaning these windows is quick and easy and can be done from inside your home.

Benefits of Sentry Windows

Sentry Windows are proprietary products, manufactured in Canada with 100 percent virgin PVC.  Our double hung windows boast a number of features you’re sure to love. For example, they are:

  • Equipped with insulated frames and Low-E glass for superior energy efficiency
  • Fusion-welded, making their frames extremely rigid and durable
  • Made from 100 percent non-recycled PVC, which means they won’t chalk or fade
  • Covered by an impressive, no-nonsense lifetime warranty
