Double Hung Windows


Made from a beautifully hand crafted design and colonial framing, EcoTech’s double hung windows provide added efficiency to your home. Double hung windows and single hung windows commonly get confused for one another. The main difference between these two types of windows is that double hung windows have a full screen and two operable sashes allowing the window to move up and down easily. Energy Star sealed and certified, these windows will protect against heat loss, even on the coldest day of the year!

Made from high quality, tough, durable vinyl and available in a range of designer colors, EcoTech’s double hung windows will last and perform for years to come. With dual interlocking rails, an overlapping screen frame, and a heavy duty cam lock, this window will enhance any part of the home. With its reputation for being an excellent replacement window, double hung windows offer functionality, elegance and practicality. No drafts and reduced energy costs also make this window a great choice for you and your family.

Energy-Efficient Windows & Doors

All of our windows and doors have the Energy Star seal and provide maximum home insulation. Our vinyl windows are more energy-efficient, fire-resistant and modern than wooden or aluminum windows. Canadian-made windows and doors from EcoTech feature advanced structural designs, high quality sealing systems and stunning good looks.

EcoTech Windows & Doors also offers insulated spacers within the sealed glass between window panes to help protect against condensation. We apply low emissive coatings to all our window surfaces to protect against heat loss. At EcoTech, we make sure your home is warm, dry, energy-efficient and beautiful for years to come.
