Patio Door Features:

  • Glide open with ease and take up little space

  • Our in-house installers ensure your Patio Door is professionally installed respecting our attention to detail and values


Our patio doors combine the best of design and functionality. Our new generation premium PVC patio doors bring a new level of  features and benefits to your home. Gone are the days of faulty sliders, substandard security and short lifespan of earlier patio doors.

A professionally installed patio door brings the outside in giving you a bright airy feel to any room. Choose from standard white and beige or a variety of outstanding custom colours.


Each patio door is available in 2, 3 and 4 panel configurations with a wide range of energy-efficient glazing options and decorative grilles. Standard 2-panel patio doors are available in 5′, 6′ and 8′ widths with two height options. Need a unique patio door configuration or size? Our patio doors are available in customs sizes to fit your home perfectly.


Our new generation patio doors aren’t just beautiful and functional, they are highly energy efficient. Patio doors of the past were widely known to provide inadequate seals. In fact they were so poor that home owners were forced to cover their doors with plastic to keep the London, Ontario weather out! Our patio doors are ENERGY STAR® qualified using multi-chamber frames and glazing.


Our patio doors are great but what really brings it all together is making sure your patio door is installed correctly. When shopping for patio doors asking a company if they have in-house installers is very important!  Our in-house installers not only ensure your patio door is CSA-A440 compliant but they’re fully trained to meet our high standards of installation requirements and values as well.


Buying a new patio door for your home is a significant purchase. Our expert sales staff will make sure you are educated on all of the options and help you choose the best one for your home.  Douglas Window & Door will help you make a smart choice, one that years from now, you’ll know with confidence that it was the right choice!
