Improve Home Comfort and Natural Light With a New Patio Door

A patio door does more work than most homeowners think. It's often the largest glass opening in the house, which means an old, poorly sealed unit can undercut your comfort and your heating bill at the same time. 

Our energy-efficient patio doors are built with insulated vinyl frames and tight seals designed to withstand Maine's seasonal temperature swings by keeping warm air in during the winter and out during the summer. They also bring in more natural light patio doors are known for opening up kitchens, dens, and living rooms without sacrificing the thermal insulation your home depends on through a Windham winter.

• Sliding Patio Doors: A space-saving design that glides along a smooth sliding track system, ideal for rooms where a swinging door would eat up floor space.
