Economy Re-defined

ecolite patio

Attractive, maintenance-free ecoLite™ sliding glass patio doors are a great choice for homeowners looking for the best economy-class patio door available.

This welded frame patio door provides durability and strength all in one simple package. Our patented U-shape design offers superior flexibility, virtually eliminating seal failures, and our adjustable-wheel sliding system ensures smooth and quiet operation for years to come.

The low-E glass coating applied to one side of each ecoLite sliding door provides an energy-efficiency boost, as does the Intercept Blackline IG Spacer System. Standard on all ecoLite patio doors, the Blackline spacer features a one-piece, U-channel design that creates an effective thermal barrier to help reduce conducted heat loss.

The unique black coating also creates an aesthetically pleasing sight line at the edge of the patio door glass.

Other features include:

  • A strong, multi-chamber profile with interior and exterior accessory grooves
  • A bottom sill protector for optimal drainage
  • Various grid styles
  • An integrated nail fin for easy installation
