The quality, features and ease of installation are worth the purchase. The online information about all their lines are clear, with valuable information one requires to make a judgement. With Milgard's record of quality, through the years that we used their products, we are very happy. - Salt Spring Island, BC, Canada

Combinations and Mulling

All Milgard windows and doors are built to your specifications. So while we're showing a few sample combinations, there are literally hundreds of products to combine and ways to combine them. A Milgard Certified Dealer can help you explore the possibilities.


Energy Calculator

The Milgard Energy Calculator provides a quick and easy way to help you select windows and doors that can meet local energy codes and project requirements. This tool gives you the flexibility to select the required ENERGY STAR® zone, u-factor, SHGC or VT, and determine which Milgard window and door products meet the selected requirements. Additional selections can also be made based on product series, operating style, glass type, grids and spacer type.

8 Premium Exterior Vinyl Finishes

Now you have more flexibility to color coordinate with eight premium exterior vinyl finishes in addition to traditional white and tan. From the newly popular 'Fog' to rich, bold 'Espresso', get inspired with all the possibilities. To create color that lasts, Milgard developed a new coating technology that allows UV rays to pass through the paint and reflect off the vinyl frame. This preserves the exterior color and finish.
