Milgard Trinsic Sliding Patio Doors Review

Milgard Trinsic Sliding Patio Doors Review

Milgard launched its newest line of windows and doors earlier this year – the Trinsic Series. The Trinsic Series is designed to satisfy the homeowner’s search for contemporary windows and doors.

In this post, we’ll review the Trinsic Sliding Vinyl Patio Doors

Watch the video below for a quick view of the Trinsic sliding patio door or keep reading to learn about the details of this door.


The frame components for this sliding patio door are made from high-performance vinyl. Some vendors simply buy vinyl material from third parties and then cut it to size to assemble a product. Milgard produces its own vinyl, giving it complete control over the style and quality of the material. Modern, high-quality vinyl is energy-efficient, low-maintenance, and can withstand Texas heat for years. 

Milgard offers other vinyl collections but the Trinsic Series was designed specifically for contemporary homes. These doors have a narrow frame profile, maximum glazing area, even sightlines, square corners, and clean mitered corners.
