Milgard Trinsic Series Patio Doors

The Milgard Trinsic Series is a contemporary vinyl patio door with a frame profile so narrow, you’ll hardly know it’s there. The Trinsic Series features the slimmest frame profile in the Milgard patio door lineup — minimal sight lines let the glass take center stage. The clean, square-edged profile pairs equally well with modern architecture and large-panel glass remodels.

milgard trinsic series Durability

Durability and Low Maintenance

Milgard produces their own vinyl formula for the Trinsic Series patio door. The durable frames will not absorb moisture and do not require painting or refinishing. Available with double or triple-pane glass options to meet ENERGY STAR® requirements for your climate zone.

Hardware

Trinsic Series sliding patio doors come with a newly designed, squared off handle. This crisp, clean, contemporary look offers a very modern flair. Consider the optional upgrade for an even narrower handle that blends seamlessly into the frame.

Unique Vinyl Formula

Milgard extrudes and fabricates their own frame materials in-house, controlling quality from formula to finished product. The result is a patio door frame that won't absorb moisture, won't need painting.
