Modern frame

The A250 has the clean, narrow sight lines that you’d expect with a modern aluminum frame. These thin frames accentuate the views to the outside and bring the outside in with style.

Durability

Due to its rigidity and sturdiness, the A250 Thermally Improved Aluminum door is highly resistant to outside weather elements. This durability leads to an extremely long lifespan for the door.

Strength

Built with high-quality components, the A250 is a sturdy door. Its extraordinary strength allows it to hold large expanses of glass, making the A250 an ideal choice for homeowners who want to merge the interior with the exterior.

Energy Efficient

Equipped with a thermal barrier, the A250 is an exceptionally energy-efficient door. The thermal barrier is made possible by the polyurethane that’s placed between the frame, reducing the flow of heat and improving the door’s insulating ability.
