Is this door energy efficient?

Yes. It is Energy Star approved and uses triple-glazed, insulated glass in a 1-3/4 inch fiberglass slab, which helps with heat loss and condensation compared with single-pane doors.

What sizes are available?

The unit comes in three widths: 33.625, 35.625 and 37.625 inches, all 82 inches tall. Measure your rough opening before ordering, since framing and trim add to the slab size.

Does the glass come tempered?

Yes. The Ari 3-lite glass is tempered and safety-rated, and the 1-inch triple glazing is insulated. That matters for doors near walkways or within reach of children.

Is the door prehung or slab only?

The listing describes the door system as swing with a 1-3/4 inch slab. Confirm with the seller whether a frame, threshold and hardware are included before you buy.

Can I paint a smooth fiberglass door?

Yes. The smooth skin is designed to take exterior paint, so you can match your home's color. Follow the manufacturer's prep and paint instructions to keep the warranty valid.

When is the best time to buy?

Entry doors often see discounts in spring and fall remodeling promotions. With only one store listing it new, watch for seasonal sales rather than expecting frequent price drops.
