Modern design: flush-mounted primed doors are the perfect choice for stylish interiors. Thanks to the minimalist design and the absence of protruding parts, they visually expand the space of a house or apartment. Shaker 1 Panel Primed door fits harmoniously into any room or becomes an accent element of the living space.

Door construction: stile and rail doors symbolize the best traditions of American craftsmanship. We use linear pieces of lumber assembled into a single structure to ensure the functionality and durability of the slab.

Door filling: MDF panels. This material provides reliable soundproofing and keeps the heat inside the room. Furthermore, the door has good sound insulation, especially with the automatic threshold.

High-quality finish: primer. You can paint the primed door in any shade, wallpaper or decorate it with plaster.

Warranty: 2 years.
