Trinity Black Prefinished Bevelled Glazed Internal Door

Balancing natural light with considered design can be challenging in modern interiors. The Deanta Trinity Black Prefinished Bevelled Glazed Door FSC offers a refined solution, combining structured panel detailing with bevelled glazing to introduce brightness without sacrificing privacy.

The distinctive triple square vertical panel layout creates subtle architectural definition, while the clear one-sided bevelled glass allows light to travel between rooms. This makes the door particularly well-suited to hallways, living areas, and home offices where openness is desired without fully exposing the space.

If you're looking for this style of door in a non-fire-rated variant, we stock the Trinity Black Door, perfect for achieving the same look at a lower price. or the fire-Trinity FD30 Fire Door, which is perfect for those looking to keep their home safe. Or if you are looking for a brighter variant, we also have the Trinity White Primed Door, for those looking for a brighter version of this door!

Finished in a deep prefinished black, the Trinity delivers immediate visual impact with no additional decorating required. The dark tone contrasts cleanly against lighter walls and modern interiors, creating depth and cohesion while maintaining a timeless aesthetic.

This door comes with a 10-year warranty and pairs up perfectly with our compatible hinges, latches, handles, and other accessories, which all in all help create that premium, final, and finished look. We strongly recommend considering them!

Crafted from FSC® certified timber, this internal door supports responsible sourcing practices without compromising durability or construction quality. With a generous trimming allowance and a 10-year manufacturer’s warranty from Deanta, it offers both flexibility and long-term reassurance.

As this door is prefinished, it is ready for installation, but will require refinishing in the areas you have cut or modified to fit furniture on your door. For what treatment to use on this internal door, we would recommend a triple coat of Treatex clear satin finish on those modified spots.
