Its crisp white finish and simple linear design make it a stylish option for hallways, kitchens, dining rooms, living spaces and home offices.
The frosted glazed panels are designed to brighten interior spaces without leaving rooms feeling fully exposed.

Manufactured using a Solid Engineered Core, the Sierra Blanco 3L provides strength, stability and durability. The solid engineered construction gives the door a reassuringly substantial feel in operation compared with lightweight hollow core alternatives.
The smooth white face material is an important feature of this design. It is not a textured or grained finish, making it ideal for customers looking for a clean, modern white internal door with a crisp contemporary appearance.
The Sierra Blanco 3L is available in three popular internal door sizes, with approximate weights ranging from 30kg to 35kg depending on the selected size. This gives the door a quality feel while remaining practical for internal use.
