HIDDEN FRAMES
DESIGN AND FUNCTIONAL ELEMENT

Hidden door frames and doors are a perfect and functional element of modern interiors professing the trend of minimalism and design purity. The door frames are hidden in the wall, the door is flush with the wall and one has the opportunity to enjoy the overall harmony and aesthetics of the interior.

The aesthetics of housing are not affected by individual elements separately, but by the overall harmony between them. Our concept of a door with a hidden doorframe does not require dominance in space, on the contrary - with its variability it can harmonize door spaces with the interior, set off disturbing elements and support the overall character of the apartment or house.

SURFACE FINISHES DOORS

Unique to the Fortius 52 concept is its variability. We always propose the optimal solution from the point of view of door construction and door frame profile - we solve not only dimensions and design, but also the surface itself, which can be provided with natural veneer, highlighted with RAL swatches or decorated in the same style as plaster.
Availability of doors in a range of RAL and NCS shades, natural veneers and HPL laminates. Preparing the wing for wallpaper, painting, screed or tiling.

PROTECTION HIDDEN DOOR FRAME DURING INSTALLATION

The Dorsis FORTIUS 52 concept is also "conceived" from the point of view of the installation itself - not only does the aluminum frame have a unique profile, facilitating assembly, but the construction is delivered assembled, including protective elements. The aim is to save time and costs during installation and to ensure that the door frames are not damaged or scratched during the final construction work.

HIDDEN FRAMES FORTIUS ACOUSTICS
ACOUSTIC DOORS IN A HIDDEN FRAME

Some rooms in a quiet area (such as bedrooms and children's rooms) require soundproofing from normal living areas. Likewise, in selected offices or meeting rooms, investors will appreciate the sound separation from the normal operation of an office building

Doors with a concealed Fortius Akustik doorframe can secure thanks to an automatic sill strip and a changed internal construction (hollow DTD filling or anti-noise plate) acoustic attenuation Rw 27 to 37dB, which means practical elimination of normal noise.

When an architect or designer designs an apartment for himself, we usually suspect that we can really look forward to the result. That thanks to the zero compromises that usually result from the dialogue between the designer and the investor, the result will be worth it!
