Technology

Leaf construction and fitting method, common to all models in the catalogue.

Leaf construction

We make door linings and architraves from solid timber. For production we use oak, meranti, pine and larch. The doors are protected against moisture, so they can go in any room, including bathrooms and kitchens. Timber also provides good sound insulation.

Panelled doors

Rebated, flush-fitting and sliding

We make both constructions in each of the three variants. The choice changes how the closed door looks and how it works day to day.

Rebated

The leaf sits slightly proud of the door lining. The rebate, also called a lip, overlaps the lining and hides the lock and the gap. The hinges remain visible.

  • Simple construction
  • Easy installation and hinge adjustment
  • Good acoustic properties
  • High durability

Flush-fitting

The leaf sits directly in the door lining, and the edge of the closed door is flush with it. The hinges stay concealed; models with visible hinges are also available.

  • Less risk of trapped fingers
  • A wider clear opening
  • Wheelchair access
  • Easier to keep clean

Sliding

We also make every model in the catalogue as a sliding door.

  • Suits rooms with an unusual layout
  • A solid leaf that does not need wedging when there is a draught
  • Less risk of slamming
  • A lock or bolt can be fitted if needed

When choosing flush-fitting doors: production requires different technology, so the price is higher than for rebated doors. The hinges need precise adjustment, and changing the door type in an existing opening means replacing the door lining.

Rebated doors – which interiors they suit

Rebated doors are still the most popular type of door, common in housing and beyond. The rebate conceals the lock and the gap at the door lining, so the whole construction looks visually lighter. They are also valued for their versatile, timeless character.

Because of their classic look, rebated doors are intended above all for traditionally furnished interiors, such as Provençal, romantic or retro style. Today, however, thanks to the wide choice of models, rebated doors also suit modern interiors.

We particularly recommend rebated doors for small rooms that are rarely closed. Thanks to the concealed lock, the open door leaf always looks neat.

What to look for when choosing rebated doors

The most important parameter to know before buying a door is its size. To choose a model with the right dimensions, the width and height of the wall opening must be measured accurately. Next, it is worth thinking about the design and colour of the door so that it matches the interior. Rebated doors look excellent combined with glazing bars and decorative details.

Flush-fitting doors – advantages

Flush-fitting (non-rebated) doors are regarded as a modern construction. Because the whole leaf sits within the lining, it forms a single composition with it and also hides the hinges. This also makes flush-fitting doors look more substantial than traditionally built doors, so they can be used in many interiors. Although they are not the most common type of door, they are winning more and more fans, thanks to their versatile design and the use of a magnetic lock.

Flush-fitting doors are widely considered the best choice when there are small children or pets at home. In this type of construction, the way the leaf closes minimises the risk of trapped fingers. Another advantage of the single-plane layout is that the free floor area around the door looks larger. Flush-fitting doors allow a larger door opening, so the room feels more spacious and more light reaches it. Contrary to popular belief, non-rebated doors are just as durable as other types of door.

Flush-fitting doors are also easier to keep clean: with no rebate, there is nowhere for dirt to collect. If the leaf ever needs replacing, the cost of the repair is considerably lower than with rebated doors.

They are also an excellent solution for people with disabilities. The frameless construction makes it easier for wheelchair users to pass through and lets them move freely around the home.

Where flush-fitting doors are most often fitted

Flush-fitting internal doors are usually used in narrow rooms, because they look as if they were built into the wall. They also work well in tight hallways. Flush-fitting doors are chosen above all by people who want to furnish their home or office in a modern, industrial or minimalist style. That does not mean, however, that flush-fitting doors look out of place in other interiors.

Door types we offer

Our range includes internal doors that are rebated, flush-fitting, reverse-opening, folding, pivot or glass, as well as doors with a concealed frame. Sliding doors are a separate group, described above together with the leaf construction.

We make all of them to measure only - we have no standard sizes for mass production. The catalogue on the website serves as inspiration and a starting point for discussion, and we tailor every door to the client’s needs, the architect’s vision and the style of the interior.

Oiled and patinated finish

As standard, we paint doors with water-based lacquers. The range is complemented by oiled and patinated doors, which are finished differently from painted ones.

Oiling means saturating the surface with natural oils. The oil is rubbed in by hand, so the structure of the wood remains visible, while the surface is hardened and protected against moisture and sunlight.

  • accentuated grain and figure
  • richer colour
  • satin sheen

Patination gives the doors a visually aged look. They take on a retro appearance with accentuated grain, which makes them a good match for interiors in a retro, rustic or Scandinavian style.

Glazed panels and stained glass

Glazed panels bring light into rooms and allow areas within the building to be subtly separated. We make the panes in various shapes, sizes and colours, in frosted, sandblasted, patterned or stained glass.

With patterned glass and stained glass, the decorative elements are enclosed within the sealed unit, so they are easy to maintain. We also make stained glass to an individual design.

How to choose glazed internal doors for an interior

Internal doors are an important part of an interior, so their style should match the furnishings of the room. Internal doors kept in one consistent line that echoes the surrounding design create an orderly living space.

We make glazed timber internal doors to order, in the chosen style, and advise on matching them to the look of the interior.

Patterned glass designs

  • Szynszyla, in white and brown
  • Deszczyk, in white and brown
  • Silvit, in white and brown
  • Alt Deutsch, in clear and brown
  • Kocie łapy
  • Picasso
  • Delta polska and Delta biała mat
  • Crepi
  • Flutes
  • Master Ligne, Master Point, Master Ray, Master Shaine
  • Niagara
  • Waterdrop

Samples of the designs are available to view when choosing a model.

Magnetic latch

The aesthetic benefits of this solution are most visible in flush-fitting doors. The latch works by the attraction of opposite poles of magnets placed in the leaf and in the strike plate. We use LOB latches, certified for their service life.

  • The latch bolt retracts when the door is open
  • Strike plate not visible from the face of the door lining
  • Catches as the leaf closes against the seal, with no metallic sound

The samples show roughly how the colour looks on a given timber species. The final appearance of the joinery depends on the type of timber, its colour and grain, and the type of paint coating.

Coating types

The final appearance of the joinery depends on the timber species, its colour and grain, and the type of paint coating.

  • Translucent stain: the timber grain remains visible
  • Opaque: the grain is not visible
  • Oiled: translucent, penetrates deeply

RAL colour chart

Beyond the colours and stains shown above, we paint the joinery in any colour from the RAL chart, more than three hundred colours, at extra cost. By prior arrangement we can also use another paint available on the market, or a finish in a different technique is also possible. We also finish internal doors with oil and wax.
