How to find the right room door
More peace, more light, more style: how to find the room door that suits your rooms. From wood to glass doors, from hinged doors to sliding doors - including decision support, practical tips and matching product pages.
The article answers 5 questions about the room door:
- What materials are available for room doors?
- What designs are available (e.g. sliding doors or swing doors)?
- What surface types are available (decor, lacquer, real wood veneer)?
- What role do factors such as sound insulation or moisture resistance play?
- How do I find the right room door for different rooms?
How "good" a room door is always depends on the area of application. How often and heavily is the door used? What role does the stability of the door play? Should the room door be equipped with a light section? Which rooms does the door connect or separate? Let's start with the material.
The right material for the door to the room
Basically, there are three materials from which room doors can be made: Solid wood, derived timber products and glass. Important when choosing the right material: what is the function of the door and which rooms it connects? Doors for bedrooms and children's rooms need good sound insulation. In the bathroom, strong resistance to moisture is required. If the door separates differently heated rooms - for example, bedroom and living room - good thermal insulation is crucial.
Wood, wood-based material or glass?
- Solid wood: warm, high-quality, good insulation; can work in damp/heat → regular air conditioning.
- Wood-based material: dimensionally stable, budget-friendly; slightly lower sound insulation.
Glass: open to light, easy to clean, suitable for damp rooms; particularly robust with ESG/VSG.
Tip: bathroom/kitchen → glass; bedroom/children's room → higher sound insulation (solid wood/corresponding insert).

Room doors: The three materials at a glance:
Room door made of solid wood
Room doors made of massive wood such as oak, beech or pine, have the advantage that they look high-quality and are particularly individual due to the wood grain. In addition, they show good sound and heat insulating properties. The disadvantage of solid wood: the wood structure can quickly warp, so that the door can no longer be closed or opened properly - because the material is quickly attacked by temperature fluctuations or humidity.
Room door made of wood-based material
Wood-based material - it can be different materials such as chipboard or fiberboard. Unlike doors made of solid wood, room doors made of wood-based materials are less susceptible to moisture in the air and therefore hardly warp, but are less sound and heat insulating.
Room door made of glass
Compared to the wooden door, these interior doors - with the exception of the handle set and hinges - are made entirely of glass. This not only visually enlarges the room due to the greater incidence of light, the doors are also particularly resistant to humidity. Since they are also very easy to clean, glass doors are well suited as bathroom or kitchen doors. For doors that are frequently used, you can opt for safety glass: Doors made of toughened or laminated safety glass withstand mechanical impact well.


The right construction for the room door
Interior doors differ not only in terms of material, but also in their construction. A distinction is made between sliding door and swing door, as well as smooth interior door and frame interior door.
Smooth room door vs. frame room door
Smooth room doors are called "smooth" because they have no visible frame. This makes them look more modern. The wooden frame is located under the surface and is covered with panels on both sides at the level of the lock and hinges. Most often, these doors are made of wood materials.
Frame interior doors, on the other hand, have - as the name suggests - a frame-like door leaf. This can be made of solid wood or wood materials. Frame interior doors are mainly used when larger glass surfaces or windows are to be inserted into a door. In addition, they offer a more traditional look, which is very popular, for example, in the country style.
Sliding door vs. swinging door
Swing doors - also called swing doors - are the most common. They open into or out of the room. By closing a swinging door, the person entering or leaving the room also closes it acoustically. The disadvantage of the swinging door: the swinging area must remain free so that the door can be opened and closed completely.
The barrier-free sliding door, on the other hand, saves space because the swing area is omitted because the sliding door "disappears" into or against the wall.
The right filling for the room door
Doors not only have a frame, but also an inner life. Depending on what the interior door is filled with, its sound and heat insulating properties and stability vary. For smooth interior doors, inserts made of honeycomb cores, tubular chipboard inserts, tubular chipboard and solid chipboard are common. Framed interior doors can be filled with solid wood, glued strips or laminate. You can find more information on the different variants in our article on door leaves.
Typical inserts (smooth interior doors)
- Honeycomb core: light, inexpensive - basic insulation.
- Tubular chipboard (insert/panel): more stable, better sound insulation, good price-performance ratio.
- Solid chipboard:maximum stability & insulation, higher weight.
Frame construction: solid wood/rod gluing - ideal for larger light cut-outs.
The right surface design for the room doo
The room door should not only open and close well, be durable as well as stable - it must also meet its own aesthetic requirements.
Decor - cheap and diverse
A foiled surface coating is easy to clean and cost-effective. Thanks to the printed foil, a particularly large number of designs are possible - from wood look to fancy geometric patterns. In addition, the decorative foil impresses with its color and light resistance. But beware: the foils are susceptible to scratches and impacts.
Lacquer - modern and easy to clean
Classic, but still on trend: painted doors. Whether matt or glossy - white doors in particular have been making a comeback in recent years. They make the room look brighter, more modern and larger. But of course, there are no limits to your color preferences. In addition, lacquered doors are particularly easy to clean. Go for a high-quality lacquer to get a hard-wearing surface.
CPL - laminate as an alternative to real wood
CPL stands for Continous Pressure Laminate - a special laminate coating that can be applied to doors. This allows you to achieve a real wood effect without having to invest in real wood. Room doors with CPL coating are suitable for particularly frequented passage doors, as they are abrasion and impact resistant and also easy to clean. In addition to a wide variety of designs and resistance, CPL surfaces also impress with the fact that they are lightfast.
Real wood veneer - individual and noble
A thin top layer of real wood - that's what real wood veneer is all about. The individual wood grain makes each door unique. This individuality also increases over time, as the wood grain and color change with increasing useful life. Real wood veneer is therefore also significantly more cost-intensive than other surface coatings.
Solid wood - classic and cozy-warm
Solid wood is and remains the classic. Since natural wood is also processed here, individual doors with interesting wood grains are created. Solid wood also contributes to a warm living climate. As long as the wood is not exposed to moisture or temperature fluctuations, the surface also remains stable and robust.
Special case glass door
You can also customize your glass door. Modern processing techniques such as screen printing or laser technology are often used here. You can find out which variant is right for you on our product overview page for glass doors. Glass doors are made of toughened safety glass or laminated safety glass. Both are robust and suitable for everyday use; laminated safety glass additionally holds loads together thanks to the film. For the look, you can choose clear, frosted or subtly tinted - depending on your privacy and style.
