Interior Sliding Door Systems


Interior Sliding Doors

Our most popular door system - sliding doors can be configured in multiple ways and are available in either “Bottom Rolling” (with floor tracks) or “AIR” (without floor tracks). Configuration and door size typically determines if AIR doors can be used. During a phone consultation, we’ll discuss the best options available for your project. Whether you have a closet or pantry that needs to be enclosed, a single bedroom or bathroom entry, or you need to create a space within a space using a wall-to-wall room divider or a corner solution - sliding door systems offers many options and versatility to meet your requirements. Click on the below configuration icons for more information.



Fixed Panels with Sliding Doors

When a wide opening requires a lock or inoperability is desired, a possible solution exists by combining a sliding door with one or more fixed elements. The fixed element remains stable by resting on a baseplate mounted to the floor and a connection profile mounted to a wall or post. Infinite number of fixed elements can be joined inline to create an inoperable wall.  



Fixed Panels

Sometimes light transmission is desired or operability isn’t required. Fixed panels are a perfect solution. The fixed element remains stable by resting on a baseplate mounted to the floor and a connection profile mounted to a wall or post. Infinite number of fixed elements can be joined inline to create an inoperable wall. 



Bi-fold Doors

A perfect door system for narrow opening widths where maximum opening clearance is desired for full accessibility. Best used for pantries and closets that utilize interior shelving and drawer components or where a washer and dryer requires full accessibility. Bi-fold doors can be installed as one pair (two leafs) or two pairs (four leafs) within a single opening. 



Hinge Doors

Another option for narrow openings and best used in light-duty use areas. Hinge doors can be installed in a double door configuration and can be combined with Bi-fold doors within the same opening. Hinge doors can also be mounted to cabinetry.

AIR System

AIR sliding doors utilize a small floor guide rather than a floor track. The load-bearing weight of the door is transferred to the top track and ultimately the ceiling or wall, depending on top track mounting method. Any door exceeding 130 lbs will require the use of floor tracks.

Bi-Fold System

The S34 Folding door system offers folding doors up to 5′ wide by 9′ tall. Folding doors are the perfect choice when space is limited and full access is needed. The S34 Folding door system is available in Made-to-Measure frame kits or fully finished doors – including a large variety of panel materials. S34 folding door system is offered in the S300 Asymmetrical profile and is ceiling-mount only.

Hinge System closet doors




The raumplus interior door systems consists of FOUR distinct door system types:

Sliding - Fixed - Bi-fold - Hinge


Within each door system type, various configurations are possible. For example, our sliding door systems can be configured as pocket doors, bypass doors, barn doors etc. Configuration is largely determined by your desired functionality and end goals. We’ll help you determine what configuration is possible and best suited for your project.

S42 or AIR

Whenever you see S42, this refers to the depth (thickness) of the door stile (vertical frame profile of the door) in millimeters. (Imperial conversion: 1-5/8”) and S42 is the family name for our bottom rolling systems. AIR in contrast, is the family name for our top hung sliding door systems.


In each system type, various door stiles (shapes of the vertical door frame profile) are available. For example, sliding door systems use either S1200, S1500 or S3000 profiles. Each profile has various reasons for why one may be used over another - aesthetics and functionality being two examples. See Systems Overview matrix below to determine available profiles within each system.
