Fire-rated movable walls

For environments with high requirements of fire safety, we have developed fire-rated movable walls which meet the current European standards. Winab’s movable walls are tested and certified according to the fire classes EI-30 and EI-60.


Choice of fire wall

The building’s construction, character and use govern the fire authorities' directives, statutory fire requirements and prescribed fire class.

The Housing Board’s Building regulations summarise basic rules regarding fire protection in different environments. Folding and movable walls must, for example, influence the possibility of evacuation. There are also special requirements for surface layers.

To determine what kind of fire protection is needed in a building, the building class must first be determined, and then divided into one or more business classes. Public rooms, such as restaurants, schools and conference buildings - where partition walls are often used - are often categorised as business class 2.   


What does Winab offer?

To meet current fire requirements, Winab has developed fire-rated movable walls meeting fire classes EI30 and EI60. The classification means that the wall prevents fires for up to 30 or 60 minutes, respectively. 

Choosing a fire-rated folding wall means a guarantee that the wall meets the set fire requirements. With this classification, the customer can also compare Winab's walls with competing products.


Norms and requirements

Who sets the rules of the game?

Fire protection classes summarise the requirements in terms of fire protection properties for various construction products. Fire-rated products are, through design and material selection, built to prevent the spread of fire and slow down temperature increases.

All buildings must have technical fire protection, but the extent of the requirements depends on the nature of the building and the activities taking place in the premises.

The basic requirements for safety in the event of a fire are found in the Planning and Building Act, PBL. The law applies to all types of construction works, i.e. buildings or other facilities. 

The law is interpreted and clarified in the Housing Board’s Building regulations, BBR, which contains rules on fire protection and describes the minimum requirements both for the construction of new buildings and for the alteration of existing ones. In BBR section 5, binding regulations and general advice are given. 

The fire class specifies the requirements for fire protection and the functions that the finished building must have. Based on these requirements, however, the client can choose products, materials and constructions that meet the basic requirements.

Fire classification of Winab's folding walls

In terms of folding and movable walls, the relevant classification bases are Integrity (E) and Insulation (I), i.e. the wall's preconditions for preventing the spread of fire. 

Integrity (E) against fire is a tightness requirement which means that fire in the form of stab flames and the like does not penetrate the construction. The E-requirement must always be met and can be used as an independent class such as E30.

Insulation (I) is a requirement for maximum temperature increase on the non-fire side of 140C˚ and of 180C˚ in individual points. The I-requirement is always combined with the E-requirement and cannot be used independently.

Winab’s movable walls meet the requirements of Fire Class EI30 and Fire Class EI60. The classification means that the construction can withstand a fire for 30 or 60 minutes. 

The movable walls consist of easily movable wall elements for simple and flexible division of larger and smaller premises.

Movable walls are made of aluminium profiles covered by surface-treated boards, intermediate insulation and sound-absorbing materials. All walls are manufactured according to the customer's wishes in terms of dimensions, section division and surface treatment.


Thickness 100 or 110 mm depending on requirements for sound or fire classification.
Weight/m² 50 or 63 kg, depending on sound reduction requirements or fire-rating (incl. rails and mounting accessories)
Section width Minimum 400 mm / Maximum 1200 mm
Height Maximum 6000 mm (higher upon request) Fire certificate applies to height up to 3500
Colour/surface treatment According to request
Sound reduction EI30 Rw 46dB, EI60 50dB

Assembly guide

WINAB’s folding walls are easy to assemble. The walls are developed completely based on the client's requests regarding measurements, sectioning and surface treatment. All movable walls are ceiling-suspended, which eliminates the need for floor rails and always provides clean, free floor spaces.

The wall blocks have telescopic seals in the top and bottom edges and can be purchased as single- or two-point suspensions depending on parking requirements. Two-point suspended movable walls offer completely hidden parking, where the wall blocks can be parked in our outside the premises. For good and tight function between floor and wall, the floor must be level.

If any problems arise with the mounting process, please do not hesitate to contact us.

Assembly guide WINAB 2000 movable walls

The movable walls consists of sections which hang in a carrying rail. The sections are attached between the carrying rail and the floor. Floor rails do not occur. The movable walls may be either single-point or double-point suspended with 1 or 2 carrying walls, respectively. If the wall is double-point suspended there is a garage. A single-point suspended wall does not have a garage.

  1. Measure the closing line. Make sure that the wall has the same measurements.
  2. Measure space for garage. The garage must fit in the intended space. The garage may not be cut. The straight pieces can be delivered oversize. Never cut shorter than the closing line on the drawing.


  1. Drill screw holes at appropriate distance.
  2. Screw in the garage from below according to the rail drawing.


  1. Drill screw holes at appropriate distance.
  2. If necessary, cut to the dimensions specified in the drawing.
  3. Screw in the rail from below according to the rail drawing. NOTE! Save the last rail piece until the sections have been hung in place.
  4. Use the included clips in the rail joints.


  1. The sections are hung by the carrying rail in the order indicated in the accompanying drawing.
  2. Screw in the last rail piece.
  3. The frames are mounted in place with a sinker under the roof rail.
  4. The carrying trolleys are adjusted so that the sections are centred between floor and ceiling, after which the lock nuts are tightened. (Key 24, 18 and 13 mm).
  5. Attach with seam to wall and ceiling to ensure a tight installation.
  6. Follow the Operation & Maintenance Instructions to verify the function of the wall.


Hidden parking when the wall pieces should not be seen

Movable walls are always delivered as ceiling-suspended. The wall blocks have telescopic seals in the top and bottom edges and can be purchased as single- or two-point suspensions depending on parking requirements.

Two-point suspended walls offer the possibility for a completely hidden parking, in or outside the premises.

The parking alternatives below are only some examples of how movable walls may be parked. The parking options are much more extensive than that and very flexible depending on requests and the conditions the premises offer.

The parking alternatives K1, Z1, E1 and to some extent K4 are the most popular, while options K3, K5, K6 and Z2 are more to be considered as special solutions.

Parking options


Parkeringsalternativ K1
Small, compact parking Two-point-suspension where one wheel pair runs along the closing line. A parking option which is suitable when one side of the movable walls is blocked in some way or when it may be difficult to find attachments outside the closing line.


Parkeringsalternativ K3
A parking option where the wall segments are parked beside/behind a protruding wall. The parking cannot be considered "hidden", but the wall segments will still have a certain hidden placement when the room is to be used fully – without the movable walls.


Parkeringsalternativ K4
The wall segments are parked in a niche outside the closing line. Here it is also possible to create a hidden parking by putting a niche door that completely hides the wall segments when they are parked.


Parkeringsalternativ K5
An example of parking where a protruding wall is used to align several parking sections and a larger amount of wall segments of a relatively long closing line.


Parkeringsalternativ K6
Niche rotated 90°. The wall segments are parked outside the closing line and, just as in K4, there is also here a possibility to create a hidden parking by placing a door over the niche.


Parkeringsalternativ Z1
Perhaps the most common two-point-suspension of movable walls. The suspension is relatively simple to mount and preferred in comparison to K1, which requires a few more handling steps when closing, opening and parking the wall.


Parkeringsalternativ Z2
A parking alternative where the wall segments protrude less next to the closing line in comparison to, for example, Z1.


Parkeringsalternativ E1
A single-point-suspension movable walls where the wall is mounted at the centre of the closing line. The parking is simple and uncomplicated to mount.
