New options for structural compositions with RigiStabil board in timber constructions

With the new construction board RigiStabil, the brand Rigips has also brought additional construction options for timber buildings to the market. And not only there.

The RigiStabil plasterboard is used in assemblies for load-bearing and non-load-bearing partitions, false walls, ceilings, and attics in both diffusion-closed and open constructions.
Under certain conditions, it can also be used in external environments in protected exposure (soffits of roof overhangs, passages, etc.).
The excellent static properties of the RigiStabil board allow its use in load-bearing wall structures of timber buildings. The board reliably supports cantilever loads of up to 80 kg.

With a load-bearing board, it is possible to address constructions with increased requirements for mechanical and fire resistance. The hardness of the board's surface, high flexural strength, health safety, moisture resistance, and very small dimensional and volumetric changes allow the board to be used in wooden constructions and not only there. Contractors and investors will appreciate the lower weight of the board as well as its economic advantages.
Rigips is expanding its portfolio for wooden construction professionals and is introducing new structural systems clad with RigiStabil boards or in combination with Rigidur fiber gypsum boards.

Load-bearing panel with RigiStabil boards
can be used for interior load-bearing walls.

The basic modular element consists of a perimeter frame with a single central column with a maximum width of 1,250 mm.
The individual modules can be assembled into walls of any length as needed for the construction. The wall panel can be loaded with horizontal loads acting within the plane of the wall. The height of the wall must always be determined based on a static assessment.
A wall with RigiStabil boards on a wooden structure made of 60 × 100 mm studs will meet the requirements for static vertical load of 50 kN/m. A wall with simple cladding of RigiStabil boards with a thickness of 125 mm and a weight of 32 kg/m2 is classified with fire resistance REI 30 DP3, REI 15 DP2. 

Load-bearing wall panel with combined cladding for perimeter walls.

For perimeter walls, a panel with combined cladding is intended – on the inner side a RigiStabil structural board, on the outer side a Rigidur fiber gypsum board.
The basic modular element with a width of 1,250 mm is formed by a perimeter frame with a single central
column. The height must always be determined based on a static assessment. Alternatively, it is possible to perform internal cladding on horizontal battens (cross-section 30 × 50 mm, mutual spacing max. 400 mm).
A wall with combined cladding directly on a wooden structure and a panel with combined cladding from 60 × 100 mm studs also with battens will meet the requirements for static vertical load of 50 kN/m. A structure with simple internal cladding of RigiStabil boards and external Rigidur boards is classified as REI 30 DP3, REI 15 DP2.  A wall with a thickness of 125 mm and a weight of 37 kg/m² will achieve a sound insulation value of Rw = 40 dB.
The sound insulation value of the panel with battens has not been established, but it will certainly exceed the value of the panel with cladding mounted directly on the stud.

Non-load-bearing partition with RigiStabil boards on wood and metal constructions.

The basic modular element with a width of 1,250 mm consists of a perimeter frame with a single central column. The length of the wall can be arbitrary according to the needs of the construction. RigiStabil boards can be mounted on both wooden and metal constructions. Depending on the type of construction, the wall thickness varies from 75 to 125 mm, weight from 25 or 35 kg/m2, and sound insulation values of Rw = 45 or 47 dB.

Processing and installation of RigiStabil boards is easy and follows the principles for installing fiber gypsum and drywall boards.
