15mm British Gypsum Rigidur H is the outer board component in British Gypsum's GypWall EXTREME system with increased rigidity and durability. This system is specifically suited to the varied requirements of large school and hospital projects, offering a solution with superior durability for the most demanding high traffic areas of the building. It also offers excellent acoustic performance, which is a key consideration in health and education building design. This gives you the opportunity to design the most cost-effective construction solution, both in terms of construction cost and whole life / maintenance costing for the project.

British Gypsum Rigidur H is a gypsum fibreboard which combines gypsum, cellulose fibres from recycled paper, and water, to form a dense sheet material that has superior rigidity, durability and mechanical strength. The unique surface of Rigidur H protects the boards from scratches and damage, yet is smooth enough to decorate direct without the need for surface treatments. The tough, yet smooth, surface is a result of its continuous rolling production process. They are compressed to the exact thickness required and no sanding of the surface takes place. Both the Rigidur H product and the manufacturing process have been awarded a certificate for sustainability by The Rosenheim Institute of Construction Biology and Ecology, in Germany.

British Gypsum Rigidur H characteristics

  • Extremely durable and resilient
  • Excellent fixing strength
  • Excellent resistance to vandalism
  • Tapered edge
  • Beige colour both sides
  • Conforms to EN-15283-2
  • ACTIVair technology
  • Recyclable 

ACTIVair is British Gypsum's latest technology designed specifically to convert volatile organic compounds (VOC) emissions into non-harmful inert compounds, making the air around you up to 70% cleaner. VOCs are often present in the air we breathe - emitted from furniture, carpets and building materials and long-term exposure to these can potentially cause health problems and reduce general well-being. This clever ACTIVair technology continues to work over 50 years decomposing VOCs.

Rigidur H has the fire rating of Euroclass A2 and Class 0 in accordance with the National Building Regulations. Fire resistance performances achieved with these boards will depend on the board type and thickness, number of layers, stud centres and type, fixing centres and type, and choice of cavity insulation.

The mass and sound absorbing qualities of Rigidur H enable high acoustic performance to be achieved and the performances will depend on the board type and thickness, number of layers, stud centres and type, fixing centres and choice of cavity insulation. 

The surface of Rigidur H has been treated to prevent the ingress of moisture. Tests have shown that it will increase less than 2% in thickness after immersion in water for 24 hours, and is therefore a product considered suitable for use in intermitently damp areas such as kitchens and bathrooms. If the boards become wet during construction they should be thoroughly dried out before finishing.

APPLICATION 

The boards should be stored on a firm, flat and level surface. If the boards are temporarily stored outside they should be kept clear of the ground and securely covered with an anchored polythene sheet or tarpaulin to protect from dampness and inclement weather. Individual boards can be transported for short periods stood on end, although storage on end is not recommended as boards could become permanently warped. Due to the high density and hardness of Rigidur H, it is not as easy to score and snap with a knife as Gyproc plasterboards. Best practice is to use a hand held circular saw with suitable dust extraction. Use a fine saw blade with a high ratio of teeth. 

The boards can be fixed using 40mm Rigidur screws, at 300mm centres around the perimeter of the board and at the intermediate stud positions, at least 13mm from the edge of the board. When jointing boards by hand, use Gyproc Easi-Fill. The joints can be finished using the 10& 12 Gyproc Speed Tape Finishers, if desired. Rigidur H can be skim-finished using British Gypsum Thistle Multi-Finish, Thistle Board Finish or Thistle Durafinish. The board surface may need to be treated with a coat of British Gypsum Thistle GypPrime prior to skimming, to control the suction. Rigidur H, it is recommended that Thistle Durafinish or Gyproc jointing materials be used where optimum impact and abrasion resistance is required.

Due to its smooth, hard surface, Rigidur H is suitable for all types of surface coverings, such as paint and wallpaper. The boards and their joints must be clean, dry and free from dust. Depending on the requirements of the decoration, ensure that all joints have been suitably sanded. It is recommended that a base coat of Gyproc Drywall Primer is used before finishing with two coats of good quality trade emulsion paint.

PRECAUTIONS

These boards are unsuitable for use in areas subject to continuously damp conditions and must not be used to isolate dampness. If the boards become completely saturated, it may be necessary to replace the boards. They are not suitable for use in temperatures above 49C. Mineral-based paints such as lime or silicone are not suitable.

NOTE: 15mm thick Rigidur H boards are available in different lengths. Please contact us if you need this board in other sizes.
