2x4 Gypsum Drywall Plasterboard

PRANCEgypsum plasterboards and special boards are the ultimate lining solution for today's buildings,providing high levels of performance in terms of fire rating,acoustic insulation,thermal insulation,moisture resistance to create modern internal environments that offer comfort and safety for occupant.They offer superior aesthetically inspiring solutions for walls,ceilings,lift shafts,stairwells,and corridors in buildings as diverse as residential,schools,hospitals,offices,cinemas and hotels.PRANCEis the brand of specialist high performance boards with special boards for applications like fire,acoustics,moisture,impact and themal resistance

• Gypsum contains approximately 21% water content and about 79 % calcium sulphate which is inert below a temperature of 120° C.
• Solid gypsum and gypsum rock is calcium sulphate hemihydrate, CaSO4.½H2O, produced from dehydration and re-hydration of a mineral crystal.
• The two water molecules are chemically bound with Calcium Sulphate. The bound crystalline moisture content plays a significant role in excellent fire resistance properties.
• When Gypsum is heated in fire, dehydration follows the reaction as solid gypsum starts to degrade, loses its water molecules and is eventually transformed back to the powdery material of calcium sulphate hemihydrates.
• Gypsum is known as a material of limitedcombustibility.

• PRANCE FIRE PROOF GYPSUM board is made of a paper liner wrapped around an inner core made primarily from gypsum plaster, the semi-hydrous form of calcium sulphate (CaSO4.½ H2O)
• Plaster is mixed with fiber (typically paper and/or fiberglass), foaming agent, various additives that increase mildew and fire resistance, and water and is then formed by sandwiching a core of wet gypsum between two sheets of heavy paper or fiberglass mats.
• Three key factors influence the performance of PRANCE FIRE PROOF GYPSUM :
  • The quantity of gypsum - i.e. board density.
  • Board shrinkage - preventing gaps opening betweenboards and board pulling away from fixings.
  • Board integrity - preventing boards from falling.
• The inclusion of glass fibres and shrinkage inhibitors of fire-rated products give a much higher fire protection by limiting the board shrinkage and improving the integrity.
• PRANCE fireproof gypsum board satisfies stringent international standards of fire safety and protection.
• Drywall systems using PRANCE FIREPROOF gypsum board provide passive fire resistance capabilities upto 4 hours.

At PRANCE we understand that aesthetics is not just a visual criteria. Sound, touch, and smell, are all important in the creation of "delightful" architecture. It is our constant endeavour to provide products and systems which provide architects and designers with the flexibility of designing visually appealing architecture and en hance the overall appeal of the building design.

Prance gypsum wallboard is manufactured in a continuous production process.

A gypsum slurry is made up from stucco, or plaster of Paris, water and other additives, in a continuous mixer.

This slurry spreads, in a uniform stream, from multiple outlet hoses onto a moving sheet of paper. As the board is actually produced upside down, this paper will form the front face of the plasterboard. Discs ‘score’ this paper allowing it to be easily folded at the edges. The ‘back face’ paper, fed from above the production line, is applied to the slurry via a forming head set to the desired board thickness. At this point the front face paper is folded at the edges, producing an enclosed envelope of paper slurry.

Once formed, the board travels the length of the production line on a series of setting belts, and sections of rollers to the shear. During this journey, the plaster core has time to set, or harden, and the required product information (including: product name and type, relevant British Standards, date and time of manufacture) is printed on the back of the boards via an ink jet printer.

At the shear, the long train of board is cut into panels of specific length. These smaller boards are then turned over and passed into a multi-level dryer.

During the drying period, the excess water, which was required to form the initial slurry, is gently evaporated off.

After the boards have dried, they are trimmed and stacked to form pallets.
