Yes. You should always protect your head while on building site.
No, if you cut the boards by “score and snap” method. Yes, if you are using dust producing power tools without dust extraction equipment.
Only lift what you feel you can manage. For carrying the whole board, seek assistance of the second person. Carry the board in a vertical position and in balanced manner. Work together in timing.
All wall and ceiling systems offered to market by Mada Gypsum Company have been tested or assessed and their performance is declared when Mada boards and Mada approved components are used. Mada Gypsum Company cannot support such system performance or warrant the materials if Mada boards or Mada approved components are substituted with material supplied by another manufacturer.
Fire resistance of a material cannot be expressed. Fire resistance is not defined just on the board itself, it is defined on the construction part, e.g. partition or ceiling.
For wet areas including bathrooms, showers, kitchen, laundries and ceiling applications such as walkways and verandas we recommend Mada MR or FMR plasterboard. For high moisture areas Mada PROCEM boards are recommended.
Mada Moisture Resistant plasterboards (MR or FMR) or PROCEM cement boards, subject to conditions.
The surface temperature of the plasterboards may not exceed +45°C for a long
Use Mada Shaft Wall system. Please refer to section 6.5 in Mada Installation Manual.
Use Mada AC board and cavity insulation within a Mada wall lining system. Selection depends on a number of factors such as type of background, height of lining and performance requirements. Please refer to section 6.2 and 6.3 in Mada Installation Manual.
Wall lining fixed into the structural wall does not have a height restriction. Wall lining free standing is limited by height – for further information please refer to e-Selector or section “Wall linings” in Mada System Book.
Use the e-Selector and linked Technical Data Sheets on this web page, or look into Mada System Book.
Please, refer to Mada systems section on this web page or to Mada literature or contact Mada Technical Support.
There are basically two systems available: Wall lining fixed into the structural wall and Independent free standing Wall lining. Selection depends on a number of factors such as type of background, height of lining, performance requirements and board type. Please refer to e-Selector on this web page or contact Mada Technical Support.
The breaking load of your fixing point should be minimum 1.2 kN (about 120 kg) regardless of the suspended ceiling assembly.
When hanging or attaching an object to a wall, always make sure the local load bearing capacity of the board and the overall capacity of the wall itself is not exceeded. Lightweight objects may be fixed directly into the board. Their allowed weight depend on the overall thickness of the boarding and the fixing element used. Heavy or heavily loaded objects (i.e. sanitary installations as wash basins, sinks or toilet bowls, pipeline fixtures and fittings) have to be fixed independently into the construction grid through additional construction member (i.e. special sanitary ware frame, plywood insert plate fixed to the studs, etc.). For further information, please refer to section 3.8.1 Mada Installation Manual.
Lightweight objects up to 6 kg/point may be fixed directly into the board. Heavier objects up to 10 kg/point and/or 20 kg/m2 have to be fixed into the grid. Objects over 10 kg/point and/or 20 kg/m2 have to be fixed directly into the structural soffit.
Plasterboard fixed to steel framing is typically sheeted vertically. The longitudinal joints between the boards are easier to be finished. As the boards can be of room height, this reduces the number of horizontal (transversal) joints.
Select the Steel Self-Piercing Tapping Screws to up to and including 0.8mm basic metal sheet thickness. Use Steel Drill Drywall Screws for fixing to the framing over 0.8mm basic metal sheet thickness. The length of the screw should be selected so that the screw gives a nominal 10mm penetration into the metal.
Drive the screw head into the plasterboard so that it embeds slightly below the surface, but without cutting through the paper liner. The screw should not protrude above the surface of the board.
Yes. The studs bordering the opening need to be stronger to support the weight of the door and forces caused by door slamming etc. Typically this would involve either boxing the C studs or sleeving them with U channel, or inserting a timber insert.
By “splicing” two studs together. The C studs are boxed in sufficient length or overlapped (sleeved) with the length of U channel and screw-fixed together. Please refer to drawing No. ... in Mada Installation Manual.
A control (expansion) joint shall be installed where a partition wall or ceiling traverses a construction joint (expansion, seismic, or building control element) in the base building structure. In other cases - Control joints in interior walls shall be installed where a wall or partition runs in an uninterrupted straight plane exceeding 9.1m. - Control joints in interior ceilings without perimeter relief shall be installed so that linear dimensions between control joints do not exceed 9.1m and total area between control joints does not exceed 80 m2. - Control joints shall be installed where ceiling framing members change direction. - Control joints shall be installed where specified by the architect or designer as a design accent or architectural feature. - Where a control joint occurs in an acoustical or fire-rated system, blocking shall be provided behind the control joint so that the required performance is not compromised. The applicable standard is ASTM C 840.
Conduits and pipes can easily be accommodated within the cavity of the Mada systems. The maximum outside diameter of the piping depends on the size of the studs (at least 10mm space between the outside diameter of the pipe and the internal surface of the board should be maintained). Conduits and pipes should be fixed to the framing with care to prevent vibration noise. The installation of electrical services should always be carried out in accordance with the requirements of the respective technical standards and building codes. The studs either have cutouts or push-outs to accommodate routing of electrical cables. Grommets or isolating strips should be installed in the cut-out to prevent cutting or abrasion of the cables.
Generally yes. The drywall primer seals the board, equals the water absorption of the paper and jointed areas and creates an even texture ready to receive decoration. The priming is not needed if the boards are going to be finished with a skim coat or plaster.
For slight damage to plasterboard where just the paper surface has been scratched or dented, but there is no damage to the gypsum core, the damage should be rubbed down lightly with fine sandpaper and the area filled with Mada Jointing compound to bring the surface flush. In those cases where the board core is damaged, the rectangular part of the board has to be cut out and replaced. The replacement piece of boarding is then supported by a length of metal profile slid behind the lining and fixed into the void by screws driven through the board lining around the cutout. The new replacement board is then jointed, taped and finished to final surface.
