The metal stud partitions are strong, high perfofrmance systems which are cost effective, lightweght, versatile, quick to erect and able to achive high levels of fire resistance and acoustic insulation. They are suipable for general commercial and domestic use. The metal stud construction from UW track and CW stud profiles made of steel galvanized tin is single or double planked with gypsumboards, which means that each side is planked with one or two layers of gypsumboard. As insulation material for all the hollow spaces is used glass or rockwool RIVATHERM. High fire and moisture resistance could be acheived by using cement fiber boards BETOPAN.

Advantages

  • Flexible space distribution: with the metal stud walls in fact there are no limits with the distribution planing. Even if there are later space distributions the stud walls could be put on any place and if necessary they could be disassembled.
  • Quick finishing: right after the installation the joints between the boards are filled. The dry and smooth wall surface could be immediately painted or covered with wallpapers. The wall cavities are an ideal chance for putting any kind of installations inside them. The installations’ work is at the same time with the system installation.
  • Heat insulation: the gypsum construction materials have great heat insulation capabilities. In the stud walls the insulation characteristics of the materials are perfectly presented. The wall surface quickly adopts to the temperature inside the room.
  • Fire resistance: the gypsum is non-flammable material. With the metal stud walls all fire resistance acquirements will be kept.
  • Sound insulation: the effective sound insulation is a precondition for coziness and high quality of the dwelling. The stud walls offer sound insulation typical for thick heavy walls.
  • Depending on the type of the construction the weight of the most common stud walls is from 25 to 50 kg/m2

  • The axis of the partition are marked over the floor and the surrounding walls. With a carpenter’s level and a straight slat the wall’s axis are marked on the ceiling.
  • The profiles are cut with a tin scissors. For continuous thick connection between the border construction elements and the connector profiles joint tapes are used.
  • Over the markings on the floor and ceiling the UW50, UW75 or UW100 track profiles are fixed. They should be fixed with a dowel with a screw pin fastener at an 80-cm distance.
  • The main CW50, CW75 or CW100 stud profiles are placed in the UW runners at a distance between the axis 60cm and are leveled with a level.
  • After that the furring of the first wall with a whole board begins. The boards are screwed to the CW stud profiles with self taping screws at a distance not more than 25cm.
  • The installation work is done. The cavities offer enough space. In the basement of the CW stud profiles holes are drilled for installations. More holes could be made if needed. For electric switches and plugs special boxes for hollow walls are used.
  • For heat and sound insulation special material is used.
  • After all this the second side of the wall is furred commencing with half of a board. In this way the joints between the boards are moved.

    After hanging your drywall, you’re ready for the most critical part of the drywall installation process,- taping and finishing the joints between wallboards

    Finishing drywall has three steps to it:

    1) Filler Coat:The surface of the boards is cleaned and the joints are filled with jointing compound DERZTEK. It is strongly recommended the usage of glass fiber joint tape, no matter the type of the joint filler. This increases two times the strength of the connection and is the best protection against cracks. When dry, the surpluses of jointing compound are removed with sandpaper. Sand with 120 or 150 grit Sanding Paper.
    2) Second Coat: The joints are coated and sanded a second time 24 hours after the first coat.
    3) Finish Coat: After another 24 hours, for perfectly smooth surface SATENTEK might be used. If done properly, this last coating should have no need of sanding.

    Tip: In order to work from easiest joints to hardest, follow this order for applying the joint compound: start with nailheads, then valley joints (the longitudinal joints), inside corners, outside corners, and lastly the butt joints.
