What is a Drywall?

A drywall is a highperformance lightweight interior wall system consisting of a GI steel frame, encased in gypsum plasterboards on either side attached with self-drilling drywall screws. The joints are then taped and finished with gypsum jointing compounds.

Drywall

Drywalls can be used to partition any interior and are the preferred choice of construction for a range of applications, in homes, hotels, hospitals, schools, theatres, and industry. They are strong and robust (drywalls of up to 15 metres high have been built) and can typically last the lifetime of a building unless they are subjected to abuse or alteration.

How to Build a Drywall
  • Step 1: Framing using highperformance Gypsteel ULTRA™ studs and channels
  • Step 2: Management of services and provisioning for planned loading
  • Step 3: Install insulation in the cavity to enhance performance
  • Step 4: Install gypsum plasterboards on both sides
  • Step 5: Do jointing and finishing on the joints
  • Step 6: Finished wall
Benefits of Drywalls
  1. Faster construction: Drywalls can be built three to four times faster than conventional masonry (brick/block) walls. Masonry construction is not only laborious, it also needs a lot of water curing. Drywall, as the name implies, is a water-free process and hence can be put up much faster, which means your project/home is always delivered on time.
  2. Ease of construction: Drywalls are easy to put up and need less labour. In masonry construction, the wall needs to be `chased' after it has been constructed to provide for services like electrical wiring. Service management for a drywall, on the other hand, is a planned activity. Service slots are provided in the system, thus making the process easy and less time consuming.
  3. Lightweight: Drywalls are eight to ten times lighter than masonry walls, reducing the dead load of the structure. This assumes significance especially in high-rise structures, resulting in not only structural cost savings, but a reduction in the burden (both ease and cost) of moving up heavy material. Studies have shown that drywalls lead to structural cost savings of as much as 15%.
  4. Flexibility: Drywalls are very flexible when it comes to creating and dividing spaces, allowing easy customisation of interiors. Their versatility allows you to maximize the usable area within a given space.
  5. High performance:
    • Acoustic comfort: Drywalls deliver high acoustic performance, capable of delivering sound insulation levels of 70dB+. Drywall systems work on the principle of mass-spring-mass. Masonry walls work on the principle of mass; every 5-6dB increase in sound insulation requires doubling of mass. Thus it is difficult to deliver acoustic comfort without increasing the thickness of the walls and consuming precious floor area.
    • Fire safety: Drywalls can be built to give fire resistance of up to four hours for stability, integrity and insulation. This means that if a fire breaks out, it will be contained to the compartmentalised area for four hours, giving occupants enough time to vacate the premises. Masonry walls are weak in insulation and integrity with the cracks forming early in the fire, leading to heat and smoke leakages.
    • Thermal comfort: The thermal insulation provided by drywalls are five times better than brick or block walls because of their low thermal conductivity (K-Value). Low thermal conductivity and high thermal resistance means lower electrical consumption as it reduces the load on air-conditioning units.

  6. Smooth finishes: Drywalls provide a high level of finish as plasterboards have paper liners on the surface that are suitable for any decoration. As a result, you get smooth, crack-free and undulation-free walls.
  7. Sustainable (green construction): Drywalls are made of gypsum plasterboard, which is 100% recyclable and has low embodied energy. Drywalls are also water-free, thus saving precious natural resources.
Different Types of Drywalls

1. Drylining System:

Gyproc Drylining provides an excellent level of finish for buildings. The lining can be used for the internal surfaces of external walls and are equally suited for both new construction and refurbishment. The wall lining enhances the thermal, sound and fire insulation of masonry walls.

Drylining can be of two types:

  • Gypliner-based systems, where an adjustable bracket is fixed to the masonry wall on which plasterboard is screwed and finished.
  • Plaster dab systems, where a gypsum plaster dab is applied across the masonry wall at uniform intervals and the gypsum plasterboard is then stuck on to it.

2. Interior Partitions:

Gypsum-based partitions are used extensively to efficiently create and divide spaces in offices. These partitions are easy and quick to build, provide excellent acoustic insulation (preventing sound from moving from one room to another), good fire protection and can take all types of finishes (from paint to wallpaper to wooden laminates and veneers). They are a superior cost-effective alternative to conventional masonry walls which take long to build and are not flexible; and wooden partitions, which pose a fire hazard, offer poor sound insulation and are expensive.

3. Performance Drywalls:

Gypsum-based performance drywalls are used to separate rooms and spaces in homes, hotels, hospitals, multiplexes and industrial complexes. Apart from offering the conventional benefits of fast and easy construction, they also offer high performance in terms of:

  • Sound insulation (50db to 70db)
  • Passive fire protection (one to four hours)
  • Strength (Severe duty)

Conventional masonry construction needs walls that are much thicker to achieve such performance, and the process is laborious and time-consuming.

4. Wet Area Drywalls:

Specialised drywall solutions are available for interior wet area applications (like bathrooms and kitchens), which use special boards like Gyproc Moisture Resistant gypsum board or Gyproc fibre cement board. These offer superior moisture resistance properties and also the flexibility to fix:

  • Ceramic tiles up to 32kg/m2 using suitable adhesive
  • Heavier marble \/granite using a combination of dry and wet fixing
