A drywall is a high performance 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.
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.
Advantages of Drywall
Benefits of Drywalls
Drywalls consume 95% less water than masonry construction.They can be built three to four times faster than conventional masonry (brick/block) walls and 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 home project is always delivered on time.
Speed of installation
Drywalls are easy to put up and need less labour, to be precise, drywalls can be executed 3 to 4 times faster than masonry construction. 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.
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%.
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.
Acoustic comfort: Drywalls deliver high acoustic performance, capable of delivering sound insulation levels of 70dB+ as they work on the principle of mass-spring-mass. Masonry walls work on the principle of mass making it is difficult to deliver acoustic comfort without increasing the thickness.
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.Thermal comfort: The thermal insulation provided by drywalls is 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.
Seamless and crack free surfaces, allowing ease of decoration via paint, tiles or wallpaper. 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.
Green Product which is recyclable and is made of environment friendly material. 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
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.
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.
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)
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 adhesiveHeavier marble \/granite using a combination of dry and wet fixing
Closed Stud office partitions
Gypsteel Ultra Closed Stud & Gyproc Gypsum board based partitions are used to efficiently create and divide spaces in offices. These Partitions can replace the old-fashioned Aluminium framing based partitions. Gypsteel Ultra Closed Stud & Gyproc Gypsum board based partitions provide several advantages over Al framed partitions such as Gypsteel Ultra Closed stud partitions can provide fire rating up to 2 hrs. whereas Al partitions can not provide any fire rating. Gypsteel Ultra Closed stud partitions provide better acoustical insulation (50 dB) than Al framed partitions (44 dB). Gypsteel Ultra Closed stud partitions proper spacing for screws and staggering of joints for boards. Thus result in more stable and durable partitions.
Installation video drywall
J.W. Marriott is a 5 star luxury hotel with 550 rooms located just outside the T3 airport terminal in New Delhi. The key requirement for this project was a system which would help in constructing the project faster, with walls that delivered high performance in terms of acoustics and fire rating.
Can Gyproc drywalls walls be used for external walls?
Gyproc's gypsum plasterboard based drywalls are suitable only for interior applications (including shaft and bathroom walls).
How is a drywall more efficient in terms of accomodating and managing services?
Once a conventional masonry wall is built, a service contractor comes and chases (breaks) the wall to put in the services (electrical wiring, pipes etc.). This is time-consuming and also destroys the finish and integrity of the wall. This is also often the point of failure of the wall in terms of leakage of sound and fire.
In drywalls, the vertical element called "stud" has cut-outs for services to pass through. All electrical and plumbing work can be accommodated inside the drywall without hassle. The sequential process of building drywalls is such that the boards are fixed only after the services are installed, saving time and ensuring that the wall integrity and finish is retained.
What surface decoration can be done a drywall?
Drywall is faced with gypsum plasterboard which has special paper on the surface. This allows for smooth, crack-free finishes. All kinds of decorative materials like paint, wallpaper, tiles, veneers and laminates can be used on a drywall to give the desired finish.
How strong are drywalls?
Drywalls can be built as strong as you want and are typically strong enough to take the requisite abuse of a normal application. Gyproc offers special boards for higher strength applications, like Gyproc Duraline, a high-density gypsum plasterboard that offers a high level of impact resistance (severe duty rated according to BS5234). For very high abuse resistance, there are paperless gypsum plasterboards like Gyproc Rigidur which offer higher loading strength.
How can one fix an unplanned load on a drywall?
We recommend planned loading for heavier loads. For lighter loads, unplanned loading is possible, similar to that employed with masonry construction. The only difference is that special kinds of screws called cavity toggles are used. There are different kinds of cavity toggles with different point loads capacity. So anything from a plasma TV to a picture frame can be fixed on a wall using this technology.
