Gypsteel Ultra Closed stud partitions provide better acoustical insulation 50 dB than Al framed partitions 44 dB. Drywall construction became prevalent in North America as a time and labor saving alternative to traditional lath and plaster. Water that enters a room from overhead may cause ceiling drywall tape to separate from the ceiling as a result of the grooves immediately behind the tape where the drywall pieces meet becoming saturated.

Drywalls are also water-free, thus saving precious natural resources. These partitions are easy and quick to build, provide excellent acoustic insulation preventing sound from moving from one room to anothergood fire protection and can take all types of finishes from paint to wallpaper to wooden laminates and veneers.

This is also often the point of failure of the wall in terms of leakage of sound and fire. Recycled paper is typically used during manufacturing. The board is then formed by sandwiching a core of the wet mixture between two sheets of heavy paper or fibreglass mats.

Type C gypsum panels provide even greater fire resistance than Type X. As downward deflection of the drywall assembly and buckling towards the fire occurs, the top of the firestop is squeezed and the bottom of the firestop is pulled.

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. In response to the new supply of this raw material, the gypsum board market was predicted to drywaall significantly. Apart from gypgoc the conventional benefits of fast and easy construction, they also offer high performance in terms of: The issue was resolved in and now all drywall must be tested for volatile sulfur and any containing more than 10 ppm is unable to be sold in the US.


It is, therefore, counterproductive to suspend penetrants from the drywall assembly during a fire test.

gyoroc 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. From Wikipedia, the free encyclopedia. Plasterboard is commonly made with one of three different edge treatments: Cosponsored tests result in code recognized designs with assigned fire-resistance ratings.

hyproc One coat gyoroc plaster over dry board is an intermediate style step between full multi-coat “wet” plaster and the limited joint-treatment-only given “dry” wall. This is provided that the material used in the field configuration can be demonstrated to meet the minimum requirements of Type X drywall such as an entry in the appropriate category of the UL Building Materials Directory or in the Gypsum Association Fire Resistance and Sound Control Design Manual and that sufficient layers and thicknesses are used.

The gypsum construction handbook.

This section needs additional citations for verification. A wallboard panel consists of a layer of gypsum plaster sandwiched between two layers of paper.

All kinds of decorative materials like paint, wallpaper, tiles, veneers and laminates can be used on a drywall to give the desired finish. Gypsum will soften with exposure to moisture, and eventually turn to a gooey paste with prolonged immersion, such as during a flood. Veneering uses a slightly different specialized setting compound “finish plaster” that contains gypsum and lime putty. Drywall provides a thermal resistance R-value in US units of 0.

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.

All electrical and plumbing work can be accommodated inside the drywall without hassle. Blueboard also has square edges rather than the tapered-edge drywall boards. To simulate the drywall deflection effect, one can simply mount the penetrants to the steel frame holding the test assembly.

Sound insulation 50db to 70db Passive fire protection one to four hours Strength Severe duty. An alternative to traditional wood or metal lath, it was a panel made up of compressed gypsum plaster board that was sometimes grooved or punched with holes to allow wet plaster to key into its surface. However, four-side chamfered drywall is not currently offered by major UK manufacturers for general use. Some manufacturers take back waste wallboard from construction sites and recycle it into new wallboard.


How is a drywall more efficient in terms of accomodating and managing services? It is, therefore, important to test firestops in full scale wall panel tests, so that the deflection of each applicable assembly can be taken into account. In some applications, the drywall may be attached to the wall with adhesives. There is potential for using crushed drywall to amend certain soils at building sites, such as sodic clay and silt mixtures bay mudas well as using it in compost.

Drylining can be of two types: Penetrants may increase in length, push and pull as a result of operational temperature changes e. 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.

Olson Gypsum Archived at the Wayback Machine. If the penetrants are mounted to and hung off drjwall drywall assembly itself during the test, this does not constitute a realistic deflection exposure insofar as the firestop is drywa,l. Wikimedia Commons has media related to Drywall. Drywall panels in the United States are manufactured in inch 1.

This makes drywall an ablative material because as the hydrates sublime, a crumbly dust is left behind, which, along with the paper, is sacrificial. They are a superior cost-effective alternative to conventional masonry walls gypgoc take long to build and are not flexible; and wooden partitions, byproc pose a fire hazard, offer poor sound insulation and are expensive. 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 addition to increased R-value, thicker drywall has a higher sound transmission class. Generally, exposure of drywall on a panel furnace removes the water and calcines the exposed drywall and also heats the studs and fasteners holding the drywall.

For very high abuse resistance, there are paperless gypsum plasterboards like Gyproc Rigidur which offer higher loading strength.
