What is Plasterboard?
Plasterboard consists of calcium sulfate dihydrate (gypsum) usually pressed between a facer and a backer. Walls are constructed from it and interior doors are also made from it. Plasterboard is primarily used for partitioning, lining walls, and constructing ceilings in any type of building, from schools and hospitals to schools, shops, and residences. External sheathing can also be achieved with newer, more innovative plasterboard products.
The rise of plasterboard began during the end of the 1910s and throughout the 1920s. The use of plasterboard tape is a good way to finish off a wall although wet plastering is quite common in the building industry.
Types of plasterboard
The best plasterboard fixings will depend on the plasterboard you choose. Plasterboard fixings are used to hold drywall in place.
Water Resistant Plasterboard
In bathrooms and kitchens, moisture-resistant plasterboard should be used. The external soffits of your house might also be installed with this type of plasterboard.
To prevent moisture accumulation on the wall, water-resistant drywall contains additives. In the core of the plasterboard, these additives are found.
A bathroom or kitchen installed with the wrong type of plasterboard could be vulnerable to water damage. As a result, the drywall could weaken and deteriorate over time.
Insulated Plasterboard
Thermal plasterboard or insulated plasterboard is a popular type of drywall. Designed to prevent heat from escaping. A plasterboard can keep heat in by being attached to a thermal insulation board.
Combined, they form insulation plasterboard. Using insulated plasterboard to insulate your walls can also save you money.
Acoustic Plasterboard
A plasterboard that minimizes sound transmission between rooms is called acoustic plasterboard. Often, this type of soundproof plasterboard is denser than most drywalls. In a given room, it reduces noise.
Sound travels through a ceiling and walls less effectively when the ceiling and walls are made of acoustic plasterboard. The thickness is 12.55mm. Reinforcing it with soundproof materials such as mineral wool or fiberglass can improve its sound insulation capability even more.
Fire Resistant Plasterboard
Fire-retardant plasterboard has a fire-resistance rating that changes depending on which product you choose.
There are many types of fire-resistant plasterboard, some of which are completely fireproof while others are resistant to catching fire for several hours. Plasterboard that is fire resistant should have a minimum resistance time of 30 minutes to 2 hours.
Fireproofing is achieved through the use of glass fibers and other additives
Impact Resistant Plasterboard
Physical damage can be reduced or avoided by using impact resistant plasterboard. Due to its high density and the addition of various additives, its durability, strength, and load-bearing capacity are enhanced.
To determine the performance of such plasterboard, the British Standard BS 5234 is used. Based on these measures, you should look for impact-resistant plasterboard that has a high rating.
What is the difference between drywall and plasterboard?
Plasterboard, also known as drywall, is made up of gypsum mixed with water and spread between two large sheets of paper. Walls and ceilings are constructed with Drywall. The plasterboard is installed by lifting the pieces and attaching them to the wall studs.
How can you tell if a Wall is Plasterboard?
Plasterboard walls can have a wood or steel frame. In general, this runs vertically at regular intervals between 300 and 600mm, with short horizontals or “noggins” between each. Almost all plasterboard walls sound hollow and move a little bit when you knock on them.
How Thick is Plasterboard?
We will be discussing the thickness of plasterboard for this section. The thickness of plasterboard is generally 9.5mm or 12mm. Plasterboard is available in different thicknesses, however.
The use of thicker plasterboard can provide insulation, protect against damage or reduce noise transmission between rooms
It is possible for fireproof plasterboard to have a thickness of up to 15mm. The ideal thickness of plasterboard for the walls and ceilings of a room can also differ.
How Much Weight Can Plasterboard Take?
Plasterboard's load-bearing capacity should be considered before purchasing. We will discuss this and look at topics such as the weight that a nail in drywall can hold.
Most plasterboard walls can hold around 20kg/m2 of weight, although it varies depending on the type of plasterboard you buy.
You can only put a few kilograms of weight on a nail in drywall. Plasterboards made from certain materials will have greater strength.
According to their design, some plasterboard products can hold more weight than others. Additionally, the plasterboard's thickness and size will affect how well it supports loads.
What are plasterboard screws?
Black screws with countersunk, pozidriv heads are generally found in this category. Depending on the thickness of the plasterboard, different lengths of plasterboard screws should be used.
The screws should be 32mm long if the drywall is 9.5mm thick. If your drywall is 12.5mm thick, use screws 38mm long.
Screws used on plasterboard differ from other screws. Case-hardened steel is used and they are specifically designed for plasterboard construction.
How to Cut Plasterboard
The plasterboard is best cut with a plasterboard saw. A straight edge, Stanley knife, pencil, and measuring tape are required.
Wallboard saws can also be used as plasterboard cutters when cutting out shapes from the middle of a board.
Wearing cut-resistant gloves is a good choice of safety equipment. Mark carefully the line or lines you wish to cut on the plasterboard with a pencil and straight edge before commencing cutting. Then, if necessary, use a plasterboard plane or rasp to smooth out any imperfect cuts.
The plasterboard must be cut correctly in order to avoid drywall damage or to make a sufficiently thin cut.
The dot and dab method is a popular way to install plasterboard. Read our full guide on how to dot and dab plasterboard
