One of the most versatile materials for interior decoration is drywall (gypsum board). With it, you can align the walls and ceiling, create original designs. For the ceiling, the thickness of drywall may be different from that used for other works. There is no separate concept of "ceiling drywall". This material differs in appearance, thickness.
The concept of FCL
In the 19th century, an English paper mill owner, Augustine Sackett, invented 15mm drywall as an alternative to "building board". Between two layers of construction paper, he placed a layer of hardened gypsum dough. Such material made it possible to sheathe the walls and ceilings of the premises, hiding irregularities, and to perform partitions. Depending on the work performed, the thickness of the drywall is taken into account. For a plasterboard ceiling, the sheets differ from those that cover the walls.
Types of GKL
Gypsum board differs depending on which room it is used in and for which particular structure. The main selection criteria will beproperties and scope. The difference is easy to determine by the color of the building material. GKL is usually used for interior decoration:
- flame retardant;
- moisture resistant;
Depending on the field of application, they are distinguished:
This is the most common and frequently used type of GKL. It is a classic combination of gypsum and gray cardboard sheets. Due to the relatively low weight and, accordingly, the ease of installation, it is often used when working at height. However, the use of this type is possible only in rooms with low humidity, since it no longer has additional useful properties in the form of moisture resistance. For the ceiling, the thickness of this type of drywall is a maximum of 9.5 mm. It is this GKL that can be easily processed and pasted over with wallpaper or other finishing materials. The safety of human he alth is ensured by environmentally friendly materials used in its manufacture.
Moisture resistant (GKLV)
Green outer sheets of cardboard indicate the purpose of drywall for finishing rooms with high humidity. It can even be used in bathrooms, due to the presence of specific elements that reduce the moisture absorption threshold. When using it, you should not be afraid that the material will swell, become moldy, or change its appearance. Thickness of moisture resistant drywall usedfor finishing ceilings, selected by analogy with a regular sheet.
Flame retardant (GKLO)
The third type of material is used when it is necessary to build any structure near fire hazardous objects (fireplaces, stoves). It is able to withstand high temperatures. Often this drywall is specially used in the construction of partitions in rooms in order to reduce the rate of fire spread in case of fire.
Moisture refractory (GKLVO)
The most optimal type of drywall for indoor use. But it's heavy enough. If it is necessary to sheathe the ceiling with this material, considerable force will be required. Plus, the cost of the material is quite high.
The dimensions of one sheet of drywall of any kind allow you to cover a surface of three square meters. The average weight of the sheets is approximately 30 kg. The thickness of the sheets is also different, so it must be taken into account when deciding how thick to use drywall for the ceiling.
If you want to create a real work of art on the ceiling with rounded elements, or mount it in the form of multi-level steps, you should pay attention to the arched drywall with a thickness of 6.5 mm. It is easy to bend and secure, for example, in the form of a wave.
Another commonly used type of drywall is ceiling drywall with a thickness of up to 9.5 mm. It is of medium severity among already known types and is therefore also often used for ceilings.The thickness of drywall plays a big role in choosing, as it affects the weight of the product. The thicker the building material, the heavier the sheet will be and the more difficult it will be to work with, especially on the ceiling.
The heaviest is wall drywall with a thickness of up to 12.5 mm. It is practically not used when finishing the ceiling because of its severity. Good for wall mounting and where elevated work is not required.
Thus, if you want to embody your most daring design ideas on the ceiling or just close all its irregularities, the ceiling type of drywall will remain the best choice. They also stop at it due to its low cost compared to other types.
Calculation of the required amount of drywall
How to calculate the consumption of drywall for the ceiling? Before starting construction work, it is necessary to make careful measurements and determine the area of \u200b\u200bthe ceiling. Knowing the dimensions of drywall, it is easy to calculate how many whole sheets will be needed, and how many will have to be cut. The easiest way is to take a sheet of paper, mark the area of \u200b\u200bthe ceiling on it and mark up the GKL sheets. In this case, you will immediately see how many solid sheets can be mounted.
After that, you should decide on the thickness of the sheets that you plan to purchase. If you need to perform a complex structure on the ceiling, then it is better to take lightweight building material. It will bend better, taking the required shape. It will also be much easier to lift and mount on weight than a heavier one.
In rooms with high humidity or in the presence of an open source of fire, do not skimp when buying drywall. Properly selected, it will be able to protect residents in case of fire and withstand temperature changes, lack of heating. For example, when repairing a country house.
Easy to install, suitable for many types of finishes, drywall has gained popularity since its invention almost two centuries ago. Such a ceiling will delight the eye with its grace and beauty for a long time. It is appreciated by masters of all levels, making work with it accessible even to a beginner in construction.
