Many apartment owners, like the owners of country houses, do not know which drywall is best to use for the ceiling.
Suspended structures made of this material are still the most affordable, practical and versatile option. There are several types of drywall on the market. But it is important to choose the right not only the main material, but also profiles, fasteners, and other little things that directly affect the quality of the structure as a whole.
Key Benefits
Drywall is a sheet material. It can be used for various construction and finishing works, but most often it is used to make structures such as suspended ceilings. This is due to the advantages of the material itself.
The best plasterboard ceilings are systems that allow you to completely transform a room. This is an environmentally friendly material with which you can get a neat ceiling at minimal cost. It also has good soundproofing properties.
At the same time, if the area of \u200b\u200bthe room and the height of the ceilings allow, you can createstructures of various shapes. So you can mask the flaws in the layout, make the design more interesting. And, of course, such designs are a practical solution for any room.
It remains only to decide which drywall is better to use for the ceiling. After all, manufacturers produce both fire-resistant and moisture-resistant sheets. The latter are especially relevant for the kitchen, as it is characterized by high humidity.
The choice of material is of fundamental importance. It may develop cracks if its thickness and other parameters do not meet the requirements of the ceiling finish.
Views
When the question arises of which drywall is best to use for the ceiling, many begin to look for some special sheets. But in fact, drywall is divided into wall and ceiling versions conditionally: ceiling sheets have a smaller thickness and weight, so it is believed that such material is more suitable for creating appropriate structures.
It is much more important to decide on the type of product. To find out which drywall is better to sheathe the ceiling, you need to consider standard sheets, as well as moisture and fire resistant options.
GKL and their properties
The simplest type is standard drywall sheets. They are a layer of gypsum, having the same thickness in any area, which is covered on both sides with a special building cardboard, which in this case acts as a reinforcing frame. In addition, it is also the basis on which the finishing will be applied in the future.material.
GCR is produced with a width of 1, 20–1, 25 m. But the sheets can have different lengths - 2, 2, 4, 2, 6, 3 meters, etc., that is, you can purchase any suitable model.
Moisture resistant sheets (GKLV) and their features
Moisture-resistant plasterboard sheets (GKLV) can also be found on the market, which are distinguished by a greenish tint of cardboard. Silicone granules and antifungal components are added to the composition of gypsum for such products.
Of course, if the neighbors from above make a flood, then such sheets will not save. But in general, they are less sensitive to high humidity than classic drywall products. In addition, when deciding which drywall is better to use for the ceiling, you need to remember that the properties depend not only on the sheets themselves, but also on additional finishes. For example, in the case of GKLV, moisture-resistant paint, appropriate varnish or ceramic tiles are required. This material is suitable for finishing the ceiling in the bathroom, bathroom, kitchen and even in the garage.
Fire resistant drywall and its properties
There are also fire-resistant drywall sheets on the market, which are abbreviated as GKLO. For their destruction, higher temperatures are needed than for standard sheets. Such characteristics are due to the addition of fiberglass to the gypsum, which makes the material more fire resistant.
This is the most expensive type of drywall. In residential buildings, it is practically not used. However, hisoften used in industrial premises where fire safety requirements are much higher.
Drywall thickness
It is important to decide what thickness of drywall is best for the ceiling. Everything, of course, depends on the specific project and the load that will fall on the structure. But you need to take into account the fact that drywall sheets also create a load for the draft ceiling and ceiling.
Standard drywall sheets can be 9mm or 12.5mm thick. The second variety is considered wall, and the first - ceiling. There are also panels with a thickness of 24 mm on the market. But they are definitely not used for residential ceilings.
Thickness 9 mm is an indicator for basic elements. For decorative figures, even thinner sheets are used - 6 mm.
Edging types
Edging matters for any drywall finish. For the ceiling, they are just as important.
The following options are distinguished:
- Straight edge. PC is marked and is considered the best option for the so-called dry installation. However, it is only suitable for those cases where the drywall layer will not be the top in this design, that is, putty is applied to it.
- Thinned hem. Marked as UK. It involves the use of reinforcing tape at the end of installation work and the application of putty.
- Rounded hem. Designated as ZK, generally similar to the previous view, but it does not use reinforcing tape.
There are also varieties of semicircular edges - PLC (on the front side) and PLUK. ATin the first case, there is only one side rounding, reinforcing tape is not needed. In the second option, you definitely need to use tape and treat the surface with putty.
How to choose a profile?
Many do not understand which profile is best for a plasterboard ceiling. There are two main types - CD and UD. Actually, the letter D just says that this is a ceiling profile.
The UD profile is characterized by such parameters - the width and height are the same, 25 mm, the length can vary within 0.3–0.4 m. The thickness of the metal from different manufacturers may vary. On average, it is 0.4–0.5 mm.
You should also pay attention to the design. This profile is distinguished by a profiled plate, which provides it with increased strength and rigidity compared to the side parts. The element is used as an auxiliary. It is needed in order to fix the CD.
As for the latter, it is on him that the main load from the drywall construction falls. One sheet is fixed with at least 4 such profiles. The width is 60 mm, the height is 25 mm. Length varies between 30-40 cm.
Metal suspensions are required for mounting the profile. They are attached directly to the ceiling.
For the installation of multi-level structures, profiles with a different marking are used - CW and UW. As in the process described above, the first one performs the function of the main one, the second - the auxiliary one. They also applyfor mounting ceilings with decorative curved inserts.
It is also important to choose self-tapping screws. Depending on the specific project, they can be used for installation with a length of 70–100 mm. Also choose dowels with a diameter of 6 mm. Sometimes additional fastening material may be needed. The issue with him is also being decided at the design stage.
If in doubt about which drywall is best for the ceiling, it is recommended that you first consult with a specialist to avoid additional costs.
