Among the advantages of GCR is to highlight:

• increased flexibility;
• high strength;
• small thickness;
• high thermal insulation and noise insulation;

• lack of foreign odors;
• ability to regulate indoor humidity.

The disadvantages of arched drywall include:

• inconvenience during work;
• cutting complexity;
• the complexity of screwing fasteners;

Excessive thinness of the sheet increases the amount of material used, and it is financially expensive. The thickness of the commonly encountered arch drywall is 6 mm and 6.6 mm, the length and width depends on the manufacturer, the most common dimensions are 1.2 x 2.5 m, 1.2 x 3 m.

In order to properly make an interior doorway of drywall with your own hands, you must first prepare the necessary tools and follow strict rules when performing.

Initially you need to prepare:

2. installation of a doorway.

To carry out the work correctly, you can take note of the step-by-step instructions for mounting the frame:

• Rack doorway fastened to the ceiling and the floor (to the profiles).

• The connection is made with screws.
• If necessary, additional rigidity, you can insert a wooden bar in the doorway.

Upon completion proceed to the second stage. This is laying drywall, which is performed in compliance with the basic rules:

• The distance from the screw to the edge of the sheet of drywall should be equal to 1 cm.
• The distance between fasteners should not exceed 15 cm.
• GKL, located next to, must be on the same profile.
• The fastening cap is driven into the sheet to a depth of no more than 0.8 mm.
• The suitable size of the screws is 2 cm.

Then perform all the work on sealing joints and cosmetic procedures. So fixed sheets of drywall on the prepared frame look beautiful and aesthetically pleasing, forming an opening.

In order not to spoil the repair, exclude additional expenses for finishing and construction materials, need to consider some of the nuances:

• Drywall does not like moisture, from its excess it can fall apart.
• Complete drying of the finishing material takes at least 12 hours.
• To avoid rust spots on the surface over time, it is better to use galvanized screws or stainless steel fasteners for fastening.
• In order not to get enough sleep plaster, it is necessary to screw the screws to a clearly specified depth.

Choose and apply finishing material must be strictly for the purpose. For example, for a multi-level ceiling and curved structures, an arched material is used, which can be given any shape, and for walls more dense wall material with a number of additional advantages is suitable. Sheets must be used within a few days of purchase.
