What is the ceiling hollowing rate

The calculation formula of the hollow rate of the ceiling = the area of the hollow part of the ceiling The area of the overall ceiling 100% of the ceiling decoration materials distinguish the main basis for the name of the ceiling, mainly: light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long aluminum gusset ceiling, square painted aluminum gusset ceiling, stained glass ceiling, aluminum honeycomb perforated sound-absorbing panel ceiling, whole house duplex ceiling, etc.

It occupies a very important position in the decoration of the whole room, and the appropriate decoration of the top surface of the room can not only beautify the indoor environment, but also create a colorful artistic image of the indoor space.

When choosing ceiling decoration materials and design schemes, it is necessary to follow the principles of material saving, firmness, safety, beauty and practicality.

The calculation formula of the hollow rate of the ceiling is the area of the hollow part of the ceiling and the area of the overall ceiling) 100%.

The construction of the ceiling includes steps such as laying the keel, applying gypsum board, dealing with nail holes, caulking, and applying bandages. The ceiling in the living room takes about 5-7 days, and it also needs to do waterproof work, so it is much longer in the construction period.

1. Before the formal construction, the workers should first use the horizontal pipe to measure whether the ink line of the wall elastic is horizontal, and only to ensure the true level of the base line will not make the ceiling installed later inclined or there is a height difference.

2. The gypsum board ceiling needs to be fixed on a firm wooden keel frame, so the careful selection of the keel material has become an indispensable step.

After nailing the keel frame, it is necessary to fix the frame on the wall, and then carefully check whether the spacing between the frames is not more than 300mm to have sufficient fastness (also according to the distance between the lights, downlights, and spotlights installed on site, otherwise there will be some small troubles in the installation). Otherwise, the gypsum board on it is easy to sink and break.

After the gypsum powder fills the gap, it is best to paste it on the surface with anti-crack tape to prevent the top surface from cracking caused by thermal expansion and cold contraction. When pasting, pay attention to remove air bubbles with a scraper while pasting, so that the tape and gypsum board are thoroughly and tightly combined.

The calculation formula of the hollow rate of the ceiling is the area of the hollow part of the ceiling and the area of the overall ceiling) 100%.

Hollow ceiling panels:

Suspended ceiling (English name: sprung roof) refers to the top decoration of the living environment of the house. To put it simply, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration.

The ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption, and is also a hidden layer for electrical, ventilation and air conditioning, communication and fire prevention, alarm pipeline equipment and other projects.

It is the ratio of the unsuspended area of the top surface to the total area of the top surface after the ceiling.
