What kind of material lines are usually used for indoor ceiling?

The types and selection of ceiling materials

The ceiling is the third main interface of the interior space, it has two forms: one is in the floor and roof of the bottom, with a variety of different materials directly and structural framework connection, or hanging on the structural framework that is to do the ceiling; the other is to let the structure is exposed as the ceiling.

Suspended ceiling is often used in interior design, is the largest unoccupied area in the room, people's eyes tend to contact with it more time, so the shape of the ceiling and texture of the art of dealing with the effect of the space is very obviously affected. Ceiling materials are mainly mineral wool board, paper-faced gypsum board, wood panels, plastic, glass, metal and several other.

Timber is the most commonly used materials in the ceiling, with the advantages of sound insulation and heat preservation; paper gypsum board for the ceiling, the surface of the material can be brushed with paint or stickers on the top of the paper, construction is convenient, high strength, good processing performance; glass ceiling is a combination of lighting fixtures **** with the combination of the ceiling form, with painted glass can add more artistic effect. The above types are mostly used in the hall. PVC plastic buckles, plexiglass, frosted glass, mineral wool boards are commonly used in the kitchen, bathroom ceiling, their shortcomings are easy to aging, not easy to clean or single color, poor decorative. The metal ceiling gradually become the new favorite of the ceiling of the cabinet and bathroom. Compared with traditional materials, metal ceiling has some of the following characteristics: color and lustre elegant and diverse, three-dimensional sense of strong, good decorative effect; fire prevention, waterproof performance is good; light material, high strength, easy to install; has a good sound-absorbing, acoustic effect; smoke cleaning is convenient; long service life, not easy to deformation and discoloration.

In the home decoration of the ceiling keel materials are mainly wood keel, aluminum alloy keel, light steel keel and so on. The traditional ceiling keel for wooden materials, the panel part of the artificial board. Light steel keel is a new material, it is galvanized steel, cold bending or stamping and become the roof and skeleton support materials. It is characterized by light weight, high rigidity, good fire and seismic performance, easy processing and installation.

PVC board and aluminum ceiling material comparison

PVC board

PVC board with PVC as raw material, waterproof, moisture-proof, moth-proof. Containing flame-retardant raw materials, it is safe to use.Most of the PVC boards are mainly in plain color, but there are also imitation pattern and imitation marble pattern. Its cross-section for the honeycomb mesh structure, both sides of the molding of the mouth and concave tongue and groove, which is the details of the selection, the requirements of the mouth and concave tongue and groove complete and straight, each other bite smooth, local no undulation and height difference phenomenon. pvc board per square meter ranging from 12 to more than 20 yuan, it can be said that good value for money. But because of the poor performance of high temperature resistance, used in kitchens, bathrooms and other hot environments are prone to deformation.

Aluminum panel

Aluminum panel can be fire, moisture, anti-static, sound absorption, sound insulation, and beautiful and practical. But the price is as high as 200 yuan / square meter, the domestic one is also 50-60 yuan. Aluminum flower plate surface perforated and flat two kinds. Surface perforation can be ventilated sound absorption, buckled inside a layer of film cushion, moisture can be absorbed through the perforation by the film, so it is most suitable for more moisture in the kitchen and bathroom use.

What's the difference between PVC plastic buckles and aluminum alloy buckles? What should I pay attention to when I use it?

PVC plastic buckle plate water resistance, scrub resistance is very strong, compared with the lower cost, aluminum alloy buckle plate texture, decorative feel better.

PVC plastic buckled plate to PVC as raw material, light weight, easy to install, waterproof, moth-proof, the surface of the color pattern change is also very much, and pollution, good cleaning, sound insulation, heat insulation, especially the new process of adding flame-retardant materials, so that it can be extinguished from the fire that is, the use of more secure. The disadvantage is that the service life is relatively short compared with the metal material ceiling plate.

Purchase of PVC ceiling profiles, in addition to the dealer to ask for quality inspection reports and product testing certificates, you can visually inspect the appearance of the quality of the board should be flat and smooth, no cracks, no bumps, can be dismantled and installed freely, the surface has a glossy surface without scratches, with a hand knocking the board sound crisp.

Plastic buckled ceiling by 40mm × 40mm square wooden board composed of skeleton, in the skeleton below the nail plastic buckled, this ceiling is more suitable for decorating the bathroom ceiling.

PVC ceiling profiles if damage occurs to update the very convenient, as long as the end of the pressure bar removed, the board by piece from the pressure bar out of the board, with a new board to replace the damaged board, and then re-installed to press the good pressure bar. Replacement should pay attention to minimize the color difference.

Aluminum alloy buckle plate compared with traditional ceiling materials, texture and decorative sense of superior. Aluminum alloy buckle plate is divided into sound-absorbing plate and decorative plate two kinds, sound-absorbing plate hole type has round holes, square holes, long round holes, rectangular holes, triangular holes, the size of the combination of holes, etc., most of the base plate is white or aluminum color; decorative plate pay special attention to the decorative, clean and smooth lines, bronze, gold, red, blue, milky white and other colors to choose from. There are rectangular, square, etc., rectangular plate of the largest specification of 600mm × 300mm, the general width of the room is about 5 meters more than the larger room decorative selection of rectangular plate overall sense of the stronger, on the decoration of the small room can generally be selected 500mm × 500mm, due to the poor insulation properties of the metal plate, in order to obtain a certain sound-absorbing, adiabatic function, in the selection of the metal plate for the ceiling decoration. Can be used within the addition of glass wool, rock wool and other thermal insulation sound-absorbing materials to achieve the effect of adiabatic sound-absorbing.

How to choose the ceiling keel

The keel is an indispensable part of the decoration of the ceiling, including wood keel and green steel keel. The use of wood keel should pay attention to the wood must be dry. Now most of the family decoration selection is not easy to deformation, with fire performance of light steel keel, selection should pay attention to the thickness of the keel, preferably not less than 0.6 millimeters.

Ceiling metal keel is generally made of light steel and aluminum alloy, has a light weight, rigidity, fire resistance and seismic performance is good, easy to process and install and so on, according to the profile section, there are U-type keel and T-type keel. RuLong partition wall keel has the advantages of light weight, high strength, good anticorrosion, etc. It can be used as the skeleton material of light partition wall, mainly used with paper-faced gypsum board and its products, and can also be used with other boards such as: GRC board, FT board, ET board and other materials.

Additionally, when decorating, pay attention to the difference between the original plate galvanized keel that is not easy to rust and the post-galvanized keel. The original plate galvanized keel is commonly known as "snowflake plate", there is a snowflake pattern on it, and the strength is higher than the post-galvanized keel.

Additionally, it's best to use a rust-resistant galvanized keel to avoid using a post-galvanized keel. Difference between the two should be noted that the original plate galvanized keel is commonly known as "snowflake board", above the snowflake pattern, the strength is higher than after the galvanized keel

Ceiling decoration materials

1 gypsum board ceiling

Gypsum ceiling is a cooked gypsum as the main case of raw materials mixed with additives and fibers made of lightweight, insulation, sound-absorbing, sound-retardant and light-weight, with the ability to absorb heat and moisture, and to prevent the formation of dust. It has the properties of light weight, heat insulation, sound absorption, flame retardant and sawing. Mostly used with commercial space science, generally 600600 specifications, there are open bone and dark bone points, keel commonly used aluminum or iron.

3 Plywood ceiling

Plywood (also called plywood) has the advantages of lightweight material, high strength, good elasticity and toughness, resistance to shock and vibration, easy to process and finish, insulation and so on. It can also easily create a variety of curved, round, square and other molding ceiling, but the disadvantage is afraid of termites.

4 Alien strip aluminum ceiling

Now, most of the home improvement has been no longer use this material, mainly because it is not dirty and easy to deformation.

5 Square painted aluminum ceiling

In the kitchen, toilet and other places that are easy to dirty, is the mainstream product.

6 Painted glass ceiling

This ceiling has a variety of graphic patterns, the interior can be installed lighting devices, but generally only used with local decoration. Decoration if you use light steel keel plasterboard ceiling or plywood ceiling, in its face paint, plaster powder should be used to seal the joints, and then sealed with kraft tape paper before priming and painting.

No matter what material is used to decorate the ceiling, one thing should be remembered: sealing! To prevent mice and cockroaches from making nests within it.

How to choose and buy ceiling materials

Ceiling is a technique often used in interior design, people's eyes tend to contact with it more time, so the shape of the ceiling and the artistic treatment is very obviously affect the spatial effect.

Environmental indicators of suspended ceilings

According to national environmental protection standards, the level of radioactivity of ceiling materials is divided into three categories: (mainly applicable to non-metallic, non-organic ceiling materials, such as gypsum boards, etc.)

1, class A decorative materials decorative materials in the natural radionuclides radium-226, thorium-232, potassium-40 specific activity of radioactivity at the same time to meet the requirements of 1Ra ≤ 1.0, 1r ≤ 1.3 for the class A decorative materials. class A decorative materials production, marketing and use of the scope of unrestricted.

2, class B decorative materials do not meet the requirements of class A decorative materials, but at the same time to meet the requirements of 1Ra ≤ 1.3, 1r ≤ 1.9 requirements for class B decoration materials. B decoration materials can not be used for class 1 development of the building of the interior finish, but can be used as a class of civil buildings, and the exterior finish and all other buildings of the interior and exterior finish.

3, C decorative materials do not meet the requirements of A, B decorative materials, but to meet the requirements of 1r ≤ 2.8 for C decorative materials. C decorative materials can only be used for the building's exterior finish and outdoor use.

Note: Class I civil buildings: such as residential, senior citizen apartments, child care centers, hospitals and schools.　　

II civil buildings: such as shopping malls, stadiums, bookstores, hotels, office buildings, libraries, cultural and entertainment venues, exhibition halls and public **** traffic waiting room.

Classification, purchase, installation, maintenance of suspended ceilings

The ceiling materials are mainly mineral wool board, gypsum board, wood panels, PVC plastic fasteners, glass, metal and so on.

1, PVC plastic fastening board

①Features

It is made of PVC, processed into a pengkou type profiles, light weight, easy installation, waterproof and moisture-proof, moth-proof features, it is the surface of the color pattern change is also very much, and pollution resistance, good cleaning, sound insulation, heat insulation, good performance, especially in the new process of adding a flame-retardant materials to make the fire can be extinguished. It can be extinguished by fire, and is safer to use. It has low cost and good decorative effect, therefore, it occupies an important position in the ceiling material of home decoration, and becomes the leading material of the ceiling of bathroom, kitchen, washroom, balcony and so on.

② quality identification

Purchase PVC ceiling profiles, be sure to ask the dealer for quality inspection reports and product testing certificates. Visual inspection of the appearance of the quality of the board should be flat and smooth, no cracks, no bumps, can be installed and removed freely, the surface of the raging no scratches; knocking the board by hand sound crisp. Check the test report, the product's performance indicators should be met: thermal contraction rate of less than 0.3%, oxygen index is greater than 35%, softening temperature of degrees Celsius or more, ignition point of 3000 degrees Celsius or more, water absorption rate of less than 15%, moisture absorption rate of less than 4%.

③Installation

First of all, the elevation line should be popped up on the wall, and the pressure line should be fixed on both ends of the wall, and the cement nail should be fixed firmly with the wall. Sheet according to the actual size of the ceiling cut, insert the sheet into the pressure strip, the slats of the mouth to the outside, after the installation of the correct, fixed with nails, and then insert the second board ...... last board should be cut according to the actual size of the cut using a sharp knife, with a steel ruler pressed against the spring line cut, loaded with a little bending can be inserted into the last board in the mouth, and then the board can be inserted in the last board, and the last board should be cut according to the actual size of the cut. After loading the two sides of the pressure strip seal.

④Maintenance and replacement

PVC ceiling profiles of water resistance, scrub resistance is very strong. In daily use, it can be scrubbed with cleaning agent and then washed with water; the board is easy to be oiled between the seams, so it can be cleaned with a brush dipped in cleaning agent and then washed with water; pay attention to the lighting circuits and don't dip in water; it's very convenient to update the PVC ceiling profiles if they are damaged, as long as you remove the pressure bar at one end, pull the boards out from the pressure bar one by one, and then replace the broken boards with the new boards and then reinstall them, and then press the pressure bar well. Replacement should pay attention to the new board and the old board color needs to be the same, do not have a color difference.

2, metal products ceiling

Metal products ceiling refers to a set of multi-functional, decorative in one of the ceiling metal decorative panels. Compared with the traditional ceiling materials, in addition to maintaining its characteristics, texture, decorative sense of better, can be divided into sound-absorbing plate and decorative plate (not open hole). Acoustic plate is based on acoustic principles, the use of a variety of different perforation rate of the metal plate to achieve the elimination of noise, but also according to the need for round holes, square holes, oblong holes, rectangular holes, triangular holes, the size of the combination of holes, such as different types of holes, most of the base plate is white or aluminum color. Another metal decorative plate, pay special attention to decorative, clean and smooth lines, beautiful shape, elegant color, bronze, gold, red and blue, milky white and other colors; specifications coincide with the width of the ordinary residential coincide with the whole, and marble, aluminum alloy doors and windows and other materials connected to a seamless integration of elegance and magnificence, for the appropriate quiet living room environment to add to the flowers.

Metal decorative plate material types are aluminum, copper, stainless steel, aluminum alloy, etc., choose copper, stainless steel material decorative plate grade is higher, the price is also high, the general room decoration, choose aluminum alloy decorative plate is more appropriate, in line with people's general shopping mentality, that is, inexpensive. Specifications have rectangular, square, etc., the maximum specification of rectangular plate 6000mm * 100mm * 0.5mm, the general width of the room is about 5m more than the larger room decoration, the choice of rectangular panels of strong integrity; the decoration of the small room can generally choose 500mm * 500mm. Due to the poor insulation properties of the metal plate, in order to obtain a certain sound-absorbing, adiabatic function, in the choice of metal plate for ceiling decoration, you can use the internal addition of glass wool, rock wool and other thermal insulation products to achieve the adiabatic sound-absorbing function. Especially the residents living in the top floor, after decoration can improve the indoor environment, obviously save the air conditioning energy consumption costs.

3, gypsum board ceiling

Gypsum board is a new type of widely used ceiling decorative materials, has a good decorative effect and good sound-absorbing properties, the more commonly used cast gypsum decorative panels and paper decorative sound-absorbing panels.

Pouring gypsum decorative board has a light weight, moisture, no deformation, fire, fire retardant and other characteristics. It has the advantages of convenient construction, good processing performance, sawing, nailing, planing and bonding. The main varieties are: all kinds of flat boards, patterned relief boards, semi-perforated boards, fully perforated boards, waterproof boards and so on. Patterned relief board is suitable for living room, bedroom, study ceiling; waterproof board is mostly used in the kitchen, bathroom and other places with high humidity.

Paper decorative acoustic panels are characterized by fireproofing, sound insulation, heat insulation, good anti-vibration performance and easy construction.

Ceiling uneven causes and prevention

1, the phenomenon: the ceiling appeared irregular waviness

2, the cause of the analysis:

①Arbitrary arching, the formation of uneven arch.

② ceiling perimeter grille or uneven corners.

3 wood moisture content is large, resulting in shrinkage and deformation.

④The keel joints are uneven with hard bends, resulting in uneven ceiling.

⑤The spacing between the boom or the hanging bar is too big, and the keel deforms to produce irregular deflection.

6 stress node combination is not strict, after the force to produce displacement deformation.

3, preventive measures

①The ceiling wood should be used high-quality soft wood, such as pine, cedar, its moisture content should be controlled within 12%.

② keel should be straight, should not be twisted and have a transverse section through the knots.

③ ceiling should be designed according to the height of the wall around the line leveling, nailing around the horizontal line shall prevail, rubbing the horizontal line of the arch height of the room short span 1/200, longitudinal arch should be hanging evenly.
