You don’t know if you don’t see it! Decorate the \”door\”! ! To be so particular

Doors and windows are the \”animity and light and shadow\” of the home. Just looking at the content of \”window decoration\” cannot constitute \” \”Door and window decoration\”, so I decided to continue talking about \”door\” decoration with everyone, and try to explain clearly your questions and common pitfalls when buying doors, let\’s talk! bright! white!

（ The picture comes from the Internet and has been deleted)

Not much to say! Today we will first understand the basic content of door decoration, so that everyone can have a preliminary understanding of door decoration.

Door structure

Doors are indoor and outdoor transportation hubs, which serves to separate spaces(also plays the role of ventilation and lighting). Next, I will take a wooden door as an example to briefly explain the structure of the door.

Our common doors generally consist of door frames, door covers, door locks, door leaves and hinges:

(The picture comes from the Internet and has been deleted)

Door frame:It is composed of two vertical It is composed of a border and an upper frame. If there are multiple doors, there is also a central mullion. The door frame is the connecting component of the door leaf, beam and wall.

Door cover: is an extension of the door frame. Its main purpose is to fix the door leaf and protect the wall to ensure that the door is not damaged by scratches, corrosion, dirt, etc.

Door lock: It is the decisive factor in determining the door\’s safety function. In terms of materials, there are space aluminum, brushed stainless steel, etc. You can choose according to your own needs.

Door leaf: It is the shape of the door(shape, color, style, feel, design). Most owners are most concerned about this part, such as the thickness of the door leaf, the material of the door leaf (solid wood, solid wood composite, paint-free , molded doors, etc.).

Hinges: It is the hardware that connects the door frame and door frame. This hinge is very important and has a long life. Generally, the hinges of indoor doors are broken, but the door leaf and door frame are still intact, resulting in the door not being able to be used normally. In this case, the hinges can be replaced.

When we talk about what kind of door to buy, we mainly distinguish it from three aspects: first, the material of the door leaf, second, the classification of door locks, and third, It is a functional classification. Let’s first analyze the door leaf material.

(A mini program has been added here, please go to Toutiao client to view)

Door leaf material

Common interior door leaf materials are generally wooden doors. Exterior doors are mostly made of iron doors, steel doors or stainless steel, aluminum alloy doors, etc. Since there are many interior doors, the following mainly analyzes the door leaf material of wooden doors.

1. Paint-free door

As the name suggests, paint-free door does not require Painted doors, most of the paint-free doors currently on the market refer to PVC veneer doors, which are made of PVC veneer vacuum plastic processing on the outermost surface of solid wood composite doors or molded doors.

In terms of price, paint-free doors are the cheapest, but cheap does not mean cheap! People think that paint-free doors are cheap and cannot offer high quality, but in fact, they also have many well-known brand doors. There are brands of paint-free doors with varying prices.

It should be noted that paint-free doors are easily affected by humidity, temperature and air factors, which may cause surface damage. The glue will deform and the sound insulation effect will be weak.

2. Solid wood composite door

Solid wood composite door is the most common choice for most homeowners’ homes. It is mostly made of pine, fir or imported filler, and then density board is pasted on the outside of the door core. The outermost layer is covered with solid wood veneer, and then undergoes special processing to finally become the finished door.

It can be seen from the materials of solid wood composite doors that solid wood composite doors are generally lighter. And because there is only a layer of solid wood veneer on the surface and not solid wood on the back, the finished door is less likely to deform and crack. Not only that, solid wood composite doors have better thermal insulation, impact resistance and flame retardancy, and even the sound insulation effect is almost the same as that of solid wood doors.

3. Solid wood door

Solid wood door is made of natural logs as the door core, which has been dried and planed , high-speed milling and other processes are scientifically processed. The finished door after processing has the characteristics of no deformation, corrosion resistance, no cracks, good sound insulation effect and heat insulation. However, it uses pure solid wood processing. If the solid wood is not dehydrated properly, the door body will be easily deformed and cracked after being made into a wooden door, and its flame retardancy will be relatively poor.

（ Picture fromInternet, intrusion and deletion)

So in fact, solid wood doors are not recommended. The cost of this kind of door is high, and compared with solid wood composite doors, the appearance is also poor. There are no obvious advantages, and the price/performance ratio is not high. If it is not a luxury house, it is really unnecessary!

4. Molded doors

Molded doors are generally made of wood from artificial forests, peeled and sliced , screened and ground into dry fibers, mixed with phenolic glue as a binder and paraffin, and then molded at one time under high temperature and pressure. It is actually a high-density fiberboard with a concave and convex pattern.

Because it is made of non-solid wood materials pressed on a hot press, the surface pattern is not a solid wood material, but a It is machine formed, so its cost is lower. However, due to limited molds, there are not many styles, only fixed styles, and beautiful patterns with smooth lines cannot be made.

And most molded doors are very light. The sound insulation effect is not as good as that of solid wood doors, and it cannot be wetted or bumped. It has poor environmental performance, so if it is only used for decoration and does not pay attention to practicality, you can choose it. Otherwise, it is not recommended.

Summary:

Among all the above door leaf materials, the comprehensive properties of solid wood composite doors are the best. It is recommended to use it first;

In terms of sound insulation and heat insulation effects, the relationship between several doors is Solid wood door>Solid wood composite door>Paint-free door>Molded door;(The same is true for the price comparison relationship)

In terms of decorative effect, molded doors are more cost-effective, and solid wood doors are high-end and elegant.

Classification of door locks

There are many types of door locks, and they can be found from different angles There are many divisions. Currently, there are two main types of door locks on the market: mechanical locks and smart locks. Mechanical locks can be used for indoor or entry doors.Selection, while smart locks are mostly used for entry doors.

1. Mechanical lock

At present, the main materials for making mechanical locks include stainless steel, copper, zinc alloy and Aluminum alloy, different materials have their own advantages and disadvantages, let me give you a brief analysis:

①Angle of selection:

From durability From the perspective of selection, stainless steel mechanical lock is the best choice;

From a safety perspective, aluminum alloy and copper door locks are more suitable choices;

If If you have high requirements for the lock\’s shape, you can choose a pure copper door lock, which is more magnificent.

②Selection grade:

The grade of the lock cylinder is related to the safety factor of the door lock. Generally divided into three levels: A, B, C(Super B).

(The picture comes from the Internet and has been deleted)

A-level lock cylinder: Mainly equipped with one With word keys and cross keys, thieves can open them in more than ten seconds, so their safety factor is very low.

B-level lock cylinder: Mainly include computer double-row lock cylinder, double-row crescent lock cylinder, double-sided blade lock cylinder, equipped with The flat key has a double row of pin slots. The key surface has an extra row of curved and irregular lines than the A-grade lock cylinder, which has a higher safety factor.

C-level lock cylinder: It adopts double row, computer, compound curve groove patented key, which is mostly used in the financial industry and has the highest safety factor.

（ The picture comes from the Internet and has been deleted)

After comprehensive consideration, it is recommended that you try to choose the C-level with the highest safety factor when choosing a lock cylinder, followed by It\’s Class B.

2. Smart lock

Smart lock unlocking methods mainly include fingerprint locks, IC card unlocking, face recognition, and password locks, each with their own characteristics. Let’s find out together.

①Fingerprint lock

Fingerprint lock, simply put, is a lock that is opened by human fingerprint. Currently, there are two main recognition modes for fingerprint locks on the market: photoelectric fingerprint recognition and semiconductor fingerprint recognition.

(The picture comes from the Internet and has been deleted)

Compared with the two, the photoelectric fingerprint lock can recognize the fingerprint image, and The semiconductor fingerprint lock can only identify living fingerprints and has finger vein flow detection, which is more secure and more difficult to copy.

②Face recognition unlocking

（ The picture comes from the Internet and has been deleted)

Face recognitionDon\’t open the door is mainly divided into two types: 2D face recognition and 3D face recognition. Relatively speaking, the 2D face recognition door opening technology is not yet mature, and it may recognize the selfies you post in your circle of friends. It is not safe and is not recommended for everyone.

③Password lock

（ The picture comes from the Internet and has been deleted)

Password lock refers to key password unlocking. You don\’t need to bring a key, which is more convenient, but it requires people to remember the password, and the durability and security are low.

④IC card unlocking

（ The picture comes from the Internet and has been deleted)

IC Card Unlocking SimpleThe simple understanding is to swipe a card to unlock the door. Currently, there are two main types of IC cards, one is MI card and the other is CPU card. MI cards are easy to be copied and remade, and are software-encrypted, with low security; CPU cards are difficult to copy, and are hardware-encrypted, with much higher security.

Look at the picture below to understand the unlocking method of the smart lock more intuitively:

Door function type

Slave door function The types are classified. Common ones include security doors, fire doors, silent doors, invisible doors, barn doors, etc. Let’s take a look at them below.

1. Anti-theft door

The full name of anti-theft door is \”anti-theft safety door\”, which is the most common anti-theft door on the market. Most of the materials are made of steel, but there are also anti-theft doors made of other materials, which are generally divided into five types: steel, stainless steel, copper, steel-wood structure and aluminum alloy.

（ The picture comes from the Internet and has been deleted)

According to the different material characteristics of security doors, in In the national standard GB17565-2007 \”General Technical Conditions for Anti-theft Security Doors\”, anti-theft doors are divided into four levels: A, B, C and D according to the time to prevent external damage. From A to D, the safety performance Gradually reduce. (Anti-external damage time means that no matter what form of abnormal opening method is used by the outside world, the anti-theft door cannot be opened within these XX minutes, nor can it be opened by destroying the steel door body Security door)

（ The picture comes from the Internet and has been deleted)

But in fact, the key to anti-theft is not the material of the door, but the lock core, which is the upperAmong the lock cylinder grades we mentioned, grade C has the best safety factor, followed by grade B. (Thieves don’t care about the quality of your door! They only care about the lock. Because lock picking is silent , and it’s very fast, it can be done in just a few dozen seconds)

2. Fire doors

Fire doors refer to Doors that meet fire resistance stability, integrity and thermal insulation requirements. It is a fire-resistant partition with certain fire resistance located in fire-resistant partitions, evacuation stairwells, vertical shafts, etc.

(The picture comes from the Internet and has been deleted)

In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire. With the function of smoke diffusion, it can prevent the spread of fire within a certain period of time and ensure the evacuation of people. It is a very important line of defense to protect the safety of people\’s lives and property.

3. Silent door

If you want to have a refined sleep, it is best to choose a silent door for your bedroom door. A silent door is a door that uses slide rails and some noise-cancelling accessories to open and close silently. It is usually a sliding door.

(Pictures are from the Internet and have been deleted)

The principle of the silent door is to incorporate soft magnetic technology into the design and production. Then the door edges of the silent door can fit together well when closed to achieve the purpose of silence.

4. Invisible door

An invisible door is a door that does not require a door frame, a lock, or a handle on the outside. It is difficult to directly observe the shape, size, and style of the door after it is closed.

（ The picture comes from the Internet and has been deleted)

Invisible door can also be understood as hiding the door. When others see it, it gives others the illusion that it is not a door. Of course, invisible doors not only give people a clean and comfortable feeling in terms of decoration, but also have the function of visually enlarging a small space.

5. Glass door

Generally speaking, transparent glass doors are a common choice for kitchen doors. The large area of ​​glass can not only isolate oil fumes, but also display the cabinets carefully selected by the owner.

Furthermore, the kitchen is one of the most complex places in the home. Work such as washing vegetables and dishes will increase the burden of the kitchen. Depending on the humidity level, choosing a glass door not only provides good ventilation but also effectively improves the lighting in the kitchen.

Not only for kitchens, glass doors are also a common choice for balcony doors, with good light transmittance and a wide variety of glass , there are many colors, the decorative effect is good, it is easy to match with many popular styles now, and there is a lot of room for price selection.

6. Barn door

The barn door is a wooden sliding door originating from foreign farms, with exposed slide rails and an original and simple shape. With continuous development, barn doors can be made simple and elegant, or fresh and natural, and storage space can even be added to the barn door in various forms.

Barn doors have poor sealing and sound insulation effects, and generally do not install door locks or only install traditional door locks. Therefore, it is not recommended to use it in spaces with strong privacy (such as bedrooms, bathrooms, etc.).
