When decorating, many people think that interior doors do not require too much investment, so they do not do much homework when purchasing. In fact, only after moving in will you know that the importance of interior doors cannot be ignored.

As someone who has renovated a house twice, let me tell you about the tasteless experience caused by incorrect indoor door selection:

① strong smell ( formaldehyde content is high);

② door locks are easily damaged (short service life);

③ stains are difficult to remove (not resistant to dirt).

Although indoor doors are a building material that does not account for a large proportion of the budget of the entire decoration project, it is directly related to the experience of our home life , so naturally it cannot be cheap.

However, the quality of indoor doors on the market, whether it is the building materials market or the e-commerce platform, is uneven, and the price is also highly variable. In addition, various terms (paint-free, baking paint, bridge hole mechanical board , solid wood composite...) make the owners confused, so it is inevitable that they will step into the trap. In this home life topic of

, I will share with you the purchase guide of interior doors. I hope it can bring you some reference.

1. How to distinguish the interior doors on the market?

Regarding the division of interior doors, there is no clear standard. Businessmen and owners basically make their own decisions. However, they can be roughly distinguished according to the following attributes.

. Divide according to "base material"

Different base materials represent different functions and characteristics of indoor doors. They can basically be divided into these types:

① Original wooden door (can also be called "pure solid wood door")

As shown in the figure below, they are all original wooden doors. The characteristic of the original wooden door is that it is made of the same kind of wood. Because it is natural wood, the natural texture is beautiful and it is the most environmentally friendly. But at the same time, the shortcomings are also obvious, such as heavy weight and expensive price (the doors carved from scarce logs are even more works of art) .

② Solid wood composite door

Solid wood composite door is currently the most common indoor door with the largest proportion on the market. It can be said that 9 out of 10 families will choose solid wood composite doors.

is nothing but solid wood composite door. Due to the difference of "core material" , there are many subdivided categories (as shown in the picture below) :

In addition to the several "door cores" I marked in the picture above, there is also a composite door with " honeycomb cardboard " added.

Since each type of solid wood composite door has different core materials and even different skins, the prices vary greatly. Many people buy solid wood composite doors, some cost a few hundred yuan a door, and some cost a few thousand yuan a door. In the final analysis, the main reason is that the filling of the door core is different.

③ Aluminum-magnesium alloy doors, glass doors, PVC folding doors, steel-wood doors , etc.

In addition to wood as the base material, adds doors made of aluminum, steel, glass and PVC, which can be classified into other categories. The characteristics of these doors are relatively clear. For example, aluminum-magnesium alloy doors are exclusive to "bathrooms". The glass door is suitable for bathroom (Changhong glass) and kitchen.

. Divide according to "process"

I believe that many people often hear terms such as " paint-free door " and "painted door" when purchasing interior doors. To put it bluntly, this is a distinction based on "craft".

According to the construction technology of indoor doors, let’s briefly introduce the science (whether it is paint-free or baked, it is actually based on the "solid wood composite door") :

① Paint-free door

Paint-free door, in short, is an indoor door that does not need to be painted. Although it is not painted, in order to ensure the smoothness, texture and anti-oil properties of the surface, the surface of the door is generally covered with a layer of PVC plastic film or melamine veneer.

Although the texture of the paint-free door is not natural enough, it is resistant to discoloration and has no color difference. More importantly, it is relatively cheap. So it is suitable for most families with basic needs.

② Paint door

Paint door, also called paint door, this kind of indoor door is sprayed with paint on the base material of the door panel. The door is then made to look more textured and refined through processes such as polishing, heating and drying. Because they are painted, many painted doors on the market are colorful and full of high-end feel. Of course, its price is generally more expensive than paint-free doors.

Please note that in the process of painting doors, it is best to consider "water-based paint". Water-based paint simply uses water as a diluent and does not contain organic solvents, so it is relatively more environmentally friendly.

2. After installing a house twice, I finally know the difference between an interior door costing 1,000 yuan and an interior door costing 3,000 yuan.

As briefly mentioned above, the prices of interior doors vary. The main reason is that the "base material" is different. In fact, in addition to the base material, there are three factors that will affect the price of a door, namely "filling structure" , "door cover material" , and "hardware quality" .

Next, as someone who has purchased interior doors twice, based on my purchase experience and homework, I will share with you the difference between interior doors costing 1,000 yuan and interior doors costing 3,000 yuan.

Let me talk about it first, because "solid wood composite doors" account for more than 90% of the market sales and are the first choice for most families, so the differences I mentioned are also based on composite doors.

. Different filling structures

Theoretically, the filling structure is the most important indicator of the price of solid wood composite doors. The solid wood composite doors currently on the market have many filling structures:

① Wooden square filling

Wooden square filling is divided into "solid wood square filling" and "spaced wood square filling". Because this filling method uses less glue, it is more environmentally friendly, but it is also heavier. Of course, the price of this kind of interior door is also relatively high.

② Bridge opening mechanical board filling

It is undeniable that most indoor doors worth about one thousand yuan on the market are filled with "bridge opening mechanical board". This tubular structure made of solid wood chips is very popular because of its sound insulation and light weight. (price is generally less than 2,000 yuan).

③ Density board filled

Density board is probably familiar to everyone. This kind of board is made of wood chips "full of glue and pressed". Its biggest characteristics are high hardness and high formaldehyde content. Therefore, the price of this kind of indoor door is generally relatively low, basically a few hundred yuan per door.

④Honeycomb cardboard is filled with

honeycomb cardboard. Although it doesn’t sound good, it is indeed a filler allowed by the country. After all, this material is relatively environmentally friendly. It is also light weight, cheap and soundproof. It is a new type of sandwich structure environmentally friendly and energy-saving material. However, its shortcomings are also obvious, such as poor load-bearing capacity and short service life.

To summarize, from the perspective of filling structure, you can refer to:

wood square filling > bridge hole mechanical board filling > honeycomb cardboard filling > density board filling .

. Door pockets are made of different materials.

Door pockets are part of the interior door, and there are also many considerations when purchasing them. If there is a difference in the price of a door, in addition to the base material and filling structure, there are also door frames and hardware. Let’s talk about door covers first.

Door cover materials are mainly divided into two types:

① Wooden door cover

② Stone door cover

In terms of price, stone door cover > wooden door cover. This is because the decorative nature of stone is relatively high, and the process requirements are also high, so the cost is high.

Wooden door covers have disadvantages such as moisture and deformation that are difficult to change, so the price is lower than stone door covers.

Of course, wooden door covers can also be invested. However, when purchasing wooden door covers, it is recommended to follow this order: solid wood door cover > multi-layer door cover > density board door cover .

. Different hardware quality

At the beginning, I mentioned that inferior hardware not only affects the experience but also has a high damage rate. As the "heart" of interior doors, hardware is important and cannot be ignored.

Taking the first set of interior doors in my home as an example, the brand and quality of the hardware were not considered, which resulted in a very poor experience after moving in. It is recommended that when purchasing interior doors, you must pay attention to the quality of the hardware. It is best to choose the first echelon of , such as Blum, Hettich , Dinggu, Higold, Dongtai and other .

Of course, if you don’t have high requirements for the brand, you can make a distinction in the material of the hardware. For example, the material of the door lock is recommended to be aluminum alloy, the material of the hinge is recommended to be
