About the types of interior doors (and the differences between them). Which modern door filler is best to choose? Interior doors with honeycomb filler

Thick cardboard is used with a laying method based on the honeycomb principle, which is why it got its name. Honeycomb filler comes in different qualities; fine mesh honeycomb and coarse mesh honeycomb.

Sometimes it’s just crumpled cardboard, which is used to fill the voids by unscrupulous manufacturers in order to reduce the cost of their products as much as possible. Honeycomb filler good quality , especially if it is fine-mesh, it provides the door with good rigidity and low heat and sound insulation. Doors with honeycomb filling are resistant to external influences , withstand changes in humidity and temperature. Such doors are lighter than conventional ones and are more suitable as decorative element

rather than restraining.

2. Rack (bar filling).

This type of door filling refers to solid or (DU) reinforced doors. And they can also serve as entrance doors to premises (DN), external doors.

Advantages: Good resistance to mechanical damage, good sound insulation properties.

Disadvantages: high cost and significant weight of the door, inability to use in rooms with variable or constantly high humidity, good flammability. There is a full slab filling and a small-hollow slab filling (partial slab filling), also called (slat filling every other time), inside the canvas the bars are located at a distance of 5-7 cm relative to each other. When partially filled, the door has sufficient strength and becomes more a light weight

and lower cost.

But at the same time it loses its heat and sound insulation qualities.

3. Extrusion filling (Tubular chipboard).

The most progressive and most often used today is filling. There are solid and tubular chipboards. Such filling, even tubular, retains the strength, heat and sound insulation properties of bar filling. At the same time, it is devoid of their disadvantages, high cost, heavy door weight, sensitivity to humidity and flammability. The honeycomb filler in interior doors is corrugated cardboard pressed into a honeycomb shape. If you look at a cross-section of a door with such a filler, the filler will remind you of a honeycomb. As a rule, the design of a door with such a filler looks like this:)

What are honeycomb doors made of?

Let's start with the door frame. It is no different from other types of doors - several beams. As for the filler, corrugated cardboard is just that: corrugated cardboard. Doors with such filling are suitable for low-rise buildings. This is due to the fact that they can withstand weights of up to eighty kilograms.

The functions of honeycombs in doors are as follows: 1) to fill empty space; 2) give rigidity to the interior door; 3) eliminate possible deformation of the door. Honeycombs can differ in hardness. There are more tough ones, and there are less tough ones.

In Russia, the most common type of honeycomb is honeycomb with a cell size of 45 millimeters and a compressive strength of 500 grams/cm2. This is the state standard. You should also remember that the size of the cells in the doors may vary depending on the manufacturer - not everyone follows state standards. Remember the main thing - what smaller size cells, the better, the higher the density and rigidity of the honeycomb filler.

Advantages of doors with honeycomb filling

the main advantage is the price. Doors with such filling are inexpensive, but again we must not forget about the cladding. If you buy a veneer door with a honeycomb core, it will be more expensive than a PVC door with the same honeycomb core. For example, our Marco DG door in natural walnut color costs around 10 -11 thousand rubles.

environmental friendliness of the door. Unlike PVC and others synthetic materials– corrugated cardboard is environmentally friendly and safe.

resistance to changes in temperature and humidity conditions, resistance to light impacts.

a door with such a filler will be light. Within seventeen kilograms.

Disadvantages of doors with honeycomb core

The main disadvantage of honeycomb core is its soundproofing properties. If you try to estimate by five-point scale, then we would give 2-3 points.

Another disadvantage of filler is that it is used to reduce the cost of door production. Hence the relative cheapness.

Most of all interior door structures are made using honeycomb door filler. Using this innovative technology beneficial not only from an economic perspective - it is a great contribution to resource conservation, thrifty and rational use of natural resources.

In its structure, the honeycomb core consists of many adjacent cells (most often hexagonal in shape) made of glued and pressed cardboard. In cross-section, the product looks like a honeycomb. The main parameters that affect quality are:

the diameter of a circle inscribed in a hexagon (that is, the size of the cell);
type and density of cardboard used;

The strength and rigidity of the material used depends on them. By changing the thickness of the filler, the manufacturer adjusts the physical characteristics of the finished product. Today, these practical fittings are used to produce durable and lightweight structures in many industrial areas.

Its advantages and disadvantages

Honeycomb core has a number of advantages:

Environmentally friendly. The raw materials used are natural and environmentally friendly.
Relatively low cost due to low cost of raw materials, saving on logistics costs and warehousing.
The manufactured structures have high strength compression and sufficient rigidity.
Good sound and heat insulation finished products.
Simple technology manufacturing.
Light weight, provided by hollow cells.
Moisture resistance, which is ensured by the properties of cardboard.

Products using this element are durable. The main disadvantage of this practical material- It is highly flammable. When processing cardboard it is used fire impregnation— the properties of this substance make it possible to correct this deficiency of the source material.

Doors with such filling, their characteristics and features

Wooden doors, which have a honeycomb filling, are manufactured according to the principle of sandwich panels. First, a frame is made from bars. For these purposes, you can choose pine or other conifers. At the places where the hinges are attached and door handle With a lock or latch, additional wood seals are installed. A filler of appropriate thickness is attached to the frame with staples.

Fabrics are used for covering chipboard sheets and MDF. The price will be higher if you use veneer made from valuable wood as a material for lining the opening. To obtain high-quality products, the hot pressing method is used by applying temperature and pressure. The final stage is gluing the edge.

Doors with honeycomb filling are produced paneled, veneered, laminated in various color scheme. Also interesting design solution may be used to varying degrees glazing, stained glass inserts, mirror components.

Thanks to the wide variety of models and characteristics, these ceilings can be installed in any room. Environmental friendliness involves the installation of such structures even in children's and medical institutions. Properties such as lightness and strength imply long-term use. There is no need to attach reinforced door hinges, and over time it will not sag under own weight and will not change its geometry.

In terms of the degree of absorption of external noise, a door with a frame with honeycomb filling is not inferior metal door. Also, the internal cellular composition, which has the properties of retaining heat, provides insulation of the room where this practical ceiling is installed.

Given the positive characteristics and features of these interior floors, the quality-price ratio is favorable.

Many apartment owners today install external armored and steel doors. It is necessary to choose the right external door, assessing not only the thickness of the metal in the door leaf, but also the characteristics of the filler. Good performance characteristics the doors are dependent on this. They need to be carefully researched to decide which door filler is right for your family.

Why is the internal filling of the door structure necessary? The purpose of these structural elements is to thermally and noise insulate residential premises from the influence of the outside world. As a result of the use of filler materials, the degree of rigidity of the door leaf increases. The quality of the internal filler and the ability of the external door design to perform its main functions are directly dependent. To understand which filler is best to use to insulate an external door, you need to find out what their characteristics are. Which door filler is best to choose? This question is asked by all people who have to solve the problem of purchasing a metal door.

What criteria should you use to choose these materials: what door filler to buy

They must be safe for environment and family members living in this apartment.
Maximum insulation from external noise in a public corridor is necessary.
The door must reliably retain heat in the apartment.
The door leaf must be waterproof.
The door must serve for a long time during its operation.
What matters is the price that the apartment owner expects.

Each apartment owner has his own priorities when arranging his home. For some, the price does not matter, for others, silence in the house is important, and so on. But it is extremely important that living in the house is safe for all family members. Therefore, it is this criterion that must be taken into account first of all when choosing building materials to solve the problem of insulating the external entrance opening.

Mineral wool from rocks

Previously, the uses of this fibrous material were limited to the defense industry. And only now they began to use it in construction.

This innovative filler is a universal material for thermal insulation and sound absorption.
Its price is relatively low and accessible to everyone.
This substance has a fibrous composition and is made from molten rocks or blast furnace slag.
Mineral wool, which was obtained by the first method (stone wool), is a high-quality filler with excellent properties.
This insulation is resistant to influence high temperature, dampness and aggressive environment, has low shrinkage.
6. Therefore, this substance is undemanding to operating conditions and can last for more than half a century.
7. This material allows for environmentally friendly filling of the door leaf, providing reliable protection for the room.
8. The excellent quality of mineral wool's resistance to ignition is used when installing fire-resistant structures and doors.

Builders consider this superior fire-retardant filler to be one of the most... effective materials for filling door leaf structures. But all this applies to mineral wool made from rocks.

Slag wool: features

Mineral wool, which is obtained from blast furnace slag (slag wool), under unfavorable conditions of dampness, high or low temperature and various types deformations does not have the property of reliable durability.

This mineral wool has a big drawback. Over time, this substance settles. This leads to the formation of voids in the cavity of the door structure. To avoid this, manufacturers install additional frame ribs that prevent the filler from sliding down.

Typically, its scope of application is country house construction, the construction of temporary structures and structures that can be easily subjected to repairs.

Corrugated cardboard: advantages and disadvantages

This inexpensive insulation for the door, having excellent property. It absorbs noise. The special design of this filler is similar to a “honeycomb”. It is a corrugated cardboard frame inside a metal door.

This material is characterized by rigidity, horizontal and vertical resistance. Gives rigidity to corrugated cardboard corrugated paper, located between cardboard layers.
His special composition does not allow moisture to pass through.
Also, the advantages of corrugated cardboard include light weight, which does not burden the door structure, and relatively low prices.
Low price, good heat and sound insulation are the undoubted advantages of this filler.

But this insulation also has disadvantages. Since it is thick paper, high humidity has a detrimental effect on him. For this reason, the service life of such external door structures is reduced if their tightness is broken.

Foam: effective, but can be dangerous

This is a good heat-insulating material with excellent noise-absorbing properties.
Its porous structure gives the filler excellent sound-absorbing qualities, frost resistance and non-hygroscopicity.
Polystyrene foam – harmless, environmentally friendly pure material, which is durable and retains its performance qualities for a long time.
Being one of the most effective heat-insulating materials, it has a very affordable price.

But a serious drawback is its extreme flammability. It melts and burns very quickly. When burned, they release a very large amount of toxic combustion products and toxic smoke. Such parameters do not allow us to count foam plastic the best option for filling the outer door.

Foamed polyurethane

This is a material that contains many bubbles. Therefore, it is lightweight and durable. The voids in the door space are filled tightly with this filler. Modern construction market offers two types of polyurethane: elastic and rigid. The latter has the greatest application.

It is highly wear-resistant, moisture-proof, durable, environmentally friendly, and effectively protects against extraneous sounds. This is a good insulator.
Typically, this substance is used to install high-quality external doors, since it has a higher cost than mineral wool and polystyrene foam.

In addition, being a synthetic material, polyurethane filler is highly flammable and emits toxic substances. This can be an argument against such material when deciding what filler to find for doors.

Foampropylene: pros and cons

Foampropylene combines very valuable features of synthetic materials - fillers for metal doors. This material has good thermal, hydro- and sound insulation characteristics for a long time.
Its service life is designed to last up to 70 years, it is resistant to various loads.
Its advantages are low weight, ease of installation, resistance to impact chemical substances. It is pumped under pressure and does not shrink, unlike mineral wool.
The fire safety characteristics of this substance are much better than those of polyurethane filler and foam.

However, it is still a highly flammable material. And this is a serious disadvantage when choosing insulation. You need to keep this in mind when deciding which door filler to use.

It is up to the apartment owner to decide which door filler to choose. However, when buying a material, you need to meticulously evaluate its consumer properties. The insulating qualities of the door leaf are directly affected by the characteristics of the filler. When purchasing a door, you should look not only at its aesthetic qualities, but also find out what it is filled with door leaf. It is also useful to study the documents for these materials. In this case, you can make an informed choice and decide which insulation for doors to purchase.

Having made an analysis and comparison building materials, which can be used as fillers for an external metal door, we can come to the conclusion:

Comparing the thermal characteristics of expanded polystyrene and mineral wool, we can talk about their equivalence.
In terms of noise absorption, mineral wool filler is more preferable.
IN modern conditions the most preferable option for insulating external metal doors of economy class is mineral wool High Quality (stone wool). It is this filler that can provide good insulating properties to an external door. Moreover, it is the safest. It is the safety of building materials that is taken into account when deciding which filler to choose for a door.
When filling a business class external metal door, propylene foam and polyurethane foam are usually used, as they are more expensive and have good insulating qualities. But these materials are flammable.

The right choice of material for filling an external door will help make your home more cozy and comfortable.

Insulation problems are solved individually by each apartment owner.
