Doors with honeycomb filling - design features. Filling doors. Massive or cellular? According to the device, the products are

Interior doors complement the design of our home. Pleasing to the eye with its variety of laminated, veneered, painted surfaces. We do not wonder what is in the middle of the product. It's a pity, because the internal component - filling, largely determines the sound and thermal conductivity of the canvas, and also affects its strength, ability to maintain geometry and service life. There are several types of filling: honeycomb, bar, chipboard, tubular chipboard, etc.

Honeycomb filling of the door leaf

The beginning of the era of aircraft construction (40-50 years) was the appearance of honeycomb fillers. They were used to lighten and give permanent shape to aircraft structures. The composition began to be actively used for interior doors in the middle of the last century, making them stronger, lighter, and cheaper. Such filling of the internal space is one of the most common today.

Honeycomb filler is cells (honeycombs) made of pressed cardboard - corrugated cardboard, compressed by a material enclosed in a frame. With the help of bars, the place near the lock is strengthened, and due to the air spaces in the cells, the filler makes the doors lighter (max 17 kg), facilitates installation and reduces the load on the hinges. All the advantages of honeycomb filling include moisture repellency and support for a permanent shape. Such doors made of chipboard and MDF are given a presentation: they are laminated, veneered or simply painted. Modern filler (shockproof alloys, opaque materials) is used in canvases with an anodized aluminum (Al) profile - these are modern German doors made of aluminum (Al) and steel, in combination with glass.

Slab filling of the door leaf

Bar filler is partial. The bars inside the door are at a distance of 5-7 cm from each other, which facilitates the door leaf and the load on the hinges.

Solid filler, when the bars fit snugly together - high sound insulation and the ability to withstand heavy loads.

Filling the door leaf with chipboard

Chipboard filler is obtained by hot, flat pressing of wood particles, plus a binder. This method fills economy class products with low traffic.

Extrusion board - this filler is obtained by vertical pressing, wood particles are perpendicular to the board, which enhances strength. Such a filler is located between the canvases of MDF, chipboard, HDF. To give a presentation, it is covered with veneer or enamel.

Extrusion - tubular filler - is the use of plates with voids (holes in the form of tubes), as an alternative to honeycomb. These are much lighter, hence easier installation, less wear on the hinges, more economical, since little material is spent on the canvas. They are not afraid of a large passage of people, withstand a pressure of 20 kg / cm. sq., shockproof, heat and noise resistant. This material meets the highest quality requirements.

The company's website presents products from various profiles with a modern design. A sales assistant will help you make the right choice, professionals will fulfill an order that meets your desire, deliver and install it on time. The company has existed for 6 years in the construction market and has established itself as a serious partner.

Various means are used to improve the properties of building materials. Therefore, they can be used for different rooms. Often used for doors honeycomb filler. honeycomb pressed hydrocarton. In the context of the product like a honeycomb. More about it is described in the article.

Door construction

It is usually presented in the form:

  1. frame.
  2. Facings.
  3. Bar for the castle.
  4. Corrugated board filler.

Properties

The manufacture of honeycomb core is necessary to obtain doors. Combining with 2 layers, the sandwich panel will be strong and light. The panels may differ depending on the orientation of the structure. Due to the hexagonal shape, the compressive strength of the honeycomb core is greater compared to foam layers.

Polypropylene filler, unlike paper, has many advantages. These panels are resistant to water, acids, alkalis and salts, they have low thermal conductivity. Fire and UV protection is ensured by the selection of suitable cladding materials.

Purpose

Honeycomb filler is used in the following areas:

  1. Creation of interior doors. The material is valued for its excellent quality, minimal costs and excellent properties.
  2. Production of thick furniture elements. Due to the increase in the thickness of the material, the weight of the furniture panel almost does not increase, while its price is lower compared to chipboard, MDF.
  3. Production of furniture structures with curved surfaces.
  4. Creation of flat panels of furniture and doors. This does not require additional mechanical processing.

The use of Abaqus in modeling honeycomb cores can improve the properties of finished doors. They are of better quality and original.

Advantages

Honeycomb filler is made not only from pressed board, but also from hardboard. Material properties include:

  1. Ease. The design will last much longer. The door is easy to install, and the hinges do not sag under the weight of the canvas. Even after a few years, the product will be very easy to open and close.
  2. Heat and sound insulation. Insulation protects against cold and noise, which is an important quality for a living space.
  3. Strength. The filler has good resistance, so the doors can withstand loads up to 80 kg.
  4. Moisture resistance. Corrugated cardboard, used as a honeycomb filler, has a special composition that increases the moisture-proof properties.
  5. Affordable price. Honeycomb filler is much more cost-effective than other materials.
  6. Environmental friendliness. All filling components are safe and non-toxic.

The frame of the door is usually made of pine, and at the level of the lock there is a thickening for its insertion. Reinforcement of the web is performed near the fixation of the loops. Doors are divided into paneled and smooth, deaf and glazed, veneered, painted and laminated. Honeycomb came from Italy and is now recognized as one of the most common options for improving the properties of doors.

Paper honeycomb has its downsides:

  1. It is used to reduce the cost of manufacturing doors.
  2. Easily ignited.

Before buying, it is important to evaluate the advantages and disadvantages of the material. This uses aluminum honeycomb core, which is considered reliable and lightweight. With it, the door acquires similar advantages.

Frame characteristic

The frame of doors made of beams in terms of characteristics is almost the same as other types of doors. In order for the canvas to acquire an aesthetic appearance, as well as to make it reliable, the perimeter of the frame and the door handle are made of natural wood. The garter is made of cheaper wood, the qualities of which are almost the same as similar natural material.

The advantage of the door filler is density, lightness, which is provided by the cellular structure of the cardboard. Pressed cardboard is considered a natural and environmentally friendly material. Doors can be used in different rooms.

Finishing and fittings

Different materials can serve as decoration for doors with such a filler. The strapping of the opening of the canvases is carried out by MDF and chipboard sheets. This option is considered affordable. Valuable wood veneer is considered an expensive finish, which allows designers to experiment.

Doors are made with glazing, which looks very nice. Cloths are even and with a panel. Original options for country houses are created with vintage ornaments and mirror elements. This range of features is available at a cost. Interior doors due to decoration can become a work of art.

Since the design is lightweight, it does not need heavy hinges. For installation, universal components of hidden and open type are used. Handles and latches can be different, it all depends on the style and features of the doors.

Types of heaters

In hardware stores, many types of heaters from various manufacturers are sold. In addition to honeycomb filler, it is used:

  1. Expanded polystyrene.
  2. Plates based on foamed propylene.
  3. Minvata.
  4. Polyurethane foam.

Each material has its own characteristics. Mineral wool, expanded polystyrene and honeycomb filler are used in the insulation of economy class doors. And polyurethane foam and foamed propylene plates are necessary for elite doors and armored door voids.

How is insulation performed?

All work can be done independently. Before that, overhead elements must be removed from the canvas - handles, a lock, a peephole. Then, a wooden frame is fixed to the surface from the inside with self-tapping screws. Perform the procedure carefully so as not to damage the metal sheet.

The insulation is placed between the wooden beams and the frame base. It must be fixed with glue or fastening by surprise. Using 2 methods at the same time, it will turn out to fix the material qualitatively. It is cut there so that there is no gap between the frame and the insulation. All heaters can be cut with a metal ruler or a thin knife.

The procedure for laying the insulation is carried out by smearing the inner surface of the web with an adhesive. Apply glue in a thin layer over the sheet or in strips. Then the material must be pressed. After drying, the presence of gaps is checked. The appeared backlashes are eliminated with mounting foam.

The airtight front door also lets the cold through. During the insulation of the web, all metal parts must be covered with heat-insulating material, due to which the tightness will increase. This is the foundation for quality work.

Thus, honeycomb core is used in the construction of many doors. With it, the design will be easy and high-quality. But each person must decide for himself whether he should buy such a canvas.

Door filling is a material that is initially involved in the formation of the skeleton of the door, its internal basis. Doors have different types of filling. Let's start with the most "airy-dandelion" hollows. They are filled with honeycomb corrugated cardboard. Another such filling is called MDF. As a rule, this applies to laminated and veneered economy class doors from a low-quality manufacturer. Filling doors plays a significant role in its operational characteristics: wear resistance and practicality. Agree, you will never set a hollow light door for yourself as an entrance to an apartment. Conversely, do not install a heavy door, for example, in the openings for the toilet and bathroom. In a house built back in the USSR, where the walls are made of plaster, 30 mm thick, the entire wall structure can collapse.

We are talking with you about filling for doors: interior, sanitary, painted, building, veneered, related to wooden doors. But the filling of high-quality metal entrance doors is usually a mineral plate. Mineral wool, polystyrene or polystyrene cannot be used there.
Plastic interior doors can be filled with polyurethane fillers. At the same time, their performance properties are increased. Such doors become insulated and suitable for the street.

Real door manufacturers will never stuff paper trash into their doors, garbage for the manufacture of "pacifiers". They use natural filling with solid wood inserts made from solid softwood. This type of filling is more practical for doors used in offices, houses and apartments.

Doors filled with lath, solid-river filling

Doors filled with a massive rail are classified as full-bodied. They have higher sound insulation and are less prone to wear resistance. Ask yourself a logical question, which interior doors would you prefer, empty cardboard or full-bodied solid ones? Most likely, many buyers will choose the second option.

Specificity for places with increased traffic recommends installing doors with a denser shield massive filling. For example, in social, medical, educational, government institutions, reinforced doors of dense filling are simply a necessity. For monolithic internal reinforcement of doors, various fillers are used. It can be solid wood and tubular chipboard. The weight of a reinforced standard door leaf is more than 30 kg. And if it is a reinforced double-leaf door block already with a box and a threshold, and even a non-standard size, then it will have to be carried by four.

The company DoorExpo, as a reliable manufacturer of doors, monitors the quality of its products. Hollow interroom doors will never be made here. All our beauties are filled with an array, even construction doors. They are all wooden, except for laminated ones. Be careful to avoid hollow doors. Their service life is short. Of course, this cannot be determined right away, because expensive doors (even Italian ones) can be irresistible in appearance, but in essence be "dummy". What can we say about economy class doors - door hollowness in this segment is very common.

Many apartment owners today install external armored and steel doors. It is necessary to choose the right external door, evaluating not only the thickness of the metal in the door leaf, but also the characteristics of the filler. The good performance of the door depends on this. They need to be carefully examined in order to decide which door filler is suitable for your family.

Sectional door elements.

Why is the internal filling of the door structure necessary? The purpose of these structural elements is the thermal and noise insulation of 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. In direct proportion are the quality of the internal filler and the ability of the design of the external door to carry out its main functions. To understand which filler is better to use for the purpose of insulating an external door, you need to find out what their characteristics are. Which door filler is better to choose? This question is asked by all people who have to solve the problem of acquiring a metal door.

What criteria should be used to choose these materials: what door filler to buy

Door section with honeycomb filling.

  1. They must be safe for the environment and family members living in this apartment.
  2. Maximum isolation from external noise in the common corridor is required.
  3. The door must reliably keep heat in the apartment.
  4. The door leaf must be waterproof.
  5. The door should serve for a long time during its operation.
  6. What matters is the price that the landlord expects.

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

Mineral wool from rocks

Characteristics of the main brands of mineral wool.

Previously, the use of this fibrous material was limited to the defense industry. And only now it began to be used in construction.

  1. Such an innovative filler is a universal material for thermal insulation and sound absorption.
  2. Its price is relatively low and accessible to everyone.
  3. This substance has a fibrous composition and is made from molten rocks or blast-furnace slag.
  4. Mineral wool, which was obtained by the first method (stone wool), is a high-quality filler with excellent properties.
  5. This insulation is resistant to high temperatures, dampness and aggressive environments, has low shrinkage.
  6. 6. Therefore, this substance is undemanding to operating conditions and can serve for more than half a century.
  7. 7. This material allows for environmentally friendly filling of the door leaf, providing reliable protection for the premises.
  8. 8. The excellent quality of mineral wool resistance to ignition is used in the installation of fire protection structures and doors.

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

Slag wool: features

Scheme of a steel door with a rubber seal.

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

This mineral wool has a big drawback. Over time, sedimentation of this substance occurs. This leads to the formation of voids in the cavity of the door structure. To avoid this, manufacturers install additional frame ribs that do not allow the filler to slide down.

Usually, the scope of its application is summer cottage construction, the construction of temporary structures and structures that can be easily subjected to repair effects.

Corrugated cardboard: advantages and disadvantages

The main characteristics of the corrugated box.

This is an inexpensive door insulation that has an 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.

  1. This material is characterized by rigidity, horizontal and vertical resistance. Rigidity to a corrugated cardboard is given by the corrugated paper located between cardboard layers.
  2. Its special composition does not allow moisture to pass through.
  3. Also, among the advantages of corrugated cardboard include low weight, which does not weigh down the door structure, and relatively low prices.
  4. Low price, good heat and noise insulation are the undoubted advantages of this filler.

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

Styrofoam: effective, but can be dangerous

Styrofoam characteristics.

  1. It is a good heat-insulating material with excellent sound-absorbing qualities.
  2. Its porous structure gives the filler excellent sound-absorbing qualities, frost resistance and non-hygroscopicity.
  3. Polyfoam is a harmless, environmentally friendly material that is durable and retains its performance for a long time.
  4. 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 burning, they release a very large amount of toxic combustion products and toxic smoke. Such parameters do not allow us to consider foam plastic as the best option for filling an external door.

Foamed polyurethane

The main layouts of dispersed fillers.

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

  1. It is distinguished by high wear resistance, moisture resistance, durability, environmental friendliness, and effectively protects against extraneous sounds. This is a good heater.
  2. Typically, such a substance is used to install high-quality external doors, since it has a higher cost than mineral wool and foam.

In addition, being a synthetic material, polyurethane filler is highly flammable and releases toxic substances. This can become an argument against such material when solving the problem of which door filler to find.

Penopropylene: pros and cons

  1. Very valuable features of synthetic materials - fillers for metal doors - were combined in polypropylene. This material has good thermal, hydro and sound insulation characteristics for a long time.
  2. Its service life is calculated up to 70 years, it is resistant to various loads.
  3. Its advantages are low weight, ease of installation, resistance to chemicals. It is pumped under pressure and does not shrink, unlike mineral wool.
  4. The fire safety characteristics of this substance are significantly better than those of polyurethane filler and foam.

The front door should protect not only from unauthorized entry, but also from extraneous sounds and cold. In hot weather, it will help keep the room cool, provided quality windows, blinds and air conditioning. But due to various operational features, buyers need to figure out which filler for the front door is better, because in a private house it is expected to be protected from freezing and drips on the canvas, and in a warm entrance you want increased sound insulation.

Requirements for fillers for entrance doors

Various materials are used as a filler, which have their own advantages, disadvantages and price, which affects the final cost of the door. The best insulators for metal entrance doors have as many of the following properties as possible:

  • Thermal insulation. The design of metal doors is prone to passing high and low temperatures due to rapid heat transfer. The dense structure of the iron crystal lattice absorbs and gives off heat well. A high-quality filler breaks this connection between the outer and inner steel sheet as much as possible, retaining air in itself.
  • Soundproofing. To block the access of extraneous sounds, the insulation must absorb them well and not allow them to be reflected from its surface, which would serve as a resonator and transmit them further into the room.
  • Moisture resistance. From the ingress of precipitation on the canvas or the formation of condensate, some types of filler can wrinkle or settle. The best materials withstand such phenomena and retain their shape.
  • Fire resistance. If vandals set fire to the outer decorative lining, good fillers will not support combustion or melt and emit toxic smoke.
  • Durability. The most optimal materials steadfastly retain their shape and thickness despite temperature changes, so that the insulation inside the sash does not have to be changed after 5-10 years.

The best economy class fillers

It is not entirely correct to compare all types of insulating materials at once, due to the large difference in cost and different places of operation, therefore they are divided into two categories according to the class of the doors themselves. The economy version contains corrugated cardboard inside the web, which is a set of strips glued with ribs to a solid sheet. The wavy shape of the vertical elements resembles a honeycomb, which contributes to the division of the internal space into cells and the creation of separate chambers with air. This protects against the rapid passage of sound and heat transfer. Such doors are suitable for the cottage or as technical ones.

But for an apartment in the entrance hall on the ground floor, where water vapor comes from the basement, the best filler for a metal door is expanded polystyrene, since it has low vapor permeability, and absorbs water only at close contact, but not at a distance. The material is obtained from styrene filled with gas dissolved in the polymer mass. Due to this, increased many times in volume, it is light and has sufficient height to fill the internal space of the doors. The substance is resistant to fungi and microorganisms. Designed for 60 years of operation.

Styrofoam refers to a variety of economy filler obtained by a similar technology - polymer foaming. The density of the material depends on the type of plastic used as raw material. The cellular structure with thin walls does not transmit sound vibrations well, and the composition of 98% gas in sealed capsules does not allow low temperatures to pass from the iron. The main advantage of polystyrene is thick plates that do not absorb water. This is a good option for an apartment door or a private house in a warm region.

The best fillers for elite class entrance doors

More expensive products have filling with enhanced insulation characteristics. The best front door insulation for noise reduction and durability is rigid foamed polyurethane foam, because it consists of 90% inert gases that solidify in plastic walls. The substance is initially poured into the sash in a liquid state and fills all the cracks. This technology allows you to create an independent frame that holds the shape of the insulation for a long time and completely blocks the passages for sound penetration. Therefore, in the entrance or on the street for sound insulation, it is better to use canvases with polyurethane foam.

When it is required to protect the entrance from freezing in a cold region, mineral wool is the best insulation for entrance doors, due to its high density and the possibility of being placed not only inside the leaf, but also in the box. The fleecy structure has the ability to shrink a little when laid in the sash and burst itself from the inside, tightly pressing against the metal. Thousands of fibers trap air between themselves and reduce heat transfer. Sound waves hitting them are completely absorbed. The material is easy to cut, and it can be laid in a box, which eliminates drips of condensate and icing.

The Reliable Doors company has in its assortment products with all the listed types of fillers for entrance doors. Here you can choose products for summer cottages, apartments and private houses with permanent residence. Through feedback, it is convenient to clarify additional questions on the characteristics of heaters.
