6 best heaters of an entrance door

Review of the best according to the editors. About the selection criteria. The the material is subjective, is not advertising and is not serves as a guide to the purchase. Before purchase is needed consultation with a specialist.

Metal entrance doors reliably protect an apartment, house or commercial building from burglars due to the thickness of the steel sheet from 1.0 to 4.0 mm. Such an obstacle is more difficult to crack by force. But due to the increased thermal conductivity of the metal, housing will be faster cool, so you need a quality filler, which is important equip the door leaf. Our experts have prepared the TOP-6 insulation materials with their characteristics and reviews, thanks what you can figure out what insulation for the front door it’s better.

Mineral wool

Rating: 5.0

Mineral wool

In the first place, experts put mineral wool, manufactured according to GOST 31913-2011. She represents thousands thin fibers that form an air space between them, which creates a barrier to the transfer of temperature from the outside front door to the inside. This products match international standard EN ISO 9229: 2007. Mineral wool It differs in the type of fiber orientation and density. Index thermal conductivity is 0.032-0.038 W / mK. Mineral wool made of molten glass, blast furnace slag or other raw materials. In the first case, she will inject a little, which will require hand protection when placing a heater. It’s important to work anyway in a gauze bandage to prevent small fibers from entering respiratory system.

Experts consider this insulation to be the best, since cotton wool is capable of skip steam 10 times better than other materials (indicator 0.003 mg / (mchPa)). This is true if the front door is next to the kitchen where something is cooked regularly. On the sash less drops of condensation will collect.

Advantages

  • insulation does not burn;
  • there are various types in thickness;
  • does not leave “bridges of cold”;
  • Does not create a load on the frame.

disadvantages

  • high price;
  • glass wool is pricked;
  • it is necessary to carefully close the gaps in the metal in case of installation doors facing directly to the street.

Basalt slab

Rating: 4.9

BASALT PLATE

In second place is a “related” product – a basalt plate, made from molten igneous rocks. Builders this insulation is also called “stone wool”. The material is similar in structure with mineral wool and consists of many fibers. They can be directed vertically, horizontally or in different side. The latter type is considered the best in thermal insulation. Yet when choosing this insulation it is important to consider the density, where There is an indicator from 10 to 150 kg / m³. Basalt sold plates with a thickness of 25 to 200 mm. Masters in reviews are advised to buy insulation for the front door with a cross section of 50 mm and press it with sheets metal inside the sash. But for even distribution over internal cavity, it is important to provide support (if the door is small transverse stiffeners), so that the insulation does not go astray gradually down.

We recommend this insulation to enhance fire security. Entrance doors with basalt slab inside efficiently delay high temperature if the external decorative panel MDF scorching. Another stove will not let the fire go to the protected side. Certified fire rated doors (E30, E60) are manufactured with basalt slabs inside.

Advantages

  • does not burn;
  • You can tightly lay the plates together;
  • easy to cut;
  • there is a section from 50 to 200 mm.

disadvantages

  • hygroscopic;
  • need props to fill the interior canvases.

Polyurethane

Rating: 4.8

Polyurethane foam

Continues the review of polyurethane obtained from polymers, combined with a urethane group. In its properties, it resembles rubber, but more durable. For entrance doors it is applied polyurethane foaming, in which the solid material is only 3% of the total mass. The remaining 97% is air. Substance served in the door leaf from a special apparatus. After solidification it gets a mesh structure, where 94% of the pores are closed. Is not allows the temperature to quickly switch from one side to the other. The insulation does not need to be supported by spacers – it will be tight stay in place all life. Masters in reviews like that unlike mineral wool and basalt slabs, polyurethane is not afraid of water. If on the front door (corner joints with cracks) rain falls, the insulation will not hesitate inside. it allows the use of filler in the leaves at the entrance to commercial or administrative buildings that often leave open due to the high traffic of visitors.

Our experts consider the material to be the best in filling quality. the inner cavity of the front door. By feeding in liquid form, the substance flows into each crack and adheres firmly to the walls framework. This completely eliminates exposed areas where cold could be transferred to the room.

Advantages

  • the insulation has a neutral smell;
  • not affected by fungus and mold;
  • resistant to alkali acids;
  • not afraid of water.

disadvantages

  • you need sophisticated equipment to fill the sash;
  • Accuracy is required so as not to flood the lock.

Cork agglomerate

Rating: 4.7

Cork agglomerate

This insulation is made from bark of bark of trees, which is pressed into plates at a temperature of 350 degrees. Thanks such technology there is no need to add glues and other chemicals – to bind enough natural resins to wood. The result is an elastic material with good recoverability after bending or compression. Cork agglomerate for entrance doors you can buy with a thickness of 10, 15, 20, 25, 40 or 50 mm. The masters in the reviews like the ecological purity of the insulation and ease of cutting. But they advise to “plant” for better fixation. insulation on glue. The thermal conductivity of the sinter is 0.040 W / mK, which is almost not inferior to mineral wool. Exploit it possible at temperatures from -180 to +110 degrees.

According to experts, this insulation is the best in terms of elimination noise and vibration. This effect is achieved due to increased sinter density ranging from 95 to 130 kg / m³. Noise reduction up to 60 dB is possible behind the front door. It is worth paying attention to the insulation attention to residents of small families or those whose housing located near the highway, rail or tram ways.

Advantages

  • thickness varies from 10 to 150 mm;
  • environmentally friendly material;
  • no unpleasant odor;
  • Does not create a load on the frame.

disadvantages

  • high price;
  • supports burning;
  • additional fixing of panels is required;
  • cold bridges may form at the joints.

Foiled Isolon

Rating: 4.6

Foiled Isolon

Another popular material for warming metal inputs doors is a foil isolon. He is physically crosslinked polyethylene foamed. As a result it turns out a light insulation with closed air capsules inside, having a relative elongation of 100%. Goods are produced in rolls and happens to be 10-30 mm thick. The product is divided by density from 28 to 66 kg / m³. Thermal conductivity is at a good level of 0.037 W / mK. The masters in the reviews like foil Isolon self-adhesive backing – for fixing to the inside of the sheet the entrance flap does not require foam or sealant. Enough to separate paper protection and tightly press the insulation.

The advantage of this insulation is a layer of foil, glued to one side. She acts as a screen, reflecting heat back inside the room, and returning the cold outside. If in front door place two layers of foil isolon metal layer to each other, then it will divide the inner space in two. Get doors with thermal break their hands that will cost several times cheaper than store ones.

Advantages

  • reliable overlap of joints;
  • easy to cut;
  • there are options with a self-adhesive base;
  • reduces noise by 33 dB.

disadvantages

  • supports burning;
  • has a water absorption of 0.86% per day;
  • gives off an unpleasant chemical smell.

Styrofoam

Rating: 4.5

Styrofoam

This is the most popular insulation for doors of economy class. Foam is made from foamed polymers, receiving after solidification cellular structure. The walls of each capsule are very thin, therefore, negative and positive temperatures cannot quickly cross them to the other side. Thermal conductivity slightly inferior to mineral wool and is 0.041 W / mK. The insulation is available in plates with a thickness of 15 to 200 mm, where for 20–50 mm section will be optimal for metal entrance doors. The material is available in three density options: 15, 25 and 35 kg / m³, which affects the degree of sound insulation. In the reviews, users are satisfied low weight of insulation (cube has a mass of 10 kg), small water absorption, lack of smell.

Experts considered polystyrene the best for warming the front door at cost. An ordinary sash with dimensions of 2000×900 mm can insulate with a layer of 50 mm thick for about 150-200 rubles. Yet This material does not lose shape, unlike cotton wool, so inside the canvas does not require additional jumpers to maintain.

Advantages

  • affordable price;
  • a light weight;
  • not afraid of moisture;
  • there is a different density and cross section.

disadvantages

  • “cold bridges” may remain;
  • burns;
  • gluing on foam is required;
  • crumbles when cutting.
