Penoplex

In the first place of our rating is the penoplex that makes Tekhnikol company and others. The material is rectangular plates of extruded polystyrene foam manufactured at high temperature and extruded under pressure from extruder. This provides a uniform structure and a closed shape. cells, thereby reducing the thermal conductivity insulation for the balcony. The indicator is 0.032 W / mK and is reliable protects walls from freezing in winter and overheating in summer. Buyers in the reviews note that the insulation is easily cut with a construction knife and maintain a straight line is not difficult. Penoplex with cross section for sale 30, 50, 80 or 100 mm, which is convenient for selection, depending on wall thickness on the balcony.

We put insulation in first place in the ranking not only due to its high insulating properties, but also due to its convenience styling. Each panel has a L-shaped edge, therefore it is assembled tight as a constructor. This eliminates the formation of bridges. cold “and requires foaming joints only in corners or place contact with the bearing wall of the house.

Penofol

Rating: 4.9

Penofol

The second heater for the balcony from our rating represents a sheet material in a roll. Flexible structure convenient for compact transportation and laying on uneven surfaces. Penofol is made from foamed polyethylene, characterized closed cells that reduce the transfer of heat or cold. By thermal conductivity, it is inferior to the leader of the rating – its indicator is 0.049 W / mK, but the insulation is much thinner, which does not require the creation of a wide space inside the wall. Let out insulation with a section of 3, 4, 5, 8 and 10 mm. It is environmentally friendly product related to the combustibility class G1, i.e. completely not supporting the spread of fire. Buyers in reviews share, that it’s very easy to pack penofol – even newbie.

According to our experts, insulation for a balcony is worthy of a place in the rating due to the presence of a foil layer. Such a screen has the cross section is 14-20 microns and can be on one or two sides. Thanks aluminum in the composition, the insulation effectively reflects direct solar rays falling onto the balcony and does not allow it to overheat summer heat. Thermal reflection has an indicator of 97%.

Advantages

  • a thickness of 3-10 mm does not “eat up” the inner space a balcony;
  • takes any shape of the surface;
  • easy to cut with scissors;
  • you can cut the necessary segment with curved lines;
  • suitable for operation at -60 … + 100 degrees.

disadvantages

  • you need to buy a whole roll;
  • vapor permeability is almost absent – 0.001 mg / mh Pa;
  • little delay noise (only 20 dB).

Isolon

Rating: 4.8

Isolon

The third place in the rating is occupied by Isolon insulation, which made by foaming polyethylene. From the first sight he It differs in non-crosslinked granules, which are then crosslinked physically. It turns out a cellular soft structure that takes a good shape surface. By consistency, it resembles a heater for jackets, only tougher. Isolon is great for warming. balcony, since its thermal conductivity is 0.036 W / mK. At With a density of 30 kg / m3, the material weighs very little. For sale insulation in rolls with a width of 1.2 m and a length of 12.5-20 m. the cross section is from 2 to 10 mm, which helps to insulate the balcony, and not create thick walls that take up usable space. The substance is suitable for use at a temperature of -40 … + 70 degrees.

Our experts included insulation in the rating due to availability extra sticky layer. It closes with paper from the factory, and during installation opens and provides reliable fixation to the walls the balcony. This technology has many positive reviews. masters, because it simplifies installation. The adhesion force at an angle of 180 degrees is 1.0-5.0 N / cm.

Advantages

  • different thickness from 2 to 10 mm;
  • does not occupy the interior space on the balcony;
  • easy to cut in a straight line and curve;
  • Do not fly in the air when laying;
  • easily repeats surface irregularities.

disadvantages

  • have to buy a roll;
  • easy to damage when stretched;
  • may be accidentally punctured during installation.

Mineral wool insulation

Rating: 4.7

Mineral-cotton insulation

The fourth ranking position belongs to mineral wool. It made of rock or slag, therefore called basaltic. Insulation for a balcony in slabs or rolls with a cross section from 30 to 200 mm, which is convenient for selecting the value warming. The thermal conductivity is quite low and amounts to 0.035-0.040 W / mK. The substance varies in density from 15 to 200 kg / m³. But users in the reviews warn that the outdoor the lining of the balcony should be well insulated from water leakage, otherwise mineral wool will lose its shape and its heat-saving properties. Mineral wool does not prick, but work must be carried out in a mask, so as not to swallow the villi.

We included insulation for the balcony in the rating because of its more Affordable prices compared to competitors above. Still mineral cotton wool, in addition to thermal insulation, provides high noise insulation – on the balcony It will be quiet and comfortable, despite the cries of children or the sounds of cars for by the windows. Heater vapor permeable – accumulated condensate will be go outside without destroying the finishing materials.

Advantages

  • absolutely does not burn and does not emit toxic smoke in contact with by fire;
  • does not form bridges of cold;
  • easily cut into the necessary segments;
  • does not require an exact fit (you can crush the excess parts in corner);
  • allows the passage of steam out.

disadvantages

  • when laying in the air, villi fly;
  • loses shape when wet;
  • takes up a lot of space over the cross section;
  • large volume during transportation.

Styrofoam

Rating: 4.6

Styrofoam

The fifth step of the rating of heaters for home placed the old, good polystyrene. The substance is released from polymers by foaming. 98% of the material consists of air, and the remaining 2% are plastic masses in the form of a shell of cells. Thin Partitions promote low heat and sound transmission. Produced goods in plates with a cross section of 20-50 mm. You can cut it long knife or hacksaw, but it crumbles a little. Masters in reviews advise the joints of the plates and the edges to blow out with foam so that to exclude the formation of “cold bridges”. The advantage of insulation is increased ease. It does not create a load on the carrier construction. You can even finish polystyrene on the outside with plaster (which you won’t do on mineral wool or isolon), therefore The interior of the balcony is expanding.

Our experts added insulation to the rating because of its cheapness. The price of polystyrene is much lower than competitors. Material has good elasticity – compressive strength is 60 kPa, therefore, if accidentally push the balcony wall with a solid object, then it does not will be doubted. More polystyrene retains its shape without additional substrates, which simplifies installation.

Advantages

  • affordable price;
  • maintains its shape for a long time;
  • service life of 20-30 years;
  • no phenol and formaldehyde in the composition;
  • increased mechanical strength.

disadvantages

  • crumbles during cutting;
  • apply on the balcony in combination with foam;
  • absorbs water;
  • when burning, it smokes a lot.

Polyurethane foam

Rating: 4.5

Foam Polyurethane

Last place in the ranking is gas-filled plastic at polyurethane based. Insulation for the balcony is 85% gas. Depending on the type of raw material (polyurethane), the resulting material may be hard or soft. Sale of goods in sheets and rolls with section from 10 to 80 mm. There is a technology for spraying substances in liquid form immediately on the insulated surface, but for this you need Call a special service with the device. Density foamed polyurethane is from 300 to 650 kg / m³, which exceeds the performance competitors. Shore hardness ranges from 75 to 98 units. Masters in reviews praise the material for being cut with approximate accuracy – excess parts are easily compressed to enter in size, and the cracks can be repaired with residues.

The experts decided to attach the insulation to the rating because of its slight shrinkage in compression. The material retains its shape despite on load and pressure. The second advantage of insulation is resistance to light – the substance does not dry out when penetrated rays through the cracks in the finish, which is practical on balconies, located on the sunny side.

Advantages

  • moderate flexibility;
  • well cut with a knife or scissors;
  • resistant to dynamic loads;
  • operating temperature -20 … + 80 degrees;
  • low shrinkage under pressure.

disadvantages

  • smokes when burning;
