ideal building material, as well as perfect insulation - the dream is still not translated into tangible reality.Numerous attempts to create a high quality thermal insulation for construction equipment designs have not yet led to a productive outcome.Wishing to build suburban housing city apartment or a layer of insulation still have to choose carefully weighing the disadvantages and advantages of each of the strong materials.Putting in a certain amount of negative and positive qualities, the consumer decides whether he will approach or mineral wool is better to buy a practical light foam.


work of engineers and chemists, hard working people on the invention immaculate insulating material, yet can not be considered unproductive.The n

ew generation of heaters differs significantly from the historical antecedents of a significant number of technical indicators.In addition to improving the technical characteristics of the area development extended to ensure ease of installation, increased durability.Successes were, but to choose and evaluate the benefits and negative aspects still needed.

Criteria for evaluation of mineral wool and foam ↑

Buyer, ie the owner of the residential or commercial property under construction country house or a small garden are interested in such as materials for thermal insulation,like:

  • minimum performance thermal conductivity does not vary depending on the complexity of the environment;
  • strength, lack of thermal expansion, preservation of structural links when exposed to moisture;
  • good job in the high and low temperature operation;
  • low moisture absorption;
  • operational long-term;
  • insignificant proportion of high insulation parameters;
  • possibility of rapid installation in any season period, ease of installation;
  • resistance to biological attack;
  • security, justifying the possibility of using for insulation housing.

Comparative evaluation of mineral wool and foam for each of the above points will enable a rational approach to the problem of choosing the best material.

For proper orientation of selection of insulation you need to decide in which of the parameters for a specific customer are fundamental.

mineral wool and its characteristics ↑

builders Called "mineral wool" stone wool - insulation material with a fibrous structure chaotic.Get it by melting igneous and metamorphic rocks, metallurgical wastes and mixtures thereof.Properties and genesis of rocks, used in the manufacture of insulation, determines the main advantages of the mineral insulation:

  • resistance to fire,
  • resistance to biological negativity,
  • low thermal conductivity.

most common and popular stone in the construction view of a heater is basalt wool and mats made based on it.Stone insulation can be made of slag, diabase, porphyry, gabbros and other minerals consisting of silica, including oxides of magnesium and iron.

Mineral wool insulation does not burn, does not melt even at a temperature of 1000 ° C, have the ability to prevent the spread of fire.Wadding of stone - a great barrier to interdict the passage of heat.However, in a wet environment mineral wool may lose its characteristics.The porous insulation passes pairs and can absorb moisture.When the amount of water in the material reduced thermotechnical priorities as water, is an excellent conductor of heat loss contributes.But thanks to the property to pass the evaporation of mineral wool is actively used for arranging homes of wood.After all, the advantages of genuine natural organics is the ability to spontaneously display household pairs of contour of the building, and any other type of heater is able to strip the wood of one of the main advantages of it.

repellent properties and bearing capacity ↑

Among stone heaters highest water repellent different basalt wool.She passes a minimum amount of moisture, because the material often used for thermal insulation of swimming pools, saunas and baths.It performs insulation of pipelines and equipment engineering services.The chaotic arrangement of fibers of basalt wool provides a high strength, the ability to steadfastly resist powerful loads.

Based on the strength properties basalt products used for the arrangement of the lower floors and floor systems, combining floor and ceiling.For the arrangement of the floor with the same intensity used porous polystyrene foam and other types of synthetic insulation.In wanting to equip insulation overlapping the natural question arises: "Which is better suited for floor insulation: mineral wool or foam?" Definitely no one answer, but the scale of comparison is often inclined towards rock wool because of the affordable prices and features prevent the passage of sound vibrations.And on the strength of the original parameters of both types of heaters are virtually equal performance.

foam is produced from a suspension of the polymer by foaming than due to its low specific weight.Lightweight insulation is highly durable, as its structure is a set of small, closed cells, interconnected in a specific way.Each of the original closed areas, which is located inside the gas or air, takes some of the load.Together, they have a strong resistance to static and dynamic effects.

structural strength and reliability in the insulation provided by the technology of sintering pellets in the solid material.Relations between the granules do not collapse during the entire period of use.Stone wool products in the long-term yield foams.With prolonged use especially in a critical temperature, even the most durable basalt wool, which occupies a leading position in a number of mineral insulation can flake, crumble and become deformed.

Specificity of the foam structure predetermines the technical advantages

In the manufacturing process the foam insulation, 90% consists of air is formed in the plates, blocks, modules for permanent formwork, architectural and decorative elements and other types of products.Has structural strength and density of the foam is extremely easy to install, thereby significantly reduced time work on the device insulation.

Operational Safety ↑

In order to combat the flammability of plastic insulation of the composition is enriched with additives that prevent burning.Again the question: foam or mineral wool provide complete security?Manufacturers argue that according to the criteria of fire these materials are equivalent.In the event that the seat of a fire, these two options work the same insulation, as are a group of self-damping.

in the mineral insulation is used phenol-formaldehyde binders that emit harmful volatile substances.With the loss of structural links containing silica wool can also spread the silicate dust, cleanse the lungs by means of which also no one has yet invented.Certified insulating mineral cotton material is definitely suitable for housing arrangement, but artisanal products should be treated cautiously.If foam or mineral insulation will serve as the middle element of the well masonry or placed under a concrete screed floor, the safety criteria are irrelevant.

Light weight and easy installation ↑

Products foam is much easier to stone wool products.Cruiserweight mineral insulation impact during transportation.The cost of loading and delivery to the construction site, unloading products from mineral wool above the payment of similar processes required for the transport of products from foam.Lightweight foam insulation is more convenient to install than mount mats made of basalt insulation, which affects the rate of production of works and payment for expensive manual labor.

New modifications foam

foam insulation significantly increases the weight of constructions, means for home do not need to enhance the bearing capacity of the supporting base.When building insulation basalt wool its weight need to be considered.Moreover, the need to rely on the weighting of mineral material during operation at high humidity, because of what the hygroscopic rock wool less frequently used for insulation of equipment plinths, basements and foundations, in contact with water-saturated soils.

Consumers wishing to conduct thermal insulation of housing, commercial or industrial buildings efficiently and economically, a comparative analysis of the materials will help determine the choice.The unequivocal answer to the question, what is better foam or mineral wool, does not exist.Each of them has its drawbacks, and a considerable list of benefits.Focusing on the customer personally meaningful moments, you can choose the best option.
