By basalt crumb (backfill) is meant crushed scraps remaining from basalt wool. Such material is successfully used during backfill of inter-wall voids, arrangement of floors, sub-premises, roofing. The material is characterized by incombustibility, vapor permeability (not prone to moisture accumulation), noise insulation properties, natural origin. In addition, the material does not lend itself to decay.
Brief description of the material
Basalt chips - bulk / blowing / stuffed wool, insulation with a high thermal insulation property, a relatively new, economical and easy-to-use mineral wool-based material. The crumbs are obtained by dispersing (grinding) mineral wool plates and mineral wool waste using special processing units characterized by high production capacity.
Material quality
The material is characterized by such qualities:
- high heat-saving indicators;
- Cold bridges do not form when using this material;
- the possibility of warming the surface of any thickness;
- convenience in warming inaccessible or inaccessible places;
- affordable price;
- convenience in storage and transportation;
- compact and reliable packaging;
- vapor permeability and noise isolation.
The use of basalt chips allows you to get and insulate even hard-to-reach parts of the house, floor, ceiling, attic, etc.
The material is delivered to the market in bags, in a loose and loose state. Compared with other options for existing thermal insulation (slag, sawdust, expanded clay and others), the material surpasses them in technical characteristics.
Warming the house with basalt chips
Backfill is used for insulation of buildings of any type: residential and industrial buildings. The main condition put forward for the implementation of the insulation project is the presence of a minimum wall gap of a thickness of up to 4 centimeters.
Backfill is fed under the surface layer using a special blowing unit feeding crumbs under pressure into the cavities formed between the internal and external walls. As a result, this allows achieving the “thermos” effect, which contributes to a longer heat preservation by the house, and, therefore, saving on resources that were previously spent on heating the building.
Choosing the option of warming the house with basalt chips, it is worth noting that this technology of insulation significantly exceeds the thermal insulation when using the same foam backfill in almost all respects.
The main advantages of the material
Among the positive qualities are the following:
- raw materials of natural origin (basalt rock melt product) that does not contain blast furnace slags or additives;
- high fire safety. The material does not burn and, on the contrary, prevents the spread of flame on the surface, due to which it is recognized as a high-quality refractory insulation;
- the fibrous structure of the crumb allows during the pneumatic blowing to form a layer with a density of 75-80 kg / cubic meter, which is equivalent to the effect of a monolithic plate;
- The main field of application of mineral wool basalt chips is the insulation of walls, ceilings, attics, and inter-wall space.
It is these qualities described above that make home insulation of this kind of material the main and preferential choice of buyers. The consumer mentions in his reviews the high quality of the basalt backfill produced by domestic companies, notes the affordable price of the goods. This gives the basalt insulation such popularity, because in its choice the potential buyer primarily focuses on what the person who tried the material actually says.
Why insulate a house with basalt filler?
Based on the above features and advantages of the material, we can say with confidence that basalt filling belongs to the category of high-quality heaters that retain their performance indicators regardless of type.
The fibrous structure gives the material special elasticity and mechanical strength in use. The heat-insulating properties of basalt backfill remain unchanged for a long period, and the material itself does not shrink.
The advantages of insulation
As a result of using insulation - basalt chips, the client receives an effect in the form of:
- reduction of heat loss in the cold season (basalt backfill is up to 25% more effective than polystyrene crumb in terms of thermal insulation);
- lowering the cost of heating the living space;
- additional sound insulation;
- high vapor permeability and water-repellent properties, which prevents the accumulation of condensate;
- long life due to the inorganic composition of the material, which is not susceptible to decay and fungal infections.
Features of wall insulation of the house with basalt filling
The technology for blowing the inter-wall space with basalt chips is as follows:
- Wall preparation. Drill holes with a diameter of up to 45 mm, from 8 to 12 pieces on each wall (the number depends on the area of the surface to be treated).
- Blowing The process takes place using a special unit. Which, under pressure, injects the crushed material into the cavity so that the layer of basalt wool lies evenly, forming a dense, but at the same time loose structure, which contributes to more efficient heat storage in the room.
Please note that work is available even in the cold season. Blowing of inter-wall voids contributes to effective gas savings of up to 60%, and this indicator depends on the size of the inter-wall air gap, the selected type of material (basalt wool or foam plates), the quantity and quality of heated surfaces.
As buyers of this material and those who have already tried all the advantages of basaltic filling on their own experience describe in their reviews of basalt crumb, isolating the walls with this material is profitable, because paying for a quality home improvement once, you get a comfortable and warm home for decades.
