Varieties of bulk insulation and their use

Insulation is essential for maintaining a comfortable and energy-efficient home. Additionally, bulk insulation is particularly useful and adaptable among the different kinds of insulation that are available. Bulk insulation slows down the transfer of heat by enclosing air pockets inside its structure. We’ll examine the various types of bulk insulation in this post, along with how using them can raise your home’s comfort and energy efficiency.

Fiberglass rolls or batts are among the most widely used forms of bulk insulation. These are installed between wall studs, ceiling joists, and floor joists and are made up of long blankets of glass fibers. Fiberglass insulation is a well-liked option for both do-it-yourselfers and licensed contractors due to its reputation for affordability and simplicity of installation. Its fluffy structure traps air, effectively reducing heat transfer.

Cellulose insulation is another well-liked choice. It is created from recycled paper fibers that have been chemically treated to resist fire. Attics, wall cavities, and other spaces can be filled in with cellulose insulation, which can be sprayed or blown into to create a seamless barrier against heat transfer. Many environmentally conscious homeowners choose it because of its superior thermal performance and eco-friendly composition.

Spray foam insulation provides better air sealing and thermal resistance for those looking for high-performance insulation. This kind of insulation is sprayed on as a liquid that solidifies into a dense foam after expanding to fill in gaps. By forming an airtight seal and obstructing heat transfer, spray foam insulation prevents air leaks. Even though it’s typically more expensive than other insulation options, the investment is frequently justified by its remarkable energy-saving advantages.

Another creative solution that uses reflective surfaces to lessen radiant heat transfer is reflective insulation. In order to reflect heat away from the living space, reflective insulation is typically installed in attics, walls, and floors. It is typically made of aluminum foil laminated onto paper or plastic substrates. Reflective insulation contributes to year-round indoor comfort by reducing radiant heat gain in the summer and heat loss in the winter.

Fanding heater for the floor, walls and ceiling

Fallow thermal insulation is made up of different density fibers or granules. Because it is so simple to install, thumbner insulation is most frequently used for floors. Specialized equipment is used to spray the material in the form of a solution for wall insulation.

Advantages and disadvantages of the material

The user-described advantages boil down to four main points: low thermal conductivity, lightweight, ease of installation, and environmental friendliness.

Weak stability prior to mechanical load, moisture, and fire are drawbacks. The majority of these materials shrink with time and require ventilation.

Varieties of bulk insulation

Insulating materials are categorized based on multiple indicators:

• Nature (natural or synthetic).
• Structure (grain or fibrous).
• Methods of installation.

Crucial! Typically, a dispersed insulation enters the bags upon sale.

Ceramzit

Keramzit is a product of clay firing that has a fraction of up to 45 mm. For floor and ceiling applications, 10–20 mm grains are utilized as thermal insulation; for attics and basements, 20–40 mm grains are used.

• Strength can reach 0.5–5.5 MPa;
• Thermal conductivity is in the range of 0.07–0.18 W/m*K;
• Water absorption – 8–20 % per day from the total mass.

For its low volumetric weight (an average of 400 kg/m3), durability, environmental friendliness, resistance to fire, moisture, and chemical reagents, and strength, the rafting insulation is released. It is made of concrete and poured onto the base like a floorboard.

Crucial! In order to guarantee the necessary insulating qualities, a layer ranging from 10 to 40 cm must be formed.

Perlit

The process of creating a fining heater involves heating volcanic rocks that resemble glass while adding useful ingredients. Grain fractions ranging from 0.16 to 5 mm are used in construction.

Features of perlite technology:

• Strength 0.1-0.6 MPa;
• Thermal conductivity 0.043-0.093 W/m*K;
• Water absorption 20-400%.

Crucial! Thermal insulation has an average filling density of 270 kg/m3. The benefits include vapor permeability, inertia to biological defeat, non-combustibility, and environmental friendliness. Because of their increased hygroscopicity, the granules are ruined by frost and cannot withstand it. During the perlite’s drying process, dusting and the creation of heights on the decoration are observed. Potential shrinkage surpasses a 10% indication.

Vermiculite

Vermiculite is an organic mineral substance. Hydrosludes, or silicate breeds, are used as a foundation. At +1200 °C, raw materials are heated.

• Strength of 0.3-0.7 MPa;
• Thermal conductivity 0.045-0.053 W/m*K;
• Water absorption up to 400%.

On average, the bulk density is 650 kg/m3. The benefits include low shrinkage, good acoustic qualities, inertia to fire and aggressive conditions, and low cost. Under practically all finishing floors, the material is laid.

Crucial! Ensuring the conditions for the removal of moisture from the insulation is imperative.

Wood sawdust

The cheapest insulation is said to be made of wood dust and chips. The primary benefits include low heat conductivity (0.07–0.09 W/m*K), environmental friendliness, and light weight (270 kg/m3).

However, there are differences in high water absorption, low resistance to biological activity, and fire.

Granular polystyrene foam

A fraction of 1–8 mm of filling polystyrene is synthetic in nature. Light granules have a density of up to 300 kg/m3 and a low thermal conductivity of 0.032–0.044 W/m3. The two biggest drawbacks are low mechanical strength and combustibility.

Aerated concrete crumb

Crushed porous concrete is environmentally friendly, lasts for many years, and resists frost with minimal water absorption. Granules as small as 30 mm have a density of up to 680 kg/m3, are able to breathe, do not burn, or rot, and have a thermal conductivity of up to 0.12 W/m*K.

The only flaw that stands out is dust dust.

Foam glass in granules

With additions, silicate glass cells essentially never absorb moisture, last over a century, and withstand mechanical stress and natural occurrences. 0.04-0.08 W/m*K for thermal conductivity and up to 4 MPa for strength.

The high price, relative severity, brittleness, susceptibility to alkalis, and inability to breathe are among the drawbacks.

Granular foam

The most common form of modified polystyrene is in the form of flakes. The material has good vapor permeability, is non-toxic, does not burn, and does not absorb moisture like the analog. Density ranges from 8 to 28 kg/m3, and thermal conductivity is between 0.035 and 0.047 W/m*K.

However, physical toughness and defense against outside attackers are lacking.

Pulp heater – Ecowata

Insulation made of east basalt is non-toxic. When wet, minimum losses of insulating qualities are distinguished, which is advantageous in frame construction. 0.035 W/m*K is the thermal conductivity.

Because of the anti-pirens and antiseptics in the composition, good acoustic and protective qualities are also notable. This is especially true for the decoration of the roof, attic, and extensions. One of the drawbacks is shrinkage.

Which is better to use, the main selection criteria

Moisture resistance and insulating indicators are the main factors in insulation selection. Inertia to operating conditions and environmental friendliness are taken into account. The material’s appeal to rodents is an important consideration for a private residence.

Crucial! When installing bulk insulation for walls or finished flooring, considerations such as shrinkage and strength must be taken into account when selecting the insulation.
