Best High Temperature Fire Resistant Thermal Insulation for 2020

When you need to buy insulation for your home, then one of the best options is to purchase fire-resistant, non-combustible insulation. So a person will protect himself, because the selected material will not succumb to open fire and will withstand almost any temperature. However, it is important to choose the right product, because not all products on the market have excellent durability. Therefore, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best high-temperature fire-resistant thermal insulation for 2020.

Why do you need a non-combustible insulation and what to look for

Fire resistant thermal insulation is essential for every home because it not only insulates the building from the effects of low temperatures, but also gives safety to the user. This reduces the chance of accidental fire to 0%. If earlier such heaters were a novelty, then in 2020 there are hundreds of models on the market that are suitable for household stoves, fireplaces, chimneys, baths, while their efficiency remains at a high level.

Oxygen index

The first selection criterion is the oxygen index. The characteristic indicates the minimum amount of oxygen that is present in a unit volume of thermal insulation. In total, there are three types of heaters, which differ in flammability threshold:

• 40%. This category includes composite polymers;
• 31%. Glass wool, basalt wool and other fibrous and cellular insulation;
• 20%. It is worth knowing that such products burn well in the air, so their use is unacceptable in fire-hazardous places.

Features:

When choosing a fire-resistant heat-insulating substance, it must have the following parameters:

• Burning with visible flame is allowed, but it should last no more than 10 seconds. This will prevent the fire from spreading to other areas, which will prevent a large fire from occurring.
• During combustion, the maximum temperature of the material used should not rise above 50 degrees.
• In addition, it is important that the thermal insulation does not lose half of its volume and mass during combustion.

If all these points are observed, then the user can be confident in the selected material, because he will never let him down.

What are the types of fire-resistant insulation

There are hundreds of insulation models on the market, each with a unique composition and can be versatile or site-specific. Therefore, you need to know which ones are suitable for pipes, and which ones are suitable for the house, stoves, fireplace, etc.

Loose

This species is represented by small crushed stones. They are poured into a special place in the building structure. Most professionals advise using bulk materials of different fractions in order to increase their effectiveness, because large products will create excellent thermal insulation, small ones will fill the void that forms between them.

• Expanded clay. Eco-friendly material that is completely safe for humans and consists of natural products. The main element of the composition is clay.The product is suitable for use in hard-to-reach places. The advantage of this option is high moisture resistance. This product is more often used for insulating fire hazardous facilities in an industrial area.
• Expanded vermiculite. The main element of this product is hydromica. To make it safe to use, it is subjected to high-temperature firing during production. This product is used to provide thermal insulation for small structures and low-rise buildings. The main advantage of the material is natural ingredients, a high rate of biostability. The only drawback is the instability to moisture.
• Perlite. One of the popular products that is used for thermal insulation in many places with low moisture content. The material is made on the basis of volcanic glass, thanks to this solution, the product is lightweight and provides low thermal conductivity.

Honeycomb

At first glance, such thermal insulation looks more like frozen soapy foam, but with a high heat resistance. Foam glass is very popular in this category. For its manufacture, glass crumbs are used, which are processed with high temperature and sintered with coal. The advantage of such a product is its durability (so even a cheap product has an operational performance of 60 years, for more expensive models it reaches 100 or more years). In addition, foam glass has high mechanical strength and low thermal conductivity.

Its effectiveness has been proven in professional and amateur experiments. This material does not ignite until 1600 degrees or after. All that will happen at record temperatures is the melting of foam glass, which is accompanied by the release of dangerous toxins. Due to its heavy weight, the material is used to insulate basements.

Fibrous

Popular thermal insulation, which looks like cotton wool, because it consists of small white fibers, which are randomly located. Such insulation is available in rolls and mats, which is a convenient form factor for most buyers.

Mineral wool can be sold as sheets. This product has a slight stiffness, unlike similar products in mats. In total, 3 types of this material have been distributed:

• Glass wool. The material can withstand temperatures up to 500 degrees, while maintaining all the nominal technical characteristics: service life, low weight, thermal efficiency. However, to work with such a material, you must have special protection because glass wool negatively affects the mucous membrane and digs into the skin, and the product is also prone to shrinkage.
• Basalt wool. This product is based on rock fibers, which are heated to over 1400 degrees during production. For this reason, such a product can withstand temperatures over 1000 degrees without much difficulty. Both 10 years ago and today, this material is in great demand for insulating objects. The advantages include: a small value of moisture absorption, vapor permeability, environmental friendliness and biostability.
• Ecowool. The material consists of recycled cellulose, which has undergone fire retardant processing during the processing stage. The product has a low weight, is not harmful to the body and has a low insulation value. The main disadvantage is low moisture resistance.

Liquid

The material is applied by spraying onto a specific surface. After several hours, a solid mass is formed from the liquid substance, which in appearance and to the touch is similar to expanded polystyrene. Polyurethane is in great demand among builders.

The material is highly safe for the human body, it also instantly adheres to the surface and is evenly distributed, while filling any joints and cracks.In addition, polyurethane has a high service life and guarantees quality for decades.

Where is fire resistant thermal insulation used?

Despite the fact that most of the high-temperature insulation is used for one purpose, their area of ​​application varies. So some can be used in the construction of large buildings and industrial facilities, while others are only suitable for insulating a bath or pipes.

Basalt wool is the most widespread. Most often it is used for thermal insulation of external facades. The great advantage is that it can be used both for exterior and interior decoration. Because the material has all the necessary technical characteristics for this.

Mineral wool is also in great demand for summer cottages, but it has slightly worse technical characteristics that do not allow it to be used with any insulation. But unlike the previous version, it has greater elasticity, which allows it to be installed in complex shapes.

Some people buy fireproof thermal insulation for insulating non-residential premises or attics. Here experts recommend using bulk materials, they are more suitable for this.

To produce high-temperature insulation in places with high humidity, it is necessary to select a moisture-resistant and vapor barrier insulation. It will be best if this product is stone wool.

Basalt wool is used to insulate living rooms. But besides her, you can use roll form factor mineral wool for insulating floors or wooden structures.

What else you need to know

In order to achieve maximum thermal efficiency, it is necessary to buy insulation for any place, but to engage in complex thermal insulation of the entire room. So if a person insulates the floors, this is good, but the cold will still flow through the walls, even in a small amount, but it will be noticeable.

Cost is not the main criterion, but necessary. Of course, saving is good, and when a store sells two identical products, but at different prices, a product with a low price tag looks more attractive. Yes, at first glance, they have no differences, but it may be that in an expensive product they made a benchmark to increase all technical characteristics and used the latest developments in production.

When a person buys mineral insulation, attention must be paid to the placement of the fibers. The best product will be the one with random placement. Such models show high results in heat and sound insulation, in contrast to similar representatives, but with a vertical or horizontal arrangement.

When choosing a material for facade insulation, the product must not only withstand high temperatures, but also have low thermal conductivity and not lose its properties from moisture. For the interior decoration of living quarters, the main parameter will be safety and the absence of harmful toxic substances.

The only thing you can save on when choosing mineral wool is density. However, here it is necessary to take into account the place of operation. If the product is planned to be used where it will not be subjected to heavy loads, then the savings are quite appropriate, otherwise it does not make sense and it is better to take a durable model with high tensile and compression rates.
