The construction industry is looking for non-toxic thermal insulation materials that can provide the most favorable indoor climate. Natural non-woven linen insulation with high performance characteristics has excellent prospects for use in environmentally friendly construction of residential buildings as an alternative to chemical thermal insulators.
Pros and cons of linen insulation
Flax is a natural antiseptic. This crop is grown without the use of pesticides. The thermal insulation material creates an environment that is destructive for bacteria, fungi and spores, and repels rodents. Flax is able to weaken the effect of a chemically harmful environment, reduce the level of electromagnetic radiation and radiation. Does not require special disposal.
Thermal insulation based on linen fibers:
- conserves heat no worse than fiberglass or mineral wool, excludes the formation of cold bridges;
- has high soundproofing characteristics;
- does not rot, does not grow moldy;
- helps to maintain a stable temperature inside the building, provides an adequate level of protection in winter cold, reduces the need for cooling and air conditioning in summer heat;
- does not dust, does not crumble, does not emit harmful substances and unpleasant odors, on the contrary, it functions as a filter, cleans the air in the room, absorbs odors;
- does not cause allergies;
- due to its high vapor permeability, it protects surfaces from condensation.
The main disadvantage of linen insulation is its high flammability. Therefore, the material undergoes a special treatment to protect it from fire. The next negative point is water permeability. Linseed fiber absorbs water well. However, it dries quickly and takes on the same shape without losing its heat and sound insulation properties.
When used in places with high humidity, linen insulation needs waterproofing. Thermal insulation structures must be well ventilated.
Release form
Linen insulation in the form of slabs and rolls is produced by the thermal bonding method - bonding natural fibers at high temperatures and processing for fire resistance. Plates are used for thermal and sound insulation of wall, ceiling and roof structures. Dense and homogeneous linen tapes - for insulation of inter-row joints and gaps between logs.
Linen insulation is also produced in the form of felt - by weaving fibers; batting - needle-punched method, linen fiber is quilted with nylon threads; tape tow - by combing the fiber.
Specifications and scope
The thermal conductivity coefficient of linen heaters on the insulating materials market is from 0.036 to 0.042 W / m * K. Sound absorption coefficient - 0.98. Density - 20-35 kg / m3.
The thickness of the linen slab is 50/100 mm, the length is 1000-1200 mm, and the width is 600 mm. The thickness of the insulation roll is 5 cm. The flammability group of popular linen materials is G 3. The service life guaranteed by the manufacturers is 60-70 years.
Flax-based insulation is used as a heat and sound insulation coating for horizontal, vertical and inclined surfaces - walls, partitions, ceilings, ventilated pitched roofs - in low-rise building structures. Ideal for internal and external insulation of houses from a bar, logs, frame buildings.
With the help of roll material, tape batting or linen tow, it is possible to bury the joints between the joints, cracks and cracks, it is easy to insulate the window and doorway. Thermal insulation based on natural fiber is recommended for use in residential buildings, in children's and medical institutions.
Popular brands
Premium class thermal insulation materials are in high demand:
- Ecoteplin;
- Termolen;
- Ecoterm;
- Ecolin.
All of them are environmentally friendly, do not contain phenol-formaldehyde compounds, do not emit harmful substances. They have a high degree of thermal protection, regulate temperature and humidity, create coziness and comfort in residential buildings.
Ecoteplin
Flax insulation Ecoteplin is produced by the Russian insulating materials plant Termodom. The technology of the German company Flaxhaus is used. Thermal insulation linen mats 50 and 100 mm thick with foil backing do not contain chemical composites. The binder is starch. Plates are not subject to shrinkage and deformation. Insulation does not need vapor barrier. Thermal conductivity 0.038 - 0.04W / m * K.
100% natural Ecoteplin is not without its drawbacks. This is a low fire resistance and a relatively high price. Borax is used for fire protection. The financial costs will be justified over time, since there will be no need to use heating electrical appliances.
Termolen
Linen mezhventsovye and wall heaters Termolen (roll and slabs) are produced by the Russian Flax-Jute Company. A low-melting bicomponent fiber (sintepon) is used as a binder, which increases the elasticity, durability and volume of the material. The unique fiber placement technology provides additional elasticity, creating a spring effect.
Plates with a thickness of 50 mm are produced using thermal bonding technology. Thermal conductivity: 0.036-0042 W / m * K. Natural linen insulation provides a high level of heat protection and noise absorption, creates a healthy climate in a wooden house. A roll tape with a uniform shape and density provides a minimum thickness of the insulation layer.
Ecoterm
Thermal insulation Ecoterm is produced in the Republic of Belarus. It is produced in the form of linen slabs with a thickness of 50 and 100 mm. As a binder, the manufacturer uses environmentally friendly polyester fiber, which gives the natural material elasticity, high density, resistance to deformation and shrinkage. Due to the vertical and horizontal arrangement of flax fibers, Ecoterm does not cake and retains its shape for a long time.
Thermoplates Ecoterm are designed for thermal and sound insulation inside living quarters. They are mounted without additional fasteners. Thermal conductivity: 0.038-0.04 W / m * K.
Ecolin
The Smolensk company Ekolen produces linen wool insulation (needle-punched technology) without the use of composites. The perfectly flat surface of linen batting makes it possible to eliminate the need for internal wall cladding in wooden houses.
Linen insulating material provides a convenient installation. You can work with it without protective gloves. Does not irritate skin, eyes and respiratory tract. Has a Russian certificate of conformity to those. regulations, meets the requirements of fire safety and sanitary and hygienic standards. Recommended for low-rise buildings.
