SYMMETRY 640 Doubleface N° 600 (Leichtfried Interior Product)

Symmetry 640 is a double-face loden quality from extra-fine Australian Merino wool that is manufactured in a particularly complex process. In this process, a binder yarn, not visible from the outside, serves to connect the two sides of the greige fabric.

Whether as cushion, bed cover or curtain - thanks to its harmonic colour combinations such as various natural shades with wool white on the back side and its voluminous and simultaneously soft feel, this cloth turns living spaces into areas of calm comfort.

Benefits of SYMMETRY 640

  • Fire resistance
  • Acoustic advantages
  • Moisture absorption
  • Indoor air quality
  • Better sleep
  • Appearance retention
  • Easy care

Fire resistanceBenefits of woolfor interior

Merino wool is naturally flame resistant due to its high water content and chemical structure. It is less likely to burn (with a very high ignition temperature of 600°C) and produces less noxious fumes and toxic gases than most synthetic textiles or cotton, which makes it a much safer choice for interiors. Should wool burn it neither drips nor melts so it cannot stick to the skin like most man-made fibres, sparing burn victims from severe injuries.

With a LOI (Limiting Oxygen Index) of 25, wool has the highest LOI among the commonly used textiles. The LOI is used for ranking the flammability of materials by measuring the amount of oxygen needed to sustain combustion. The higher the value, the less flammable the material.

Acoustic advantagesBenefits of woolfor interior

Merino wool is one of the most effective acoustic building materials. It has long been used in passenger aircrafts, cinemas and offices because of its acoustic properties.

Especially our voluminous woollen interior fabrics with their felted surface enable sound waves to penetrate into the fabric and become dissipated. Wool thus helps eliminate unwanted sounds and focus on desired ones.

Moisture absorptionBenefits of woolfor interior

A further quality feature of Merino wool is its ability to absorb, store and release humidity in the atmosphere depending on the internal and external environment. Achieving optimal moisture conditions within a room is a key factor of comfort and wellbeing.

Wool acts as a buffer with respect to moisture absorption and thus helps maintain consistent humidity levels indoors. Merino wool can absorb up to one third of its own dry weight without feeling damp or clammy.

Indoor air qualityBenefits of woolfor interior

Polluted indoor air can lead to discomfort, reduced efficiency or even chronic insomnia. Air pollution can be caused by the use of air conditioning systems, evaporation from certain building materials and furniture or combustion processes.

Merino wool has the ability to absorb molecules from pollutants such as formaldehyde, nitrogen oxides and sulphur dioxide. Furthermore, wool does not re-emit these noxious gases. It is estimated that wool purifies indoor air for up to 30 years.

Better sleepBenefits of woolfor interior

Recent research studies have found that sleeping in or under wool leads to a better sleep. This natural fibre resource creates a microclimate that assists in regulating the temperature and humidity of the air around the body, thus providing a restful sleep. The average person perspires around one litre of fluid each night which synthetic fabrics are unable to absorb. Merino wool by contrast can absorb up to one third of its own dry weight.

At night, wool fibres absorb this perspiration and during the day, moisture is naturally released back into the atmosphere. The evaporation of moisture also means no breeding ground for allergy-causing moulds, bacteria and mites. Furthermore, it is scientifically proven that sleeping in or under wool significantly lowers the human heart rate and leads to a better recovery during this resting phase.

Appearance retentionBenefits of woolfor interior

The high resilience and pile structure of fine Australian Merino wool show excellent resistance to perpetual use. The natural and fine crimp allows Merino wool to bounce back to its natural shape and woollen interiors therefore maintain an ‘as new’ look for a longer period. A wool fibre can be bent thousands of times without breaking and has the power to recover. This is why wool products last for years.

Easy careBenefits of woolfor interior

Merino wool’s overall natural stain & soil resistance is significantly better than that of cotton or synthetic fibres. It has a natural protective layer that is bonded to the surface and can therefore not easily be removed. These overlapping scales are slow to absorb liquids and thus allow spills to be wiped off before permanent staining occurs.

Merino wool only generates very little static electricity and does not attract dirt or lint as most commonly used textile fibres. Further information can be found in our stain removal guide for interior fabrics.
