General information

The recycled woollen fibres blankets are made from second hand clothes various fibres. New fibres may be included as well. Recycled wool is cheaper than virgin wool, and is appropriate to all types of climates, under the condition that our minimum specifications are met, and good manufacturing practices are respected.

The insulation capacity of a blanket depends of the thermal resistance (Rct) and of the air permeability of the material. The thermal resistance does not depend only on the weight or the raw material, but also on the fibre quality, the type of weaving or knitting, and fibre raising.

  • Low Thermal type, with Rct=0.15m².K/W is appropriate for indoor use, on a bed, in a house with heating facilities.
  • Medium thermal type, with Rct=0.25 m².K/W, is the minimum for hot or temperate climates outdoor use (even in hot countries, nights can be cold).
  • High thermal type, with Rct=0.4 m².K/W, is appropriate for cold climates.

Scientific studies defined that indoors at 20°C a person at rest requires a total insulation of Rct=0.15 m².K/W. Outdoors with no wind the value at 10°C is Rct=0.4 m².K/W, at 0°C it is Rct=0.6 m².K/W, at -10°C it is Rct=0.8 m².K/W and at -20°C it is Rct=0.95 m².K/W. Bearing in mind that a part of the insulation comes from the clothing, the rest will come from the blanket.

  • The Rct value can only be tested in a textile laboratory.
  • Low air permeability ensures protection from draughts, while inherent breathability allows evacuation of body perspiration.
  • In previous publications, the Thermal Resistance was given as ToG (Thermal Resistance of Garment). It is important to note that ToG=1 is identical with Rct=0.1 m².K/W. The major difference is the laboratory equipment to control these values. The Rct test is more accurate than the ToG test.

Other colours than the standard are available at higher costs and longer lead-time.

Blankets are subject to International Purchase Frame Agreements with validated manufacturers. Please refer to your HQ before purchasing.

Packing

- Bales to be wrapped in a water-tight micro perforated plastic film and covered with a polypropylene or jute woven bag.

- Quantity per bale: 20 pieces.

- Compressed and strapped with 5 straps (2 lengthwise, 3 crosswise).

- Bales dimensions: Length approx. 0.8m, width approx. 0.5m

- Height of the bales to be compressed by maximum 40% from free state to final compressed and strapped state.
