Wool Bricks Introduction



Wool Bricks developed by Spanish and Scottish researchers with an aim to ‘obtain a composite that was more sustainable, non-toxic, using abundant local materials that would mechanically improve the bricks’ strength’, these wool bricks are exactly what the name suggests.By adding wool and a natural polymer found, the brick is 37% stronger than other bricks, and more resistant to the cold wet climate. They should be fire resistance and environmental friend.


“The objective was to produce bricks reinforced with wool and to obtain a composite that was more sustainable, non-toxic, using abundant local materials, and that would mechanically improve the bricks’ strength,”

The study, which has been recently published in the journal Construction and Building Materials, was the result of close collaboration between the British and Spanish universities. The clay-based soils were provided by brick manufacturers in Scotland, which was also the source of the wool, since the local textile industry cannot use everything it produces. “The aim was to produce a material suitable for adverse climatic conditions, such as the specific ones in the United Kingdom,” the authors explain.

The researchers studied the effect of reinforcing various soil types with sheep’s wool, and arrived at various conclusions. “These fibres improve the strength of compressed bricks, reduce the formation of fissures and deformities as a result of contraction, reduce drying time and increase the bricks’ resistance to flexion.”

This piece of research is one of the initiatives involved in efforts to promote sustainable development of building materials increasingly And can manufacture these types of bricks without shooting, which contributes to energy saving. According to the book: “This is an alternative to a more sustainable and healthy to traditional building materials such as brick earth bread and concrete blocks.”

Untreated clay was one of the oldest building materials to be used by humans. The oldest examples of this can be found in houses in the Near East dating from between 11,000 and 12,000 years ago. Materials were found mixed with dirt and gravel plants to make them stronger also in some of the archaeological deposits 1400BCE in Sardinia (Italy).
