A Scottish company looking to revolutionise the way buildings are insulated has secured an £800,000 investment to increase manufacturing capacity and explore new market opportunities.

Sisaltech’s growth will also deliver a boost to supply chains, including Scottish sheep wool and help develop the circular economy.

The funding round was led by Tricapital Angels, with backing from Scottish Enterprise.

The Midlothian-based company uses natural and recycled fibres to create innovative low-carbon insulation products that are highly breathable and well-suited to retro-fitting traditional stone buildings.

Its Sisalwool products – which are already stocked by B&Q – can be used in a wide variety of applications including pitched roofs, wall, and under suspended timber floors.

Moray Martin, chief executive of Tricapital Angels, said: “Sisaltech is a forward-thinking, innovative and impactful business, exactly the type of company we are geared up to accelerate as they scale and transform the construction sector with products that perform exceptionally while tackling the climate emergency.”
