The Story of Sisalwool
It includes Scottish sheep, fishing boats and coffee sacks.
It's a good one.
Sisalwool Silent 100 Acoustic
Sisalwool Silent is a high-performance, natural acoustic insulation made from breathable plant and wool fibres. It delivers a Class A sound absorption rating and immediate results, all with an effortless friction-fit installation.
Sisalwool Silent's density enhances the acoustic benefits of our slabs compared to others on the market, yet it's still breathable thanks to its natural fibre composition, making it suitable to provide ultimate sound insulation ideal to use in stud walls between bedrooms, in office spaces or a home office - with or without the addition of plasterboard!
Each batch is made with fibres such as recycled coffee sacks and off-cuts from the clothing and carpet industries; all materials that would otherwise end up in a landfill.

FAQ
Sisal fibres have a naturally breathable structure that allows vapour to pass through, helping regulate indoor humidity and reduce the risk of condensation or mould. Combined with wool’s ability to absorb and release up to 30% of its weight in moisture without feeling damp, Sisalwool insulation helps maintain healthy indoor environments – ideal for traditional buildings that need vapour openness and long-term stability.
Sisalwool has been tested to Euroclass E for reaction to fire, meaning it self-extinguishes when exposed to a small flame and does not melt, drip or emit toxic fumes. This rating makes it suitable for use on non-boundary walls in homes up to 11 metres in England and up to 18 metres in Scotland.
However, fire safety depends on more than just the insulation. In real buildings, materials like fire-rated plasterboard provide additional protection, and the full wall build-up matters.
Natural insulation will not achieve the highest fire ratings (such as A or A1), as those require synthetic layers like foil, which can release harmful gases when burned.
Sisalwool includes a fire-retardant treatment as standard and is a safe, low-toxicity option for most residential builds. For high-rise or higher-risk buildings, other materials may be more appropriate depending on local regulations. Always check with a qualified professional for your specific project.
Yes - We use a long-lasting insect deterrent treatment to moth proof our wool. The treatment works as an insect resistance agent by making the wool protein unpalatable to the wool moth larvae.
Our wool comes from a variety of avenues, making each blend unique in its own way (while the insulation properties stay the same).
“Sisalwool is easy to cut, fast to install and safe to work. It’s bloody brilliant! Also, there was basically no waste as off-cuts could be used elsewhere unlike PIR.”
