Yes - We use a long-lasting, biodegradable 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.

Sisalwool successfully passed the Euro-class E (Reaction to Fire) surface spread of flame test, a classification. making it fully approved for use on non-boundary walls in buildings up to 18 meters high. In this test, a direct flame, like a lighter, is applied to the material. Once the flame was removed, Sisalwool self-extinguished, demonstrating its fire-resistant properties.

But in true Sisalwool fashion, we didn’t stop there. We went one step further. To prove just how robust Sisalwool is, we thought why not do the test again, but this time with a blow torch? The results speak for themselves.

Fire ratings are extremely important, and equally complex. We’ve untangled the nuances and broken down the key points here.

Yes, Sisalwool is ideal for acoustic insulation! Our 100 mm slabs have a Class A certification, meaning they typically absorb 90-100% of sound energy.

Our 50mm slab carries a Class B certification indicating it effectively reduces noise levels, echoes and reverberation within a space.
