Where to use

Ceilings/Walls/Roofs/Floors:SheepWool Optimal is a high-performance natural insulation suitable for ceilings, walls, Roofs, and floors, offering excellent thermal and acoustic insulation. Its natural wool fibres help regulate humidity by absorbing and releasing moisture without losing insulating properties, keeping spaces comfortable and reducing condensation risk. In walls, it adds thermal efficiency and soundproofing, while in roofs and floors, it enhances energy efficiency and reduces noise transfer. SheepWool Optimal is sustainable, breathable, and naturally fire-resistant, providing a safe, durable, and eco-friendly insulation option that also improves indoor air quality.

Frequently asked questions

Is SheepWool Optimal easy to install?

Yes, it is user-friendly and easy to handle. It can be cut to fit snugly in various spaces, including between joists and wall studs, using standard tools. Its flexible and dense texture makes it easy to adjust during installation.

How does SheepWool Optimal improve indoor air quality?

Wool naturally absorbs indoor pollutants like formaldehyde, sulfur dioxide, and nitrogen oxides, improving air quality. It is also free from synthetic chemicals, making it safe and non-toxic for sensitive environments.

How does SheepWool Optimal help with moisture regulation?

Wool fibres naturally absorb excess moisture and release it when humidity levels drop, helping to control indoor humidity, reduce condensation, and prevent mould growth. This keeps the insulation dry and efficient.
