Key advantages
- Exceptionally high thermal insulation
- Improved sound absorption compared with thinner slabs
- Natural, eco-friendly material
- Natural moisture regulation (“breathable”)
- Suitable for green building
- Non-irritating to handle
- Long-term stability
Why this product
When you want real results —
thickness makes the difference.
At 10 cm thick, you get:
More substantial thermal insulation
A noticeable acoustic improvement
Stable temperatures over time
Especially suitable for exterior walls, roofs and spaces that demand high performance.
Technical product description
Insulation slabs made of hemp fibres (approx. 66%) and jute (approx. 22%), combined with reinforcing fibres in a thermal process.
The fibrous structure provides:
Trapped air → efficient thermal insulation
Sound-wave absorption → improved acoustics
Moisture regulation → prevention of condensation
📌 According to the manufacturer’s data:
A thermal conductivity of approx. 0.040 W/(m·K), together with a high heat capacity, helps maintain a stable temperature over time
In addition:
Low vapour diffusion resistance → a “breathable” wall
Resistance to mould and pests
Applications
- Exterior walls
- Interior plasterboard walls
- Roofs (between rafters)
- Ceilings
- Acoustic partitions
- Timber structures
- Green building and renovations
Technical specifications (10 cm thickness)
- Type: natural insulation slab
- Thickness: 100 mm
- Density: approx. 37 kg/m³
- Thermal conductivity: 0.040 W/(m·K)
- Specific heat capacity: 2300 J/(kg·K)
- Water absorption: ≤ 4.2 kg/m²
- Vapour diffusion resistance: μ = 1–2

Acoustic performance
Very high sound absorption
Significantly reduced reverberation
Suitable for spaces that require improved acoustics
According to the data:
At greater thicknesses, the product reaches Class A (high absorption)
In other words – this is no longer just insulation, it is genuine acoustic treatment as well
Installation
Easy cutting with an insulation knife
Installed between structural framing
Fitted with light pressure to prevent gaps
Complete, gap-free installation is recommended
Manufacturer’s recommendation:
Install slabs slightly larger than the opening to achieve a complete seal
Special features
At 10 cm thick, this is a “premium” product:
- High-level thermal insulation
- Significant acoustic improvement
- Natural, healthy material
- Suitable for high-quality projects
