Why this product
This is not just another insulation material —
it is a solution that also delivers:
Thermal comfort
Good acoustics
A healthy indoor environment
Unlike synthetic materials, it:
“Breathes”
Regulates moisture
Creates a more pleasant indoor feel
Technical description
Thermal and acoustic insulation slabs made of hemp fibres (approx. 66%) and jute (approx. 22%) combined with polymer support fibres.
The fibrous structure provides:
Trapped air → thermal insulation
Sound wave absorption → improved acoustics
Moisture regulation → a stable indoor environment
According to the manufacturer’s data:
The product has a low thermal conductivity of approx. 0.040 W/(m·K), providing effective thermal insulation
In addition:
High heat capacity → maintains a stable temperature
Low vapour diffusion resistance → lets the wall “breathe”
Applications
- Plasterboard walls
- Exterior and interior walls
- Ceilings
- Roofs (between rafters)
- Interior partitions
- Timber and frame structures
- Renovation and green building
Technical specifications (for 5 cm thickness)
- Type: natural insulation slab
- Thickness: 50 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
- Tensile strength: ≥ 30 kPa
Data according to the technical data sheet
Acoustic performance
Good sound absorption in lightweight construction
Better reverberation control in rooms
Suitable for use in plasterboard walls
According to the data:
At 40 mm thickness, αw ≈ 0.7 (Class C, EN ISO 11654)
At greater thicknesses, it reaches Class A
In other words – performance improves significantly as thickness increases
Installation
Cuts easily with an insulation knife
Installs between framing members
Can be slightly compressed for a snug fit
Gap-free installation is recommended
Manufacturer’s recommendation:
Install with a slight “press fit” to prevent gaps
What makes it unique
This is a product with a story to tell:
- Completely natural
- Breathable
