Loose Wool (Insulation Fill)
Up to 700°C
Main applications
loose wool that insulates any space completely
Key Features
Bulk fill that goes anywhere
Loose wool in bulk form — blown or packed into tight spaces and cavities that board and roll cannot reach
Optimised for blown installation
Blown into existing structures — maximising insulation without demolishing internal walls, excellent for retrofit
Acoustic and thermal performance together
Bulk fiber absorbs sound while insulating — blocking building noise and saving energy
Non-combustible inorganic material
Rock wool or glass fiber based — non-combustible grade, safe in fire
Economical over large areas
Bulk installation over large areas cuts labour cost compared with board, resolving complex geometry economically
Specifications

Applications
Retrofit blown insulation
- •Blown insulation inside existing walls
- •Filling the void in twin roofs
Structural insulation
- •Filling insulation between studs
- •Insulating raised floor voids
Filling tight spaces
- •Filling gaps around pipes and ducts
- •Topping up damaged existing insulation
Acoustics
- •Blown acoustic absorption in walls
- •Acoustic fill in ceiling voids
Notes
- ※Blown installation requires a dedicated blower — large-area work is best handled by a specialist contractor.
- ※Fill density directly determines insulation performance — the recommended density must be observed.
