Lamella Mat
Up to 750°C
Main applications
a lamella-oriented mat that distributes compressive load
Key Features
Vertical (lamella) fiber orientation
Fibers oriented vertically — distributing compressive load along the fiber direction for outstanding compressive strength in external wall systems
Excellent sound absorption and blocking
Mineral wool based — a high absorption coefficient meeting the acoustic requirements of external wall insulation
Non-combustible, 750°C
Inorganic rock wool — non-combustible grade, preventing fire spread through external insulation
Optimised for EIFS
A lamella mat made for external insulation finish systems — improving render adhesion and durability
Excellent moisture and water resistance
The water resistance of rock wool keeps insulation performance stable through rain and dew exposure

Applications
External insulation finish systems (EIFS)
- •Board for external rendered insulation systems
- •Non-combustible board replacing EPS
Fire-rated external insulation
- •Buildings requiring semi-non-combustible or non-combustible external insulation
- •Fire prevention in high-rise external insulation
Curtain wall & facade insulation
- •Infill insulation between curtain wall units
- •Insulation behind metal facade panels
Industrial plant insulation
- •Insulation mats under compressive load on plant
- •External insulation of tanks and equipment
Notes
- ※The lamella structure gives two to three times the compressive strength of ordinary mineral wool board — the key material in EIFS.
- ※Installing glass cloth mesh alongside the render maximises crack prevention.
