Rockwool Frontrock max-E is a dual density slab for ex- ternal wall systems with excellent thermal conductivity performance and high sound absorption. It can be used for rendering systems with all kind of finish coatings – light or heavy, thin or thicker. The advantage of Rockwool Frontrock max-E compared with lamella is, that the outside surface, which is visibly marked, is highly compressed. While su- pported with mechanical fixings, Rockwool Frontrock max- E can be suitable also for extremely heavy loads, such as appear to be various thicker coated rendering systems. Due to its excellent lambda value (0,036 W/mK), we achieve a 15% better U-value for the external wall, as if we were
using the same insulation thickness of the standard EPS or mineral wool lamella.
Rockwool Frontrock max-E is an excellent thermal insula- tor. It is not flamable when exposed to open flame and does not generate smoke nor burning droplets. It helps to prevent spread of fire. Rockwool Frontrock max-E has also very good acoustic properties and helps to reduce the noise transmission from outside into the dwelling units. It is water repellent through the whole section and at the same time diffusion open for the vapour transmission.
