Rockin Bag System from ROCKWOOL is a thermal insulation system by blowing in rock wool for converted or convertible attic slopes composed of nodulated rock wool (Rockin L), the Rockbag bag and adhesive which allows the end to be closed bags and insufflation holes.
The technique consists of blowing, using an electric machine, loose rock wool into the Rockbag bags. Insufflation is carried out from the outside after partially stripping the tiles into horizontal lines. Highly efficient, Rockin L rock wool for insufflation guarantees excellent thermal performance with a thermal conductivity of 0,036 W/mK and offers on average 3°C more thermal comfort, i.e. 20% energy savings observed after installation.
