For many years now, Rockwool has offered the possibility to easily calculate which Rc value a certain construction yields.

Both the calculation tool and the Rockwool specification service are powered by Utopis. Utopis has the ability to manage item data and not unimportant combinations thereof. After all, system thinking is very important in construction.
