Impact and airborne sound insulation
Granab subfloor systems are installed in many office projects. Flexible line routing between subfloors and floor coverings entails major benefits, while the Granab system also creates a good acoustic environment. Granab systems fulfil the acoustic requirements for offices in accordance with SS 25268 by a very wide margin.
Pleasant, comfort-adapted floors for a better working environment
In a good working environment, it is important that floors are not hard or rigid as this can lead to pain in the shoulders, back and legs. Granab systems, with their integrated impact-dampening effect, provide comfortable floors with a documented degree of deflection for point loads.
Example – planning electrical, datacom, telecom – offices
System description – electrical.
Granab subfloor systems permit the distribution of supply systems for power, telecom, datacom, etc. Premises larger than 1000–2000 m2 are divided into supply zones.
Spaces – central units.
The supply zone is equipped with a fixed unit (a so-called island with toilets etc.) where central units for power, telecom, datacom, fire alarms etc. are placed.
Canalisation – line routes.
The cable networks are run on cable trays or baskets under the floor along a primary route from the central units and on to the supply zone. The floor is equipped with access hatches over the route. From the primary route, the cables are run in installation conduits to the equipment locations (outlets). The system can be potential-equalised.

To ensure that planned sound classes are attained both vertically (between floors) and horizontally (on the same floor) in completed buildings, all components of the building construction must function in the correct manner. An acoustic consultant should be engaged to review planned building constructions (construction documents). During the construction phase, installation should be checked according to our checklists.
