Acoustic Flooring in Gothenburg

In central Gothenburg, SubFloor acoustic flooring is being installed in apartments on the top floor.

An uneven, old concrete floor is leveled using SubFloor in a quick and easy manner by the construction contractor Göteborg Byggstart AB.

For this project, a combination of SubFloor’s 11-mm steel joists, SubFloor’s 45x45-mm wooden joists, and 100-mm plastic screws was chosen due to varying floor heights.

To meet the high acoustic requirements, SubFloor's 12-mm acoustic underlay was chosen.

With this design choice, the construction height ranges from 38 mm to 127 mm to the top edge of the joist.

Design

• 12.5 mm floor drywall, screwed—not glued—to the particleboard
• 22 mm particleboard, screwed and glued to the joists
• 11 mm steel stud and 45 mm wood stud, respectively
• 100-mm plastic screw
• Acoustic Foot 12
• 20 and 45 mm of insulation between the studs, respectively
• 160-mm concrete floor slab
• Total possible construction height from the joist floor to the top edge of the gypsum floorboard: 72–161 mm.
