Rockwool Flexi Flexi
Rockwool Flexi acoustic slab is the rockstar insulation for any framed construction. Fresh timber, shrunken timber, uneven metal frames, this slab adapts perfectly to all. Best of all, it provides both thermal and acoustic insulation.
What is Rockwool Flexi slab?
As its name implies, Rockwool Flexi slab has a flexible edge along one side. This clever innovation makes it a natural choice for friction-fit installations. The slab fits snugly, even when used with a frame that has uneven edges or one where the material has shrunk.
What is Rockwool Flexi insulation used for?
Rockwool Flexi insulation slab is highly versatile. You can use it for:
- Internal partitions in areas such as hallways, living rooms and bathrooms.
- Ceilings and suspended floors.
- Pitched roof rafters.
- Loft conversions.
- Framed external walls.
- Separating walls and floors.
- Metal and timber stud walls.
The flexible edge does the magic in places where the frame is uneven, in that it conforms to fit snugly within the frame. You may face a similar challenge when working with shrunken timber, but the flexibility of the slab’s edge ensures you get a tight fit.
Benefits of Rockwool Flexi slabs
Rockwool Flexi slabs offer the following benefits:
- Perfect friction fit installations: The slab’s flexible edge fits into most timber and metal frame spacing.
- Simple installation: In most applications, cutting isn’t necessary. Just squeeze the flexible side into the space where you need it and the rest will fit.
- Dimensional stability: Rockwool Flexi does not slump, shrink, move or lose density. Once installed, it retains its shape, size and performance throughout the building’s lifetime.
- Excellent thermal and acoustic protection: Flexi offers consistent thermal insulation and effectively blocks sounds between rooms. So you can use it to contain noise within a room or keep sounds away.
- Enhanced fire safety: The noncombustible Rockwool Flexi slab is classified Euroclass A1 under EN 13501-1. It can withstand temperatures over 1000℃ and won’t contribute to fire spread.
- Environmentally friendly: Rockwool Flexi insulation is a fully recyclable product.

FAQ
What is Rockwool Flexi?
Flexi is a semi-rigid stone wool slab from Rockwool, designed to offer flexible insulation. It’s best suited for framed systems in walls, floors and roofs. Rockwool Flexi slab acoustic insulation provides both acoustic and thermal insulation. Since it’s made from noncombustible materials, it also boosts fire protection in buildings.
How to install Rockwool Flexi slabs?
In most cases, you can fix Flexi insulation without resizing. Simply push the slab into the framed space and then release it. You can bend the flexible side to fit it into a space if the slab is slightly bigger. In slightly wider spaces, the slab expands to fill the space.
To cut a Flexi slab that’s too big, use a knife with a long blade or an insulation knife. Remember to wear protective gloves and a mask to prevent irritation.
Flexi slabs are ideal for friction-fit systems and don’t require mechanical fasteners. But if you must use some, refer to Rockwool’s recommendations for the best fasteners for the application.
