Top 50 – suspended ceiling infill 50 mm

Rebond foam has been used in carpet underlay and technical layers for decades. Its recycled origin does not diminish its value. Instead, it gives the material another use that is well suited to its properties.

Rebond foam is made from recovered foam production offcuts in different colours, so each batch may look slightly different.

Colour does not affect the material’s load-bearing performance, acoustic properties or behaviour. Sorting the offcuts by colour would increase the price without improving performance. Once installed, rebond foam remains concealed beneath the floor, behind plasterboard or above a suspended ceiling.

When choosing a product, focus on its intended application, thickness and density—not its colour pattern.

Rebond foam is designed specifically for applications where the material needs to perform under sustained compression. Its high density and cohesive structure make it considerably more resistant to compaction than lightweight upholstery foams.

This is one reason why rebond foam has long been used as carpet underlay—a layer exposed to thousands of footsteps every day. When correctly specified, the underlay is designed to retain its function rather than collapse after only a few months beneath the floor.

Selecting the right product remains essential. Its thickness and density must be suited to the type of flooring, the construction and the expected loads.

If you can hear your neighbours, a television through the wall or footsteps from above, you need sound insulation. Its purpose is to reduce sound passing through a wall, floor or ceiling.

If, on the other hand, your voice reflects around the room, conversations are difficult to understand and the space sounds echoey, the problem is reverberation. In that case, you need materials that absorb sound within the room.

Lightweight pyramid-shaped acoustic foams can help reduce echo and reverberation, but they cannot replace insulation within a building element. Kokon Pro works inside the floor, wall or ceiling assembly, as part of the barrier separating one space from another.
