The line
What Is the ECO-BUILDING Line?
ECO-BUILDING is the Casei Eco-System product line dedicated to applications of recycled rubber in the construction industry, with a particular focus on sound insulation, acoustic decoupling, and surface protection.
These products serve different purposes: ECO-FON ROLL is a continuous solution available in rolls; ECO-FON STRIP is used at the base of walls; ECO-FON MAT is designed for the support points of adjustable brackets; ECO-FON CORK combines recycled rubber and natural cork; ECO-ROOF is designed for the exterior surfaces of flat roofs and terraces.
Applications
Where ECO-BUILDING Solutions Are Used
The various models in the product line allow for installation in multiple locations within the building. The most suitable solution depends on the construction system, the required function, and the configuration specified in the design.

Floors, Screeds, and Floor Slabs
ECO-FON ROLL is the solution to consider for systems that require a continuous resilient layer. ECO-FON CORK is worth considering for configurations that include insulation made from recycled rubber and cork.

Walls and Partitions
ECO-FON STRIP is installed at the base of vertical partitions to create a decoupling element from the installation surface. The width and thickness should be selected based on the intended configuration.

Raised Floors and Exterior Surfaces
ECO-FON MAT is used under the adjustable supports of raised floors, while ECO-ROOF is designed for flat roofs and terraces where a walkable surface with drainage capabilities is required.

Frequently asked questions
Frequently Asked Questions About ECO-BUILDING
Which product should you choose for sound insulation under a floor?
ECO-FON ROLL is one of the options worth considering when the system requires a continuous resilient layer made of recycled rubber. ECO-FON CORK should be considered when the design calls for a solution that combines recycled rubber and cork. Thickness and layer configuration must be verified based on the actual project.
What is ECO-FON STRIP used for?
ECO-FON STRIP is a recycled rubber strip designed to decouple vertical partitions from the installation surface. It is used at the base of walls and partitions to help control the transmission of vibrations.
What is the difference between ECO-FON ROLL and ECO-FON CORK?
Both are acoustic insulation materials supplied in rolls. ECO-FON ROLL is made of recycled rubber, while ECO-FON CORK combines recycled SBR rubber and natural cork. The choice depends on the application, the layering, and the project requirements.
Where is ECO-FON MAT used?
ECO-FON MAT is placed between the base of the adjustable supports for raised floors and the subfloor. It creates a localized protective layer and helps reduce impact noise.
Does ECO-FON MAT come in standard sizes?
The dimensions are determined based on the geometry of the support base. The product is then custom-made. Thicknesses range from 2.2 to 10 mm.
Is ECO-ROOF a soundproofing membrane?
No. ECO-ROOF serves a different purpose than ECO-FON insulation: it is a flooring system made of recycled rubber tiles designed for use on flat roofs and terraces.
Can I request the technical documentation before finalizing the order?
Yes. To make your request more specific, it is helpful to indicate the product or application, the planned construction system, any sizes or thicknesses you have already identified, approximate quantities, and the necessary documentation.
