STEICO insulating materials: The multi-talents

Really quiet: because the right insulation can also provide sound insulation.

The unique combination of high raw density and the special fibre structure of the insulation boards make STEICO wood fibre insulating materials particularly effective in sound insulation.

Really smart: added value for your home

Protection against cold, heat and a healthy indoor climate bring tangible added value for the occupants of the house. But ecological insulation can also make a valuable contribution to increasing the value of your property. Because when it comes to a later sale, ecologically renovated houses are usually worth significantly more to buyers.

Really cool: high heat storage capacity in summer heat.

The particularly high volume weight of wood fibre insulation materials is a heat buffer that delays the passage of heat. Put simply: the heat remains trapped in STEICO wood fiber insulation materials until it gets cooler in the evenings.
