FiberTherm Isorel wood fiber panel is a multi-purpose rigid insulator for walls, floors and roofs, ideal for completely natural insulation with reduced thickness.

With wood fiber FiberTherm Isorel you can completely insulate your building in a completely natural way and with reduced thickness, guaranteeing the realization of environments with a high living comfort as well as a really healthy internal atmosphere.
The FiberTherm isorel panel is produced with a wet system, the only one to guarantee the complete compatibility of the material with the criteria of green building, because it is free from any type of toxic substance. It has density equal to 230 kg/m³.

The material is also recyclable, with relative NaturePlus certification and made exclusively with wood from controlled forests in compliance with the FSC directives.

The FiberTherm Isorel wood fiber panel is an excellent thermo-acoustic insulation for flat roofs, walls and floors:

• subflooring;
• adequate protection against atmospheric agents;
• high compression strenght;
• very good thermal insulation in winter and summer;
• contributes to maintaining a mild indoor climate;
• climate control with high absorption capacity;
• recyclable, ecological, respects the environment;
• tested and authorized building material based on current European standards.


The FiberTherm Isorel wood fiber panel is suitable for any type of thermal and acoustic insulation that requires reduced thickness and high compressive strength.
In particular this material can be used for the realization of:
• substrates for floors with subflooring;
• external insulation of roofs and ceilings;
• under-tile insulation, with adequate insulation protection;
• insulation of walls in dry systems;
• cavity insulation with dry system;
• internal insulation of the walls.


The installation is closely linked to the type of use of the panel according to which it will be appropriate to adopt the most suitable application method. In general it is always necessary to protect this material from humidity both before laying, during the storage phase on site, and in the phases prior to the realization of the coating. If the material is exposed to water, let the material dry.
