Flame Retardants for Insulation

Natural fibre-based insulation has increased its attractiveness as a multipurpose building material suitable for a range of purposes. Natural fibre-based insulation boards and acoustic panels can be made more competitive and attractive in several segments by improving its flame retardancy.

You can enhance the fire properties and fire-resistance rating of natural fibre-based insulation by treating it with Kiilto’s I-series Fireproof flame retardant. Kiilto Fireproof flame retardants are mostly bio-based* and do not affect the appearance of materials it is used with.

Treating insulation materials with Kiilto Fireproof flame retardants can improve its fire properties and fire-resistance rating. Fireproofed insulation is mainly used inside walls or as a final surface, such as acoustic boards. Treatment with Kiilto flame retardants can enable up to EN 13501-1 Class B fire performance

Various treatment options

Kiilto Fireproof I-series flame retardants are single-component, water-soluble, pH-neutral and industrially applicable products for natural insulation materials. Their flame retardant properties are tailored to meet the customer’s production process and requirements. Possible treatment methods include:

  • spray
  • impregnation

Each production line is unique. The insulation type and application method also have a major effect on how the material should be treated. Alongside the customer, Kiilto’s flame retardant team plans and implements the most suitable flame retardant treatment.
