How it works

How does Burnblock® work?

Burnblock is a highly effective and non-toxic fire retardant. Burnblock consists of purely natural ingredients combined in a patented formula. Burnblock effectively prevents oxygen from reaching the treated object – and without oxygen: no fire.

Burnblock is completely harmless and even in case the substance should make contact with the human eye, it will be no more harmful than fruit juice (ref. made to the health assessment).

Burnblock is a highly effective and well documented fire retardant, that can be used both industrially and as a post treatment. It is an invisible treatment, that when applied correctly leaves no greasing, no staining, no trace, making the treated material ready for most post treatments, this weather the treated material being wood, paper, textiles ect.

Once absorbed by the treated material, Burnblock leaves behind a surface that can char and release water upon application of heat. This process absorbs a portion of the heat and helps prevent further occurrence and spread of fire.

Materials treated with Burnblock are, therefore, protected from combustion and any spread of flame.

Burnblock® impregnation process

Have you ever wondered what the process of impregnating wood with Burnblock® looks like? You don’t have to any more, after watching this video everything will become clear.

Burnblock meets regulatory requirements

Burnblock has tested and classified a long list of wood species to the highest possible standard; EN13501-1:2007 (reaction to fire), EN14135 (resistance to fire) EN45545:2015 R1&R10 (rolling stock).


Burnblock does not induce corrosion.

Economical in use

Burnblock is very economical in use and accordingly, our price per weight unit ratio will outperform most competing products. In addition, there are many other aspects which will contribute significantly to improving your bottom line:

  • Easy handling procedures will be cutting costs.
  • No heating is required when mixing Burnblock
  • Burnblock is non-toxic and biodegradable, hence waste disposal concerns and costs will be reduced.

What health risks does Burnblock represent?

Burnblock requires no specific safety equipment, however some data indicate a slight irritation if Burnblock should accidentally come into direct contact with the eye. The Danish Technological Institute assesses this effect to be less than that of natural lemons and fruit juice.

In the Health Assessment from the Danish Technological Institute, no significant health risks due to Burnblock components are listed.

Is Burnblock easy to handle and apply?

Yes. We have made the application process as easy as possible for you:

For industrial solutions Burnblock is supplied to our partners in IBCs/containers in a ready to use water based solution (standard 18.5%) or supplied in customized big bags to fit your mixing tank: add water; stir shortly; and Burnblock is ready to use. Heating is not required.

Burnblock is also available in 500ml bottles with spray, 5L and 25L canisters.

Can I store Burnblock?

Yes. Burnblock is a highly stable solution and can be readily stored at ambient temperatures, avoiding solution freezing. It is recommended to avoid prolonged exposure to direct sun light.

We are an enterprising company, characterised at heart by a pioneering spirit and the courage to follow new paths.
