Revenue model

1. Burnblock Fire-Retardant Powder (B2B): Sold to industrial partners (impregnation companies, timber manufacturers) who use the powder in their manufacturing/impregnation processes. Partners purchase the powder in IBCs/containers (ready-to-use water-based solution at standard 18.5%) or customized big bags for mixing tanks. Revenue is derived from product sales to the partner network across Europe and internationally.
2. Burnblock Liquid (B2C/Distributor): Sold exclusively through named distributors in each country (Thomsens Brandteknik in Denmark, OldenWood in Poland, Prodekor AB in Sweden). Available in 500ml spray bottles, 5L and 25L canisters for surface impregnation. End customers include hotels, schools, hospitals, theaters, and public facilities.
3. Technical Support & Certification Services: Burnblock provides extensive technical documentation, certification support (CE marking, AVCP 1/1+), and expert guidance through its Knowledge Center to help partners achieve fire classification for end products. This supports partner loyalty and recurring business relationships.

Core offering

Burnblock develops and manufactures a patented, naturally derived fire-retardant solution for wood and natural fiber products, sold in two formats: Burnblock Powder for industrial pressure impregnation (sold to impregnation partners in IBCs/big bags) and Burnblock Liquid for surface impregnation (sold through distributors in spray bottles and canisters). The company also operates a Pilot Plant facility near Copenhagen that provides custom material testing and certification support, helping partners achieve CE Mark and AVCP 1/1+ classification for fire-rated wood products.

Product overview

Burnblock® offers a portfolio of naturally derived, non-toxic fire-retardant solutions centered around two main product lines: Burnblock® Powder (for pressure impregnation of wood and natural fiber products) and Burnblock® Liquid (for surface impregnation). The company also operates a Pilot Plant facility for custom material testing and provides a Knowledge Center for partner support. The powder product uses a patented formula of purely natural ingredients that prevents oxygen from reaching treated objects, achieving fire classifications up to B-s1,d0. The liquid product is distributed exclusively through regional partners for surface applications. All products are 100% naturally derived, biodegradable, non-toxic, pH-neutral, non-corrosive, and VOC emission free.
