Examples of use:

With tall office buildings like The Shard, Maxim Office Park and Heron Tower becoming more popular in the non-residential market, quick and easy fire protection applications help these structures maintain their load bearing capacity during evacuations.

The cost advantages of steel-framed construction mean more schools, hospitals and council buildings are being built in this way, with multiple floors that have to be covered by fire sprinklers as well as fire protection coatings and systems.



Approximately 8 - 10m² per litre per coat. Two coats required.
