Gumthorn specialises in A1 fire rating protection using specialised coating applied to surfaces such as concrete.  The coatings provide passive fire protection.

Key Characteristics of A1-Rated Materials

• They pass the strictest tests for non-combustibility.
• They do not ignite, sustain burning, or add to the fire load.
• No additional smoke or droplet sub-ratings are needed, unlike lower classes.
• They are ideal for high-risk areas such as high-rise buildings, hospitals, schools, escape routes, firewalls, and façades where maximum fire safety is required.
