Why Cavity Fire Protection UK from GRJ?
With over 15 years of experience in the construction industry, GRJ Contracting instals cavity fire protection across the UK, achieving long-lasting results.

This type of passive fire protection works by sealing off any gaps in your building's cavity. The materials used in fire barriers are sensitive to high temperatures, which means they expand when exposed to heat.
Here at GRJ, we work with a selected list of suppliers that provide only the most reliable building materials. This is why you can have complete trust in our fire barrier services.
