Fireproofing intumescent wraps
The AF SLEEVES are flexible intumescent wraps designed to protect plastic pipes that pass through walls and floors. The AF SLEEVES contain intumescent stripes which under the action of heat, expand until the complete obstruction of the opening.
When exposed to fire, AF SLEEVES’ internal material rapidly increases its volume and fills the space left by the collapse of the pipes. The expansion of the AF SLEEVES blocks the passage of smoke and flames. The AF SLEEVES guarantee the EI 120/ EI 180 resistance to fire (in accordance with the European Standard EN 1366-3).
