Intumescent Fire Stopping: First, the Science
Intumescent strips and smoke seals contain a substance which, when exposed to heat, swells to increase in volume but not in density. These intumescent substances are therefore very useful in providing a fire-proof smoke seal or barrier when the temperature rises as a result of a fire.
Intumescent Fire Stopping: Two Types for Two Jobs
Intumescents come in two main types:
- Soft char intumescents produce a light char (or ash), which is a very poor conductor of heat. They are often coupled with a hydrate, which releases water and therefore keeps the product cool. Once the hydrates have given off their water, the char produced continues to insulate against heat for a period of time. Fire pillows contain soft char intumescents
- Hard expanding intumescents are often mixed with graphite or sodium silicates to produce products that expand rapidly to fill spaces. The idea is that fire is prevented from traveling through gaps, holes or openings by the rapidly expanded intumescent products. Door seals use hard expanding intumescents
Intumescent Fire Door Seals: Automatic Protection That Buys You Time
Fire doors are highly effective in retaining fire for a period of time, but their weak point is their fit to the door. Fire will travel through any gap to the air beyond, so it is important that fire doors have an effective seal at all times.
Intumescent strips fit into a channel on the fire door or the frame (or surface mount), and when exposed to heat, expand to seal the door frame with a flame-tight seal for up to 60 minutes. That gives you (and the fire fighters) up to an hour of flame-free escape time, invaluable extra time for any premises.
Intumescent Fire Door Seals: No Smoke Seals
Our fire and smoke seals give you a smoke-free environment, thanks to the nylon pile that stops smoke from entering the door frame gap before the intumescent seal forms. For complete protection, our fire, smoke and draft seals offer the best protection possible, with a single or double rubber blade in place of the nylon. This give a better 'everyday' seal and these fire and smoke seals give that reassuring, air-tight 'whoosh' sound as you exit a fire door on a day to day basis!
All Fire Protection Online door seals are fully tested to British Standards and have LANTAC Building Control and NHBC approval.
Intumescent Mastic: No Gap Too Far?
Intumescent mastic behaves like ordinary mastic sealants, but with serious attitude! Use it to seal gaps around doors, windows, cables, pipes or indeed any small hole in any fire-rated building or structure. This mastic will fill gaps up to 25mm wide and gives everything it covers an impressive four hours of fire-resistant protection.
Fire Pillows: Never Caught Napping
Intumescent fire pillows are a remarkably flexible and versatile solution to providing a flame-proof seal in ducting or cable runs. When maintenance is required, simply move them away and replace when you're done. If a fire starts, these pillows will expand and form a flame-proof seal that stops fire spreading through a structure via is ducting or conduit systems. All four sizes of fire pillow from Fire Protection Online have EN1366-3, LANTAC Building Control Approval and NHBC Type Approval.
Whether it intumescent strips or smoke seals, there is a product for stopping every type of fire.
