Intumescent Kit For Euro & Oval Mortice Locks

Yes, intumescent strips are fire rated and come in various fire-resistance classes. The fire rating will depend on the type of strip and the application. Ratings typically range from 30 minutes to 2 hours of fire protection.  

Strips must be manufactured and tested in accordance with BS476 pt22 and BS EN 1634-1. 

Generally no, however there are some specialist strips that are designed to be painted over without compromising their effectiveness. However, it’s important to use the appropriate type of paint, as certain paints or coatings may affect the strip’s expansion properties during a fire. Always follow the manufacturer’s guidelines regarding painting.

If the strip is cracked, damaged, or deteriorating, it should be replaced. Additionally, if a fire has occurred or the seal has been disturbed, it’s crucial to inspect the strip for integrity. 

Strip is generally stopped at the hinge, and restarts after. However the hinge itself must be fitted with intumescent sheet / pads under the hinge. 

The same applies to lock keeps, where an intumescent kit should be fitted under the keep. 

Enhanced fire safety: They help to contain fires, preventing them from spreading rapidly. 

Smoke and gas protection: Intumescent strips can prevent smoke and harmful gases from leaking through gaps. 

Cost-effective: They are an affordable fire safety measure compared to installing full fire-resistant doors or windows. 

Easy installation: They can be retrofitted into existing doors and frames. 

Intumescent strips typically don’t require regular maintenance. However, they should be inspected periodically to ensure that they are intact and undamaged. If the strip is compromised (e.g., cracked, torn, or degraded), it should be replaced promptly to ensure continued fire protection.

Intumescent hinge pads are fire-resistant pads that should be fitted behind the hinge leaf on both door and frame side. The intumescent material will expand when exposed to heat to seal fire doors to their frames and prevent the spread of fire. 

Yes, legislation and fire safety regulations require the use of fire-rated doors with intumescent seals, including intumescent hinge pads. Pads ensure the door’s overall fire resistance, which is crucial in providing safe egress routes and preventing the rapid spread of fire.

Intumescent material expands and forms a dense char when heated or is exposed to fire, increasing its volume and decreasing in density. This expansion is called intumescence.

The primary purpose is to achieve the fire rating of fire doors. When hinges are fitted to fire doors, gaps form around the hinge area that could compromise the door’s ability to resist fire. Intumescent hinge pads seal these gaps, ensuring the door remains effective in preventing the spread of fire and smoke.

Intumescent hinge pads are used in fire-rated doors, such as those in commercial, industrial, or residential buildings where fire protection is a priority.  

Our Responsibility: Offer and guide customers through fire door ironmongery legislation and offer tested and accredited fit for purpose products

Your Responsibility: To fit appropriate tested and accredited ironmongery when fire doors are required

Joint Responsibility:  Communicate effectively to ensure correct specification, selection, fitting and maintenance of ironmongery fitted to fire doors. If your not sure, please ask us

“More importantly still, I think you need to examine why you are doing this. You should be doing this because it’s the right thing to do. Not because legislation make you do it.”

The intumescent material in the pad reacts to the heat of fire and expands to seal gaps between the door and frame, preventing the passage of flames, hot gases, and smoke. 

Yes, our intumescent hinge pads are fire-rated and come in various fire-resistance classes. The fire rating will depend on the type of strip and the application. Ratings typically range from 30 minutes to 2 hours of fire protection.  

Strips must be manufactured and tested in accordance with BS476 pt22 and BS EN 1634-1. 

The main advantage of intumescent hinge pads is that they are designed specifically for the hinge area of fire-rated doors. Traditional fire seals typically work on the perimeter of a door, but hinge pads address the unique fire risks posed by the hinge gap, ensuring a more comprehensive fire protection solution. 

Intumescent hinge pads should be stored in a cool, dry place and protected from damage. They do not require special handling, but care should be taken to avoid exposing them to extreme conditions like heat and moisture prior to installation. 

Intumescent material expands and forms a dense char when heated or exposed to fire, increasing its volume and decreasing in density. This expansion is called intumescence.

The intumescent material in the strip reacts to the heat of fire and expands to seal gaps between the door and frame, preventing the passage of flames, hot gases, and smoke.

Two types are available, with or without smoke seal. 

Smoke seal strips generally have a brush seal fitted that stop the spread of smoke before the heat of a fire builds sufficiently for the intumescent seal to expand.  

Intumescent strips are fire-resistant plastic strips with a centre of intumescent material that expands when exposed to heat to seal fire doors to their frames and prevent the spread of fire. 

Yes, nearly always intumescent strips fit into a pre routed groove and are generally self-adhesive. 

However we do stock a surface mounted version that can be fitted where there is a larger gap between the door and frame. 

Intumescent strips should be fitted to the door frame, not the door itself. Fire tests are undertaken with the strip fitted to the frame.  

However, in the case of double doors with plain meeting style one side of the meeting doors should be fitted with a brush seal that butts against a plain strip fitted to the opposite door.  

Commercial buildings, public buildings, residential homes, and places that require fire-resistance ratings as part of building code compliance.

There are 2 common lengths, 2100mm and 1050mm. 2100mm allows for a continuous length to the sides of the door. Strips are easily cut with a builder's knife or small hacksaw.

The 3 popular sizes of intumescent strip are: 10x4mm for 30 minute fire doors, 15x4mm for both 30 minute and 60 minute fire doors, and 20x4mm for 60 minute fire doors. 

Intumescent strips are designed to last for several years when properly installed. However, their effectiveness can be compromised by environmental factors such as excessive moisture, UV exposure, or physical damage. It’s recommended to inspect and replace intumescent strips as part of regular fire safety maintenance, especially after a fire or significant wear and tear.
