What is Aestuver FPM Fire Protection Mastic?

Fire protection mastic is a type of sealant used to prevent the spread of fire and smoke through joints and openings in fire-rated walls, cladding systems, floors, and ceilings. It expands when exposed to high temperatures, creating a barrier that impedes the passage of flames and toxic gases. This makes it an essential component in maintaining the integrity of fire-rated structures.

What is fire classification of Aestuver FPM fireproof mastic?

Fire classification of Aestuver fireproof sealant depends on the application area.
The FPM mastic has been tested to various design fire curves. 
When sealing and closing of joints and openings and for fire stopping in case of fire up it is classified with fire resistance class EI 120.
In case of tunnel application, fireproof mastic for joint fire protection as well as penetrations in tunnel constructions under fire load RWS 180

Benefits of Using Aestuver FPM Fire Protection Mastic

Using Aestuver fire protection mastic offers numerous benefits, making it a preferred choice for fire safety solutions:

1. Enhanced Safety: By preventing the spread of fire and smoke, it significantly enhances the safety of buildings and their occupants. Aestuver fire rated mastic is classified for EI 120 and also tested for RWS180 in tunnels.
2. Cost-Effective: Its durability and long-lasting performance reduce the need for frequent replacements, offering cost savings in the long run.
3. Versatile Applications: Suitable for a wide range of fire protection needs, from residential buildings to commercial and industrial structures.
4. Environmental Resistance: It maintains its integrity in various environmental conditions, ensuring reliable performance over time.We already mentioned that the fireproof sealant can be used in external conditions. It is worth noting that you can also use this mastic indoors in dry conditions or in rooms with changing humidity or with permanent high humidity. This makes fire protection mastic a great material for wet areas.
5. Compliance with Standards: Adhering to international fire safety standards ensures that buildings meet regulatory requirements.

Applications of Aestuver fireproofing mastic

Examples of fire rated sealant application:

Fire rated ceilings – fireproofing sealant used at the interface between the ceiling boards and wall to allow ceiling movement  

 

Fire rated walls and partitions

Connections between walls and ceilings                                                                    

 Connections to suspended ceilings

 

Connections to fire protected structures steel beams                                                                 

Fire protection of timber

Single- or double-sided sealing of linear joints in ceilings and walls with backfilling

Around Penetrations

You can use Aestuver fireproof sealant around pipes, cables, and ducts that penetrate fire-rated structures, ensuring that these openings do not compromise fire safety. There are numerous MEP services that go through the fire boards. Tight fitting cut-out is nearly impossible and also not advisable. Therefore, the cut-outs within the fire boards are usually slightly larger than the penetrating elements. Any gaps between the fire boards and MEP equipment are filled with fireproof mastic.
