Specialist manufacturers of passive fire protection and intumescent paints, Perlita y Vermiculita has over 30 years of experience in developing passive fire protection systems for various environments.
An established company, its products are now available in 5 continents and its manufacturing standards are certified ISO 9001:2008. They are also designed and tested according to the Technical Code of Edification, in accredited laboratories and most of them have the CE seal.
Protection Solutions span the following:
Including Steel Members, Concrete Members, Wood Members, Ventilation Ducts, and Partition Walls.
Mortar for fireproofing structural elements and enclosures. It is a wet-mix spray-applied fire protective rendering made of light weight expanded perlite and vermiculite aggregates.
Low density fireproofing mortar. It is intended for the fire protection of interior structural columns, beams, joists, decks, walls, roofs, girders, floors and pre-cast concrete units. It has been tested and is certified for fire resistance rating up to 4 hours.
Nullifire S 707-60/S 707-120: Waterborne Basecoat is a white thin film intumescent coating for the fire protection of internal structural steelwork. S707-120 can provide up to 120 minutes fire resistance.
Nullifire S 707-60/S 707-120 main features:
Perlita y Vermiculita has developed different systems for fire protection for the chemical and petrochemical industries. These specialised environments work with highly flammable products and as such, the risks of explosion or fire(s) are exponentially greater.
In addition, studies and historical data from real fires have demonstrated that these fires ignite and spread much faster than in normal situations.It is imperative that the right fire protections are in place.
One of the main measures taken in the chemical and petrochemical industry is the simulation of a fire curve which is more aggressive than that used in construction. Studies and data from real fires have shown that these industrial fires develop much faster than normal characteristics fires.
Currently there are different models that simulate this behaviour. The most prominent are the NPD (Norwegian Petroleum Directorate), developed in Europe, and the curve UL 1709 (Rapid Rise Fire), developed in the United States. Both curves can be used as test curves for the certification of passive protection products in the chemical and petrochemical industry.
A high density, exterior grade, heavy duty, cementitious fireproofing material ideal for use in industrial and petrochemical environments.
Provides1 to 4 hour(s) of fire protection for structural steel, vessel skirts, bulkheads, LPG vessels, LNG terminals or to upgrade the fire resistance of existing concrete.
Suitable for both field and shop applications when applied by our published application procedures. The superior physical properties of Pyrocrete 241 promote high durability when handling, during construction, and while in service.
Damage from fires in tunnels always has a very high cost, on both the human and financial scale. By its very design nature, tunnels rapidly become ovens in a fire situation, resulting in concrete rubble caused by exploding aggregate blocking access/exits to extinguish/escape.
The human and financial cost of damage from fires in tunnels can be deleterious. By its very design nature, tunnels rapidly become ovens reaching extremely high temperatures in a fire situation, resulting in concrete rubble caused by spalling (exploding aggregate) blocking access/exits to extinguish/escape.
When designing a tunnel, it is necessary to take these factors into consideration, to provide for alternative escape routes, proper ventilation, to install fire detection systems, and to develop passive fire protection for the tunnel’s structural elements. For example, a system to protect the concrete structure is critical, since temperature gradients between the interior of the concrete are greater, given the increased heat that spalling causes.
The cost of repairing a tunnel affected by fire is far lower if a system of passive protection is already in place.
A single powder component mixed with clean, potable water before it is used in application. Recommended use for tunnels.
