2 Hours Fire Rated Ductwork System
Every large residential and commercial project uses HVAC systems to create a comfortable environment within the premises. In order to keep spaces cool or warm, ductwork systems will travel through a multiple of rooms within a building often penetrating roofs, walls and floors. However, these ducts can quickly spread fire if one should break out, transmitting hot gases and toxic smoke around the building. During such cases, the temperature in the duct can be reach up to 800°C and beyond. This elevated temperature rise requires high-end, specialised insulation solutions to protect the people inside these buildings.
Our 2-hour Fire rated ductwork system improves the safe operation of heating, ventilation and air conditioning (HVAC) systems by minimising the chance of fire spread. Effective insulation acts as a barrier between ducts, to slow down or prevent the passage of fire and smoke around the building.
Momansa is almost one and the only company in the region which is having the facility of duct fabrication and fire rated coating application all under one roof. This ensures a quality control, easy co-ordination due to single point responsibility and faster deliveries. Our fully experienced and technically trained Team/ Engineers assist with any technical matter that may arise during installation at site.
Product : STARCOAT CRC
STARCOAT CRC Fire Rated Duct Work System is constructed from galvanized sheet steel manufactured to the DW144, HVCA or SMACNA standard, then degreased and sprayed with STARCOAT CRC coating which is a specially formulated water based compound. This contains selected mineral filters in a low permeability elastomeric binder to a thickness of approximately 700 to 900 micron to give a finished product which has been successfully tested fire conditions in excess of 2 hours’ duration. Ductwork is produced in sections and is assembled on site utilizing tested class ‘O’ gaskets & sealants (CHEMXSEAL 32-17).
The unique properties of STARCOAT CRC have enabled us to design a low density, highly durable material which accommodates induced stress arising from extreme and varying conditions e.g. Climatic Moisture and Structural Loading Variations and the effect of a thermal shock during a fire. The complete system has been tested to BS 476 (Part 20 & 24) – 1987and also up to temperature of 1133°C.
STARCOAT CRC ductwork can either be constructed in flanged lengths of duct, which are then bolted together to make a run of ducting, or in panel form. This construction is especially useful for ducts of large cross-section and can be used on any size of duct up to 25 M x 3 M.
- Tested for up to 2 hours Stability, Integrity & Insulation to BS 476 (Part 20 & 24) -1987and for Ventilation Fire Duct, Smoke Duct & Kitchen Extract ductwork.
- When insulation rating is required panels shall be insulated at the site.
- Total flexibility in the design and construction of the duct.
- Can be sent to site “flat packed” ready to bolt up.
The panels are delivered to site pre-coated on the outside face with STARCOAT CRC and are then bolted together incorporating class ‘O’gasket strip to form the required duct cross-section.
It can have installed for:
- Smoke extract duct
- Car park extract duct
- Kitchen extract duct
- Stair pressurization systems duct
Why Starcoat CRC ?
- Starcoat CRC will provide 2 hours’ fire rating for insulation criteria for smoke extract ducts experiencing temperatures of up to 800 degrees Celsius
- It can help minimise the risk poses and protect lives.
- Starcoat CRC is tested to the most stringent international standards and certified by independent laboratories.
- Starcoat CRC has been approved by all the major MEP consultants / Clients and have been used on various prestigious projects.
- Starcoat CRC has been approved by local Fire and Safety authorities such as CBRI
