Fire safety is an important consideration on active construction sites, especially where welding, grinding and other heat-generating activities are taking place.
PAC® Shuttering Boards provide a durable Construction Plastic Board alternative to conventional timber formwork, offering tested fire and mechanical performance for demanding construction applications.
Fire Performance of PAC® Shuttering Boards
PAC® Boards are manufactured using industrial packaging material along with reinforcing components such as XLP fibers, aluminium oxide and metal dust powder.
According to the test data provided for PAC® boards, the material showed no burn-through after 5 minutes of flame exposure, with only superficial blackish discoloration reported.

Why Fire Performance Matters on Construction Sites
Construction sites can involve welding, cutting, electrical work and other activities that create heat or sparks. Using formwork with tested fire-performance characteristics can be an additional consideration when planning site safety.
PAC® Shuttering Boards can be used for suitable applications in:
- High-rise construction
- Industrial projects
- Basement and foundation work
- RCC slabs and columns
- Repetitive formwork applications
Check the Certification Before Procurement
For any project where fire compliance is a requirement, contractors and consultants should verify the latest product-specific test reports and applicable IS-code requirements before procurement.
This helps ensure that the selected board is appropriate for the project’s specific fire-safety and formwork requirements.
40% Buyback Program
PAC® Shuttering Boards can also offer value beyond their usable cycles through Rajratan’s 40% buyback program on eligible boards.
This can help reduce the effective material cost while supporting a more circular approach to formwork material use.
Conclusion
Fire safety, durability and reusability are important considerations when selecting construction formwork.
With tested fire-performance data, mechanical strength and a reusable design, PAC® Shuttering Boards provide an alternative to conventional timber shuttering for suitable construction applications.
For technical specifications and project suitability, consult the latest PAC® product test documentation before use.
