Fire Rated Paving Systems Explained: Safety, Stability & Style for Roofs, Balconies & Podiums

As construction standards tighten across the UK, ensuring that external surfaces are both safe and durable has never been more important. The fire rated paving system from Wallbarn delivers a fully compliant, non-combustible solution for roof terraces, podiums, and balconies, combining safety with structural integrity and aesthetic flexibility.

Why Fire Rated Systems Are Essential

Recent changes in building regulations require non-combustible materials to be used in certain high-rise and sensitive projects. Wallbarn’s Class A fire-rated solutions meet these requirements, offering peace of mind for architects, contractors, and specifiers.

The fire rated paving system ensures that porcelain tiles, concrete slabs, or natural stone are securely supported on a non-combustible framework. This eliminates risk while maintaining a high-quality finish across outdoor areas.

Built for Multiple Surfaces

The system is designed to work with a variety of finishes, including:

• 20mm porcelain tiles

• Concrete paving slabs

• Natural stone

• Flags at least 50mm thick

This adaptability allows designers to create attractive outdoor spaces without compromising on safety or durability.

Strength and Stability

One of the key benefits of the fire rated paving system is its enhanced stability. By tying the entire structure together through the substructure, it reduces the risk of individual tiles or slabs shifting over time. The result is a sturdy, long-lasting surface capable of withstanding the demands of busy public or residential use.

By working in conjunction with MetalPad EX pedestals and I-Plus aluminium rails, the paving system ensures consistent load distribution and long-term performance.

Coping with Uneven Subfloors

Construction projects rarely deal with perfectly level surfaces. Roof decks and podiums often have undulations or varying levels. The fire rated paving system addresses this challenge with a stable substructure that can be adjusted to compensate for irregularities.

This makes it particularly useful for retrofitting projects or urban redevelopments where existing subfloors are less than ideal. Wallbarn’s wider range of substructure systems ensures that even the most complex designs can be supported.

Easy Access for Maintenance

Unlike mechanically fixed solutions, the fire rated paving system does not permanently lock tiles in place. Instead, slabs and tiles sit securely on the framework without being bonded. This allows for straightforward removal whenever access to the substructure, drainage, or services beneath is required.

This ease of access saves both time and cost for ongoing maintenance and inspections, making it a practical long-term choice.
