Why specifying a fire rated paving and decking system matters
For residential buildings with any storey 11 m or more above ground level, guidance in Approved Document B states balcony and terrace elements should be non-combustible. Wallbarn provides fully non-combustible paving and decking solutions where the substructure and support components meet Class A specification and deliver compliant, independently tested results
 |
When you typically specify
High-rise residential at or above 11 m. Multi-occupancy balconies and communal terraces. Podium decks above occupied or public areas. Refurb projects being brought into line with current fire strategies |
 |
Class A components
MetalPad Ex steel pedestals with Zintec 200 coating, aluminium Box and I-Plus rails, and metal headpieces and fixings. Non-combustible components designed for compliance |
 |
Built for Precision
MetalPad Ex adjusts to millimetre accuracy for exact levels. Our Box and I-Plus rails are high-quality extruded aluminium, creating a perfect, lay-flat platform for tiles, slabs or decking |
What we offer
Every component is Wallbarn-designed to work as one system.
