Transforming Elevated Spaces: The Permeate Planter System

Modern architecture increasingly blurs the line between buildings and outdoor environments. Rooftops, balconies, and podiums are no longer leftover spaces—they’re valuable real estate for designers, developers, and end users. Into this landscape enters Wallbarn’s Permeate Planter System, a game-changing solution blending structural integrity, aesthetic appeal, and sustainability—all within one elegant, modular package.

1. A Fully Integrated System

At its foundation, Permeate merges Wallbarn’s renowned Class A fire‑rated substructure with bespoke planter units and seating elements crafted by Bespoke Metal Planters. This seamless integration means that the system can support:

• Hard landscaping (decking, paving)
• Soft landscaping (planters, greenery)
• Furniture (FSC‑certified hardwood or metal benches)

This unity offers not only visual harmony but also structural reliability, making it suitable for high-rise rooftops, commercial terraces, and public podiums.

2. Structural Strength & Flexibility

A key advantage is the MetalPad Ex pedestals, offering adjustable heights from 26 mm to 375 mm, versatile enough to address uneven substrate or insulation build-ups..

These pedestals support Wallbarn’s aluminium I‑Plus joists (available in 50mm, 75mm, 100mm), which slot seamlessly into galvanised-steel trays. These trays, complete with drainage holes, securely clip into place—no complex fixings required (wallbarn.com).

As a result, whether laying porcelain tiles, timber decking, or integrated benches, installers benefit from a robust yet user-friendly framework—drastically reducing on-site labour and waste.

3. Efficient Drainage & Longevity

Drainage is paramount in elevated landscaping, and Permeate excels here with trays designed to prevent water pooling. Combined with drainage structures within planters, this protects waterproofing membranes below and maintains plant health—all while extending the system’s lifespan.

4. Durable, Premium Materials

Permeate’s build quality is impressive:

• Class A fire-rated components, including pedestals, joists, fixings and Connectors, all meet the highest safety standards.
• Metals used include galvanised steel, aluminium, and Cor‑Ten, coated with Qualicoat polyester powder for corrosion resistance.
• Planters are crafted from aluminium, hot-dipped galvanised steel, or corten steel, in thicknesses of 3–4 mm—built to last with minimal corrosion risk.

These meticulous material choices ensure both durability and aesthetic longevity.

5. Bespoke Planters & Seating

Functionality meets design with planters and benches that blend into the overall landscape. Customisable by colour (RAL/BS), finish, and material, these elements create a cohesive aesthetic .

For seating, Permeate offers:

• FSC-certified hardwood benches
• Class A metal or composite options
• Timber alternatives like European Oak and Thermo-Bamboo for BRoof T4 compliance 

Modularity ensures these benches slot into the substructure effortlessly, giving designers flexibility in layout and function.

6. Seamless Hard Landscaping

Whether clients opt for porcelain tiles like ExaDeck, cement-fibre CDeck, aluminium decking, or traditional timber such as Bamboo Elegance, Permeate accommodates them all.

Porcelain paving is especially suited to areas needing quick access for maintenance—individual tiles can be lifted without disturbing the overall surface.

7. Green Rooftops & Biodiversity

Partnering with Green Roofers UK, Permeate allows full-scale intensive or lightweight extensive green systems. These installations offer multiple environmental benefits:

• Attract pollinators and increase biodiversity
• Improve air quality, reduce heat island effect
• Provide rainwater attenuation and CE/Thermal insulation

These green spaces also deliver well-being benefits, supporting employee productivity and general health.

8. Weight Distribution & Safety

Optional spreader plates safeguard membranes by distributing loads more evenly. Combined with Class A fire safety fixings, the system stands up to rigorous regulatory compliance .

9. Simplified Installation & Maintenance

Permeate’s modularity and clip-in trays make installation and upkeep efficient:

• No mechanical tray fixings
• Easy access for maintenance of deck tiles, drainage, or cables
• Quick disassembly and replacement minimise disruption

This transparency delivers value across the project’s lifecycle.

10. Comprehensive Project Support

Wallbarn goes beyond product supply by offering:

• Concept planning with CAD/DWG visuals
• Budgeting estimates
• Site visits and compliance checks
• Scheduled deliveries, installation, and post-install maintenance 

This full-service support ensures projects run smoothly from inception through long-term operation.
