What Wallbarn does

Wallbarn Limited is a UK-based, privately held specialist construction products company that designs, supplies, and distributes integrated systems for raised paving, decking, and green roofing on flat roofs, terraces, podiums, and balconies. The company is incorporated in England (company number 01500958) and operates from a South Croydon headquarters with a registered address in Dudley, holding ISO 9001 and ISO 14001 certifications and NBS Source Partner status for UK architectural specification.

The product portfolio spans five core categories — adjustable pedestals (Minipad, Universal, Balance, Mega Balance, MetalPad D/Ex, Fixed Height), Class A and B fire-rated systems (MetalPad Ex pedestals, I-Plus aluminium rails, ExaDeck porcelain boards, Class A Silicone), green roofs (the registered M-Tray® modular system plus wildflower and pollinator variants), decking (iDecking EasyClick system with DURO Excellence composite boards, Thermo Bamboo, tropical hardwood, composite boards, timber tiles), and protection/drainage (Protecto-Mat, Protecto-Board, geotextiles, drainage outlets). The portfolio is anchored by proprietary engineering including self-levelling Balance pedestals rated to 683 kg per unit and tested between +75°C and -40°C, the MegaPro estimating software that generates colour-coded layout plans, and a rail-pedestal lug-fit design that accommodates thermal expansion without mechanical fixing. The ExaDeck line is delivered through a strategic partnership with FireDeck.

Wallbarn generates revenue through one-time transactional sales of physical construction products to a B2B customer base that includes construction contractors and installers, architects and specifiers, property developers, and (to a lesser extent) private homeowners. Pricing is quote-based with no public list pricing; orders are taken via phone (020 8916 2222), website enquiry forms, and live chat, with next-day delivery available on most items and credit terms typically offered to established B2B accounts. The company sells direct rather than through resellers, and its marketing relies on trade association memberships (NBS, NFRC, RIBA), an extensive library of project case studies, and active social channels (Instagram, X, YouTube, Facebook) plus a monthly email newsletter distributed via Sage and Act! CRM.

Core offering

Wallbarn manufactures and supplies specialist construction products for raised paving, decking, and green roofing on flat roofs, terraces, balconies, and podium decks. Its integrated portfolio comprises adjustable support pedestals (Minipad, Universal, Balance, Mega Balance, MetalPad D/Ex, Fixed Height), aluminium rail substructure (I-Plus, Box Rail, Class A fire-rated rails), decking boards (iDecking with DURO Excellence composite, ExaDeck Class A porcelain, Thermo Bamboo, tropical hardwood, timber tiles), modular green roof systems (M-Tray, Wildflower, Bee Bus Stops, roll-out), and protection/drainage products (Protecto-Mat, Protecto-Board, geotextiles, drainage outlets). Products are sold to UK construction contractors, installers, architects, and property developers, with MegaPro estimating software supporting project planning.

Product overview

Wallbarn is a specialist construction products company offering a comprehensive range of innovative products for the building and construction industry. The portfolio comprises five core product categories: Pedestals (adjustable support pedestals including Minipad, Universal, Balance, Mega Balance, MetalPad D/Ex, and Fixed Height), Green Roofs (M-Tray® modular systems, M-Tray® Wildflower, M-Tray® Bee Bus Stops, and roll-out systems), Decking (iDecking system with DURO Excellence composite boards, ExaDeck fire-rated porcelain, Thermo Bamboo, tropical hardwood, composite, and timber tiles), Substructure (I-Plus aluminium rails, Box Rail, fire-rated rail systems, and associated fixing clips), and Protection & Drainage (Protecto-Mat, Protecto-Board, geotextiles, drainage outlets). These products work together as an integrated system for rooftop terrace construction: pedestals support the substructure, which carries the decking or paving surface, while green roof systems provide vegetation coverage. The company also supplies complementary accessories including clips, fixings, oils, and maintenance products, along with MegaPro estimating software to support system planning and installation.
