What Interalu does
Interalu nv is a Belgian private company founded in 1971 and headquartered at Fotografielaan 49-51, Antwerp, that designs, manufactures, supplies, installs, and maintains metal and climate ceiling systems. Its product portfolio is organized into two pillars: climate ceilings (SAPP Ceiling, Easy-KlimaPlus, and WEC), which integrate radiant heating and cooling into suspended ceiling panels to deliver stable indoor temperature without draughts, and metal ceilings (BL, CL, WL, and XL Ceiling lines), which provide acoustic comfort, design flexibility, and durability for commercial and institutional interiors.
The company sells through direct project collaboration with architects, engineers, contractors, and investors, embedding its specifications from early design through final installation. Its target verticals are offices, healthcare, education, hospitality, and public buildings. Pricing is not publicly disclosed; quotes are routed through [email protected]. Interalu operates a localized multi-market digital footprint with websites in Dutch, French, German, English, Italian, and Polish covering Belgium, the Netherlands, Luxembourg, France, Germany, Italy, and Poland, and maintains a dedicated French-market sub-brand called Smart Ceiling (smartceiling.fr).
Firmographically, Interalu is a private Belgian entity (legal form nv, VAT BE 0408 394 744) with 11–50 employees, no disclosed subsidiaries, no parent company, no funding rounds, and no public listing. Content marketing assets include a published reference book of European projects and downloadable technical documentation in multiple languages. The company's stated differentiators rest on over fifty years of domain specialization, proprietary climate ceiling product names, and a sustainability- and acoustics-led value proposition rather than on software, data, or AI capabilities.
