Crossflow

What Crossflow does

Crossflow is a family-run Irish building services company, founded in 1972, that designs, supplies, installs, commissions, and maintains smoke ventilation systems, architectural louvres, and air conditioning solutions for commercial, institutional, and infrastructure clients across Ireland and the United Kingdom. Its core portfolio spans smoke control (firefighting smoke shafts, AOV smoke ventilation, smoke and fire curtains, stairwell pressurisation, and car park ventilation), architectural louvres and brise soleil (acoustic, high-performance, storm, screening, and clipless variants, with in-house CLS blade profiles and custom Decral finishes), and air conditioning covering VRF/VRV systems (Mitsubishi Electric City Multi, Daikin VRV IV, Fujitsu Airstage), split systems, and STULZ precision cooling for data centres, supported by an Advanced Field Solutions (AFS) web-based maintenance platform and Computational Fluid Dynamics (CFD) engineering services.

Crossflow operates an integrated manufacturer-distributor-installer model: it manufactures its own CLS louvre systems in-house, holds exclusive Irish distribution rights for Bilco (roof access), Sertus, and Fieger, and is a partner channel for Brakel Life Saving Products, Aumuller actuators, Duco solar shading, Kingspan Light + Air, HC Groep, BLE smoke and fire curtains, Elta fans, and Stulz precision cooling. The business monetises through three revenue streams: equipment supply (proprietary and third-party hardware), design-installation-commissioning services sold via turnkey project contracts, and recurring service and maintenance contracts (350+ active maintenance customers with 24/7/365 emergency response). Pricing is project-specific and not publicly disclosed; free site surveys are used as a customer acquisition tool, and sales motions run direct to architects, main contractors, M&E consultants, and end-client building owners and facilities managers.

The company is privately held by its founding family with no disclosed institutional investors or parent company. It runs a small headcount (11-50 employees) across two offices: the Dublin headquarters at Western Industrial Estate and a UK regional office in Holborn, London. Anchor relationships include ESB (25+ years), Allianz Worldwide Care (20-25 years), the Office of Public Works, Temple Street Children's University Hospital, and FBD Insurance, alongside flagship projects such as Rosslare Europort Terminal 7 and the BREEAM-rated Ironworks Dundrum development.
