Every brief starts the same: a space that must breathe but can’t afford to leak energy. Tight budgets, tighter carbon targets, awkward floor plates, heritage facades. Yet occupants still demand perfect comfort. That’s where our in‑house technical experts and engineers step in. Because we design and manufacture every component of the natural ventilation range, we can tailor our systems to fit your project, no “off‑the‑shelf‑or‑nothing” compromises.

Why our natural ventilation range?

• Up to 75 % heat recovery – comes as standard for our Mistrale Fusion Evo MFS-HR-CE

• Best‑in‑class airtightness – meeting and exceeding TM23 regulations

• Factory‑built, off‑site modules – rapid install, predictable quality, risk reduction

• Flexible by design – customised grilles, dampers and louvres for unique layouts

• Whole‑life carbon wins – smaller plant rooms, ultra‑low fan power, easier maintenance

• Regulation ready – proven compliance with BB 101, Part L, DfE specification and net zero frameworks

Bring us your most challenging footprint or retrofit and we’ll create a natural‑plus‑hybrid system that breathes efficiently and fits first time.
