Ventilation

Air that moves
where it should


Ducted supply and extract, heat recovery and commercial ventilation — set out at first fix so it works quietly and stays reachable.

Spiral ductwork routed through a commercial basement at first fix

01

Commercial ductwork


Rigid spiral for the main runs, insulated flexible for the final connections, and enough thought at the setting-out stage that the duct clears the steel, the sprinkler main and the lighting rather than fighting them.

Supply, extract and make-up air for offices, retail, kitchens and plant rooms — balanced on commissioning and recorded so the figures exist when someone asks for them.

Scope

  • Rigid spiral and rectangular ductwork
  • Insulated flexible connections and attenuators
  • Fan coil units and in-line fans
  • Kitchen extract and make-up air
  • Commissioning, balancing and recorded air volumes
Ventilation grilles concealed within dark timber media joinery

02

Residential & concealed


Heat recovery ventilation for airtight new builds, extract for bathrooms and utilities, and cooling or extract routed through joinery so the grille reads as part of the cabinetry.

On high-specification interiors the ventilation is judged on what you cannot see or hear. That means duct sized generously enough to run slowly, and terminals set out with the joiner rather than after them.

Scope

  • MVHR for new builds and deep retrofits
  • Bathroom, utility and wet room extract
  • Grilles integrated into joinery and cornice
  • Plant located for access, not convenience

How a job runs


01

Survey

A site visit to measure the rooms, check ceiling void depths and structural openings, and find duct routes that clear the steel, the sprinkler main and the lighting.

02

Design & quote

Sized on air change rates and required air volumes in litres per second — not heat load — with duct sized generously enough to run slowly and hit the noise level the room needs.

03

First fix & set out

Ductwork routed and supported alongside the other trades, before the ceilings close. Terminal positions set out with the joiner and the plasterer rather than after them.

04

Commission & balance

Every terminal measured and regulated to its design air volume, the system balanced across the whole installation, and the figures recorded so they exist when someone asks.

05

Service & filters

Planned maintenance to change filters, clean heat exchangers and grilles, and re-check air volumes — the point at which a neglected system quietly stops performing.
