When the Natural History Museum installed its new, real-life skeleton of a blue whale, Gilberts provided a ventilation solution for the Grade 1 listed Hintze Hall.
Based on CFD modelling, Gilberts manufactured and supplied 24no of a bespoke version of its Mistrale Model A natural ventilation units, with a further 42no standard WHF50 high performance louvres.
Each of the bespoke units used a combination of Gilberts’ WHF50 cassette with its VN75 ultra low leakage air volume control damper, to fit within existing window apertures and frames, and bolt together into specially-designed subframes. Gilberts also devised a bespoke combination of internal K40 fixed bar grilles and non vision cores mounted on the rear of the units.
In a separate high level atrium, the original glass in the window frames could be removed; there, the glazing was replaced with Gilberts’ WHF50 louvres to provide high level exhaust of the ’used’ internal air.
