A range of circular, square and bespoke-shaped metal casings available as double or single skin casings. Double skin casings are manufactured incorporating a 3 mm aluminium outer skin, a 20 mm protective acoustic inter-layer and a 1 mm inner skin, resulting in extremely lightweight and rigid casings. Single skin casings are available incorporating a 3 mm aluminium outer skin and an optional 6 mm acoustic inter-layer. The casings incorporate a fixing method which offers accessibility to enclosed services whilst eliminating all visible fixings. The standard jointing arrangement, allowing all casings to be demountable, provides a 20 mm recess (as standard) in-filled with a metal joint cover to match the casing finish.
