Building Construction Handbook, Eighth Edition

(Nancy Kaufman) #1
Overcladding ~ a superficial treatment, applied either as a
component of new construction work, or as a fac ̧ade and insulation
enhancement to existing structures. The outer weather resistant
decorative panelling is `loose fit' in concept, which is easily
replaced to suit changing tastes, new materials and company
image. Panels attach to the main structure with a grid of simple
metal framing or vertical timber battens. This allows space for a
ventilated and drained cavity, with provision for insulation to be
attached to the substructure; a normal requirement in upgrade/
refurbishment work.

Note (1): Cladding materials include, plastic laminates, fibre cement,
ceramics, aluminium, enamelled steel and various stone effects.

Note (2): Anti-bird mesh coated with intumescent material to form
a fire stop cavity barrier.
