Insulated panels are often designed around mullions
and transoms for curtain walling.
They provide an
insulated infill to areas where glazing is not required.
The panels consist of an external skin, usually
aluminium, an insulated core which can be
polyurethane, polyisocyanurate and mineral wool, the
thickness of the core to suit the required U-value, and
a liner sheet.
These components are bonded together
using appropriate adhesive and a heated or vacuum
press.
The table below shows the different thickness of the
most common insulation with typical K-values required
to meet these requirements.
