Fixing and Storage
With a coefficient of linear thermal expansion α = 0.08 mm/m°C,
KÖMACEL sheets vary more in length than wood or metal. When
you install screen-printed advertising boards or fix curtain walling
and cladding, possible sheet expansion has to be taken into account.
The appropriate fixing method depends on the application.
Always store KÖMACEL sheets on a dry and even surface in heated
rooms at 15 – 20°C (59 – 68°F). Sheets inside
the packing must not be exposed to weathering and solar radiation.
