- If the
packs and accessories are to be stored out of doors particular care must
be taken when creating the surface on which they will be placed, a surface
which must have a lengthwise incline in order to avoid the deposit of
humidity.
- Cover with tarpaulins or polythene sheets in the case of adverse weather
conditions, but remove such covers when the sun is shining in order to
air the packs and avoid the formation of condensation.
- If the panels have a galvanized covering they must be mounted within
a few days of delivery; if this should not be possible, the packs should
be taken apart, the panels aired (distancing them one from the other):
if whitish marks should be noted, clean with a cloth greased with vaseline
oil..
- The humidity which may penetrate (rain) or collect (condensation) between one panel an the next may damage the coverings.
- The pre-coated coverings which are further protected by a self adhesive film can resist for a long time as long as they are not in condition of both heat and humidity together.
- The galvanized coverings, on the other hand, may oxidize (with rust) even after a few days, due to electrolytic corrosion if the panels remain in the original packing.
- To store the packs of materials piled one on top of the other, polystyrene foam spacers must be inserted across the way between one pack and the next. The packs must be placed on a surface with an inclination, however slight.
- Flatness
- The panels cannot have perfectly flat faces especially with thin or
aluminium coverings; depending on the amount of light hitting them they
will show ondulations more or less apparent. These will not therefore
be considered a defect as long as they do not compromise the functionality
nor the aesthetic value of the panel, and in particular, as regards this
last point, of the wall panel.
- Blistering - Certain areas will be tolerated in which the covering does
not adhere completely to the foam as long as the total of these areas
is not above 0,5% of the surface area of the panel.
- Small discharges of foam from the joint will be accepted if it is possible
to remove them in the building yard by simply scraping them off.
- Small tracts will be tolerated where the flexible sealing strip is missing
or is not in the correct position as long as it is possible to slot in
the joint without difficulty.
- If the film should be forgotten on the panel once it is mounted, remember to remove it as soon as possible, otherwise (especially in very sunny weather) it will be difficult to take off. Remember furthermore to remove the film inside the overlap, otherwise torn and blackened edges will be seen..
