PIRTECH Wall panels The refrigeration wall (visible attachment) with a maximum modular width of 1150 mm allow for simple and quick installation to various types of structures using appropriate through fasteners. The uniquely designed longitudinal contacts (locks) of the pen and wpust ensure very good tightness, fire resistance and quick assembly.
Dedicated to use as external partitions, ceiling covers (with tropics) and internal walls in refrigerated facilities and frost.
Pruszyński Company guarantess realization of each order in one colour shade. Although due to technological process of covering paint to steel shets there is possibility for occuring difference in colour shade in different deliveries.
Regarding this please inform sales person if different delivery is continuation of previous orders.
In order to ensure color consistency of sandwich panels with other elements such as flashings, they should it ordered from one supplier.
During projecting it’s important to include difference in temperature of external and internal cladding of sandwich panels.Gradients of temperatues due to difference in external temperature T1 and internal temperature T2 are dependent on few factors:
Purpose of building (range of temperatures inside building T2)
localization of building – position due to sun
colour of external steel cladding (T1).
Depending on latitude, height above sea level and distance from sea on europe continent are use 4 different levels of winter temperature (T1 – external cladding):
0, -10oC,
0, -20oC, (for ex. Poland)
0, -30oC, (for ex. scandinavian countries)
Temperatures of external cladding of roof panel which is covered with snow layer is 0oC.
For calculation was assumed external temperature in winter of -20 oC.
Temperature of external cladding T1 has maximum value during summer and is depending of colour and grade of reflection of surface. Values T1, which are minmal for calculation bearing status (SGN) and are proper for calculations of limit status of use (SGU) are:
where RG – grade of reflextion in ratio of magnesium oxide = 100%
Permissible panel lengths depending on the color of the cladding (minimum length - 2.5 MB).
16 m
12m (wall)/15 m (roof)
9m (wall)/12 m (roof)
Taking in consideration that dark colours from group III has much bigger thermal load and very bright and bright colours from groups I and II, there should be paid special attention during projecting and below conditions are complained:
* For panels with dark colours recommended are single-span schemes; in other case there may occur non-acceptable by Investor strains on external claddings on panels on intermediate supports. Flutings which may occur, complain with norm PN EN 14509 due to acceptable deviation, but may be topic of complaints.
** Maximum length of panels should be in accordance of producer’s guidelines due to type and use of panels – see LENGTH OF PANELS
*** Assembly of panels with dark colours is possible within temperatures 10oC to 35oC. This condition is essential and must be strictly observed.
Assembly of panels in very bright and bright colours is possible within range of temperatures from +5oC to +35oC
Recommended ways of transport for sandwich panels:
Sandwich panels should be storage maximum 2 packages one on another.
In below chart you can see what is maximal quantity of panels in one package.
| thickness of panel | PWS-PIR-CH |
|---|---|
| 120 mm | 9 pcs. |
| 160 mm | 7 pcs. |
| 180 mm | 6 pcs. |
| 200 mm | 5 pcs. |
| 220 mm | 5 pcs. |
ATTENTION !!!
All packages should be storage on flat surface with possibility to discharging water.
In case of panels with visible fix(PIR-CH), upper side of package is elevation side, which is very important.
In order to extend durability of roofs and elevations it’s recommended to check and conservative it.
