Recommendations for the selection of boards in the context of thermal loads

When designing, the temperature differences between the sandwich panel facings should be taken into account. The temperature gradients resulting from the difference in temperature between the outside temperature T 1 and the inside temperature T 2  depend on several factors:

  • purpose of the facility (temperature range inside the facility – T 2 )
  • object location – location in relation to the sun
  • color of the outer cladding (T 1 ).

Depending on latitude, altitude and distance from the sea on the European continent, four different levels of winter temperature (T1 – external cladding) are used:

  • 0, -10 o C,
  • 0, -20 o C, (e.g. Poland)
  • 0, -30 o C, (e.g. Scandinavian countries)

The temperature of the external cladding for roof panels covered with a layer of snow cover is 0 ° C.

For the calculations, the outside temperature in winter was assumed to be -20  o C.

The temperature of the outer cladding T 1  is the maximum in summer and depends on the color and degree of reflection of the surface. The values ​​of T 1 , which are the minimum for the Ultimate State (ULS) design and relevant for the Service Limit State (SLS) design, are taken as follows:

  • very bright colors R G  = 75-90 T 1  = +55 o C
  • bright colors R G  = 40-74 T 1  = +65 o C
  • dark colors R G  = 8-39 T 1  = +80 o C

where R G  – is the degree of reflection of rays in relation to magnesium oxide = 100%

NOTE – Group III – dark colors

  • Recommendations for the selection of boards in the context of thermal loads

Taking into account that the dark-colored panels from group III are subject to much greater thermal loads than the very bright and light-colored panels from groups I and II, it should be assessed during the design, depending on the loads, what arrangement of panels on the wall is possible ( 1-span, 2-span, multi-span), horizontal or vertical arrangement. In addition, a very important matter is the selection of max. the length of the plates. The arrangement of the load-bearing structure should be designed for the appropriate static arrangement of the panels, taking into account the widths of the supports (transoms and purlins), their maximum spacing and the number of connectors.

In addition, during the design process, particular care should be taken to ensure that the following conditions are met:

• the method of fastening and the static system must be in accordance with the tables of permissible loads and spans (criteria met – ultimate limit state, operating limit state) *

• the length of the boards should be selected in such a way as to meet the limits indicated by the manufacturer of the boards **

• the panel assembly temperature must be taken into account. ***

• panels with facings with smooth profiling may be used / installed only in a single-span system

* For panels in dark colors, single-span systems are recommended; Otherwise, the intermediate supports may experience unacceptable by the Investor deformation of the external cladding of the panel. The waves in question meet the requirements of PN-EN 14509: 2013-12 in terms of permissible deviations, however, they may cause deterioration of the aesthetics of the panels, as a consequence of complaints.

** The maximum board lengths should be in accordance with the manufacturer’s guidelines, depending on the type of board and their application (roof / wall) – see LENGTHS. For plates in dark colors, longer than those mentioned in point 4, table 2, the company Pruszyński does not provide a guarantee, unless such use has been previously agreed in writing with the authorized representative of the company Pruszyński.

*** Installation of PIR sandwich panels with dark cladding (III color group) should be carried out at the outside air temperature ranging from + 10 ° C to + 35 ° C.

Immediately before assembly, (~ 20 min.) The dark cladding of the sandwich panel (usually it is the external cladding), should not be exposed to direct sunlight, as it may cause excessive heating of the cladding / cladding and its deformation.

The wall panels in the bundle are placed with the façade side up. It is recommended to shield the facade cladding in the package from the sun. If the slab packages on the construction site are stored in direct sunlight, it is recommended to put the first slab in the bundle away, cover it or turn the inside of the slab to the sun. Subsequent panels taken from the package should not be exposed to the sun for more than 20 minutes before fixing them.

It is necessary to pay attention to the above aspects during installation, because the temperature of the outside air affects the aesthetics of the facade and the correct operation of the panel.

In this case, deformation and damage to the panel are caused by high elongation of the cladding (e.g. at summer temperatures) in relation to the initial length (cladding length during installation). Installation of light and very light colors is possible in the temperature range from + 5 ° C up to + 35 ° C.

Failure to comply with the above guidelines may result in surface deformation on the plates and local loss of stability, for which the manufacturer is not responsible. In the case of colors not listed in the table, please contact the technical advisor of the Pruszyński company. The plate color may only be changed with the consent of the designer.

CONNECTING PWD-PIR ROOF PANELS ALONG THEIR LENGTH

When joining the roof panels along their length, it is necessary to make an undercutting of the upper panel, i.e. the panel on the ridge side.
PIRTECH roof panels can be produced with a ready undercut in the range from a minimum of 50 to a maximum of 300 mm.
It is enough to choose the type of undercut (see fig.), Which is determined by the assembly direction:

  • undercut LEFT   – assembly from the left side
  • undercut RIGHT – assembly from the right side


The length of the undercut can be: D = 50, 100, 150, 200, 250 and max. 300 mm.

NOTE: The total length of the slab includes the selected length of the cut, regardless of its size.

For example, a plate with a length of 6000 mm with an undercut of 200 mm = 6000 mm (5800 mm core + 200 mm sheet).

The Blachy Pruszyński company makes two types of undercuts:

– full undercut, i.e. cutting of the inner sheet, tape on the outer-trapezoidal lining, undercut of the foam along the entire thickness of the panel’s core,

– incomplete undercut, i.e. cutting of the inner sheet, undercut of the foam along the entire thickness of the panel core.

Individual widths of the undercut (only in the range from 50 to 300 mm) are possible, but without the tape on the outer – trapezoidal lining with the foam undercut along the entire thickness of the panel core.

For PWD-PIR panels 40, 60, 80, 100, 120 min. the length of the panels with full undercut is 5,000 mm. Boards with lengths below 5,000 mm can be made only without tape on the outer – trapezoidal cladding.

For PWD-PIR panels 160 min. the minimum length of boards with full undercut is 4,000 mm. The PWD-PIR 160 panel with a length of less than 4,000 mm can be made only without tape on the outer – trapezoidal facing.

 

 

 

TRANSPORT RECOMMENDATIONS

Recommended means of transport for sandwich panels:

  • a truck (truck tractor + semi-trailer with a length not shorter than the length of the loaded plates) with the semi-trailer open or allowing side loading on both sides along its entire length
  • the weight of the load must not exceed the maximum load capacity of the set,
  • transport belts should be placed on the load at a distance of max. every 3 m, but not less than 2 belts for one package – the tension of the belts must not cause deformation of the panels.

STORAGE RECOMMENDATIONS

Sandwich panels should be stored in packages (posts), it is allowed to store up to two packages on top of each other.

The table below shows the max. number of boards that can be placed in one package.

40 mm18 pcs.
60 mm14 pcs.

100 mm8 pcs
120 mm8 pcs
160 mm6 pcs

 

  • It is recommended to store the boards on an even surface (square, hall) on polystyrene joists or sleepers, which must be spaced at most every 2.5 m (for boards with a total length of up to 2.5 m, at least 3 underlays should be used).
  • It is allowed to store a maximum of two packages of boards up to 6m on top of each other, in the case of packages of boards over 1m, they should be stored individually. All plate packages must be stored on an even surface with the possibility of drainage.
  • During the storage of panels on the construction site, they should be protected against mechanical damage, exposure to UV rays, aggressive environment (acids, fertilizers, salts and other corrosive agents), precipitation, strong wind and others.
  • It is recommended to store the packages under a roof in ventilated rooms
  • The boards should be stored on an even surface (square, hall) on joists, polystyrene or wooden sleepers, which must be spaced at most every 2.5 m (for boards with a total length of up to 2.5 m, at least 3 sleepers should be used. ).
  • Protective films are used to additionally protect the surface of the panels against mechanical damage, stresses and impacts that may occur during transport or handling. The foils never release you from the obligation to properly protect the panels during storage.
  • It is recommended to remove the protective film before mounting the elements on the facade or roof of the building. The foil should be removed when the air temperatures are positive, because the adhesive delaminates at negative temperatures and some of its components may remain on the sheet.
  • Improper sheet storage may cause difficulties in removing the protective foil and leave traces of glue on the surface of the boards. In such cases, complaints about the remnants of the adhesive from the protective film will not be considered by the Manufacturer.
  • In the case of panels with hidden fasteners, make sure that the foil is removed from the inside of the longer lock before assembly.

ATTENTION !!!

In the case of wall panels with visible fastening (applies to PIR panels), the upper side of the panels in the package is the façade side, which should be taken into account in particular!

MAINTENANCE AND WASHING

In order to extend the service life of roofs and facades made of coated metal sheets, they should be regularly inspected and maintained.

  • Inspection –  Once a year (preferably in spring), the roof / facade should be inspected for early detection of possible damage.
  • Sheet cleaning – Roofs / facades made of coated sheet metal require cleaning at least once a year. Dirt settling on the sheet can cause uneven discoloration (the result of uneven exposure to UV rays), and also reduce corrosion resistance (dirt retains moisture on the sheet and gradually damages it). Dirty and stained places can be cleaned with a soft brush and water (temperature max. 60 ° C). If necessary, it is allowed to add a mild detergent to the water (pH 6 ÷ 7, max. 10% solution). Pressurized water (max. 100 bar) can also be used for cleaning, however, the water jet cannot be used too close to the board surface (min. 30 cm), and it cannot be directed perpendicularly to the surface. At the connectors, the stream of water should be directed downwards so that to avoid the ingress of pressurized water into the gaps around the fittings. Old board coatings must be handled with extreme care. Washing should be carried out from the top downwards and the cleaned area should be immediately and thoroughly rinsed with clean water.
  • Scouring powders, nitro solvents, chlorine solutions, aromatic agents as well as agents containing ammonium chloride or sodium salts must not be  used.
  • Damage – Any damage during the warranty period must be consulted with the Roof / facade Contractor and may be made only with his written consent. Damage to small areas is repaired with air-drying paints, while painting large areas is generally only possible with special industrial paints suitable for renovation of coverings. The surface to be painted should be limited only to the places that require it (scratches to the metal layer, corrosion centers, etc.). Preparation of the surface for painting should be performed according to generally accepted rules. Any signs of corrosion should always be thoroughly removed – preferably with special brushes or fine sandpaper. Then, the surface to be repaired must be thoroughly dusted, degreased and cleaned. To degrease the surface, you can use gasoline or water with the addition of surfactants (preferably with the addition of 1-2% ammonia solution). The areas to be repaired may show differences in color compared to the original colors of the sheets due to the natural influence of atmospheric phenomena (paint aging under the influence of UV radiation).
  • CAUTION – During inspection, cleaning, maintenance and repairs, safety rules must be strictly adhered to.
