17. Application Back to contents page

18. The panel system is used in facades, partition walls, ceilings and compartmenting structures The panels are categorized in four different groups each of which has their own special application It is important to use the right panel to right place – it is cost efficient and practical Sandwich panel SPA - application

19. Typical applications –Industrial buildings –Air-conditioning and ventilation structures –Agricultural buildings –Construction for the food industry and clean rooms –Logistics centres –Power plants –Office and commercial buildings –Sports facilities Sandwich panel SPA - application

20. PVDF coating is recommended for the exterior sheet of the lightweight sandwich panels Polyester coating is the best option for the interior sheet, but can also be used for the exterior sheet PVDF coating is recommended for normal exterior use. It is highly resistant to UV radiation and dirt PVDF is recommended for uses where excellent colour and gloss durability and dirt resistance are needed Sandwich panel SPA - application

21. PVDF HB is a thicker than normal coating It is recommended for use in environmental conditions where excellent corrosion resistance is important, such as marine and industrial environments Sandwich panel SPA - application

22. Polyester coating can be used both on interior and exterior sheets Its colour durability and corrosion resistance are good In the food industry, polyester can be used if it is not in direct contact with food More information about coatings: –Go to Ruukki Academy site and find the raw materials and coatings presentation Sandwich panel SPA - application

24. Sandwich panel SPA - application With SPA Panels you can meet the new U-value regulations that became effective on January 2010 Notice, that there are several possibilities to meet the regulations in case of semi-warm building (a building that is not meant for constant living, temperature +5 - +17 o C on heating period) The panel U-values are presented later on this presentation

25. As the title describes, external wall panels are to be used as an external walls Good characteristics in terms of U-value The bolded panel models are so called “standard range” – most often used Panel types – External

26. As the title describes, internal wall panels are to be used as an internal walls, partition walls, compartmentation walls etc. Good characteristics in terms of light weight and handling property The bolded panel models are so called “standard range” – most often used Panel types– Internal

27. As the title describes, fire resistant wall panels are to be used as a structure, which requires special fire resistance Good characteristics in terms of fire resistance The bolded panel models are so called “standard range” – most often used Panel types – Fire structures

28. As the title describes, fire resistant wall panels are to be used as a structure, which requires special strength (long spans, heavy wind loads…) Good characteristics in terms of strength The bolded panel models are so called “standard range” – most often used Panel types – Strong structures

29. The fire technical properties of the panels have been tested with regard to fire resistance and properties of the materials The fire class of the panels is A2-s1, d0 (coatings PVDF and Polyester) With panel type S it is possible to build EI240 wall constructions and light-weight EI-M firewall structures up to EI-M 120 –M = Mechanical durability under fire Sandwich Panels – Fire resistance

30. In compartmenting structures, the panel and its fastenings need to be dimensioned, at least, for the variable 0.3kN/m 2 load Panels shall not, length- or widthwise, extend from one fire compartment to another In fires the panels act as a catenary structure. The fastening and dimensioning shall be done according to instructions If the applications have certain fire resistance requirements, the maximum allowed spans shall be equal or less to those in the following tables, at most Sandwich Panels – Fire resistance

31. Maximum spans and fire resistance for External wall panels The first number stands for horizontal installation and the following one for vertical installation The empty slots mean that the one in question is not available Sandwich Panels – Fire resistance
