Guide to chose the panel The cold rooms and rooms for conservation and storage of foods can be so called positive and negative. Generally the first ones with temperatures till -1 C and the second ones till -25 C. Depending on the temperature to maintain inside the room, a certain type of joint should be used : Appropriate for rooms with temperatures temperatures not below to +4 C, for the conservation of foods where a major temperature change does not require an adequate airtightness. Appropriate for rooms where foods are processed, maintaining the temperature till -1 C, where a major temperature change does not require an adequate airtightness Appropriate for rooms where finished products are stored; the temperature is not below to -8 C. These rooms must be well insulated and a greater airtightness is required, thanks to an adequate joint. rticularly adapted for rooms where frozen products are stored with temperatures till -28 C and rooms that impose constraining requirements in terms of minimisation of thermal bridges and air permeability. NOTA: These indications are just a suggestion for use. The designer has to choose the joint, the panel thickness and the other parameters of the Isopan commercial offer, depending on the performances required by the cold room 13
Dry joint The dry joint solution is economically the most profitable as it does not require any processing on site; the Isofrigo panel, in fact, is already equipped with PVC gaskets and this speeds up the assembly phase. 1 2 3 1.

Joint with thermo-expanding tape The joint with thermo-expanding tape offers a good airtightness. Thanks to the two thermo-expanding tapes, the capacity to prevent air flow between the inner and outer wall is increased. 1 2 3 4 1. Insulating core 2. Profiled sheet 3. Standard gasket 4.

Joint with expanding thixotropic sealant The airtightness is excellent, thanks to the lack of cracks guaranteed by the expanding sealant, whose thixotropic characteristic offers an excellent airtightness without impacting on the assembly easiness. A major advantage of the system is its cost advantage, to make it more worthwhile than the foamed joint solution, because there is less material used and the installation is faster. 1 2 3 4 1.

Foamed joint This is the basic solution of the foamed joint type. Thanks to the lack of cracks and the use of PVC gaskets under the plates, an optimal airtightness is obtained and consequently all thermal bridges caused by the joints are eliminated. 2 7 1 6 3 4 5 1.
