We use different types of external insulation, one of which allows us to install rinks on top of any underlying material. It is placed under the rink and thereby isolates the cold generated by the coils.
Isotir is great for closed environments such as shopping centres or sports venues, protecting all kinds of flooring.
Catramina is a waterproof membrane manufactured with an elastomeric compound (BPE), with -25°C/-13°F cold flexibility and is placed under the rink, thereby isolating the cold generated by the coils.
This product is also available in a version with DECOTEX treatment. This involves an application on the upper face of a special black polypropylenic tissue.
