Belcaldo PUR is a flexible insulation made of melamine resin. The thickness of the insulation is variable. Depending on the hot water tank dimensions, the insulation consists of one or more parts. The segments are joined together by hook fasteners.

Additionally, Belcaldo PUR is provided with cuneiform incisions in order to maintain the flexibility of the insulation. Consequently, the insulation matches the tank optimally allowing excellent heat sealing and energy cost reduction.

The melamine resin insulation or Basotect foam is said to be fire retardant, having the fire class B1 based on DIN 4102. Furthermore, the insulation is very light-weight and flexible, thus easy to handle, to store and to install on existing insulations.

A 1mm thick outer layer of impact resistant PURtec PS with a textured finish is bonded to the melamine resin foam for strength. The lid consists of a Basotect layer which is covered with a thermoformed lid. Installing Belcaldo PUR on an existing unit is a standard feature. Cut outs for the plumbing connections are possible in the joint face. Beldcaldo insulations are 100% recyclable.
