Thermodul is a flexible insulation made of rigid EPTS or EPS foam. The thickness of the insulation is variable. Depending on the hot water tank dimensions, the insulation consists of one or more parts. The insulations consisting of one or more segments are joined together by hook fasteners.

Additionally, the Thermodul Insulation 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 Thermodul plus variant provides additionally a pressure activated glue, which guarantees an optimal fixation after about 30 seconds. This also provides a one man assembling due to its half shells form.  

The Thermodul rigid insulation is said to be fire retardant, having the fire class B1 based on DIN 4102. 

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