So a few years ago we had an Inotherm installed, and it is simply not worth the money. Thermal and acoustic insulation are already a joke. Now the inner glazing is broken because a dog ran into it (!), which in our case does not count as "use of force" and now, since the doors are pressed... we can throw them away completely. Warranty and goodwill are (of course!) foreign words to the Slovenians. THAT is really expensive, so despite the high costs we will install a Biffar again, like in the last house, which is definitely cheaper in the long run, you don’t hear anything from outside anymore and no glass breaks! The security technology with Inotherm is of course also brilliant, great frame, but what use is that if in an emergency someone can easily reach through the glass?
