In addition to heat tracing and insulation work at a client's location, Isolatie Combinatie has also created obstructions for passageways and improved a generator exhaust. The obstructions are two passages between the wall and a tank, which are provided with coated steel plates. An obstruction has also been made for a cage ladder with a checker plate hatch which is fitted with a padlock. The obstructions ensure that no unwanted visitors can enter the objects. When adjusting the aggregate exhaust, it is placed in the correct direction and fitted with a stainless-steel bend with a prefabricated rain hat. In addition to new construction work, Isolatie Combinatie also provides repair and overhaul of metal constructions.
