About SIB Insulation
Over 30 years of experience in high-quality technical insulation.
Our History
Samenwerkend Isolatie Bedrijf (S.I.B.) was founded with a clear goal: providing the very best thermal insulation solutions for the industrial and maritime sectors. Under our own brand name Duratras® we have been producing and installing high-quality insulation mattresses for over 30 years.
With locations in Almere (headquarters) and Munnekezijl, we cover the whole of the Netherlands and beyond. Our strength lies in our flexible, experienced team of specialists who can measure, produce and install on location — even in the most complex situations.
Our approach
Every Duratras® insulation mattress is custom-made. We start by carefully measuring the pipes, fittings or appliances on site. The mattresses are then produced in our own factory and installed by our certified fitters. This process guarantees a perfect fit and maximum insulation performance.
Quality and Safety
SIB is a VCA* certified company. Safety, health, and the environment come first — both in our own factory and during installation at your location. Our fitters are fully trained and work with modern materials and tools. In case of emergencies, we can be on site within 3 hours.
