Shear-free: the insulating profile for doors | Insulbar
Ensinger has a new solution to the well-known problem encountered with thermally separated metal doors, the bi-temperature effect (also known as the bi-metal effect). Above all in front doors situated on the sunny side of the building, the outer aluminium shell expands significantly when it heats up. As a result of the temperature difference between this and the inner shell, the entire assembly bulges outwards. The door becomes deformed and, at worst, can no longer be opened or closed. This effect is amplified when the door is painted in a dark colour, as the surface gets particularly hot.
All the benefits at a glance
- Shear-free, consequently a more significance minimisation of the bi-temperature effect compared to shear-weak and shear-resistant profiles
- Minimal shear rigidity c and low shear strength T
- Optimised geometry for high transverse tensile strength Q
- Can be rolled up and laminated like a conventional insulating profile
