Introducing our shearless solution for thermal deformationClick for product sheet
Dramatically reduce the bending in doors and windows
The superior solution
- Allows the inside and outside of the aluminum frame to expand at different rates without bending
- Easy to create different insulating strip geometries for greater design flexibility
- Symmetric profile allows for insertion in either direction
- Made from environmentally friendly polyamide 6.6
- Minimizes thermal conductivity to improve energy performance
- Assembles similar to our standard thermal barriers
How it works
- Polyamide thermal barrier designed to slide in one axis allowing outer and inner frame to expand independently
- Total flexibility in one direction leads to greatest results in bending reduction
What is thermal deformation and the bimetal effect?
Thermal deformation is the change in shape, area, and volume in response to temperature change. Aluminum doors, windows, and facades will enlarge when warm and contract when cold as far as they have space.
When exposed to direct sunlight, the outside aluminum frame will experience higher temperatures than the inside frame. This temperature difference of the two metal sections will cause the outside to expand more than the inside. This is known as the bimetal effect.
In doors, bending of the frame due to the bimetal effect creates high pressure between the deadbolt of the locking mechanism in the door leaf and the lock hatch in the frame, causing difficulty to open or close the door. The bimetal effect is even more prevalent in larger doors and systems installed in direct sunlight.
