Bending Profiles with Polyamide Strips
In our modern era of sleek, clean materials, aluminium has taken the lead in making high quality windows, doors, and facades. The non-corrosive nature of aluminium along with its wide range of design options makes it the perfect materiel for this purpose.
The major downside of aluminium in this use is its great thermal conductivity.
Windows and doors are our thinnest connection to the outside and the highly conductive frames lead to thermal leaks.
The best solution to this problem is a thermal break, a polyamide strip used to create an insulated break in the metal.
Challenges to Aluminium Bending with a Thermal Break
Naturally, different materials have different properties when bending. Adding a thermal break into an aluminium section can cause a number of issues during the bending process.
The different material properties often mean different approaches are necessary. Methods that would usually be fine on a single aluminium sections may cause permanent damage to the plastic thermal inserts if not taken into consideration.
Common Issues that can arise are:
- Limitations to heat treatment options.
- Specialist Welding techniques required to preserve polyamide.
We can bend almost any section with a thermal break. Including the very widest sections used for solar shading and louvres.
