1. 18 mm tubular profile, the most streamlined in its class.
2. Extra deep (65-72 mm) to accommodate high-performance glazing.
3. 22 mm top supporting surface. If the window or door is being fitted in a subframe, the 22 mm top supporting surface helps hide the inevitable crack that forms on the edge of the plaster.
4. Innovative insulation system.
5. Ease of welding critical corner (“clean” edge, with no recesses that are difficult to weld).
6. Frame seal with vulcanized corners, providing extremely good weatherproofing to protect against water, air and wind.
7. Glazing seal vulcanized corners, hermetic seal on glass pane.
8. Option of making frame and hinged sash with same profile.
9. Gap between doors increased to 15 mm, allowing optimal rotation even when doors are very narrow.
10. Option of altering gap between profiles without ugly changes in the visible seal surface.
11. Safety tilt and turn hardware with “anti-condensation” system.
12. Etched marking to locate hardware fastening axis.
13. Resistance to weather conditions from 5 to 8 times higher than a common carbon steel.
14. Yield stress of 350Mpa, comparing with 235Mpa of carbon steel.
