1. 18 mm tubular profile, the most streamlined in its class. The special shape of the profile means extremely high moments of inertia are achieved.
2. Extra deep profile (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. Oversize glazing bead, greater overlap of glass pane.
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. Special self-tapping glazing fastening screws.
14. Snap-in glazing retainer with “sharp edge” to increase resistance to wrenching.
