All Perfectline profile lines are extruded exclusively on the base of zinc-calcic stabilisers. Therefore they don't contrain plumbic stabilizers.

1. Elegant line with the round shape of the sash Perfectline Oval series makes it suitable for any architectonic style.
2. Particularly low maintenance thanks to flat and smooth surfaces that don't need conservation.
3. Flat surface of the glazing bead make homogeneous surface with the sash.
4. The whole height of the frame and sash amounts to 118mm only, that makes the glass surfaces bigger, and in consequence provides more light to the inferior of the flat.
5. 5-chamber profile system assures the perfect heat insulation as well as noise protection.
6. Two seals of the oriented surfaces with the slope of 15 degres (the same that in case of the profiles) provide perfect protection against uncontrolled air exchange and excellently remove water.
7. Stable glass mounting in the profiles of the depth of 24mm makes the window more secure, more difficult to force by the burglars as well as allows to limit water-vapour condensation on the glass.
8. Possibility of using the whole range of glass panes of the thickness from 14 to 42mm without applying any other additional profiles.
9. 13mm axis of the fitting notch provides better anti-burglar protection.
10. The profiles with a basic overall depth of 70mm assures good resistance to atmosferic conditions.
11. Specially selected and calculated steel reinforcements assure good static properties and security.
12. Perfectline profiles allow to construct the window sashes of the width 1500mm without any other preservations.
