To meet specific demands when renovating buildings, where the respect towards existing traditional styles is essential, Stenfis has created the F57L window with an entirely wooden drip flap.

Its main features are the same as those of the F57 window, both in terms of construction and design: double sealing (upon request), between 10 and 12 closing points (depending on the type of sash), profile characterised by a more relevant bevel.

As for the F57 version, the F57L window with wooden drip flap can be equipped with the same type of hinges for both the ordinary and for the trapdoor version. This renders the window trendier and more pleasant to look at.

If the glass employed in the construction of both the F57 and F57L window is more performing than the glass used during the certification tests, it will be possible to improve all performance levels (thermal and acoustic insulation, jointing, etc.).

Obviously the F57L window is also certified.
