The «Mouton et Gueule de Loup» windows are particularly suited to the renovation of monumental and / or protected buildings, Haussmann style appartments or simply for the love of the vintage and authentic designs.

Composed by two wings:  the first one is made of a full half-round called “Mouton” – sheep.

The second wing has a recessed moulding that is described as a “Gueule de Loup” – wolf’s mouth.

When the window is closed, the moulding of the first sash, made of a solid half-round, fits into the moulding of the second hollowed sash.

This type of closure offers a significant advantage. It makes possible to create very large windows. It is ideal for Parisian homes with high ceilings.
