The GUILLOTINE window slides vertically and also offers a large possibility of ventilation. Useful and safe for windows overlooking for example a balcony or a terrace without risk of injury on the shutter on the outside. Today the window is designed to move the panels vertically in addition to pivoting and to facilitate cleaning, like the sliding window. It exists in single or double version. The double version allows hot air to exit from the top while fresh air circulates in the lower opening.

The SLIDING window is a window with single or double horizontal sliding panels that has been used a lot in Quebec. It offers a quality of vision outwards without obstruction. This type of opening allows maximum air entry, and all at a low price. Today, the sliding panels are made of thermally sealed glass like any other type of window and are fitted with a latch system used to remove the panels for easier cleaning. This option is quite common in more recent constructions, because it allows you to open the window halfway for ventilation. Sliding windows are a great simple option, easy to open and easy to maintain.
