Ciella, established in the Laurentians, has 20 years of experience in the skylight and sun tunnel world. We offer installation, replacement and sales as well as repairing skylights for residential or commercial use.

Domed skylights

Montreal buildings often have pyramid skylights, which were installed years ago and have single pane glass. It was then necessary to install extra panes on the ceiling to save heat. Replacing them with updated products can significantly reduce your heat loss and save on heating costs while maximizing your comfort.

Heat and multi-storey buildings

Venting skylights can help regulate heat in high staircases. With a natural pleasant breeze, they can also have automatic closing systems in case of rain.
