You can also buy FAKRO roof windows from us. These are modern roof windows that illuminate the interior, enable ventilation of the attic and provide us with a view outside the building. Installation of such windows in the roof is inexpensive. Roof windows are durable, safe, energy efficient and comfortable to operate. Standard pivot windows are the most commonly ordered windows, but they are more and more often being replaced by more modern pivot and tilt windows, which provide greater functionality.
