A 25% opening is also 25% opening distributed over the entire surface of the window, compared to an unequal opening with coupled flaps. In this way there is no shadow formation on the house floor. This prevents the animals from standing close to each other due to daylight entry.
The length of the window can be made to fit between the purlins in any size. In this way, the space between the purlins can be used optimally. As a result, the net daylight area per roof window depends on the purlin spacing. As a result, as few roof windows as possible are required.
The benefit of suitable dimensions also saves a lot of mounting costs, because the roof windows can be mounted directly on the purlins. This avoids the extra labor that would be required when placing a frame around the roof windows.
Plug & play mounting
Due to the materials used, the roof windows are light in weight, which contributes to an easy installation.
