Are the wooden slats, nailed to the top and the bottom of the skylight, supposed to be removed before installation?
Yes. The purpose of nailing the slats is for product protection purposes only. All the slats should be removed before installation, but it is recommended to remove them just before placing the skylight or roof window in the prepared opening in the roof.

How to prevent from condensation?
The moisture put into the air from a typical family is similar to emptying a large bucket of water on the floor every day. Kitchens and bathrooms are areas where the build-up of condensation is especially high due to the steam produced from showering and cooking. Velux Opening Skylights act as extractors of hot air and minimize condensation and mould growth.
When condensation forms on the glazing of our windows, you should take it as a warning sign that you should ventilate more often. Regular ventilation is the most efficient way of preventing condensation water from forming on your window glazing. You can limit the amount of humidity as follows: If possible, do not dry your laundry inside the house. Close the doors of kitchens and bathrooms. Ventilate regularly for five minutes at least three or four times a day and, if possible, maintain a constant room temperature.
