How long does it take to install a roof window?
Approximately 40 minutes if you are a professional and have the correct installation accessories.
Installation accessories?
Yes, a lot of producers have additional installation accessories like the underfelt foil collar,
which reduces the amount of work that you need to put into proper roof preparation.
It is just that these accessories are expensive and thus not very popular.
We have decided to provide it free of charge for most Dakea windows. We want to make things easier and more comfortable for the professionals.
How does it work?
It is made of stretchable, highly tear-resistant polystyrene, non-woven fabric with a vapour permeable polyurethane coating.
It speeds up installation significantly as you do not need to cut the foil and make the underfelt foil collar from pieces.
It also makes your work safer due to its anti-slip coating.
Do you still need any other foil to ensure water tightness of the construction?
No, the Quick Install underfelt foil collar is made from one piece with no joints, so it ensures 100% water tightness.
It is a technically advanced product designed to protect the roof and tightness of the construction.
What about fire resistance?
It is highly fire resistant, ranked B1 in accordance with DIN 4102
and has an increased temperature tolerance of -40°C to +80°C.
