Skylight roof windows for non-heated rooms:
It's up to you to decide whether you want your skylight to open to the left or upwards. But make sure they are positioned at no more than 90° in order to make sure you can open the skylight.
If you have tiles check the size of your opening - otherwise move to the next step
For questions contact a professional specialist. The opening should be 2 cm wider and higher than the skylight frame's outside dimensions. But beware! The maximum approved profile height for bricks mustn't exceed 90 mm.
If you have slate, check the size of your opening otherwise move to the next step
For questions please contact us or contact a specialist. The opening should be 2 cm wider and higher than the cold room skylight frame outside dimensions. When installing on a slate roof, remove the foam seal completely. Use a rubber mallet to hammer the aluminum elements flat.
A tile roof:
Ensure a 6-10 cm distance between the skylight and the first row of bricks above. Under the skylight you should have an 8 cm gap. A 3 cm gap is recommended each side.
If you have roof slates:
Ensure a 6-10 cm gap between the skylight and the first row of bricks. We recommend a 4.5 cm gap at the sides. Under the skylight, there should be an 8 cm gap.
Fixing the skylight to the rafters
Using a hammer and nails, attach the skylight to the rafters.
The last steps from the outside (if you have tiles):
After the roof hatch is mounted, you can replace the brick panels on the side. Ensure there is the minimum distance between the roof window and the first row / column bricks. This should be 6-10 cm on the top, and on the sides 3 cm. If the foam seal presses the bricks too far upwards, remove with a knife. Hand press the skirt close to the clay tiles under the skylight.
The last steps from the outside (if you have slate):
Now insert the slates on the bottom and side covers. Hand press the skirt close to the slate under the skylight.
You are done:
