Problems solved by technology

[0004] However, regulations in some countries state that a former attic must have an emergency exit or rescue opening if it is to be used as a residence
Although the skylight structure disclosed in EP 0 733 146 B1 can provide a larger opening for a predetermined size of the skylight, this opening can allow more people to escape or be rescued in an emergency, but this structure does not comply with the relevant rescue opening the strictest standard
In order to meet the above criteria, measures must be taken, either to provide a special rescue opening made for this purpose, or to use a skylight larger than said predetermined size, but this will at least increase the cost of converting a former attic into a dwelling , or cannot be achieved due to installation conditions
