Good evening dear construction fans,
a technical and cost-related issue has arisen for us.
We want (actually) ceiling-height windows. These are to be shaded with [Raffstore]. We were explained that we either need a frame extension (15cm) at the top. This already costs about 5,000 euros gross for all windows. Or (small) lintels have to be built.
The explanation is that the actual window frame cannot sit directly on the concrete ceiling, otherwise there would be problems with thermal insulation, since the [Raffstore] box basically sits at the height of the concrete thickness and thereby the space for the insulation (we use [WDVS]) would be lost.
In order not to see the frame extension or the small lintel, it is recommended to install a suspended ceiling.
Has anyone already heard of a similar issue or can anyone say something about it? Especially of course homeowners with ceiling-high windows with [Raffstore].
Thanks!
