We often get asked about how to install our sashless windows as these widows have flush infills all the way around the inner frame.
Below is a cross section of the jamb and head fixing detail in a commercial double-glazed frame. Note that the fixing adaptor you are using may be different to what is shown as we offer several fixing adaptor options. To fix off the jamb, we recommend that you drill a hole (slightly bigger than the fixing) through the flush infill. This hole will be covered once the sashless team comes to fit the sashless insert.
More care needs to be taken when fixing off the head as the sashless insert does not fully cover the flush filler. The head fixing must be counter sunk and at the position shown below. Again, this fixing will be covered by the sashless insert. We do not recommend putting a fixing through the sill as this can cause water issues.
