Choose from a painted plaster finish or timber/PVC-u cladding, with optional Fakro roof windows.
The more popular internal ceiling finish on most sunrooms would be the plasterboard painted white. The smooth white finish of interior plaster board reflects light inside the conservatory, maximising its brightness by allowing as much light to be bounced around the room as possible. This finish would be the ideal solution in the case of a conservatory roof replacement as you have become so used to the amount of light from your glass or polycarbonate roof the white finish will go somewhat to bringing the light back into your home.
For naturally bright rooms, the Timber finish could be the perfect choice for your conservatory ceiling. Timber has a warm appearance and wood panelling can give a softer more relaxed finish to the interior of your conservatory. Depending on the design and layout of your property, this finish could provide a clean and bright room whilst tying in aesthetically with the existing finish of your home and complimenting its garden surrounding.
