Any suggestions please for material for an access cover to be inserted in the downstairs ceiling?
Purpose is to provide very occasional service access to CH drain plugs & (possibly stop valves) at the lowest point the pipes run upstairs.
Needs to be 400mm across joists & 150mm wide (200mm would be better) & preferably finish flush with the existing 12mm plasterboard & not be too glaringly obvious when painted in white emulsion. I am envisaging fixing it within some sort of simple framework with plain stainless or brass screws.
Presumably it strictly requires something with a suitable fire rating
- would the MDF I used to cover the pipes going up the wall (as recommended in an earlier thread) be considered satisfactory?
TIA for any suggestions
