This would alter the internal character and I expect this would require some convincing before permission would be granted. Currently these are in-filled with plaster board up to ceiling height - I could continue this infill on the newly exposed roof using plaster board. no ceiling and continue the infill to sloping rafters up to the ridge beam. Option 3: leave the collars/joists exposed i.e. This would be classed as a change of material although not altering the character, but I expect the CO would see it as a heritage gain and I would anticipate getting approval for this subject to details on the materials, fixings, application and finished decoration. Option 2: lath and lime ceiling (there is evidence on the collars/ceiling joists that a lath and lime ceiling was installed at one time from the stripes on the wood - but that's just a point in time and not to say how it was originally constructed). Option 1: like-for-like repair - I could have a new plasterboard ceiling installed and skimmed in a weekend and it would be back to how it was previously. Now is a good time to consult the CO as I am not yet altering, but simply mid-repair and considering options. The existing and failed modern plasterboard ceiling was removed only after inspection to confirm and record the materials and checked with other rooms. Although I am confident that no criminal offence has taken place. Sorry about this lengthy response - I feel I need to explain more. this would be an edging plate between each rafter and at the height of the existing ceiling.Īs I say I have outlined my plans and options to the CO, but I'd like to get a view of what others have seen, done, recommend.
EXPOSED RAFTER CEILING INSTALL
Or should I try and install some kind of edging plate and leave the existing plasterboard intact below that edging plate and use lime and lath above. If I did go for lath and lime up in the rafters should I remove all the existing plasterboard and lath and lime it all down to the wall plate. not vertical studs! that when I come to plaster them the plaster wont form good nibs because the insulation effectively laying on the laths.ģ. Secondly I'm worried that the fact the rafters are at an angle i.e. But I'm worried all that oak lath up in the attic would cause the rafters to sag (even more). My preference would be to use something like wool for insulation because it is light and flexible and less nasty than fibre glass and easier to shape around the irregular rafters than kinspan. Would I be better using lath between the rafters rather than plasterboard and then use lime plaster. This would leave the ceiling joists exposed - I call them ceiling joists because the current ceiling are attached to them - but really I should probably call them collars - which is what I think their original purpose was.Ģ. Just use the same type of insulation (glass fibre between the roofing liner) and continue with infill plasterboard close to the ridge beam and infill panels either end of the room to close them off from the neighbouring room. Above the ceiling the rafters continue to rise up a further 4 feet until the ridge beam - so in other words a small loft space above the ceilings - I don't use any of it for storage - just water tanks above the bathroom. Then plasterboard between the rafters so they are exposed and that slope in and rise to a height of about 6 feet and to the plasterboard ceiling suspended on ceiling joists. The current configuration - walls rise up 2 feet from floor with exposed studs and wall plate infilled with plasterboard. Worse case I could simply whack up new plasterboard and effect a repair and move on if I don't get permission. I've reached out to the CO and asked their advice on my plans before filling in another LBC application form (the last one took 7 months to get processed and approved - not sure my teenage daughter, who's bedroom is most impacted, is going to wait that long). Now its all exposed I'm thinking I might try and leave it that way - looks nice. One bedroom ceiling was starting to come down - so I dismantled it before it fell.
The bedroom ceilings are low and not straight.
