External Wall Insulation
Site investigations confirmed that the existing external wall construction comprised featheredge boarding on c.100x50 s/w studs with lath and plaster finish internally, The plaster finish had been covered with hardboard panels with s/w battens over panel joints. No insulation has been found in the external wall construction. Removal of some hardboard panels has revealed that the lath and plaster is generally in very poor condition and needing to be replaced.
The specification for repair of the external walls is intended to allow the incorporation natural materials including a breather paper under the timber, insulation between existing studs and a lime plaster finish internally.
Internally: Lath and plaster was removed and replaced by woodwool boards fixed to existing studs, finished with lime plaster, 75mm thick thermafleece insulation slabs were fitted in the space between studs.
Site investigations confirmed that there is no insulation in the areas of sloping ceilings. A small amount of insulation [c.50mm thick] had been laid over the ceiling joists in the roof space. The ceiling areas finished internally in lath and plaster covered with a textured/painted paper are generally in poor condition.
The proposed alterations respected the history of this listed building. No major interventions were proposed and all materials where appropriate matched those existing.
