a. HC: Some Notes on Construction
HC is dry lined along every external wall. Most of the exterior walls are 2-3ft thick and constructed of local stone with sandstone reveals around the windows & doors, all bound with lime-mortar. On the interior of these walls, a wooden frame was constructed. The space between the wooden frame & walls was filled with 100-200mm thick mineral wool insulation. The whole frame was covered with a vapour-barrier, then 12mm plasterboard was applied. The vapour barrier stops the warm internal moisture-laden air penetrating the cavity and evaporating against the cold exterior wall. Some moisture-laden air may reach the cavity, but the mineral wool insulation will allow some evaporation, and the lime-mortar helps to move moisture from inside the wall to the exterior where it evaporates.

b. Main Bedroom (Bedroom 1) & En Suite: Some Notes on Flooring Structure
The main bedroom & en suite bathroom floors are of timber construction sitting on 2 layers of polyurethane insulation which in turn sit on a concrete slab that has been waterproofed with the high performance liquid damp-proof membrane “Synthaprufe” – making the concrete floor impervious to water & water vapour. The concrete slab floor continues through to the timber store/workshop. We were unsure if the bedroom concrete floor had been damp-proofed. There was no evidence at all of any damp in the floor, but, rather than dig up some concrete to confirm (which may have damaged any existing DPM), it was decided instead to coat the concrete with Synthaprufe. On top of the concrete floor, 2 layers of specialist polyurethane insulation from Sheffield Insulation were laid. The joins in the insulation were taped, with the joins of the two layers staggered. CaberFloor high density, high performance flooring panels were laid on top of this. The result is that the top surface of the wooden floor is approximately 70mm above the concrete floor.

c. Some Notes on Flooring Structure in Other Areas
Hall, Lounge & all Upper Level Flooring:
The original floorboards remain in place under all carpeted areas.

Kitchen Floor:
Almost certain the construction of the kitchen floor is exactly the same as the main bedroom, as detailed in paragraph b above. In addition, a layer of combination foam underlay is laid beneath the current laminate flooring.
