conversion of a barn Sterpenich
The project was to transform this former barn into residential low energy. Using conventional chassis with high performance glazing, insulating the floor with polyurethane insulation and the roof with wood wool are not a problem. The heat insulation of facades, however, has been a long discussion: should focus on safeguarding the exterior frames visible (and insulate walls from the inside) or should it focus on lack of thermal bridging by insulating the exterior walls (and remove the stone frames)?
The solution was to isolate the exterior facades, using an EPS panel coated with a plaster. But to keep this house its classic look, dear to the Owner, it was decided to reconstruct the frames with a stucco imitating natural stone, applied to frames in EPS panels. Thermal bridges are thus minimized and the appearance of the facade saved.
This solution was implemented both in front than back cover.
thresholds of windows have been carved into the stone (stone Jaumont), with the overflow wanted to cover the 8 cm + plaster insulation. Uprights and lintels are covered a plaster imitation stone.
The transoms were "remade" identical, but with a continuous thermal insulation.
Ditto regarding the key vintage "1858". The debate is probably not confined to this type of intervention, but continued under the insulation, framing stones existing will return to a situation where the original way to reconcile the heritage and the energy needed in the future offer other solutions.
