shingled wooden rope with panelling inside
The wooden rope was insulated inside and outside with wooden insulation boards
On the outside a shingle umbrella was used again. The panelling inside was replaced by sheetrock.
wooden windows with insulating glass and partly still laminated glass
In the existing building mainly softwood windows with a 110 mm frame were installed. These were replaced by IV 88 profiles in spruce.
The division of the existing windows and shutters has been retained.
MEASURES TO INCREASE AIRTIGHTNESS
The previous cold roof was removed and insulated.
From the outside, the roof shape was preserved. A loggia was only integrated into the attached new building section.
The basement ceiling was renewed. The existing building had a solid wooden ceiling with fill. During the renovation an insulated reinforced concrete ceiling was installed thus increasing the clear height on the ground floor.
The measure increased the residential value and is not visible from outside.
Windproof levels were installed and connected in the roof and wall structure.
