Hello everyone.
I am planning to purchase an existing property, built in 1960, in the Lower Rhine region.
The concepts from renovation consultants range from 16cm external wall insulation all around plus new triple glazing and a complete heating system to "for now just insulate the roof, tackle thermal bridges, and get moisture in the basement under control."
As a layperson, I look completely clueless...
I want to renovate as ecologically as possible, i.e., change as little as possible, as much as necessary, and use as little plastic and toxic materials as possible. Besides, I basically like the existing structure (33cm exterior wall: plaster, hollow block brick, plaster, solid clinker brick).
The detached single-story, fully cellar basement single-family house has just under 140m2 of living space, half of which is under the roof. The basement and attic are initially unoccupied.
The oil central heating is from Viessmann, built in 1975, with 3 plastic tanks of 1500 l each.
The radiators are gravity-flow and from the construction year, like all other technical equipment. These will certainly need to be replaced.
The tile-covered roof is insulated with mineral wool. I don’t know the exact details yet. Due to an overhanging upper floor ceiling and a loggia facing south, several thermal bridges are present. The wooden windows are mostly from the construction year and single-glazed. In the upper floor, some new windows with insulated glass from 1993.
The basement shows partially swelling plaster and flaking paint above the skirting boards on the exterior walls. These were supposedly protected against penetrating moisture by mining activities (which were active there) around 15 years ago using bitumen mats or coatings as a precautionary measure throughout the entire settlement.
The surveyor suspects moisture transport in the plaster on the inner exterior walls and recommends an "extension" of the horizontal barrier at the height of the skirting boards beyond the plaster layer.
My idea of renovation would be to combat the thermal bridges, install new windows with max. double glazing (in coordination with the exterior wall’s k-value), and a new heating system. Possibly new insulation of the roof with cellulose or similar, if the current insulation is insufficient.
Does that make sense?
Which type of heating supported by a wood stove in the living room (already there, but open and without a water jacket) would be recommended?
By the way, the floors will mostly be real wood parquet and tiles in the bathrooms, kitchen, and hallway. The bathrooms will probably also be new, unfortunately, and are also from the 60s.
Either stick with oil and use a modern condensing boiler or throw everything including tanks out and work, for example, with radiant heaters?
That’s my idea as a layperson (I’ve bought the "Building in Existing Structures - Atlas").
I would gladly have a paid consultation on site. However, only if someone really knows what they’re doing and does not just present insulation value calculations...
THANKS in advance!
