I need tips on
How to get rid of cold floors and drafts?
Risks of installing waterborne floor heating on wooden joists over a crawl space.
I have had a house for a year that was built in several stages between around 1930 and 1966.
Half of the house, kitchen, hall, and bathroom, has a crawl space with an old, stone-lined pantry underneath.
All the walls of the house are additionally insulated.
During this winter, the floor in this part of the house has been cold and drafty.
Especially near one of the outer walls in the kitchen.
I have removed part of the inner floor in the kitchen (not at the outer wall but more inside the house.)
And then I see that the original insulation, sawdust, has settled, leaving about a 2 cm gap between the insulation and the inner floor.
Can this gap cause the floor to be cold or does it not matter?
Can the cold floor and draft be remedied by removing the sawdust and filling with something like Icell up to the inner floor? Is there anything else that can be done, for example, some "cold stop" at the outer walls?
What are the risks of installing waterborne floor heating in this part of the house? (geothermal heating in the house.) Crawl space and wooden joists, is there a risk of moisture migration?
What measures should be taken with the subfloor before installing waterborne floor heating on wooden joists?
