Hi I have a 1914 house in the Peak District .
I am currently renovating the house and am looking for advice regarding insulating the ground floor
Half of the ground floor has a concrete screed floor with no insulation under it
The other half is floor boards with a 4 ft void below.
The house is built on bed rock limestone not clay, soil
I am wanting ideas on how I can insulate the ground floor . I do not want to dig out the concrete floor and am looking at products to place on top of the existing screed. Obviously anything added to concrete will result in a step at one point where the back meets the front of the house
Also would it be possible to incorporate under floor heating to both concrete and timber floor?
I was going to insulate under the timber floor with rock wool or similar but am worried about restricting air circulation to the floor joists and causing further problems.
I look forward to hearing your ideas
