I live on the ground floor of a block of flats (apartments) in London, UK. Below me (basement / -1 level) is the block’s communal boiler providing hot water for the taps and hot water for the radiators in each flat.
Unfortunately my flat gets hotter than I would like. I rarely use the radiators and make the educated guess that it is heat rising from the equipment downstairs conducting through the floor (concrete slab / screed etc.). To illustrate I have record temperatures of 12 degrees Celsius / 45 Fahrenheit outside whilst 26 degrees / 79 Fahrenheit inside my flat with radiators off. I am trying to address the issue at source with the block’s owners / management however a year on little movement.
As part of renovating the flat I am replacing flooring with an engineered wood floor. It feels that I may as well try and add some thermal insulation whilst doing so.
On this forum I have seen someone refer to insulation in issues of conduction being most effective when between the heat source and the conductive material / layer. In this instance this would be to insulate the ceiling downstairs in the boiler room. There is already some insulation down there and I will continue to press the issue for a more / better insulation.
However, I would be interested in opinions on if it is worth me insulating my side?
I will use a damp proof layer / vapour layer between the insulation and the chipboard / engineered wood floor.
One concern I have is could it make the heat issue worse in my flat?
