I am trying to improve the EPC of an old house,
It has a cellar. I am thinking of applying Kingspan/Celotex between the joists beneath the ground floor.

Reply to Improving EPC. Floor InsulationInsulating the floor well won't make a huge difference to your score, maybe 4 or 5 points if that.
50mm kingspan has the insulating value of 150mm of rockwool.
The first 100mm of rockwool does around 98% of the insulating (it is not linear).
So you'll achieve as good a score (or almost)...16-05-2019, 15:29 PM -

Reply to Improving EPC. Floor InsulationWe insulated all the floors and some of the walls and the EPC surveyor said he couldn't take it into account for the EPC because he couldn't see it.
Be sure to speak to your assessor before hand to make arrangements for him to see the insulation.11-05-2019, 19:21 PM -

The plasterer who was supposed to be doing it has not turned up.
I may try to do it myself.
In France they have a brilliant product called "Crepe" which is pure white and you put it on walls with a plasterers trowel....27-04-2019, 09:30 AM -
Reply to Improving WallsCould you board it out? I plastered a chimney breast - oh yes I did! - and it was a lot easier that I thought. I sanded it then wallpapered it and it's fab
In another room I used that ready mixed stuff that you cover artex with and that worked well too....

Reply to Improving WallsThere are a couple of U Tube vids of similar but it does not seem available in the UK.
Sanding anything over a large area creates a lot of dust and mess - I'd go for the plasterer everytime.29-04-2019, 08:03 AM -
I have a flat with umpteen 12 volt 50W downlights and umpteen electronic transformers in the ceiling above them. The bulbs often seem to burn out the transformer when the bulbs blow. Anyone found a solution to this?22-04-2019, 17:12 PM
