Hi all,

I would like to share with everyone my efforts at internally insulating my little Cornish house.

I have been able to bring down U values on the walls from around 3 to 0.3.

The work has been invasive but worth the effort, the room has been very warm when cold this summer and cooler then other parts of the house when it has been hot.

I will add a bit more on the second room to which I have done in a slightly different way.

Comments are very welcome.

Nice work, well documented. Do I understand correctly that the party wall is just timber? - that seems unusual.

Hello Wokey,

Thanks.

You are correct the party wall is timber, its a house that was crudly split into two years back.

Not fun as next door is rented and although we get along fine they are looking to move out due to size constraints and so who knows for the new people.

Cheers

If you need to fit fire doors etc. to flat conversions, does this also mean that the partition wall must also be fireproof?

I would think this to be the case, But im not sure.

If you plaster board on the walls then that will be half hour, how long is a fire dorr rated for?

For domestic the recommendation is FD30 ie 30 minute rating.
Having been told by the installer of my wood burner, that the plasterboard behind it needed to be the fire-proof variety ie red in colour, very dense/heavy, extremely expensive, I duly installed it.  When I went to the manufacturers site for more data, it has the same 30 minute rating as ordinary plasterboard.  wackoold
