I live in a traditional Cotswold cottage, about 400 years old and yes. It's a cave - stuffy in summer and freezing in winter.

Sometimes I wonder if it would be more comfortable to just sleep in the garden. Looks pretty though.

You most certainly can. The thermal transfer properties of building materials is a known quantity and probably used in the EPC calculations. Your 2 feet of rock is pretty tulip at retaining heat.

"A typical 500mm thick stone wall, for example, has the equivalent insulating value of only 15mm of rockwool. In comparison, to pass building regs a new house in the UK needs the equivalent of 150-200mm of rockwool. The typical stone wall lets out about fourteen times as much heat as a wall in a new house. To meet UK building regs you’d have to make it seven meters thick."

damn you are confusing them with facts again!, darn Zeity beat me, where is a war criminal when you need them?

This is a house with 2 foot thick rubble walls and a thatched roof. Cant get better insulation than that .

Physics 101 was wasted on you. Rubble / stone no matter how thick is a terrible insulator while being an excellent conductor.

TBH People looking at that grossglocknerQUOTE=FrontEnder;2640419]reed the article, it explains this

I got to

But make sure you put the insulation on the outside and not the inside; otherwise you lose the effect of mass that will keep you cool in the summer. More on that later.

Then the article ended...

Is that supposed to be an issult?

reed the article, it explains this

Stop confusing us with the facts, Specifically in General.

[FrontEnder]

Certainly seems to work well the other way though.

It can be 90 degrees outside & coming inside is like stepping into a nice cool cave. No need for air con here.

read the article, it explains this

Just got one of these done & I'm in zone E.

Negative influencers, according to the guy who came out were no loft insulation and no cavity wall insulation.

Can only hope prospective purchasers don't pay any attention to them because they're clearly totally inaccurate unless you live in a modern Baratt style home.

Is it listed? If it is, you're stuck with what you have, and nobody looks at the EPC ratings anyway.

[Big Blue Plymouth]

TBH People looking at that style of home are not really the type who worry overmuch about the EPC rating

Yes, hope you're right.

They also used to mark you down if you had incandescent lightbulbs when the new fangled energy saving ones came out, which have been superseded by LED.

Yes, those ones that take 30 seconds to light up after you've switched them on. Just what you need on a dark Monday morning when you're in a rush and can't find your keys . I whipped those straight out when I moved in.

[ladymuck]

They are a bit crap. I look at them and go 'meh'.
