Ireland and the UK have regulations which control all sorts of things in new homes. From security to fire to accessibility for the disabled, are controlled by these regulations. Part L (yes there are also Parts A-M) relates to the conservation of fuel and energy.
So… What does it have to say about insulation…
Well first of all look my post on U-Values
Then have a look at this pic…
So what’s interesting about that? Well have a look the number for a window, it 2, versus a wall, which is 0.27. The regulations for a window is a 7 times higher than a wall. So in a new house, it all about your windows… All about them…

Hello, What do you mean its all about windows. Windows let more heat out than walls, so what your saying is to get better insulated windows? or have smaller windows?
Sorry, I wasn’t clear. Heat wwill always escape through the weak point, so yes I do mean that smaller windows with better insulating properties is well worth investing in. I do accept that they are a relatively small area, but they are very much the weak point in most houses
