Insulation

[Tony]

Hi Zednine,

I think the best way to resolve this is to start a small claim against the developer - you or one of your neeighbours can be the guinea pig. If successful the rest can follow suit. £35 to start a claim so the stakes are low, the risk is the develop will say that part L didn't apply wne planning was approved. I know others have tried this for other complaints - the important thing to remember is the claim has to be less than £5000.

Incidently, you ought to have at least 250mm of mineral wool loft insulation aside from the cavity wall issue. I work in the trade, and I tend to know more about lofts that cavity walls, but the same regulations apply to both. You can download a copy of the building regulations - at the government planning portal website (I would link it, but since this is my first post I can't). Look for Part L Approved Documents

It might be worth your while having a look around the site anyway, there might be something on there you can use.

Hope this helps

hi insulag

the problem with the building regs is that they just seem to say what the requirment is in tech talk...to the layman this is nonsense... i am in the building trade and i dont understand it..

Zednine, I have to admit the building regs are mostly technical babble, but most insulation manufacturers should give you the r-values or u-values you need to calculate the thicknesses required. I'm not sure I am allowed to do such a shameless plug, but I did specifically put a page on my website to try and help put some of this stuff into something approaching English... still slightly technical but I think it helps make some sense of it. I think you can get to the site by clicking on my user name, but if not Google "Insulation and Lagging" and we should pop up. Usually if you go to the manufacturers website they will have worked out already how much you need, if it is a lot then you probably know the material isn't so good. I highly recommend sticking with the bigger names with things like this, I know a lot of companies that basically make false claims because they know they will get away with it. I grew up around the insulation industry so I could probably list most of the main offenders... I just won't since I don't want to be sued
