i can actually see the roof tiles from inside my loft with cement plugging the gaps - so there is no felt

i've not put much up there - just my bench and its sat by the chimney which is supporting some joists and over one of the stud walls - so its very well supported up there with all the extra supporting i have done.

its not a proper room - i have fitted a big loft hatch and just wanted to make it fairly warm in the winter with something to stop me getting a mouth full of 80 year old dust in me gob!

and maybe a couple of velux windows for the summer


stud wall might not be loadbearing in a house as old as yours but i'm not gonna tell you what to do i'm sure youve checked it out :y

always remember the tale one of our structural engineers told me, his friend used to keep his 'collection' in the loft, turns out he was a bit of an archeologist on the side and basicaly had a loft full of rocks :o :D :o

 It sounds like you are as well to go for Building Reg appro, you could go to all the work of putting in windows, only to get told to take them out again  :-X  

I am following BR in my current project, I nailed 1"sq batons 1" down on the rafters and am pushing about 2" insulation between the rafters up to the batton, hence the required gap, so I only need a further 2" screwed below to meet requirements. I was lucky and got some 2"  insulation with plasterboard bonded from Seconds and Co for a very good price, so I just screw this lot up, get it skimmed and that's it.

I found the Building Control Dept in Bradford very helpful, I took lots of photos during each stage of the insulation process, and when I went to see the inspector for the half way thro checkup, I showed him the photos, and he was happy enough with what he saw to say "just proceed, no need for a site visit"  :y  Also when you come to sell the house, you can show the photos to any HIPs person to prove it meets BR standards  :y

Yes, or made of some use................... No, that would require thinking by civil servants, which is too much to ask.

The current HIP's dont cover anything like this at all, they are only interested in insulation values and then its only what they can see.

They are an absolute waste of time, money and paper!

Interestingly, you can board, insulate and fit velux windows into a roof without building regs........its when it becomes an inhabited room with permanent access (i.e. stairs rather than a removable ladder) that building regs are required.

That's useful to know. I have such a loft - boarded and insulated by the previous owner and wondered what red tape would be involved in a couple of velux windows. Access is by loft hatch and ladder. I suspect I would have to rip it out and start again to meet building regs - that's not going to happen.

The planning exemption for dormer windows in a loft is here on page 12:

A mate of mine is an architect  and surveyor and he also reckons they're a total choccy teapot and something his profession were dead against. As usual with our nannying government, they knew best and ignored the advice of the professionals.  >:(

Well, it's made of paper. Most paperwork has at least one useful purpose, and only occasionally more than one. Andrex it might not be, I grant you, but....

No slaters felt so you really must provide some eaves to ridge or eaves to eaves ventilation.

kingspan insulation in between the rafters, plasterboard then just tape and joint it, job will only take a couple of days in all.
