Insulation in timber frame stud wall that has a door in it

[Toomuchregulation]

Do the regulations allow a timber frame stud wall that has a door in it to be without insulation in the cavity between plasterboards. This is in a two bedroom house that is undergoing material alteration. Any reference to literature explaining loopholes to regulations would be appreciated.

The Handifoam swift rise foam insulation can it be used to fill the cavity of a timber frame stud wall that has been plastered - ie can it be injected into the wall and will this comply with building regulations for insulation in a plastered stud wall timber frame - in a 2 bedroom flat with living room and kitchen and bathroom. Any references to literature to building regulations and handifoam use would be appreciated.

Stud wall? Is this an internal partition wall? Or an outside wall with the warm house on one side and the cold hard world on the other?

It's an internal wall? Then why do you want to insulate it?

Building Control have asked for insulation throughout my flat but I was wondering if my wall has a door do the regulations allow a timber frame stud wall that has a door in it to be without insulation in the cavity between plasterboards. This is in a two bedroom house that is undergoing material alteration.
The internal wall is up so I need information to stop building Control forcing me to rip out the wall and put in insulation. If there is a door in the wall does it say anywhere that insulation in the wall around a door would not be required for both soundproofing and fireproofing. Cheers

If you haven't plastered yet, ask the building control inspector who's overseeing your work...some are even human
It's not that big a job to take off one side of plasterboard and refit at this stage if you have to and would be an advantage anyway (sound/heat, etc).

If you want to risk it, chances are he might never know, if he doesn't ask to see it specifically. But I can't see how, if they've asked for insulation throughout your flat, an internal wall would be exempt because it has a door in it, but maybe someone knows otherwise.

Still, each inspector will work their own way, so best to speak to yours, if they're already involved in the job.

My Building Inspector has it in for me nobody likes him in this Town - thanks for your answers I will ask another Building Control in another County to see if I get the easiest option from them - this inspector I have goes for the most expensive option every time - he loves his job. if anyone can help with regard to insulation matters in such a case that would be great. Thanks John and Noodlz for the interest time for bed I think if I can sleep. The wall has been plastered. All the best.

It's probably to meet requirements for soundproofing. You didn't mention what's gonna be on either side of this wall. If for example it divides a berdoom and bathroom then the walls need to meet a minimum rating for sound. After all, you don't want someone hearing your parps and gurgles when you're having a chat with messrs Armitage and Shanks.

12.5mm on 75mm stud is well below par without insulation.
