We need help on fixing a stud wall on our garage.?

Question

We are converting our garage into a kitchen extension. It has a single brick wall at present, what gap should we leave between this and the stud wall we are putting up? Building regs will be inspecting it. They did tell me but I have forgotten.

Answer 1

Without knowing where you are, STUDS are relatively standard in the USA...between 1&1/2 to 1/5/8 thick, by 3&1/2 to 3& 5/8 wide, giving you an assumed DEPTH from an exterior wall to an interior wall of 3 & 5/8.

No offense at all, but I find it scarey that a wall is ONLY single brick thick?

Get the REGS. again. Typically there are fractional variations in milling.

Answer 2

Agree with Steve. You could also go straight up against a brick wall, but why do so. Cannot you incorporate it, or are you adding on an extension to the house? In any case, you should call building safety again since they will inspect the house and could tag you on incorrect design.
As for the air space between, I would do so. I would at minimim place 3/4" of either styrofoam insulation or some other type, but if you build a studded wall, you would have room in the 3 1/2" space for fiberglass insulation. Not insulating when you can just causes you heat and cold issues later. Would not worry about fire lanes if you insulate-- you do have a brick wall. Steve, they may have an older home with brick exterior, but some kind of plaster over lathe interior or perhaps even furring strips and drywall. Who knows?

Answer 3

Hmm, I'm not sure I understand exactly what you're asking, but you shouldn't have to leave any space between them. The only code I can think of is that untreated wood can't make direct contact with a cement product. That can be resolved by placing felt on the side of the stud in contact with the brick. This info. would be based on the 2004 standard building code.

Answer 4

On standard timber clad buildings, which is what you are producing requires a cavity space of at least 50mm from the internal to out.The spec would be as follows. 32mm insulation foil backed plasterboard fixed to 100mmx47mm vertical timber stud walling at .450mm centres with horizontal nogging timbers 50mm insulation slabs should be included into the cavity space. (Note that all wiring and any services should be in the stud walling space and fitted prior to the plasterboard being fixed. it would also be adviseable to include a set of horizontal noggings at the height of the proposed base and wall units).

Answer 5

If you want to start a woodworking project, you need all the necessary information, including schematics, blueprints, materials lists, dimensions etc. That is where Teds Woodworking comes in. The plans are clearly drawn and there're step-by-step explainations of how the plan should be done and put together. Go here https://tr.im/QzmLp

There are several other sites whose collection of plans have the dimensions totally wrong without any indication of parts lists, material lists or the tools needed. If you're one of those people who have bought plans like this in the past, Teds Woodworking will change your perception.

Answer 6

i recommend that you make sure that all the pointing is full on the bricks and put a damp proof membrane on the wall whether to seal it with bitumin waterproofer or (polythen sheet) and put dpc behind the timbers on the wall use 100x50 timbers and 50 -60 mm insulation board cut tight to and wedged in tight so that it will be tight to the foiled back plasterboard so that air can flow between insulation and out side skin... all depends on your situation!!!! the job could be done in a few different ways which would all comply to building regs

Answer 7

I believe what they are looking for is a dead air space to prevent moisture from occurring between the two different surfaces. this doesnt take much, an inch should do it. Also if you plan to insulate the new stud, And you use a Kraft paper faced insulation batt. Be sure to install the paper side to the new drywall side. If it is in the dead air space it is against bldg code and mfg. spec. for the insulation. The paper will burn in the air space but not if its flush to the drywall. Good luck..

Answer 8

Why does there need to be a gap at all???A gap between the wood and brick creates a space for cold air to get in and for fire to travel.Or maybe I'm not picturing this correctly.I've done this kinda work before and I dont recall ever leaving any kind of gap

Answer 9

Call the building dept and ask again. This is a very important step and you will eventually need to have the inspector see it again or sign off on it..don't make a costly mistake.

Answer 10

use a celcon insulation block
