Batten sizes

[eandg]

Any reason I shouldn't use the following:

 

25*50 for counterbattening for timber cladding

25*50 for battening service void for electrics (backing boxes)

35*50 for battening service void for plumbing (22mm pipework)

 

Cheers.

Only consideration I can think of is if you need to insulate the pipes?

Spoke with plumber about this and he doesn't seem to think we will unless we're particularly anal about having very cold water instantaneously.

Depends on your runs. Ours takes a good 30 seconds to run cold. Might not feel like a lot of time but it soon gets frustrating.

Yup. I always spec a rising cold main at the kitchen sink, if the primary one rises in the plant room, so there’s no wait for raw, cold water.

My main concern was, if there were to be any hot returns they’d need insulating.

Only thing I would say about 35mm battens, with plumbing is there may not be enough room for pipe clips.

Don't use 35mm battens, just double up 25mm ones so you have 50mm. Also cheaper as you can order a big job lot of 25x50 and not risk running out and have less wastage.

This. We had to do the same around our water mains.

+1 also doubling makes getting the wall flat much easier when you overlap the joints
