Stupid Timber Cladding Questions


Tin Soldier

Recommended Posts

So some stupid timber cladding questions, before I start planning how I'm going to attack this - my focus has been entirely elsewhere for months.

I have circa 50m2 of Vertical Board on Board Cladding to do.

 

Roof is on, slated etc.

Temporary fascias in place to give kick for slate etc, but does need replaced.

No barge boards and/or soffits in place yet- plan is to minimise the barge board/fascia/box end to the absolute minimum

 

 

Plan for cladding is vertical, and horizontal cross battening out, before board on board cladding is installed.

 

so, stupid questions in order.

 

1. Do I need to figure out and install fascia soffit, barge board, box bloody end etc first, and install. Then clad up to it or, clad first and install fascia/soffit over the top.

2. What can i use for a flashing/drip detail at top of window. This doesn't seem to be on the plans architect supplied, so I've missed it out. I've been looking around and timber cladding builds and some dont appear to have anything above window, other than timber detailing? 

3. does anyone have any decent links to videos of timber cladding detailing/installation - I've not really found anything that goes into detail about cladding round doors and windows.

I’m cladding to finish just above there the soffit goes. My reasoning is that I’ll have a nice clean edge that is easier to cut in the soffit board rather than the cladding.

 

Ive used DPC as the flashing over windows and doors, this is stapled and the taped into place over the breather membrane.

 

Let me know if you find any decent videos!

That's really lovely lizzie

 

Mine will be a little more rustic, whether I like it or not

 

Another question

 

I've decided how I will be affixing the larch barge board, question is how close do I put it to the bottom of the slates?

 

They currently overhand a few inches, I intend to but the larch right up to them, subject to someone telling me what I should put in between barge board and the slates or that I should leave a small gap?

Here’s my detail. Roofing company have suggested that I move the fascia board up by 50mm so that it aligns with the batten and counter batten.  Note the requirement for a fascia vent - Manthorpe  over fascia vent below

attaching face fix larch cladding - screws or nails?

 

You need to use stainless, whichever you choose.

 

We attached our horizontal larch using stainless nails. I discussed power-nailing with the guys who did it and they thought it wouldn't work due to the hardness of the larch. They pre-drilled every hole and then hand-nailed - a lot of work!

 

For our soffits, I've been using good quality (Spax) stainless screws and they work a treat. I was worried they'd need pre-drilling, but they go straight in with little effort and no splitting. Torx heads help. One nice thing about screws is that if you need access at a later date, it's easy to do. I had to remove a bit of nailed cladding and it was a nightmare.

 

The battens for the horizontal cladding were power-nailed with galvanised nails. For the battens for the soffits, I just used Spax screws (longer than for the cladding) and they've been fine, although not much is being asked of them in terms of loads.

I used stainless steel ring shank nails on my larch  cladding as there is a lot of pressure / movement  on the fixings when using unseasoned timber in this style as it dries and tries to warp. I had no problems at all and 4 years on nothing has failed. I pre drilled all the holes and again have had no splitting or cracking.

I used screws for the battens, mainly because of the length involved. A 50mm batten on top of a 50mm counter batten, then through the osb sheathing, and finally into the stud- it's a long way. You can't get nails that long, and even if you could, you wouldn't know whether you had hit the stud or not.

 

For the larch, I used stainless 70mm nails in a coil nailer. This has several advantages over a stick nailer: longer between refills, cheaper nails with no gas to buy, and most importantly nice full round heads on them. These look much better than the D-shaped clipped heads on a stick nailer, and you don't get the imprint of the hammer, because none of it protrudes past the egde of the nail head.

I didn't pre-drill except for nails within say two inches of the end of a board- for these I pre-drilled and hand nailed.

Holy Moly the price of stainless steel fixings.. I simply cannot believe it, I need circa 2000 of them - face fixed

 

Is there any reason deck screws cannot be used?

can coated screws (ugly green things) be used on the boards behind - that are unseen
