Vertical Tongue & Groove Timber Cladding Detail

[ultramods]

Can anyone please tell me how I should detail the bottom of the vertical timber cladding where it meets the top of the ground floor window please?

 

In the diagram below the red timber cladding is the only part that is not currently in position on the house.

 

I am wondering if the current detailing that i have specified in the diagram below might look odd at the bottom/end as the T&G profile will be visible.

 

Could I position the timber cladding flush with the ground floor window or could this cause potential issues with water ingress?

I’m not absolutely clear on what the issue is but if I have it right its the gap between first and second floor windows?

 

I’m single storey but think the same priciples apply.

 

At the top I have a metal header to match the windows and the vertical cladding comes down flush to that,  have a matching piece of cladding across sitting under the header to make it look neat.  At the bottom it is just cut off in a straight line all around and sits off the griund.

you will need something to create a "drip" otherwise all the water running down the cladding will just run down the window below

I think in example A it is likely that water would be drawn in under the bottom of the cladding.  I guess you can't seal it as you need to get airflow behind the cladding.  Does the manufacturer not specify how it should be detailed?

You should have vertical battens fixed to the timber frame studs, then horizontal battens on top to help create air flow behind the cladding.

 

A is better in your example as you need to make sure any water is directed away from the window head..

what stops the bugs and wasps making home behind the cladding?

should there not be some sort of screen at bottom of cladding ,which could also act as drip rail?

sure someone will comment

@scottishjohn I have insect mesh fixed behind my cladding

A fly screen mesh is recommended, although if there is sufficient ventilation up through the cladding it does not provide a good environment for bugs and flies.

@lizzie Nice cladding, what make and colour is it?

 

Also do you have more photos showing a whole wall of cladding?

 

I'm interested in the trim detail you have at ground level, what’s it covering up, what’s the trim made of ?

@Triassic thank you.  It's Siberian Larch and I got it from Vincent Timber.  It's a French product Sivalbp and Vincent are the sole supplier in UK. Mine was factory pre coated in new Age Gris It's a sacrificial coating which hopefully means I shouldn't get any uneven weathering.  http://www.vincenttimber.co.uk/products/sivalbp/index.html  It's very good quality cladding.

 

The trim at ground level a custom fabricated cover in powder coated aluminium.  Think a few have picked up on this trim now.  It's very smart and easy to fit over the edge of the slab.  Local fabricators did ours, they came out and measured up.  I had it coated to match windows. Same company did the heads for over the windows.

That is ... sharp.

Hi @lizzie. Agreed that is sharp. You may have mentioned elsewhere but what material did you use for your soffit/eaves? I can't really tell but it looks smart and matches with the windows and other trim well.

Thanks @LeeVanCleef Our soffit is a hardwood ply. We did the fascia in that too and painted it to match the roof colour (ral7012 which is a lead grey...specified by planning). Our windows and trims are 7016 as I didnt want the lighter colour I wanted a contrast so everything below the roof/fascia/soffit is 7016 and everything above is 7012.  We finally got around to finishing our fascias with the pc ali cladding this summer.  Was a much bigger job than anticipated as I wanted secret fix. Pleased with it. Finishing the landscaping is this summers job.
