Cover flashing

[Plupp 405730]

And we're still waiting for a picture of what you consider to be incorrectly done🤔

There you go! For those of us who want to help, it’s interesting but apparently not for her as long as she can badmouth the craftsman and his attitude towards her. It would be fun to hear the craftsman's side, I'm convinced that their stories do not match🙈

I haven't said that I am a trained carpenter. If I were, I wouldn't be asking what I believe are knowledgeable people about how things should be done. But when there is constant sighing and grumbling about everything that needs to be done, and things are presented in a condescending manner, I get annoyed. If someone explains that something can't be done that way because... That's completely okay. Maybe you should study management techniques a bit but definitely not emulate them. Then maybe you would understand. When I point out that he hasn't made a threshold but rather just a pile of plaster under the door and he sighs and says, "How do you think I should solve that?" It's incredibly unprofessional. Two closet doors hit the floor because he was in a hurry. I can't be bothered to argue about it, so I'll just put spacers under the hinges instead. A stick lies loose. It was never fastened.

But what does writing about it here solve? Wouldn't it be better to end the collaboration and find someone else who can do it so you're satisfied?

I'm having a discussion with my carpenter about how the flashing should be installed. We are not entirely in agreement. Is there anyone here who is a tinsmith who can show pictures of how it should look? Wood paneling

It seems like you have a serious carpenter.

In a façade, it's the wind barrier or equivalent that makes the wall seal. The façade itself is just an outer protection against sun, rain, and wind that takes most of the rain, but it's the wind barrier that should be 100% sealed and therefore some moisture and water can flow on it.

That's why I always install the ÖB inside the wind barrier so that water can flow correctly. It requires some skill and precision, yes. My method is then to tape the wind barrier to the metal so that water can't blow up there either. You have to do this high enough that the paneling then covers tape and wind barrier.

Good luck with the project

In 25 years at various house factories, I have not experienced placing the flashing under the wind barrier.

I am completely fascinated by the volumes people expect will literally spray against the wind barrier. I agree that in theory, there is logic in having the sheet metal inside the fabric, tape, and a number of incantations to ward off the last water molecule.

In practice, a panel is sufficiently tight, and a sheet nailed at the same level as the battens works well enough, and then the air gap takes care of the rest. It rains sideways for a few days, and even then, water doesn't pour from the overhangs.

Sheet metal under only the ridge I've seen damage from.

Sheet metal on battens I've never seen damage from.

Sheet metal under the wind barrier is more cumbersome when you want to make adjustments, replace sheet metal, or windows.

What do you do if you have facade panels without a wind barrier?

I am completely fascinated by the volumes people expect will literally spray against the wind screen. I understand that in theory there is a logic in having the sheet metal inside fabric, tape, and a number of incantations to ward off the last water molecule.

In practice, a panel is sufficiently tight, and a sheet metal nailed at the same level as the batten is good enough, and then the air gap takes care of the rest. It rains sideways a few days per year, and even then water doesn't flow from the cover strips.

I've seen damage from sheet metal only under the cover.

I've never seen damage from sheet metal on battens.

Sheet metal under the wind screen is more complicated when you want to make adjustments, replace sheet metal, or windows.

If precipitation were the only moisture load...

Buy better quality sheet metal so you don't have to replace it. It's cheaper and less complicated than replacing moisture-damaged construction and materials.

If one deviates from the theory, one should at least perform a risk assessment (probability and consequence) and consider whether it's worth it.

What do you do if you have facade panels without a weather barrier?

Elaborate. Facade panels of? Unventilated?

 

[useless]

Develop. Facade panels of? Ventilated?

For example, panels like these: https://www.isover.se/produkter/isover-fasadskiva-30

My question was whether the carpenter is right about how the sheet metal should be placed 😉

 

[Evalarsson36]

It seems like you have a serious carpenter.

In a facade, it is the wind membrane or equivalent that makes the wall airtight. The facade itself is just an outer protection against sun, rain, and wind that takes most of the rain, but it is the wind membrane that should be 100% tight, and some moisture and water can run on it.

I therefore always install ÖB inside the wind membrane so that water can flow correctly. Yes, it requires some skill and precision. My way is then to tape the wind membrane to the sheet so that water cannot blow up there either. This must be done high enough so that the panel then covers the tape and wind membrane.

Good luck with the project

Thanks for a good answer. What is ÖB?

Sorry that I forgot. It could also be the case that one is working

 

[martinradbo]

Thank you for a good answer. What is öb?

öb = överbleck

For example, these kinds of boards: [link]

The product should have an underlying wind-tight construction according to their description (wind board, for example). If the insulation board is wind-tight and part of the wind-tight construction, drip edges are placed behind the wind-tight construction.
