Why is there such a big difference at the same lumberyard?

[kurlakarl]

Picked lumber myself. Same batch and sold as the same quality. Why is it so different?

Cut from different trees? What quality have you paid for?

I'm wondering why you choose timber with heartwood and cracks when you pick it yourself at the lumber yard?

Byggmax? 😉

They are probably the same, right?
Meaning they're both crap. There's probably no good timber to buy at the lumberyard since the singers want to get the widest planks possible from small-diameter wood.

Here where I live, you can buy southern Swedish wood, with slightly wider growth rings.
Or choose Norrland's wood, with slightly tighter growth rings, but also a more expensive price per meter.
But you have to be careful sometimes, when the Norrland lot is gone, they fill it with southern Swedish wood.
Until they get the Norrland lot again.
And then you might have to pay the high price for the lousy wood 😡💸💸

I'm wondering why you choose wood with pith and cracks when you pick it yourself at the lumberyard?

Because I have an academically high-paying job with specialist knowledge in a completely different field, and I do some woodworking as a hobby for fun and don't know anything professional about woodworking and don't work with forestry or whatever other background one might have if they know terms like "pith" when talking about boards.

 

[kurlakarl]

In what way do the properties of my wooden facade change depending on whether it consists of one type of board or another?

 

[Timmermannen77]

You should choose the densely grown ones, the facade will last much longer.

You should choose the dense-grown ones, the facade will last much longer

Some parts need to be replaced on the house due to rot, unpainted end grain. Would this not have happened with dense-grown wood?

All wood decays sooner or later. On a facade that is correctly constructed and regularly maintained, the quality of the lumber has relatively little impact (as long as one stays within reasonable limits, of course).

Not nearly as quickly. Treatment of the wood reduces the difference, but not completely.

unpainted end grain

The end grain should ALWAYS be painted when repainting the facade. Even many new houses with vertical facade panels lack treatment of the end grain, it should be fixed ASAP if you want to avoid future problems. To be really meticulous, vertical facade panels should additionally be beveled at the end ("drip nose") to prevent water from settling at the bottom edge of the panel.

To be really meticulous, vertical facade panels should also be cut at an angle at the end ("drip edge") to prevent water from settling at the bottom of the panel.

I know! Addressed some of it on the house already. Very annoying as the facade and paint are otherwise great, but the end grain is completely rotten on several walls..

The end grain should ALWAYS be painted during the repainting of the facade. Even many new houses with vertical facade paneling lack treatment of the end grain, which should be fixed ASAP if you want to avoid future problems.
To be really meticulous, the vertical facade paneling should also be beveled at the end ("droppnäsa") to avoid water settling at the bottom of the panel.

Droppnäsa is a myth, it works just as well without.
