Project On An Island – VIII – Larch

With the roof done, and while we can’t finish the gutter because the materials are still somewhere in a truck, we finish the outside of the house. The insulation was placed already last week, with a black water shield, and now we add the final layer: larch.

The larch is spaced for optimal ventilation. It doesn’t matter if wood gets wet, al long as it is ventilated and dries after the rain. So we space the larch planks with a spacer tool for nice even spacing. Also we cut the larch in a rombus profile so that water will always be guided towards the outside of the wall. Simple techniques that increase the life expectancy of the larch.

Also, with a rhombus profile, when you look into the wall horizontally, you can’t look through the gaps and you will not see the black shield at the other end of the ventilation gap behind the larch.

Initially the larch is yellowish with a slight orange tint. Without any further treatment it will turn grey in about ten years. If you want to stop the greying process you need to treat the larch with pigmented oil. It is a simple procedure, much simpler and quicker than painting, but still most clients don’t do anything to stop the greying process, they just let it follow the natural course.
