Air gap baseboard

[Gieron]

Many install the baseboard directly against the existing foundation with insulation in between. According to the manufacturer, there should be an air gap between the board and the insulation. I am thinking of digging the board a bit into the ground, and then there will be no ventilation in between. The easiest way would be to drill plugs and screw the boards directly to the wall. I currently have cork as insulation. Is there a risk of moisture damage to the foundation if I were to mount the board directly against the cork or alternatively cell plastic?

Hello and welcome to Byggahus!

Even if you bury the board a few decimeters into the ground, the foundation above ground can still be ventilated if you follow the manufacturer's installation instructions.

Even if you dig the board a few decimeters into the ground, the foundation above ground will be able to ventilate if you follow the manufacturer's installation instructions.

Steni specifies a gap at the top and bottom of 8-10mm if you are to follow their instructions. That makes it more difficult, but maybe a gap at the top with rubber spacers as recommended would be enough.

I have Steni on my foundation and it is above ground, but no insulation behind. I framed with 22X75 pressure-treated wood and attached the panels to them. At the top, it's open just below the panel; at the bottom, I drilled 2 holes of 50mm about 10 cm from the ground symmetrically on all boards, before installation I glued insect mesh in copper over the holes on the backside. It ventilates quite well behind the panels.
