ᐅ LED Profile – Recessed Installation for Exterior Use

Hello,

I have a new build where the plastering will start soon. It is a solid wood construction with wood fiber boards as insulation.

Now, I would like to have a continuous LED profile plastered in around the large entrance area, which is set back about 2 meters (6.5 feet) into the house, for aesthetic reasons. The electrical wiring is already in place. There are various profiles available, but unfortunately, my electrician couldn’t help me with the choice. However, my plasterer and I ran into a problem regarding how to connect the profile to the substrate.

These profiles are usually made of aluminum. The idea is to mill a groove into the insulation to insert the profile, then cover it with mesh and plaster over it. This profile runs over 2 meters (6.5 feet) in every direction. Since aluminum expands and contracts somewhat with temperature changes, cracks are expected to form at the connection points between the profile, plaster, and insulation. Although this area is protected from rain, I can’t imagine that it will hold up well over time against moisture, especially during heavy rain or condensation.

Neither my electrician, plasterer, nor LED profile supplier could advise me on this, so my question is how this is typically handled in practice. I am certainly not the first person to want to implement something like this. Are there special systems designed for this? Do other homeowners simply accept the moisture risk?

Thanks and regards

It already looks bad on the facade. In raking light, you can see every unevenness.
Use lighting only when necessary, but not as an aesthetic feature—unless you have a castle...
Just install a lamp. Cheaper, more practical, easy to maintain and replace, and also trouble-free.

I installed these profiles in my garage lintel; they were properly covered with plaster.

I’m not entirely sure what you are planning: Do you want to have them on the walls or just on the ceiling?

I want to have them on both the walls and the ceiling. So basically all around the entrance area. Since it’s a timber frame construction with wood fiber boards as insulation, it won’t be plastered like a typical masonry garage but rather filled with a thin topcoat layer. This means the profile is anchored in the insulation, which I see as a potential weak point for allowing moisture to enter the insulation.
