Insulating exterior basement wall above ground

[sparky67]

Maybe this isn't directly garage related but Ive got my workshop in the basement currently. The exterior walls are insulated with 2" rigid insulation board up to grade level. I'd like to finish this off up to the sill plate with more 2" rigid insulation. The problem is how to cover it? If I look at the instructions for something like a stone veneer system they say not to use it on rigid insulation over 0.5". The concern is the weight of everything would bend the fasteners because they are not supported in the foam. Honestly cant see this being a problem for such a short height but I also dont want to fill the board up with lots of fasteners since that kind of defeats the purpose. Has anyone tried this?

Whatever I do here I will probably do on my garage stem walls as well just to complete the look.

Great question. The new building codes in NY require that exposed wall to be insulated. I'm curious how that's supposed to be done without it looking like ****.

On my garage, the outside of the block stem walls are insulated on the outside, from the footing to sill, with 2" Blueboard. Those portions exposed above grade are covered with aluminum trim to protect it from abrasion and photo-degradation. The trim coils are purchased in 2'x50' rolls and can be had in several colors. I had access to a break, which was used to first create a 'Z' strip at the top with one edge up behind the siding and the other over the top of the foam a couple inches. Then the trim was cut into lengths to go from the 'Z' strip to at least 6" below grade and the edges were bent into an inter-locking joint. The top edges were fastened to the 'Z' strip with self-drilling screws. It has been about 8 years now with no problems.

You could also consider styrofoam panels covered with pea stone.

Here's an example from a google search- http://www.skirtingdirect.com/Merch...uct_Code=Insulated502&Category_Code=insulated

I've seen similar product sold at Menards.

I did a trowled on thin set grout. Don't have a pic right now but it's lasted 15 years.

Often I insulate from the inside.

Often I insulate from the inside.

I think this is a better idea. Insulation on the outside of a foundation makes a wonderful housing complex for termites and carpenter ants.

Here's a picture of what I have. I don't remember the exact product, but it's essentially a mortar mix that you can trowel on to the blue board.

im sure using a parge coat works but i would hate for a lawn mower to kick a rock or something bounce off the parge and shatter a lot of the coating. Luckily there isnt any codes to ridged insulation on the exterior of homes. It seems like a pain to make aesthetically pleasing. Not sure if this is a part of the national standard but seems that everyone is on there way to making a universal code.
