I also recommend that all tub exhaust enthusiasts Have got a timer on them so you can allow them to operate longer. This pulls more refreshing air to the home and also does a better occupation exhausting moist air.
I've tyvek and 1/two″ blue tuff foam board under my siding which all covers my sill plate /rim joists etc. I'm now in process of finishing the basement. I've sprayed already good things along the sill plate/block Basis to seal the hole and all cracks within the rim joist then put my still left over r-19 faced fiberglass in the rim joists. i approach on using the 2″ blue tuff foam board versus the block Basis within the slab towards the joists and Establish my walls before it. i get the concept of the foam board towards the block Basis even so why would the insulation be bad with the rim joists? im bewildered – the rim joists are previously mentioned grade – isnt it no various in comparison to the insulation Employed in the primary stage walls?
Thanks for your reply Todd. So have you been indicating the rigid board is tight to your outer wall sheathing? Your photograph looks like it’s flush to the inside cement wall.
Mike – Bay windows and bumpouts for fireplaces are quite challenging areas. In a great globe they might be spray foamed.
Jim – I totally understand in which you’re coming from. The rim joist area “appears” just like the partitions higher than but that’s just not the case. Largely a result of the natural environment it’s near (CONCRETE WALLS :)).
Would it not be Alright to depart The existing insulation set up, and perhaps things additional fiberglass in place?
Jeff – There are many locations exactly where caulking is really a better option for air sealing. Once we do an Energy Star house all of the plates get caulked, so among the sill plate and foundation, involving the wall plates and sub-ground, etc. I might do that before insulating the rim joist, then seal the insulation towards the sill plate as well.

Wonderful web site. I learned a whole lot. Am in the course of my task. I used to be suprised with the air motion coming in from your rim joist area and also the dampness powering the fiberglass. I'm utilizing foil confronted. I started off by removing the fiberglass and cleaning the areas. I caulked the top and base with silicone, cut the foil confronted with a circular saw and miter saw. This worked well.
Michael – No want to attract, I get the idea. I’m not sure the air space is an enormous concern being straightforward. Air is an honest insulator so if it were being mine I’d just depart it. I’m assuming you’ve sealed the sides from the foam into the rafters so no drafts will get in or air might get to those voids?
Thanks. I will be checking with building inspector. I recognize the XPS should be enclosed. But I assume you suggest to set up the 1x t&g pine ceiling boards and 1/two″ drywall on the stud partitions as regular.
Also, I have Yet another problem which i requested you about in the section on basement insulation. I asked about my Dricore technique and I'll consider your assistance and try to acquire foam board driving my walls. However, I am continue to baffled about another thing regarding the air gap between the foam board plus the insulation. I've go through most your articles or blog posts and a lot of your FAQs and I discovered what is apparently two distinct replies, they had been entirely different instances so I see why you supplied two various methods but I don’t know which a single I should adhere to.

In one situation a guy experienced an enormous air gap (a few foot I believe) so you recommended him to put in more foam board to fill the air gap but usually you say a small air gap between the foam board and insulation doesn’t make any difference. I have a drain pipe working along the ceiling so I just Develop my wall out about 5″ from the foundation, consequently, if I set in two″ foam board I will however have an air hole of about 3″ with the insulation. Is this far too much? Is there a max air hole space?
