Air tight recessed lights on first floor
Hi all, been looking for an answer to this but can't seem to find. I remodeled my 1st floor and put some recessed can lights in. The contractor put in IC, non-air tight cans. Should I put in airtight trims? I know it isn't as big a deal as drafty cans that are under an attic, but I have to wonder am I just wasting energy by essentially turning the formerly unconditioned interstitial space between 1st and 2nd floor into a conditioned space. Any thoughts or links appreciated. I ask because the air tight trims in the style I want are twice the cost of the already spendy non-airtight trims. It adds up quick.
