rigid insulation thickness for a condo/townhouse
i used 2"blue rigid insulation on the 2 exterior walls (front and rear of unit)
which gives me r10 and framed in front of that and filled with roxul safe n sound.
but for the divider walls ( we are an inside unit ) how thin (r value?) can i go...
1/2 " pink has a r3 and goes up from there
im in kitchener ontario so im trying to do it to code
any help would be great :thumbup::laughing::thumbup:
Why would you want to insulation the interior walls from the heat of the adjacent unit?
The only reason, I could think of would be to Roxul for reduced noise transmission between units.
