Hi,
I recently bought a brand new townhouse and I don't believe the roof insulation is correct to the building code so the insulation contractor is coming out to look at it and explain but before they come I want to clarify one thing.
When for example the building code says the roof insulation should be greater than 4, does putting R4 batts down between the timber beams count as getting an overall R value of 4?
I would have thought that the wooden beams will have an R value less than 4 so really they need to be covered by insulation as well. Is my thinking correct?
To meet the code should there be insulation over the wooden beams? Has anyone else argued this with a contractor before?
Thanks
