The last thermal bridge
After we have broken every thermal bridge in our latest project house with double studs or continuous exsulation and our slab is a barge on a sea of rigid foam, the only thermal bridge that remains is a piece of metal with a large surface on the inside to conduct our heat to an equally large radiator on the outside. We put one (or two) on every exterior door.
What to do about the doorknob?
Is there such a thing as a thermally broken doorknob (that still looks respectable) for a front door?
