I bought a rather old house which has 2 apts inside. One of the apts. has a bedroom on an upper corner which has two outside walls. The walls are insulated with seaweed. The outside is wooden shingles and the inside walls are drywall. Last week I was going to blow cellulose into the cavities for the bedroom but the seaweed was too tight inside. In addition, although the hot water baseboard heating system goes along the 2 outside walls, only 1 wall has any deflectors on it to transmit the heat. The other outside wall only has the pipe along the base of the wall. I can somehow get deflectors or something to deflect the heat from the pipe, I can double the heat generated in the room. I'm thinking also of tearing down the 2 walls and inserting pink insulation with a vapour barrier and then drywalling over it.
Answer:
You are on the right track. I don't know that the hot water pipes in themselves will ever provide sufficient heat though so you might try looking for actual radiators to replace them with once your other work is all done.
