I have better question: why New England is building out of plywood? Why not brick&mortar or at least AAC? I know - it's freedom, so if the LAW is not prohibiting buildings made out of cardbord, everyone will be offered, like it or not, cardbord houses or condos. There will be even more plywood sold for repairs every other year, plywood with time (specially on roofs) looks like wet toilet paper. What about all that ASBESTOS you offer around heating pipes? That is so precious, so we have to pay in MA hundrets of thousands for the technology abandoned 60+ years ago in country side in the 'rest of the world'. Not to mention that cities became all-brick around 17 century. Well that's way we have so many fire departments (more work places!) and pharma-comapnies with allergy medicines (hollow walls filled with dust producing fiber-insulation). It is just great. My advice: tear down your nail-glue-and-plywood building and build something more sustainable to make it more 'sale-able'. I would call it (using a 'high-tech' vocabulary) 'Intelligent Building' -> long lasting, energy saving. Of course it has to be called 'french' (have no idea why). I would call it STOP-the-DEFORESTATION in South America and in Canada too. This will of course limit the number of rodents, termites and squirells other species living in your house, but do not worry - they will not extinct, not yet.
