Wikipedia says "a type of gypsum wall board with holes spaced regularly across it, usually in sheets sized 2 feet (24 in) by 4 feet (48 in).The holes serve the same purpose as the spaces between the wood lath strips, allowing plaster to ooze through the board when the plaster is applied, making the keys to hold the plaster to the wall board." There is a pic in this thread (right hand walls): closed cell foam insulation? I know buttonbard is not common in some areas.

I know a main advantage of method #1 is that if we want to do all new electric and insulate the walls, it would be a lot easier with the studs open and give us more insulation options beyond blow-in. I THINK my main alternatives are:ġ) tear off all the buttonboard and replace with new drywall Ģ) leave buttonboard in place and skim coat all the interior surfaces ģ) leave buttonboard in place and put a new layer of 1/4" drywall over it (I don't care about losing 1/2" of interior space per side).Īll things being equal (which I know they never are),ġ) What would be the main advantages and disadvantages of these 3 alternatives?Ģ) what would be the probable difference in cost of the three methods? enough that I would like the walls to look new when we are done. We have buttonboard interior walls and stucco exterior. Way past a weekend DIY project we will have to have most of the work done professionally. Looking at a major/total remodel of our 1200-SF mid-50s L.A.
