Honest question: modern builds seem to have a lot of plastic, rubber and foam materials used for insulation, ventilation, etc. Won’t all of that deteriorate much quicker than 50 years? Things like spray foam and polystyrene seem to be in areas pretty hard to replace (or even notice they are degrading).
- eternityforest 3y agoA lot of things like that don't degrade for hundreds of years except maybe by shedding some microplastic when you wash your plastic clothes. Does spray foam have a failure mode just sitting in a wall? If it does, I wonder if they'll have some special robot to replace it one day.
- JamisonM 3y agoWell.. I don't really know. I know that the copper drain plumbing in my house was failing and needed replacing and it was a lot younger than many abs installations in the world that are just fine? It certainly could be the case that something like spray foam degrades over very long periods of time.. but you'd have to figure the savings from the enhanced insulation value over that period would more that pay for its replacement.
