I have a 1100sqft ranch, vinyl sided w/ wrap in northern Michigan; 165 ft vented crawl perimeter, 4 block high w/ one block exposed to exterior. COLD FLOORS. Hot water baseboard heat with pipes in crawl along with water/sewage. Poly on ground , up wall attached to sill plate. Perimeter dry but damp in center of crawl in spring. Fiberglass betw joist at sill plate. Will insulating perimeter give warm floors? If so, what type insulation? Rigid? Fiberglass? Fire rated? How to install? Am I correct in not insulating hot water heat supply pipes? Thanks.
