What Type Of Insulation Should I Buy

Tiny House Recap: In yesterday’s post we determined that R-value (the standard measurement for insulation) is an¬†insulating¬†material’s resistance to conductive heat flow. That said, insulation with a higher R-value will perform better than insulation with a lower R-value. So what type of insulation should you install in your tiny house?


The most common insulation materials are fiberglass, cellulose, and foam. Insulation types include loose fill, batts, rolls, foam board, spray board and vapor barriers. But what is what and why is it a better/worse choice than any other type of insulation?

Blown-in Insulation

  • Usually made of fiberglass or cellulose (recycled paper fiber)
  • Blown or sprayed into place with pneumatic (air compressor powered) equipment
  • Ideal for all the nooks and crannies of your tiny house
  • Can fill wall cavities and installed over existing insulation (if you are replacing or reinforcing your current insulation)

Fiberglass Batting (hint: it’s the pink stuff!)

  • Precut sections of fiberglass or rock wool insulation
  • Designed for easy handling and use between framing, such as studs and joists
  • Available either with or without paper facing
  • Can be used in floors, walls, ceilings, etc.

Insulation Rolls

  • Available in pre-cut widths to fit between studs and joists
  • Come in continuous lengths ranging from 20 to 40 linear feet for long runs
  • Ideal for floors and other areas where longer runs are needed

Foam Board

  • Rigid panels of insulation
  • Can be used to insulate almost any part of your home, from the roof down to the trailer
  • Made primarily of polystyrene and polyurethane

Spray Foam

  • Latex or polyurethane spray foam is sprayed into place with a spray can or specially designed equipment
  • Can be used to fill small gaps and cracks
  • Ideal for sealing around doors, windows, vents, and skylights
  • Sets quickly and can be trimmed (with a box cutter), painted, or stained
