Insulating Pier And Beam Floor

Sharing my technique how i insulate my cabin floors and keep them rodent free.

Insulating pier and beam floor.

There s also an extra bit of insulation from the air under the home saving you on energy costs. It will provide additional insulating value for not too much more than what would be invested in the r30 insulation. Adding insulation mitigates the problem but there are some considerations to keep in mind. If you want to insulate a floor assembly by leaving the joist bays empty and installing rigid foam on the underside of the joists here are a few things to keep in mind.

Alternatively you could fill the cavity completely using r 38 faced batt insulation. An uninsulated floor allows heat to escape making the house less energy efficient. Pier and beam foundation homes in wetter climates may opt for this choice because foam insulation is typically resistant to mold. According to the 2012 irc the minimum r value for floor assemblies is r 13 in zones 1 and 2 r 19 in zones 3 and 4 r 30 in zones 5 and 6 and r 38 in zones 7 and 9.

Some homeowners prefer the feel of the wood platform over a concrete floor. Lots of people asking if they could use this in the walls and ceiling. If you would prefer to install the insulation without the help of a professional one option would be to use foam boards. The air space above the 9 1 2 inch insulation in the 12 inch joist cavity will help provide a warm floor inside the cabin.

These stiff boards are placed close together on top of the floor joists.
