The joists in between should also be insulated to provide more grip and sturdy. 

Is it worth insulating a basement ceiling?

As the heat or the weather rises as per the temperature, most of the heat gets out through the windows or loft or roof space, if the place is not properly insulated. Ceiling insulation is more worth the money and effort than insulating other places like the floor or walls.

What is the best basement insulation system?

The best materials present in the market are foam board styrofoam, spray polythene foam, insulation, fiberglass, rock wool, and cellulose. The following are the five best insulating materials and resources/ systems used: 

  • Monolithic concrete

Rigid or polyiso or extruded polystyrene (XPS) foam board can be utilized for walls for interior works and SPF should also be applied to the seals and for insulating rim joists. A less expensive option is taped foam board. 

  • Finished basement 

Before backfilling the walls, the exterior insulation should be installed. But in case features that are not temporary like patios or driveways, around the basement make the evacuating of the basement more of a costly affair, then foam board can be used for the outside wall of the foundation. 

  • Unfinished basement

A combination of spray foam and foam board is recommended, which is similar to monolithic concrete. Or in case of the non-availability of materials mentioned, you can tape foam board to air seal and heat the basement walls through insulation. 

  • Laid-up stone foundation

The approach and plan like that of the double brick, rubble-filled wall can be used for insulation. However, another expert suggests waterproofing the exterior and insulating the same with a vapor-retarding membrane.
