Question

Insulating a floor in the basement of a house


My brother-in-law has a basement that is heated, but not much, and the rooms upstairs (living, kitchen, etc.) get cold. The flooring is regular wood flooring. He was told by a store (big box store) to use regular insulation between the joists that is wrapped around in plastic, but has holes all through it so it really has no "facing" on it. A friend of his said that was not right and to use faced insulation and he is not sure if he used faced insulation, how to install it. Should the facing go towards the heated part of the structure (up against the flooring upstairs) or should it get attached to the joist, facing down towards the basement with a staple gun. If he puts the facing up against the flooring, what is the best way to keep the insulation from falling down.

Thanks in advance,
Bruce

Insulation on the floor/ceiling is a waste of time and money!
The basement walls should be insulated!
I'm in the process of insulating my basement walls, right now!
I'm using a product called foundation wrap. It come in rolls that are 4 ft. wide and 50 feet long. And comes attached to a vapour barrier.
The top of this insulation is stapled to the foundation sill plate and the bottom is screwed to the concrete with Tapcon masonry screws.

Where are you located for the vapor retarder?

Be safe, Gary

If the first floor is cold, have him rigid foam board the rim joist and use the foam in a can to fill any gaps.
I see no use of floor insulation in this case.
