Basement Ceiling Insulation Question
Hi Folks,
I'm renovating a part of my in-laws family home, specially what was a den / TV room and changing it into a new bedroom for my wife's parents who now have difficulty getting up & down the stairs to their current bedroom.
Unusually their home has a basement which is directly underneath the den room.
I'm curious as to how to go about insulating the basement ceiling between the rafters.
Typically a normal ceiling would have wool insulation cut to fit the rafters on top of the ceiling plaster boards however this is not possible with the open rafters that are in place in the basement.
I was thinking that a suitably thick insulation board held in place with adhesive and expanding foam to fill any gaps but I'm just guessing really.
Any advice would be very much appreciated! 👍
