I am finishing my above ground basement. Should I insulate the ceiling joists before I sheetrock them?

 

[rspainhower]

anybody?

I would say no unless you were looking to absorb some sound or were trying to isolate heating zones. RT

 

[rspainhower]

My main concern is sound. What is the best inexpensive way to keep sound down?

 

[K2]

Be very quiet. :cheesygri There is a thread around here on sound proofing. I know from having rentals for 20 years that sound between floors is a tough one unless you can put gypcrete or light weight concrete on the upper floor.

A drop ceiling will absorb sound a lot better than sheetrock, fyi.

 

[rspainhower]

Drop ceiling is out of the question for code height and asthetic reasons. What are my options with rock ceiling?

5/8 rock and R-15

 

[rspainhower]

what about resiliant channels? I have been doing some research, do they help sound more than insulation?

 

[nywoodwizard]

who's going to live upstairs metalica?

 

[rspainhower]

But if I did resiliant channels instead of insulation would it be more sound resistant?

 

[reveivl]

yes

 

[slickshift]

Homesote, then sheetrock
With a space in between if you have enough room, even for just firring strips

An ultra dense vinyl sheet (soundproof) then sheetrock will work much better, but it would be more expensive (though less labor)

ok, I decided to bag the rc channels. I bought some r-13 insulation, should the paper face the upstairs floor or the basement ceiling?

 

[Mike Finley]

[rspainhower]

R-13 that won't help you we used it for years it's no bueno for insulation or sound proofing. (Unless you live in a hot spot.)


Go with a R-20 something and 5/8's rock.
