Comfort Board 80 vs 110 – density worth extra cost?
For our upcoming house build using 4″ of rigid mineral wool we have been quoted for both Roxul comfort board 80 and 110. Over the top of this we will install 2×4 furring and cedar siding.
The 110 has a compressive strength of 1120 PSF at 10% deflection, the 80 is only 439 PSF at 10%, using the 110 will simplify the installation of furring as it will compress less, but I don’t know that the furring installation sub would price their install any differently between the two products. (Furring install not by insulation contractor).
The cost difference is about $2,600. Is the potential for simplified furring installation worth the added cost?
p.s. GBA – The catpcha’s appear to be case sensitive, it would help if the users were made aware of this.
