Johns Manville High Density Batts

 

Johns Manville has developed a line of high density batts for 2 x 4, 2 x 6, or cathedral ceiling applications. This enables the builder the option of increasing the R-factor of the job or substituting lighter framing members to save cost without sacrificing the overall thermal efficiency. When used in a cathedral ceiling application a ventilated roof can be obtained while still using standard 2 x 10 or 2 x 12 framing.
