Johns Manville DuraCore® fiber glass insulation is a lightweight, highly resilient, blanket-type insulation manufactured using borosilicate glass fibers bonded with a thermosetting resin. DuraCore is manufactured  to produce a more durable insulation with enhanced core strength that makes it more rigid and less susceptible to delamination. State-of-the-art fiber glass technology produces a lower thermal conductivity (“k”) value to meet all your thermal performance requirements, in an easier-handling blanket.
