R50x24''

R‑50 insulation from Johns Manville is a high R-value insulation designed primarily for attics, ceilings, and large roof assemblies where maximum thermal resistance is required. It helps maintain energy efficiency by minimizing heat loss in winter and heat gain in summer.

Key Features

• High Thermal Resistance: Provides R‑50, ideal for cold climates and energy-efficient buildings.

• Fire-Resistant Options: Depending on the type (fiberglass or mineral wool), it provides excellent fire safety.

• Sound Control: Reduces noise transmission through ceilings and attics.

• Moisture Resistant: Fiberglass and mineral wool versions resist mold and do not absorb water.
