Johns Manville R24 Fibreglass Batt Insulation

R-24 JM insulation is a fiberglass batt insulation manufactured by Johns Manville designed to provide high thermal resistance for wall systems, particularly in 2×6 wall framing. It helps reduce heat transfer, improve indoor comfort, and increase energy efficiency in residential and commercial buildings.

What R-24 Means

The R-value measures how effectively insulation resists heat flow.

• R-24 provides strong thermal protection for exterior walls.

• Higher R-values mean better insulation performance.

• Helps keep buildings warm in winter and cool in summer, lowering energy consumption.

Material and Construction

R-24 JM insulation is made from bonded fiberglass fibers that trap air pockets, slowing heat transfer and improving thermal efficiency. The batts are pre-cut to fit standard stud spacing, making installation quick and convenient.

Key characteristics include:

• Formaldehyde-free fiberglass

• Fire-resistant and non-combustible

• Moisture and mildew resistant

• Sound absorption for quieter interiors

• Durable and will not rot or deteriorate
