Johns Manville R22 Fibreglass Batt Insulation

R-22 insulation is a high-performance fiberglass batt insulation used to improve the energy efficiency and thermal comfort of residential and commercial buildings. The R-value of 22 indicates a strong resistance to heat flow, making it suitable for areas where better insulation performance is required.

What R-22 Means

The R-value measures how well insulation resists heat transfer.

• R-22 provides higher thermal resistance than common wall insulation such as R-12 or R-14.

• It helps maintain stable indoor temperatures throughout the year.

• Proper insulation reduces energy loss, which can lower heating and cooling costs.

Material

R-22 insulation is typically made from fiberglass fibers that trap air pockets. These air pockets slow down heat movement, providing effective thermal protection while remaining lightweight and easy to install.

Fiberglass insulation is widely used because it is:

• Non-combustible

• Durable and long-lasting

• Moisture and mold resistant

• Safe and easy to handle
