What’s the Difference Between Insulation Boards and Batts?




Looking for a durable, versatile way to save on energy bills by increasing your home’s energy efficiency? Rockwool insulation is made from premium stone wool and can boost indoor comfort by improving a building’s thermal and acoustic performance, retaining heat, and absorbing sound. With an R-value of 4, Rockwool insulation is hydrophobic, so it won’t absorb moisture or water, and once dried, it maintains its original R-value.

Compared to fibreglass insulation, Rockwool insulation creates less risk to health and safety during installation. It exceeds fibreglass insulation performance for sound and fire, has less harmful environmental impacts, and can be cleaner to install. Termite problems? While these pests love foam insulation, the fibres in stone wool cut them, so they tend to leave it alone.

When selecting insulation for your home, you might be wondering what the differences are between Rockwool insulation batts and boards.

With ROCKWOOL ComfortBatt, bring the cost-savings and comfort indoors.
