How To Choose The Thickness of Glasswool Insulation for Internal Wall

To choose the appropriate thickness of glasswool insulation for an internal wall, you need to consider the R-value required for your specific climate zone. The R-value is a measure of the insulation’s ability to resist heat flow, and the higher the R-value, the better the insulation performance.

You can consult with a local insulation contractor or refer to the building codes in your area to determine the recommended R-value for internal walls. 

Once you have the recommended R-value, you can use a insulation thickness calculator to determine the appropriate thickness of glasswool insulation needed to achieve that R-value.

It’s important to note that the thickness of insulation alone may not be enough to achieve the desired R-value. Proper installation and air sealing are also critical factors in ensuring optimal insulation performance.
