Asked Questions

Does the hole size matter when installing blown insulation?

At CosyWall, we often get questions about the size of the hole we blow through. We’ve been blowing insulation into New Zealand homes for more than 18 years, and over this time we’ve tried different hole sizes from large to very small to test the difference in installation quality and performance.

What we’ve found is that there is an optimum whole size that enables us to do the job properly, and we choose that hole size based on your specific house. If you’d like to know more, please contact the team at CosyWall and we’d be happy to chat!
