Batts v. Blown-in Round 2: Where to use Havelock Wool products?

November 23, 2021 by Andrew Legge 6 Comments

Blown-In and Batt Insulation

We wrote a piece back in the middle of the summer outlining the difference between blown-in and batt insulation.  A copy can be found here.  As ever we try to take and share a view that is devoid of bias; our goal is to help you make informed decisions.  The piece was well received and we enjoyed quite a bit of conversation on the back of the publication.  

What we did not speak to (intentionally) was the application differences between Havelock Wool batts and blown-in insulation.  To be fair we offer both products so as to ensure there is optionality for the end-user.  In other words, we are not here to convince you one is better than the other.  That said, we are frequently asked what makes the most sense for a given project.  We do indeed have an opinion and see nothing wrong with sharing it. 

So, here is our response to an increasingly frequent question:  If I am building or renovating a house, where should I consider Havelock Wool’s products?  

Location

Interior Walls

Between Floors

Ideally, this is a quick yet useful follow-up for the best application of Havelock Wool products.  Any / all follow-up questions or comments are well received.

    Is your blown in product accepted in California?

    in crawl spaces, below a old floor and subfloor, what do you reocmmend to install between floor joists? Same as between walls. We are here in Central Oregon where crawl spaces with exposed dirt/earth is very cold and drafty
