Q-Rite and Hitz Halter are both high quality, foam insulations that are designed to be used for Radiant Floor heat and other below-grade applications. The foam is covered with a clear or reflective film of your choice (selective thicknesses in stock) which serves as a vapor barrier, so there is no need to install an additional vapor barrier. Are you wondering what your best option is for below grade insulation? You have found the right place! Q-Rite and Hitz Halter are both popular choices, below we will run through the features and benefits of each one to help you make the choice that is right for you!

As you can see above, both Q-Rite and Hitz Halter are treated to be termite resistant. Q-Rite has more easy to install features. Both have multiple thickness options available. Both have the same EPS foam insulation, however, the film is a bit thicker on the Hitz Halter making it the premium below grade choice, but not without a price increase.

Conclusion: Both are great options, but when it comes down to it, the question is, do you find it worth the price increase of the Hitz Halter in order to gain 1.5 mil in film thickness increase? Can you save enough labor by going with larger pieces? This is something that only you can decide.
