Many people automatically associate pink fluffy rolls with insulation. This fiberglass material is the most commonly used type of insulation throughout homes, but it does not belong everywhere, namely in the crawl space.
Crawl spaces are typically damp, and water can easily infiltrate fiberglass, lead to mold growth, harbor pests, and render the insulation ineffective.
To stand up to crawl space challenges, the best choice is thermal insulation boards made of expanded polystyrene. Our ExTremeBloc crawl space insulation does just that. It’s also waterproof and pest-resistant.
