Fanfold Insulation FAQs: Your Savings Questions Answered
Hopefully, this guide has helped you understand the benefits of fanfold insulation. Here are some frequently asked questions to further clarify its advantages and application.
What exactly is fanfold insulation?
Fanfold insulation is a type of rigid foam board insulation that is pre-folded into a compact, shingle-like package. It’s designed to be installed under siding or other exterior finishes. Think of it as an extra layer of protection against heat loss and drafts.
What are the primary benefits of using fanfold insulation?
The main benefits include improved energy efficiency, reduced heating and cooling costs, added impact resistance for your siding, and a moisture barrier. By minimizing air leakage, fanfold insulation contributes to a more comfortable and consistent indoor temperature.
Is fanfold insulation difficult to install?
Generally, fanfold insulation is considered relatively easy to install, especially for DIY enthusiasts. It’s lightweight and the fanfolded design allows for quicker coverage of large areas. Always follow the manufacturer’s instructions for best results.
How does fanfold insulation compare to other types of insulation?
Fanfold insulation primarily adds an extra layer of exterior insulation, whereas fiberglass or cellulose insulation typically fills wall cavities. Fanfold provides a continuous thermal barrier, reducing thermal bridging more effectively than cavity insulation alone. Fanfold insulation is also more moisture resistant than some other insulation types.
Hopefully, you now have a solid understanding of fanfold insulation and how it can help you save money. Time to get insulating!
