The difference between vinyl siding and Hardie board starts with material: vinyl is made from PVC, while Hardie board is fiber cement, two very different materials. With 7,000+ installations completed since 2011, Coastal Windows & Exteriors is a woman-owned exterior remodeling company serving 730+ towns across Massachusetts, New Hampshire and Maine. We install both vinyl siding and Hardie board, so our recommendations come from hands-on experience with each material rather than a single product line.
Fiber cement offers a premium look with higher upfront cost than vinyl. Vinyl delivers strong value and low maintenance for budget-minded homeowners. Knowing the difference helps you choose the right siding for your goals.
What Homeowners Need to Know
- Material Composition: Vinyl siding is manufactured from PVC plastic while Hardie board combines cement, sand, and cellulose fibers. This fundamental difference explains why the two products perform differently across weather conditions.
- Fire Resistance: Hardie board fire rating reflects fiber cement’s natural resistance to ignition and flame spread. Fewer than 2% of all home fires originate from exterior wall surfaces, making fiber cement’s added protection meaningful.
- ROI Comparison: Fiber cement siding delivers an estimated 121% return on investment nationally versus 118% for vinyl siding. Both are strong performers, but Hardie board edges ahead for homeowners maximizing resale value.
- Maintenance Difference: Vinyl siding requires virtually no maintenance beyond occasional cleaning throughout its lifespan. Hardie board needs a paint refresh every 10 to 15 years but delivers superior durability and fire resistance in return.
- Energy Performance: Installing insulated vinyl siding improves a home’s air tightness by an average of 11%. Hardie board paired with HardieWrap weather barrier cuts natural gas or heating oil consumption by 15%.
- Cost Comparison: Vinyl siding averages $18,000 nationally while fiber cement averages $21,500 for a full home project. Homeowners should weigh upfront cost against long-term performance when choosing between composite siding vs vinyl.
