Thickness. Hardie board siding is thicker than vinyl siding, varying between 5/16 and 1/4 – inch thick on average. On the other hand, vinyl siding is significantly thinner than hardie board.

Flammability. Hardie board is much more fire-resistant than vinyl siding. It’s considered difficult to burn because it’s made out of materials that are similar to cement. Vinyl siding is more flammable than hardie board. When vinyl siding is treated with a fire retardant, it helps slow down a fire, but it still is not as resistant as hardie board is.

Durability. Both hardie board and vinyl siding are very durable. They typically don’t attract harmful insects, If impacted, hardie board will crack. It will not warp. Vinyl siding, upon impact, will warp or crack. It’s more sensitive to warping, and can warp due to something as minor as a lawn mower impacting it. It’s less likely to crack compared to hardie board because it’s more flexible and bendable.

Pricing. Vinyl siding is normally less expensive than hardie board because the installation process for it is quicker.
