How does Hardie Plank compare to other materials? My wife and I are building a new home and like Hardie Plank, but can't get the nagging feeling that it won't last as long as the dealers tell us. It is a painted surface and I'm concerned it will require too much maintenance over the course of 20-30 years. Also, I am concerned the insulating properties aren't very good. Any advice or information?

Insulating properties are nil. Insulation should not be a factor. Take care of the insulation inside the wall or under the siding and use a good house wrap.

Maintenance is the same as any exterior painted surface and will need to be repainted periodically. How often it needs painted will depend on the grade of paint used and the number and thickness of the coats.

Hardiplank siding is far superior to the Masonite or hardboard siding it was meant to replace.

Hardie-plank is a good, durable siding material with a long life span. It holds paint better than wood and is less susceptible to water damage. Hardie-plank is more difficult to install correctly than wood.

Don't look for meaningful insulation gains in any type of siding. If you need insulation, install it in the wall cavity between the studs (such as R-13 fiberglass batts) or skin over the outside of the wall with 1" styrofoam or urethane board (R-7) before applying new siding.

Anything that is painted will eventually need to be re-painted. Under like conditions, Hardie-plank will hold paint as much as twice as long as wood. If you want no maintenance for 30 years, install masonry and don't paint it.

Hardie-plank is a good durable siding material and holds paint well compared to wood.

Don't look for meaningful insulation values in any type of siding. If you need insulation, add it to the cavity between the wall studs (with products such as fiberglass batts or blown-in insulations with a R value of 13 or more) or "skin" over the outside of the walls with 1" insulation panels (such as urethane or styrofoam with a R value of 7 or more). A lot of contorted hype accompanies products and their R values. Be careful!

In my experiences, paint holds at least twice as long on hardie-plank as it does on wood. If you want NO maintenance for 30 years, install masonry and don't paint it.
