Question:

which is better, fiber cement or vinyl siding, cement obviously lasts longer but what about energy efficiency?

I'm looking to install siding on my home and just looking for answers to the obvious concerns....... maintenance, longevity, and energy efficiency>

Answer:

From an evergy efficency standpoint, neither has enough R value to even enter into the decision. With vinyl siding, you can add a rigid foam insulation behind the siding prior to installation that will increase the R value and some high end vinly comes with a foam insulation already laminated to the back. Hardi Board makes a pre-painted siding that has a 15 year warranty on the paint job. It doesn't ding, crack, or blow off in a strong wind. Plus, it looks like authentic wood siding (but much less expensive) However, you will pay substantially more than vinyl siding. For most people it comes down to price. When given all the facts, fiber cement is by far the superior product but if its not in your budget then vinyl siding is a respectable alternative.
