Frilly..another opinion.
This is our last house ( that is the plan anyway ) and we built it to age in place. We chose fiber cement way before it became commonplace because of its properties. Therewas no waste. Waste is brought on by the installer's plan or skills (or lack of) your long house lends itself to long runs so less cutting. You can get the long laps in different heights ( exposures ) We had no problem with splitting..it cannot be hammered ..it is drilled... A sharp bit and a drill is what is needed. Our house is 16 years new and even on sun exposed sides..the paint is like new - no kidding. Goiod paint on fiber cement LASTS..plus its insulating qualities wjill add to your needs. I see no reason why it cannot be drilled into your present siding BUT that needs to be certified by a contractor. I spoke tomthe James Hardie folks in austrailia trying to learn...I wanted a fiber cement " tile" roof...they will not do it in areas beyond a certain geography ( at least then ) because of failure..not sure if heat or cold.. Or what the issue was. Those tiles weigh also but we live in a SIP house and the walls support the roof in such a way that was no issue. I looked for easy care..log lasting...insulating ( our walls are solid core foam as ismthe ceiling anyway ) little need for painting ( technically the cement boards do not need to be painted ) No rot. At the time no trim was available so we used cedar and painted it. No termites. I am not sure what its burn factor is.. So I guess you see I am a fan of Hardiplank. No experience with other like brands. It pressure washes beautifully!
Don't squat with yer spurs on!
People try to turn back their "odometers." Not me. I want people to know 'why' I look this way. I've traveled a long way and some of the roads weren't paved
