My neighbour has installed hardi-Plank of the type most similar to conventional wooden clapboard, on the two ends of an A-frame summer home; in recommended manner and it is painted.
He has noticed some 'crumbling' of the leading edges of some of these clap-'boards'.
So now we are wondering; did the product got wet while in storage before sale; and frost has now (a couple of winters later) caused the edges to erode. Or was it a 'bad batch'?
Perhaps there are are/is basic problems with the product? It is advertised as 'resisting', cold, fire, damp, insects etc. That seems fair enough; cos nothing, except perhaps seam welded stainless steel, would be 'impervious'?
Hardi-Plank and/or similar products would, on the face of it, seem to be ideal. making house somewhat fireproof, as quiet as wood clapboard compared to vinyl siding in our, at times, high winds and can be installed in/with pretty conventional manner/tools?
Any comments advice or opinion about this type of product would be appreciated; for example had been thinking of using it as replacement for 10 inch (8 inch reveal) clap-board on our 60' by 36' single storey bungalow. But if edges 'crumble' not so sure.
