The term "maintenance free" is always a guaranteed generator of sales. Vinyl siding, in the context of the lifespan of building products, lives up to this claim. Architects and historic commissions, as a rule, hate it with a fiery passion. Arguments that wood siding can be maintained indefinitely are made people with the money and motivation to do so.
What is curious about vinyl, however, is that is used exclusively as a visual substitute for wood products. It has never been marketed for its unique aesthetic character. Ah, plastics.
