ABT CO Northern Star – Basic Insulated Siding D4

What we have is a premium thickness no frills INSULATED vinyl siding. It comes in only the most standard D4 clapboard profile and a limited color selection. The insulation part in a insulated backerboard made to fir the profile although it is a secondary product. Like most ABT CO sidings in this range there is a double thick nailing hem which adds some rigidity. We do like insulated vinyl both for durability as well as efficiency. This is kind of a starting point with only R-3 insulation you can do better but you could also do much worse.
