Why homeowners choose this
What actually decides the job
Contoured foam backing fills the void behind the panel, which is what stops the wavy look on an uneven older wall.
The added R-value is real but modest, and it is continuous — it interrupts thermal bridging through the studs, which cavity insulation cannot do.
Foam thickness changes every trim detail. Window returns, corner posts and door casings all need to account for the added depth.
What drives the price
Where the number comes from
Roughly a 30–50% material premium over standard vinyl, offset against the fact that the wall is already open.
What we find
Most common failures on London walls
Treating it as a substitute for attic and air-sealing work, which return far more per dollar in this climate.

Is insulated vinyl siding worth it in Southwestern Ontario?
It makes most sense when the wall is being re-clad anyway, when the existing wall is uneven, or when the house has an uninsulated cavity that cannot easily be filled from inside.
