Composite Siding

Alside Ascend Composite Siding — 5" Plank (S5)

Brand: Alside

Ascend 5" Plank was introduced by Alside in September 2026. It uses the same composite build as the 7" plank — a rigid, glass-reinforced polymer shell over a graphite-infused foam backing — in a narrower course that recreates the tight lap spacing of older New England homes. More courses per wall means more material and labor per square, which is why the 5" plank is priced above the 7".

It comes in the Cedar Mill woodgrain texture and is offered in the same Ascend color palette. Because it is brand new, we confirm color availability with you at the consultation.

Ascend 5" Plank offers:

  • Narrow 5" exposure for a traditional clapboard look
  • Rigid composite shell with foam backing — R-2.0 insulation value
  • Class A fire rating and a higher wind-pressure rating than the 7" plank when nailed to spec
  • Through-color finish that never needs painting
  • Lifetime limited transferable warranty with 5 years of full material and labor coverage
