Thermapan Structural Insulated Panels

Nailbase Panels

Overview

Nailbase SIPs are suitable for applications involving insulation improvements, or when a structural wall or roof panel is not required.

Product Facts & Details

  • Exterior Walls: Nailbase panels are suitable for adding insulation to an exterior wall, by removing its existing siding and installing the panel directly to the structure. New siding is then affixed to the nailbase.
  • Added Roof Insulation: For those flat or vaulted roofs requiring extra insulation. Simply remove the roof shingles or other, install the nailbase panel to the structure. New shingles are then affixed to the nailbase OSB.
  • Flat Ceilings: Can be installed on the underside of a roof truss to make an insulated ceiling.
  • Vaulted Ceilings: Timberframe and log homes typically have structural ceilings with maximum 4’ o/c purlins and 1.5” (minimum) pine or cedar finish.
