TechBASE® Pro

A highly efficient external roof insulation panel from the originators of the nailbase roof and wall insulation industry.

TechBASE® Pro provides roof insulation where ventilation is not required, often under metal roofing. Fully machined panel features tongue and groove foam edges for minimal heat loss. TechBASE® PRO is made to order for specific architectural/ commercial applications with Polyiso foam (thickness to 8"/R-values to 45) with minimum 7/16" OSB and optional OSB and Plywood sheathings.

Key Features

  • Fully machined panel guarantees squareness
  • Saves time on the jobsite with easy fit panels
  • High R-values in a single layer—less labor than two layer systems
  • Rabbetted wood edges create expansion gap perfectly
  • No need for h-clips or spacers to give proper sheathing spacing for expansion

*LTTR R-value calculations are based on ASTM C1289-11A, effective January 1, 2014.

NOTE: Always refer to local building codes. Use of synthetic underlayments is strongly suggested for superior water resistance. Use of a vapor retarder is highly recommended in moisture prone applications. It is always recommended to have the roof assembly dew point calculated by a qualified architect or engineer to ensure proper usage in the chosen environment.
