TechVENT® Pro

A highly efficient non-structural composite, vented nailbase external insulation panel from the originators of the nailbase roof and wall insulation industry.

TechVENT® Pro is our flagship product, providing roof insulation under shingles or other roofing and a standard 1” airspace made with wood spacers that ventilates in all directions to cool roof in summer, retards ice dams in winter. TechVENT® Pro is made with polyiso foam (XPS optional), solid wood spacers and APA/TECO rated OSB or Plywood. Fully machined panel features tongue and groove foam edges for minimal heat loss. 

TechVENT®Pro is made to order for specific architectural/commercial applications with Polyiso foam (thickness to 8”/R-values to 39) with minimum 7/16” OSB and optional OSB and Plywood single/double layer sheathings. TechVENT®PRO is a non-structural insulation panel that attaches to your structural roof deck—metal, wood or concrete. 1.0” airspace standard, 1.5” and 2” optional.

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
  • Largest vent space available— 10 sq. in/ft at 1.0” intake
  • Most net free area in the panel—greater than 92% 
  • Solid wood spacer blocks— 27 per panel
  • Spacer blocks no more than 12” apart in any direction
  • Rabbetted wood edges create expansion gap perfectly
  • No need for h-clips or spacers to give proper sheathing spacing for expansion
  • Air flows in all directions over 86% upslope and over 50% cross ventilation

*Approx. overall panel thickness based foam thickness, single layer 7/16" (11.1 mm) OSB, and standard 1" (25.4 mm) spacer height. **Product LTTR R-value consists of polyiso insulation portion only for single layer vented systems. 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.
