Now Approved for Icynene Closed Cell Foam Line


Fi-Foil’s Thermal Barrier Blanket System or TBB™ is designed for use over Icynene’s Spray Foam in commercial and residential buildings. The patented system offers an easy single-pass installation. An innovative Clip & Pin mechanically snaps on the metal purlins, bar joists or wood beams. A reflective-faced insulation attaches with a friction washer, offering an attractive aluminum finish. TBB™ is available perforated, which allows vapor transmission, and solid, which can function as a vapor retarder. TBB™ provides improved acoustic performance over thermal barrier coatings.

The Thermal Barrier Blanket – A Complete System

The Thermal Barrier Blanket system consists of TBB insulation, Clip & Pin fastening components, and tape for sealing edges and openings around obstructions. Roll widths are 66” and 76” for 5’ and 6’ on-center framing. Each roll of insulation covers 125 to 150 square feet of building area, depending on the width of the insulation selected. Five rolls, one box of Clip & Pin components and one roll of tape cover 500 to 750 square feet of building area. Smaller boxes of Clip & Pin components are available for individual rolls.

Thermal Performance in Combination with Icynene Spray Foam

Most of the thermal performance of the system is provided by the spray foam. TBB adds additional thermal resistance from the thickness of the TBB insulation and reflective air film.

Options for Your Specific TBB Application

The fastening, or Clip & Pin, components are suitable for both metal and wood framing. The Clips mechanically fasten to the framing. Pin lengths allow for spray foam to extend beyond the inside of the frame. The system comes with locking washers, and dome cap washers are also available to improve the aesthetic appearance or cover the points of the pin.

TBB Works With a Full Range of Building Types

TBB is suitable for most metal and wood-framed commercial, industrial and agricultural buildings. Facilities include warehouses, distribution centers, industrial factories and manufacturing plants, and agricultural buildings. Other buildings, including residential, may be suitable.
