Low Thermal Conductivity Phenolic Foam Insulation Board 30 mm Closed Cell

Low Thermal Conductivity Phenolic Foam Insulation Board 30 mm Closed Cell

Low thermal conductivity is the reason phenolic foam holds a place in tight construction. At a mean temperature of ten degrees the foam measures 0.032 W/(m.K), which lets a 30 mm board do the work of roughly 45 mm of EPS. For a duct lining or a wall where depth is fixed, that difference decides whether the design fits.

The low thermal conductivity comes from a fine, uniform cell structure rather than from heavy density. The board stays light at forty to fifty five kilograms per cubic metre, so installers can carry a full sheet up a ladder, and the closed cells keep moisture out of the foam in humid service.

Boards are laminated on a continuous line with embossed aluminium foil on both faces, and the non woven interlayer gives a reliable bond between foil and foam. The result is a low thermal conductivity phenolic foam insulation board that holds its declared value after handling, cutting and fixing on site.

Key Advantages

• Conductivity of 0.032 W/(m.K) at 10 C mean temperature
• Fine closed cell structure keeps the value stable in humid service
• Light board weight at 40 to 55 kg/m3 for easy handling
• Foil facing on both sides adds a reflective surface
• Dimensional change within 2.0% after 7 days at 130 C
• Cuts cleanly with a fine tooth saw and leaves a square edge
