Extira vs MDF

Extira is a Revolutionary Product for that Performs Better than MDF

Extira panels may look like MDF, but they don’t perform like it. Different ingredients and a patented and proprietary manufacturing process lead to a superior performance.

Performs Better Than Wood or MDF

  Extira Panels Typical MDF
  Application Exterior Interior
  Composition

Wood, phenolic resins, zinc borate, wax and other ingredients.

No added urea formaldehyde.

Wood, urea formaldehyde resin.

May emit formaldehyde.

  Manufacturing Process

Proprietary, patented steam injection technology using TEC™ manufacturing process.

Pressed between hot platens in an open press without steam injection.

  Benefits

Consistent density.

Resists moisture, rot and termite. Made for exterior performance.

Not uniformly dense throughout.

No termite or rot protection MR MDF (moisture resistant MDF) offers moisture resistance for interior use only.

For Best Results

For best results, allow Extira to acclimate to the conditions it will be used in for 48 to 72 hours before final application or fabrication of a product using Extira. When designing products made with Extira, always allow for the natural expansion or contraction of Extira due to changes in its moisture content and assess interaction with other components in the final product. Like other wood composite material, the moisture content of Extira will change based on the ambient relative humidity and environmental conditions to which it is exposed.
