Altra-Seal is another great product from Sun-North. Altra-Seal (similar to Altra-Wall) was developed for dual ventilated livestock housing providing the best of both worlds.


Key Benefits:

  • Works with or without mechanical ventilation
  • Superior weather/air seal
  • Reducing power consumption
  • Operates in the event of power failure
  • Low Maintenance
  • Provides an R12 or R20 insulation value

    Altra-Seal is manufactured in one style (single sliding panel) and in one colour (black). We have designed and manufactured this product to give our clients the best of both worlds.

Dual ventilation is the supply of minimum ventilation using exhaust fans and a controlled inlet system during colder weather, switching to natural ventilation by sidewall openings during moderate & warm weather, resulting in:

  • Reasonable operating costs
  • Very good cold weather ventilation
  • Less dependent on weather conditions
  • High summertime ventilation rates at low cost
  • Well suited to small, more sensitive pigs
  • Less management intensive

    Altra-Seal is an R12 & R20 insulated sliding panel system. It is a lightweight, durable, continuous, rigid sliding panel. Altra-Seal works well with mechanical ventilation systems on double wide buildings.
