R-5 Energy Saver Insulating Package


  • Factory installed certified R-5 insulated door system
  • Extra 1/8” hardboard cover to protect the insulation from damage (code requirement in some areas)
  • Factory applied “Bulb” type, perimeter weather-stripping
  • Taped edges around the insulation to protect and minimize R-value loss


  • Meets or exceeds the new energy code requirements
  • The Marwin Company "R-5 ENERGY-SAVER" insulating package means your stairway is ready to install without any insulating problems or wasted time.
  • Our factory installed insulating panel is more durable and less likely to become damaged. Damaged insulation reduces its efficiency.
  • Our factory applied weather-stripping has the following properties:
    • Helps reduce air leaks and can withstand temperatures of up to 275 degrees Fahrenheit.
    • Assures a proper seal, by remaining pliable, with low memory retention for long lasting service. Other PVC weather-stripping may become stiff and crack or split.
    • Is securely fastened and won't peel off or curl-up like most adhesive backed, field applied, "foam" weather-stripping.
