Features
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

Benefits
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.

To Order
The Marwin Company "R-5 ENERGY-SAVER" insulating package can be easily added to any model stairway. Select any of our Wooden or Aluminum models and ask for the "R-5 ENERGY-SAVER" insulating package at the time of order.

Great buy!
Size: Medium, Color: (001) Black / Black / White
My husband loves these. The socks are warm and thick and extremely comfortable. They support the foot and he works outside all day and has had them for a little over a month. They stay in place and don’t move move around while he’s outside moving around.

Good quality
Size: Large, Color: (035) Steel / White / Black
These are a bit thicker then a compression sock and they come up higher on the ankle than a no-show sock normally does. They are very comfortable and soft.
