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 for protecting my maps
Size: Regular - 12 x 16 Inches
Fits my exploring maps just right. Heavier duty than expected. Ziplock closure is tight and should last for years.

Terrific addition to your backpacking gear
I like this map holder for its versatility in holding different size maps. Once sealed, it was very effective at keeping moisture out and protecting the maps. I originally used this on a 13K mountain ascent. Worked great. The only thing that can be tricky at times is sealing the top. It's not as easy as sealing a typical zip-loc kitchen bag, takes some doing to get it to seal.

Best Map Case Ever!!!
Size: Regular - 12 x 16 Inches
Best Map case in the market! Field tested and keeps everything dry. The size is fantastic and you can run paracord through the rings. I would recommend this to anyone that uses a map. You definitely pay for what you get and that's high quality and functionality.
