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.

Perfect day bag!
Color: Upgrade-black, Size: 15.6 Inch
Super convenient and lightweight. I used it for two back-to-back conferences last week and it was PERFECT for what I needed to tote along all day. Fits my regular sized computer (15-16 inch) and even held my water bottle (which is larger than a regular plastic water bottle).

Color: Upgrade-apricot, Size: 15.6 Inch, Color: Upgrade-apricot, Size: 15.6 Inch
Perfect for work! I use it for laptop, charger and few items necessary at work. I have a few blocks to walk from parking to work location and this bag has replaced last backpack and purse. Much easier to carry one item than two or more. Plus, it has enough room if you need to use it for clothes and toiletries (road-trip) or carry-on.
