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.
