The Marwin C ompany “R-10 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.
Helps meet the following LEED categories:
Energy and Atmospheric credit 2.2 (Enhanced Insulation Exceeds
IEC C by 5%)
Energy and Atmospheric C redit 3.1 (Minimal Envelope leakage)
TO O R D ER :
The Marwin C ompany “R-10 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-10 ENERGY SAVER” insulating
package at the time of order.
