PlastiSpan® RN Insulation
Cost effective rigid insulation, recessed edges to fit strapping

PlastiSpan® RN Insulation is used in Continuous Insulation and Insulating Interior Basement Walls.


PlastiSpan® RN insulation applied to the exterior of above-grade wood
frame walls is a great way to increase the energy efficiency of that portion
of the home. PlastiSpan RN insulating sheathing is manufactured with the
long edges routed out to fit a 19 x 64 mm (1” x 3”) nailer for the
installation of exterior cladding.

PlastiSpan RN insulation installed over the exterior of wood frame walls
increases the effective thermal resistance (/RSIeff Reff) of the total wall
assembly because it eliminates thermal bridges due to wood studs
(which leave approximately 20% of the wall area without insulation).

• Contact us for other available thicknesses
• The addition of PlastiSpan RN insulation increases the RSIeff/Reff of a
wall assembly by eliminating thermal shorts due to wood studs which
leave a large portion of the wall area un-insulated
• Recessed edges to fit strapping
