Trusted Best Insulation for Masonry Walls in Zones 1 & 2
As a multi-layer reflective wall insulation, VR Plus Shield™ enhances enclosed cavity air space, stopping up to 97% of radiant heat transfer. This unique insulation has multiple Low-e layers that expand within the cavity to create three (3) reflective air spaces. Gain up to R-7.1 on minimum 1-1/2″ framing for a higher-performance wall system.
An easy upgrade from R-4.1 insulation to help builders qualify for DOE New Energy Efficient Home Tax Credits. Cost-effective and remarkably easy to install, this powerful multi-layer Low-e technology boosts R-value by utilizing less cavity air space—allowing for a slimmer wall system to provide you with more sellable square footage in zones 1 & 2.
A Cost Effective Alternative to 3/4″ Foam Board
One (1) roll of VR Plus Shield™ equals 16 sheets of 4×8 foam board. Packaged in compact 500 sq ft rolls, this offers easier handling, reduces waste, and lowers the chance of product damage due to weather when staged on job sites.
