High-Performance Thermal Insulation

Ultra-R™, Glacier Bay’s vacuum super insulation, delivers the maximum insulation
performance available on the market while using less space than traditional foam insulation. Ultra-R, with an R value
of R-36, provides 10 times the insulation value of foam, yet is only 1 3/8” thick. These panels rely on moderate vacuum and a special aerogel core material to achieve their insulation value rather than “trapped air” as do conventional insulation materials.
Ultra-R is a rigid, polypropylene-encased vacuum insulation panel custom-made to your dimensions. It can also be pur
chased with an optional fiberglass facing (on one or both sides).
Ultra-R offers many advantages over other thermal insulations including:
- Highest “R” value of any currently available insulation material
- Superior space and energy savings
- Exceptionally light weight
- Long life
- When combined with our ready-to-mount hatch lids, you can easily assemble your own ice boxes.
- Outstanding “R” value even if punctured
