4FT x 50FT Thermal IR Blocker
A revolutionary new security product,
Block-IR is made from NASA developed Infra-Red blocking technology.
The two outer layers of Block-IR material reduce thermal imaging heat signatures by 97%.
Each layer if Block-IR material is bonded to a durable layer of polyurethane for strength.
An inner layer of insulation prevents conductive heat flow.
An additional layer of polyurethane gives Block-IR high reliability and strength.
