Halfback® Foam Board Insulation 1 in x 4 ft x 8 ft R-4.7 GPS

Halfback Insulating Sheathing Insulation is a flat foam insulation used as an underlayment for board and batten, shakes and scallops.

• Can be used in conjunction with other insulated siding products.
• Treated with a systemic insecticide which protects the foam from termite damage and is safe for installers and home owners.
• Comes with a Lifetime Limited Warranty.

Neopor® has similar properties to EPS, but contains high-purity graphite particles which reflect heat as it passes through the insulation, slowing it down. This graphite gives our Premium Series insulation its super-efficiency and dark gray color.
