Get your shed an upgrade with insulation to keep your shed comfortable all year long. The Foil-Faced Foam Sheathing board is rigid polyisocyanurate foam sheathing that provides exceptional heat, humidity, and air control to protect your building's exterior walls and, when installed correctly, eliminates all major thermal bridges that cause heat loss. And fiberglass insulation is paper-faced also to provide moisture control, effectively control heat flow, and keep unwanted noise from entering your shed. Your shed will be your place-to-go place when you can turn it into a Outdoor Oasis with Johns Manville insulation.
