Foam pipe insulation is a barrier that prevents thermal transfer between the fluid inside a pipe and the outside air.

R-value attic insulation is a measure of thermal resistance, which indicates how well a material slows heat flow.

R13 insulation is used primarily in wood-framed walls and requires a thickness of three and a half inches.

Install insulation by filling structural cavities with thermal barriers like fiberglass batts or spray foam.

Foil insulation is a radiant barrier that reflects heat radiation away from a surface.

Floor joist insulation is fiberglass batt or mineral wool installed between the structural members.

Attic baffles insulation are channels that maintain a clear path for air to flow from the soffits to the ridge vent.

Bubble wrap window insulation is a thermal barrier that uses trapped air pockets to reduce heat transfer.

R19 insulation is a thermal resistance rating typically achieved with fiberglass batts at a thickness of 6.25 inches.

Exterior wall insulation is applied as a continuous layer of material like expanded polystyrene (EPS) or mineral wool onto the outer face of the building envelope.

Curtain insulation is a barrier that traps a layer of still air between the window and the room.

Insulation for 2×4 walls is comprised of fiberglass batts, mineral wool, or spray foam.

Vapor barrier insulation is placed on the warm side of the assembly to prevent water vapor from entering the wall cavity.

Insulation and mold occur when water enters a building envelope through air leaks, roof penetrations, or high humidity.
