McDaniel Metals 16X20X36 Plenum R8 M16X20X36R8

The McDaniel Metals M16X20X36R8 is a 16 by 20 by 36 inch plenum with R-8 insulation, for connection to furnaces and air handlers.

The R-8 insulation value is the significant specification. Where R-6 satisfies many jurisdictions, R-8 is the requirement in numerous energy codes for duct and plenums located in unconditioned space, and specifying it avoids a plan review or inspection issue on projects where the equipment sits in an attic, a vented crawl space, or an unconditioned garage.

The higher insulation value also improves condensation resistance. A supply plenum in cooling operation carries air well below the dew point of the surrounding space, and the greater the insulation, the further the exterior surface temperature stays above dew point. In humid climates and in equipment closets with limited air movement, this is what prevents the sweating and dripping that damages surrounding finishes.

R-8 additionally provides more acoustic absorption than R-6, attenuating blower noise at the point where it is generated. Where the equipment is close to bedrooms or a home office, that difference is audible.

Plenum dimensions must match the equipment outlet or be transitioned properly. An abrupt mismatch at the blower outlet creates turbulence, raises static pressure, and generates noise.

Applications include residential and light commercial furnaces, air handlers, and fan coils, particularly where equipment is located in unconditioned space.
