Ductwork carries conditioned air through spaces that aren't conditioned — attics, ceilings, shafts, and rooftops. Without insulation, that air gains or loses heat before it ever reaches a room. J&M Mechanical Insulation insulates HVAC ductwork and system components so the air arrives closer to the temperature it left the equipment.
What we insulate
Typical duct insulation work includes supply and return ducts, outside-air intakes, vertical risers in mechanical rooms and shafts, and the elbows, transitions, and fittings that connect them. Rooftop ducts that are exposed to weather are usually insulated and then covered with a protective jacket.
Our job photos show the kind of detail this work requires: elbows wrapped and jacketed cleanly, and vertical risers insulated evenly from floor to ceiling.
Why duct insulation matters
Insulated ductwork helps an HVAC system deliver air at the intended temperature, which supports comfort and efficiency. On cooling systems, insulation with a sealed vapor barrier also helps prevent condensation from forming on cold duct surfaces, which can otherwise drip onto ceilings and finishes.
Duct insulation can also reduce some of the noise that travels through sheet metal. Where sound is a primary concern, see our soundproofing and acoustic insulation services.
New construction and retrofit
For new buildings and tenant improvements we work around the sheet-metal and mechanical schedule so ducts are insulated before ceilings and walls close. For existing buildings, we can assess ducts that were never insulated or where insulation has torn, sagged, or gotten wet, and provide an estimate to correct it.
