Professional Insulation Services.
Commercial-grade insulation for ductwork, piping, pumps, and mechanical equipment. Reducing energy loss, preventing condensation, and lowering noise levels across commercial HVAC systems.
At a glance
Insulation at a glance
Condensation control
Continuous vapor barriers on chilled-water lines and cold ducts stop sweating, drips, and mold.
Thermal performance
Supply air and hot water arrive at design temperature instead of losing it in the ceiling.
Personnel protection
Hot piping and equipment surfaces insulated to protect maintenance staff.
Removable where it counts
Blankets on pumps and valves come off for service and go back on.
Ductwork Insulation
Icebox installs fiberglass insulation on supply and return ductwork for new installations and existing systems. Duct insulation reduces thermal loss between the air handler and the occupied space, maintains supply-air temperatures closer to design setpoints, and reduces condensation risk on cold ductwork running through unconditioned spaces.
Insulation thickness, density, and vapor-barrier requirements are determined by project specifications and applicable energy codes. All ductwork insulation is installed to maintain continuous coverage with sealed joints and intact vapor barriers.
Small detail, large consequences
Insulation is the cheapest part of the system to get wrong
A gap in a vapor barrier on a chilled-water line becomes a ceiling stain, then a mold call, then a tenant complaint. Icebox insulates ductwork, piping, and equipment with continuous coverage, sealed seams, and vapor barriers intact, and repairs sections that other trades have disturbed.
Insulation is typically installed alongside equipment replacements, tenant build-outs, and piping repairs, so thermal and moisture protection is restored at the same time the mechanical work is done.
- Supply, return, and exhaust duct insulation
- Chilled-water, hot-water, refrigerant, and condensate piping
- Pump, heat-exchanger, and valve blankets
- Vapor-barrier repair and replacement
- Re-insulation after equipment changeouts
Piping Insulation
Icebox insulates chilled-water lines, hot-water piping, refrigerant lines, and condensate drains for commercial HVAC systems. Piping insulation prevents energy loss on heated lines, eliminates condensation (sweating) on chilled-water piping, and protects against freeze risk in exposed locations.
Vapor-barrier integrity is critical on cold-side piping. Icebox installs insulation with continuous vapor-barrier coverage and sealed seams to prevent moisture migration into the insulation layer — the primary cause of insulation failure and downstream water damage.
Equipment & Pump Insulation
Mechanical equipment including pumps, heat exchangers, expansion tanks, and valve assemblies are insulated to reduce energy loss and protect personnel from contact with hot surfaces. Removable insulation blankets are used where access for maintenance is required, allowing technicians to service equipment without permanently disturbing the insulation.
Insulation Replacement & Repair
Existing insulation deteriorates over time due to moisture intrusion, physical damage, vibration, and modifications made during other trades' work. Icebox removes and replaces damaged or missing insulation on ductwork, piping, and equipment — restoring thermal performance and condensation protection to the original specification.
Common triggers for insulation replacement include equipment changeouts, tenant build-out modifications, roof leak damage, and sections disturbed during plumbing or electrical work.
Why Insulation Matters
Energy Efficiency
Insulation reduces thermal transfer between conditioned systems and the surrounding environment. Less energy lost in distribution means lower equipment runtime and reduced utility costs.
Condensation Prevention
Properly insulated cold-side systems with intact vapor barriers prevent condensation that causes water damage, mold, and corrosion in ceilings, walls, and mechanical spaces.
Noise Reduction
Insulated ductwork reduces airflow noise transmitted to occupied spaces. This is particularly important in office buildings, healthcare facilities, and other noise-sensitive environments.
Personnel Safety
Insulation on hot-water piping, steam systems, and equipment surfaces protects maintenance personnel and building occupants from accidental contact burns.
