ENERGY WASTE IN

BUILDINGS TODAY

A recent ASHRAE report shows 75% of buildings have leaky ductwork, helping make HVAC

the biggest source of energy waste.

BUILDINGS ARE BLOWING

ENERGY DOLLARS AWAY!

Increased Fan Energy

Poor Air Quality

High Energy Bills

The more air that leaks out of your ducts, the harder your fans have to push to reach the desired space. Duct leakage leads to excess ventilation loads, which in turn drastically increases your energy costs.

Leaks in the return duct allow airborne allergens, viruses, and bacteria to be sucked into the duct system. These contaminants are then spread throughout the facility, compromising air quality for other occupants.

Leaky ductwork is the primary cause of ineffective building exhaust, causing problems with uneven and uncomfortable temperatures that can lead to higher energy bills, and added maintenance costs.

Airtight Ducts. Airtight Returns.

Reduce Energy Costs


Duct Sealing addresses multiple sources of energy waste. For example, by reducing leaks 15%, fan requirements drop by 40% or more. This saves thousands of dollars every month. Duct Sealing increases HVAC fan efficiency and eliminates excess ventilation load to reduce energy costs. It is a verifiable and guaranteed way to offer energy savings with typical payback in two to five years.




Improve Building Ventilation


Leaky ductwork is the primary cause of ineffective building exhaust. In addition to causing problems with uneven and uncomfortable temperatures, this can lead to higher energy costs, and added maintenance costs.




Improve Indoor Air Quality


Leaks in the return duct allow dust and other contaminants to be sucked into the duct system and spread throughout the facility. And exhaust fans can’t remove contaminated air from the building if there are leaks in the ventilation shaft.




Meet Code & Spec


As duct leakage specifications get tighter and tighter, Duct Sealing is specified as a routine component of commercial projects. Duct Sealing offers consistent results and will take you from hoping to knowing that you’ll meet code requirements – the first time
