The ECHO Basement Finishing
System

Pioneered by Dr. Douglas Walkinshaw,
President of Indoor Air Technologies, an Ottawa-based company
specializing in indoor air quality, ECHO comprises ventilated perimeter
finished walls built on the inside of the foundation and optional
subfloors. ECHO is designed to combat water leaks, humidity and soil
gases that enter foundations.

- Enclosed Conditioned HOusing system -

Using
a small variable speed blower, 10-100 CFM, consuming 10 to 85 watts,
air is continually exhausted to the outside from the sealed and fully
insulated ECHO walls and low E floors at a low rate. This combination
creates a negative pressure barrier around the basement living space,
preventing soil gas and moisture entry, and keeping insulation and
materials dry. And since air in the envelop is
constantly ventilated, soil gases such as radon do not enter the house.

ECHO comprises specially sealed, ventilated, depressurized, drained and
insulated stud walls and optional sub-floors, covering the foundation
where basement thermal, moisture, mold and soil gas problems begin.
ECHO SYSTEM air quality improvements reduce ventilation requirements
thereby eliminating the need for air-to-air heat exchangers. ECHO
construction increases usable living space while preventing basement
dampness and musty odors. ECHO Prevents soil gas entry and reduces
basement heating and dehumidification requirements.

The ECHO
System protects your loved ones and your investment through system
drainage, dehumidification and material isolation from concrete.

KEY BENEFITS
- Unlike HRVs and
standard exhaust ventilators, ECHO dehumidifies in rainy and humid
weather.
- ECHO eliminates
basement pollutants such as microbial spores and gases at the
source, thereby reducing house ventilation requirements and
eliminating allergy problems.
- ECHO provides
whole house ventilation with heat recovery while eliminating
envelope moisture problems.
- ECHO creates
healthy living space from unhealthy basement space, thereby
eliminating the need for a costly addition and additional heating
and cooling costs.
- ECHO eliminates
1-2 gallons per day of soil moisture entry through the foundation,
thereby reducing house dehumidification requirements.
- ECHO keeps
insulation dry and eliminates energy robbing convection currents
thereby increasing subfloor and perimeter wall thermal resistance.
