After forty years of innovation, Kohltech has established itself as an industry leader in both Canada and the United States. They are committed to creating high-performance windows and entrance systems, which allowed them to achieve the rigorous certification standard of the Passive House Institute US.

Kohltech is currently one of 11 manufacturers in the world to have certified entrance door products as well.
Originating in Germany, Passive House (Passivhaus) is a very rigorous standard for energy efficiency in a building. In order to be eligible for Passive House, houses must meet the following standards:
- The building must be designed to have an annual heating and cooling demand as calculated with the Passivhaus Planning Package of not more than 15 kWh/m2 (4,2755 BTU/ft.; 5.017 MJ/sq. ft.) per year in heating or cooling energy OR be designed with a peak heat load of 10 W/m2 (1.2 hp/1000 sq. ft.)
- Total primary energy (source energy for electricity, etc.) consumption (primary energy for heating, hot water and electricity) must not be more than 120 kWh/m2 (38,040 BTU/sq ft; 40.13 MJ/sq ft) per year
- The building must not leak more air than 0.6 times the house volume per hour (n50≤ 0.6 / hour) at 50 Pa (0.0073 psi) as tested by a blower door, OR alternatively when looked at the surface area of the enclosure, the leakage rate must be less than 0.05 cubic feet per minute
- The specific heat load for the heating source at design temperature is recommended, but not required, to be less than 10 W/m2 (3.17 BTU/h.ft2)
