Zehnder Authorized Sales & Service Center
We Design Ventilation and Air Purification Systems for Performance Buildings
Fresh Air is filtered through the Zehnder fresh air ventilation system and distributed for interior health, all the while incorporating heat recovery from the exiting air.
Experience a draft-free and radiantly-comfortable environment, in your own home! We are breaking thermal bridges, adding extreme air-tightness, and providing unmatched interior comfort.
Our Envelope Specialties allow for a reduced heater altogether, and a NET-ZERO result with less than half the normal PV system!
Imagine saving $200 a month on gas and electricity, and making that money work for you. One option is to reduce a 30-yr mortgage by up to 7 years!
MainStream has over 10 years practice in Passive House Green Building. Passive House is the easiest path to calculating and specifying off-grid, Zero Net Energy buildings of all shapes and sizes. Passive House is the only global industry of energy builders, modelers and experts studying the accuracy of actual performance. If you want to design a building with accurate predictions of real energy usage, you’ll want to use Passive House energy models and professionals. Certified Passive House buildings are:
Replace bathroom fans with nearly silent Zehnder whole building purification systems. We design, teach and test the only precise purified air delivery systems that use Energy Recovery (ERV) and Heat Recovery (HRV) to save 90% of wasted energy. When used with our Pro Clima Air Tight Envelope System, indoor air becomes allergy and asthma friendly.
We design, teach and test Air Barrier Systems for buildings of all sizes. These systems ensure a dust-free, longer lived, low energy loss envelope. With Pro Clima German engineered vapor open membrane system, easily achieve Passive House Airtightness with 100 year rated materials.
The New Zehnder ComfoAir Q purification system is the next generation of heat and energy recovery ventilation units, a “quantum” leap over conventional HRVs/ERVs currently available on the market. The Q builds on the superior performance and established success of Zehnder’s ComfoAir systems...
Two filter options are provided. Our standard filters are MERV 7/8 and a higher MERV 13 is also available for higher pollen protection on the unit’s intake.
It is suggested to change your filters twice a year and each unit uses two filters at a time.
Of all our Passive House Feasibility Studies, implementing the air barrier correctly is the key to success! Having air tightness, by that we mean 3 times tighter than Code requires, attributes to over half the energy savings alone.
We are happy to provide an estimate for your project. We will focus on the air barrier system and the tapes or membranes to use in your wall and roof assemblies. We will also include a fresh air system design with a layout for your floorplan. Simply upload your planset!
