Makeup Air Systems What goes out, must come in
| Makeup Air Systems MUAS Makeup Air System Why do we need makeup air? In a nutshell - we would otherwise have problems. Today's homes are built to be more energy-efficient. "Tighter" construction resists the infiltration of outdoor air through the home's exterior, which limits the amount of makeup air the home will permit. Of course, you can only exhaust out from the home as much air as is able to come back in.
Makeup Air Systems | 3 The Fantech Makeup Air System is the only solution A home builder could actually satisfy a home's makeup air requirement by leaving a relatively large hole (or several) in the exterior wall. Although, a hole in the wall might satisfy the makeup air requirement in the code, most would agree that such a solution is hardly ideal, especially during peak seasonal weather conditions. The "passive" solution is similar to the hole in the wall.

| Makeup Air Systems Colorado Homebuilder Meets Kitchen Makeup Air Requirement with Fantech Bruce Fraser of Fraser Construction LLC knows something that many builders do not. You can have a suitably sized kitchen exhaust system and still meet the IRC M1503.4 makeup air requirement without breaking the bank. This “good-to-know” information came as a result of a major kitchen addition/ renovation that Fraser completed at a home just west of Vail, Colorado, in the upscale community of Cordillera.
