Tightly sealed, energy efficient homes are great for conservation, but bring a new challenge to home builders – namely, finding a way to replenish the air exhausted by the kitchen vent hood. When the new IRC M1503.4 building code requiring make-up air (MUA) for range hoods in excess of 400 CFM was introduced, builders had few cost-effective compliance options – everything required re-engineering, special tools or methodologies that slowed productivity down.
Now, there’s a better solution: The Residential Make-up Air System (RMAS) (PATENTED US 9,263,214 B2) by CCB Innovations. This universal fresh air infiltration system takes the complications, worries and high costs out of meeting the IRC M1503.4 make-up air code compliance.
