New homes have an amazing number of penetrations on their sides. On the side of a typical Shane home you will find a combination of windows, doors, furnace vents, hot water tank vents, fireplace direct vent, bathroom fan vent, hood fan vent, dryer exhaust, electrical meter, gas meter and air conditioner. These vents, meters and appliances must be carefully spaced to prevent fires, keep exhaust gases from entering the home and maintain proper appliance function. Understanding that the placement of these elements in relation to each other is tightly regulated is important as it could affect the design and cost of your new home.
