These codes are put in place to improve energy efficiency, reduce utility costs, and maintain comfortable indoor environments throughout the year—just like our insulation! Michigan homeowners can rest easy knowing their attics, walls and floors are filled with the best insulators on the market, with everything up to code.

Circulating Hot Water Systems

One of the crucial requirements outlined in Michigan's insulation codes pertains to circulating hot water systems. According to the code, circulating hot water systems shall be insulated to at least R-2. This requirement is aimed at minimizing heat loss from hot water pipes, thus improving the overall efficiency of the system.

Insulating circulating hot water systems to at least R-2 can be achieved using various insulation materials such as foam pipe insulation or fibreglass pipe wrap. These materials provide thermal resistance, preventing heat from escaping the pipes and ensuring that hot water reaches its destination without unnecessary energy loss.

Additionally, Michigan's insulation code stipulates that these systems must include an automatic or readily accessible off-switch. This safety feature allows for easy shutdown of the circulating hot water system when necessary, further optimizing energy usage and ensuring compliance with state regulations.

Supply & Return Ducts in Attics

Another critical aspect of Michigan's insulation code relates to the insulation of supply and return ducts in attics. When ducts are located outside conditioned space, such as in attics, they must be insulated to a minimum of R-6. This requirement helps prevent heat loss or gain through the ductwork, ensuring that conditioned air remains at the desired temperature as it travels through the system.

Moreover, when ducts are located outside the building’s thermal envelope, the insulation requirement is increased to at least R-8. This higher level of insulation helps maintain the efficiency of the HVAC system by reducing energy losses associated with ductwork located in unconditioned spaces.

To meet these insulation code requirements in Michigan, various insulation materials can be used, including fibreglass duct insulation, rigid foam insulation, or spray foam insulation. Proper installation of insulation around supply and return ducts in attics helps improve overall energy efficiency and ensures compliance with state regulations.
