Weatherization Services

Hopkins Energy Corporation Weatherization Services

Our team of Weatherization technicians can diagnose and repair areas within your home that are along heat to escape.

The Weatherization process is started by taking a Building as a system approach. We look at how all of the components of your building work together.

Diagnosing the Building

The Weatherization team will use a set of specialized Building Diagnostic tools to help diagnose the deficiencies within your building.

Blower Door Diagnostics

Blower Door: A diagnostic tool designed to measure the air tightness of building.

These are also used to help locate areas of air leakage. A blower door consists of a calibrated fan for measuring an airflow rate and a pressure-sensing device to measure the air pressure created by the fan flow. The combination of pressure and fan-flow measurements are used to determine the building air tightness. The air tightness of a building is useful knowledge when trying to increase energy conservation, decrease indoor air pollution or control building pressures.

Air Sealing

Qualifying Air Sealing is covered 100% through our friends at MASS Save.

Air Sealing is the process holes within your building envelope that allow drafts into your home. The most effective areas of airsealing are found in your attic and basement ie. plumbing stack, electrical wires, plumbing chases, attic top plates and chimney chases.

Airsealing reduces the convective losses within your home. Convection is the transfer of heat by a liquid or gas (such as air). Circulatory air motion due to warmer air rising and cooler air falling is a common mechanism by which thermal energy is transferred. An open chimney flue provides a good example of convective heat loss during the winter. Warm air will rise up the chimney and cold air will fall down into the home. The energy used to warm the air that escapes is lost. The cold air must now be heated.

The greater the temperature difference between the inside and outside of the home, and the larger the openings in the home, the easier it is for air to move and the greater losses you will have due to convection. Convective heat loss occurs through cracks and holes in the home and gaps and voids in ceilings, walls, and floors—and in the insulation. Convection also occurs if air can circulate through the insulation — if insulation is to be effective, it must prevent air from flowing easily through it. Properly applied insulation reduces convective heat loss by resisting and minimizing air movement.

Insulation

We can easily add blown cellulose to your attic or walls with our specialized cellulose blowing machines.

The addition of insulation adds to your conductive values. Conduction is heat transfer through a material as thermal energy moves from molecule to molecule through a substance; or from one object to an adjoining object. If you pick up the handle of a cast iron frying pan from a hot stove you’ll experience conduction! The heat reaches your hand via conduction from the burner to the bottom of the pan through the metal handle to your hand.

Heat is conducted through the ceilings, walls and floors of homes. Effective insulation slows conduction by keeping heat out during summer and in during winter.
