Properly air Split Cartridge Seal such cracks

When fireplaces are not being used, they should be Pump Cartridge Seal with weatherstrip to air mechanical Cartridge Seal the damper and prevent wasted energy. The common perception should be that just like doors and windows, fireplaces require weatherstripping to prevent energy loss.

Like a door or window, fireplaces are openings to the outdoors and should be weatherstripped to prevent the loss of heated and/or cooled air. By weatherstripping the fireplace, several benefits are achieved including improved comfort, energy conservation, reduced energy costs, reduced noise, and improved indoor air quality.

Fireplace dampers are not effective at Mechanical Seal the fireplace. When dampers are closed they do not provide an air tight mechanical Cartridge Seal and are quite ineffective at controlling undesired air leakage. Most fireplace dampers are left open. A study showed that 80% of fireplace dampers are inadvertently left in the open position1. Many fireplaces have broken and/or missing dampers.

The majority of energy loss in the home is due to air leakage. Air leakage, or infiltration, occurs when outside air enters a house uncontrollably through cracks and openings. Properly air Split Cartridge Seal such cracks and openings in your home can significantly reduce heating and cooling costs, improve building durability, and create a healthier indoor environment.

Inadequately Split Pump Seal fireplaces are noted as being one of the worst air leakage sources in the home. According to the D.O.E.3, by weatherstripping the fireplace, the typical U.S. home can reduce air leaks by 14% or more.

According to 2004 US Census Data4, there are 76,217,000 family households in the U.S. By multiplying the number of family households by the typical savings possible by weatherstripping the fireplace, the total annual energy cost savings that can be achieved by weatherstripping fireplaces is $6,100,000,000.

Of course not every home in the U.S. has a fireplace. However this only serves to increase the energy cost burden for the homes that do have fireplaces.

Energy Codes in force across North America require that all openings in the building envelope (doors, windows, attic access, etc) be caulked, gasketed, weatherstripped, or otherwise Cartridge Sealed to limit air infiltration and exfiltration. This is because air leakage through cracks can result in higher energy use for home heating and cooling than necessary.

The 2000 International Energy Conservation Code is the latest version of the Model Energy Codes. It has been adopted either state-wide or in municipalities in 26 states, and specifies that all penetrations in the building envelope between conditioned and unconditioned space that are sources of air leakage must be Cartridge Sealed with durable caulking materials, closed with gasketing systems, weatherstripping or otherwise Pump Cartridge Seal to limit uncontrolled air movement.

Nearly all of the 50 states (as well as our territories) have adopted an Energy Code either the same as or based on a Model Energy Code. Model Energy Codes commonly used are the 2000 and 1998 IECC, or the 1992, 1993 and/or 1995 Model Energy Codes (MEC).
