What is mineral fiber insulation?
Properly installed mineral fiber insulation is a practical method to reduce the chance of wet pipe systems (or those that always contain water) from freezing. Below are illustrations to show some possible designs for insulation systems for fire sprinkler systems which contain water. Note there are many other acceptable systems which will reduce the chance of sprinkler systems freezing and the systems shown are not guaranteed to prevent pipes from freezing.
What is the property of insulation to slow heat flow?
Insulation’s property to slow heat flow is expressed as R-value. The greater the R-value the greater the ability to slow heat flow. It is important that the heating system remains on to supply heat to the building. If the heating system fails and the temperature goes below freezing for a long enough time the heat in the water will move to the colder areas and the pipes may freeze.
Does insulation stop heat flow?
Heat moves from warm areas to cold areas, and insulation slows the flow of heat. Insulation does not stop heat flow, so it is important that the pipes are installed in areas within or close to the heated part of the building and insulation is placed between the sprinkler system pipes and the colder outside.
How to prevent a sprinkler system from freezing?
The second means of preventing a wet pipe sprinkler system from freezing is by insulating the sprinkler pipe. Using insulation over the sprinkler pipe traps the flow of warm from the adjacent spaces.
What are the concerns with dry type sprinklers?
The first area of concern is the length of the barrel and the second is the distance between the face of the fitting and the inside surface of the exterior wall or insulation, whichever is closer to the fitting.
Why are sprinklers called dry sprinklers?
Dry sprinklers are so named because there isn’t any water in the pipe barrel until the system needs to operate. Instead, the dry pipe sprinkler features a barrel with a seal at the connection point to the wet pipe sprinkler system. Water does not enter the barrel until the sprinkler operates which releases the seal.
Does water enter the barrel of a sprinkler?
Water does not enter the barrel until the sprinkler operates which releases the seal. This keeps the part exposed to the freezing conditions dry and unable to freeze.
What is the NFPA 13 for fire sprinklers?
