The different types of roof insulation present in a home, will depend on the type of roof installed. Some people prefer the common type of roll in roof insulation, while others request the foam, or spray in type of insulation. Regardless of the type of roof insulation installed, it is very important to have a roof of a home insulated.
The roof is generally constructed of a certain amount of evenly spaced wooden two by fours commonly referred to as joists and rafters. Rafters lie parallel and have the same amount of space between. Joists lie intersecting to the rafters, and are used to secure the weight of the rest of roof, which rests on the outer frame of the home construction. Roll in roof insulation is designed to fit in between each and every rafter.
When blown insulation is used for roof insulation, there is not a lot of storage area left in the attic. This type of insulation is blown out of a machine, and fills the entire area of the attic or crawl space located directly above the ceiling of the home. This is the easiest way to insulate a roof, but it is not the most efficient.
No insulation under the roof is sometimes and option, but this option is definitely not a recommendation. Roof insulation not only traps heat, but it protects the lower floors of a home, in case of a roof leak, or roof damage.
A new house that is not equipped with any type of roof insulation will become quite costly each and every month, by causing excessive heating and utility bills. Heat rises to the highest secure place in the home, no matter what type of heating is used. Therefore, the roof insulation is used to secure the highest part of the home. Meaning, the heat will be trapped inside the attic or crawl space due to the presence of a good type of roof insulation.
Most roof insulation is extremely itchy when it comes into contact with human skin. Therefore, anyone that is installing any type of insulation should dress accordingly. Simply stated, a roof insulation installer should wear apparel which will cover most of the skin area which will come in contact with the insulation. Breathing apparatus should be used as well, because some roof insulation contains particles of fiberglass which can cut the soft tissue of the lungs if inhaled.
In conclusion, roof insulation come in many different choices. An already existing home should have the roof insulation monitored periodically to make sure there are no new leaks in the roof. A new home should most definitely have some sort of insulation put in. Roofs can be very costly to replace, and preserving the remainder of the home is very important.
