Data from the Insulation Institute shows that around 90% of American homes have inadequate home insulation. In general, having good insulation means your home is running efficiently, leaving a low carbon footprint. When heated or cooled air is kept inside the house due to proper insulation, HVAC costs drop significantly. In households that use an HVAC system, heating and cooling take up most of the electricity usage. That’s why good insulation easily translates to savings in the long run.
Understanding insulation and how it works in conjunction with your HVAC system
There are different types of materials used for insulation. Each type of material is rated accordingly on how well they can keep a home insulated. A certain R-Value is given to insulating materials so homeowners can know which type is best. The higher the R-Value, the better the material is at insulating a home and keeping Florence HVAC costs down. A good thing to note, though, is that the optimal R-value changes from one region to another. For instance, states with harsher winters typically require a higher R-value than states with moderate winter months. You may know more about R-Value from your local HVAC contractor.
A comparison of insulation ratings
You can find a lot of different materials for home insulation. Not all of them have the same capacity, though. That’s why it is best to seek the advice of experts like Florence HVAC Experts on the matter. Here’s a breakdown of some insulation materials and their respective R-Value per inch.
- Batts and blankets – these are made from either rock wool or fiberglass and provide an R-Value of around 3.1-4.0.
- Blown-in loose fill – this type of insulation can also be made from rock wool, fiberglass, or cellulose. Blow-in loose-fill insulation typically offers an R-Value of 2.4-4.0.
- Rigid foam – there are different types of rigid foam insulation. Some are made from polyurethane, polystyrene, or polyisocyanurate. Normally, rigid foam insulation provides an R-Value of 3.5-7.5.
- Spray foam – a common type of insulation material used nowadays is spray foam. It is also made from either polyurethane or polyicynene and provides an R-Value of 3.6-7.0.
Best locations to add insulation
HVAC ducts – the ductwork requires insulation to prevent air from leaking out. Your HVAC system has a lot of components that work together to push cool or heated air around the house. It is important to keep air circulated inside the house without any leakage.
The floor of an unfinished attic – if your attic is unfinished, be sure to insulate the floor. This will form as a barrier which minimizes heat transfer from the room below. Also, be sure to insulate the access door to avoid any leakage.
Walls and ceiling of the finished attic – in case you use your attic as a home office or any other application, be sure that both the walls and the ceiling are insulated.
