Is Your Sacramento Home Under-Insulated?
Is your home more than 20 years old? Do you commonly find yourself feeling uncomfortable in your home during the cooler or warmer seasons? Do your heating and air conditioning bills seem higher than they should be? If you answered “yes” to any of these questions, you probably need to upgrade your home’s insulation.
It’s not surprising that most homes in Sacramento (and the United States) are under-insulated. Since insulation is typically hidden from view, whether inside walls, under floors or in attics, most homeowners simply forget it’s there. However, insulation plays a huge role in determining the comfort level of the home interior when the outside weather gets hot or cold. Insulation makes your home less conductive of outdoor temperatures and provides resistance to the flow of thermal energy attempting to enter your home. An insulation material’s effectiveness at resisting thermal energy is quantified as its R-value.
Besides thwarting the flow of hot/cold air into the living space, insulation also keeps mechanically heated and cooled (aka “conditioned”) air from leaving it. Since hot/cold air tends to travel toward more temperate areas in search of equilibrium, a poorly insulated home will provide plenty of easy escape routes for conditioned air to flee the scene. This will not only make the home less comfortable, it will also result in higher heating and air conditioning bills, as the HVAC system must continually replenish the escaping conditioned air.
To prevent this, insulation should be situated in several areas of the home. This includes:
- Inside exterior walls
- Beneath flooring
- On the attic floor
- In the wall between the garage and the living space
- In foundation walls and slab
- Over wall sheathing
While most homes have insulation in more prominent areas like the walls and attic, in many cases the insulation is of a low R-value and provides little thermal resistance. In such cases, it’s recommended to supplement the home’s insulation and bring it up to current standards.
Supplementing home insulation may be easy or difficult, depending on where it’s located and the specific circumstances. For instance, adding insulation to an unfinished attic is fairly simple because the insulation is already exposed, whereas supplementing wall insulation requires the walls to be opened up. That’s why, if you have plans to remodel your Sacramento home, you should take the opportunity to add insulation where convenient. For example, if you’re replacing your home’s siding, this offers a great opportunity to add blown-in insulation and insulative wall sheathing.
Whatever the situation, don’t overlook the vital role insulation plays in your home’s comfort level and energy efficiency. Call a professional insulation contractor to assess your home’s insulation and determine where more should be added.Read moreRead less
