Energy Services Group FAQ
What type of insulation should I use?
There are many types of insulation, fiberglass, mineral wool. There is also spray foam which is an air sealer and insulation product all in one.
Do I need more insulation?
Currently the tri-state area is calling for R-49 in the attics or about 17 inches of total insulation.
Is my current insulation a health risk?
Not typically. If it is vermiculite, it may contain some asbestos which can cause cancer.
How do I prevent moisture from getting into the insulation?
Moisture on insulation in the attic is usually caused by a roof leak of some hot conditioned air is leaking into the cold attic in the winter months and this will cause condensation to form. It usually starts on the shingle nails and can drip onto the insulation on the attic floor.
Do I need to replace my insulation?
Only if it is contaminated with feces from rodents or is vermiculite which can cause cancer.
What is an energy audit?
An Energy Audit looks at the entire house. From the roof down to the foundation. We record the R values in the home in the attic, walls and on the foundation. We test the efficiency of the heater and the hot water heater. We measure the home to figure out the building air flow standard. A blower door test is performed to see record the building leakage. During cooler months we use a Thermal Camera to check for insulation in the walls and ceilings and to look for framing by passes which can lead to higher utility bills and comfort issues.
How long does an energy audit take?
Usually 2-4 hours.
What is air sealing?
Air sealing is just sealing the areas in a home that lead to infiltration leakage during the seasons. In an existing home it is usually performed in the attics, sealing the drywall to the top plates , capping framing voids, and sealing the penetrations made by the contractors when they ran their materials. (Electric, plumbing and HVAC) and in the basement/crawlspaces, sealing where the house sits on the foundation along with the penetrations. In new construction it is the exterior walls and all penetrations in the home along with the attic and basement/crawl space sealing.
Do I still need to air seal if I have insulation?
Insulation does not stop moving air, (unless it is dense packed). Insulation reduces heat loss only. To get the most return on your investment all homes should be air sealed before adding insulation. Aligning the thermal boundary and the insulation will deliver the most comfortable homes and reduce the cost to condition the home.
